Description

 The invention relates to medicine, namely to medical equipment used mainly for the treatment of burn patients.

Known bed designs:
1. Medical stretcher bed for the treatment of patients with thermal skin lesions.

 Certificate for utility model 11062 dated 09.16.99. Class A 61 G 7/57.

 2. Mesh bed for the treatment of patients with thermal generation of the skin. Certificate for utility model 8248 dated 11/16/98. Class A 61 G 7/057.

 3. A bed for burn patients USSR 424566, A 61 G 7/057, 1974.

 A disadvantage of the known beds is that a metal mesh with mesh sizes of 2x1x0.4 mm is used as a bed, the mesh size is too small and does not allow the patient to be sanitized from the back without turning it, and pressure is applied to pressure-prone areas across the entire surface and while there is no adequate level of microcirculation of integumentary tissues, which leads to the appearance of pressure sores and diaper rash.

 When sheets are placed under a patient, adhesion to wounds is possible. To avoid adhesion, gauze dressings (dry or moistened with a solution of antiseptics) are necessary, which, in turn, reduces the effectiveness of treatment, reduces the aeration process, and complicates patient care. At the bed by A.S. USSR 424566 bed made in the form of a frame with sections of solid material.

Famous beds:
1. On a Clinitron airbag, Sypport Systems, France, French Patent 2523841, Class A 61 G 7/04, 1982;
2. Bed - RF patent 2026048, class A 61 G 7/057, 1991 - a bath with a diffuser bottom, filled with microspheres and granules of a carbon sorbent introduced as a bactericidal additive to kill microbes.

 3. Bed medical and burn and anti-decubitus KM-04 "Saturn-90". Joint serial production of Pnevmostroymashina JSC and Rhythm LLP, Yekaterinburg.

 The bed is made in the form of a bath with a porous diffuser bottom, covered with a filter screen, filled with microspheres of sodium-calcium glass, which, under the influence of an upward flow of purified air, pumped through the diffuser into the bath, acquire pseudo-fluid properties.

 Air flow passing through a layer of beads creates a sterile microclimate around the patient. The buoyancy effect reduces contact pressure on the patient’s body, eliminates pressure sores, and improves the quality of treatment.

The disadvantages of these beds are:
1. Frequent replacement of microbeads, as when infected liquid (sweat, feces, blood, etc.) enters the bath, microbes form, which, together with the air stream, enter the patient.

 2. High cost - up to 900.0 thousand rubles. The proposed bed costs from 15.0 to 20.0 thousand rubles.

 As the closest analogue (prototype) of the invention taken "Bed for burn patients" and.with. USSR 424566, A 61 G 7/057, 1974.

The disadvantage of this bed is that:
1) the bed of the bed consists of a frame with sections of solid material, which complicates the flow of dry air to the affected tissues and does not allow the patient to be sanitized from the back without turning it over;
2) the presence of a frame lifting mechanism in the form of a cable transmission causes the appearance of metal dust from friction when the cable moves.

 The objective of the invention is to create a simple bed design that eliminates the listed disadvantages in the treatment of burn patients, which makes it possible to effectively treat extensive circular burns and lesions, improve the sanitary treatment of patients at a lower cost and effort of the staff.

 This goal is achieved by the fact that it offers a functional burn bed, containing a frame on 4 supports, removable backs, a swivel bed, a sectional mattress of 3 pillows, a medicine table, swivel wheels with brakes, swivel bearings for upper limbs, air springs for tilt bed with manual control and lever drive, fan heater, infusion rack, Balkan supports, liquid tank, bed base made of kapron filament twisted-woven mesh with a mesh size of 10x10 mm, mounted on the bed n pins, are designed as a rod with a spherical head formed trapezoidal rotating bed, is disposed above the floor at a height of human growth medium hands.

 Analysis of patent and scientific and technical literature allows us to conclude that the proposed technical solution in the claimed invention meets the criteria of "Novelty" and "Significant differences".

 The invention is illustrated by drawings, where in Fig. 1 is a layout diagram, in Fig. 2 is a main view, in Fig. 3 is a side view, in Fig. 4 is a top view, in Fig. 5 is a pin, in Fig. 6 is a support for the upper limbs.

 Functional burn bed “Burn” contains: frame 1, wheels 2, swivel bed 3 of trapezoidal shape, pivotally connected to frame 1, removable bed base 4 from nylon twisted-woven mesh, supports 5 for upper limbs, air springs 6, tilting the bed into Fowler –Trendlenburg position, pneumatic spring control handles 7, removable backrests 8, fan heater 9, moisture-proof sectional mattress 10, removable “Balkan supports” 11, infusion stand 12, fixed to any of the backs, medicine table and medical equipment 13, eat bone for fluid 14, pins 15 for securing the base of the bed, brakes 16.

 The bed is a spatial supporting structure, consisting of a frame (item 1) on 4 supports, on which all the main elements of the product are hung.

 The frame is mounted on 4 wheels with twin brakes (item 2).

 One of the crucial elements of the bed is the trapezoidal swivel bed (item 3). The trapezoid allows to spread the patient's legs and provides him with proper comfort in case of damage to the hip and lower limbs. For the upper limbs, supports are provided. The base of the bed and supports for the upper extremities (item 5) is a removable nylon filament twisted-woven mesh (item 4) with a mesh size of 10x10 mm. The mesh is fixed to the bed with the help of pins (pos. 15), forming a flat surface.

 A positive effect in the application of kapron filament knot-free twisted-woven mesh in combiological practice is achieved by the fact that due to the cellular structure of the bed, optimal conditions are provided for aeration enhanced by a fan heater, drying of burn surfaces, speedy mummification of non-viable tissues, inhibition of wound microflora, which, ultimately, virtually eliminates the appearance of diaper rash, the development of local and general purulent-septic complications.

 The rapid mummification of non-viable tissues, in turn, significantly reduces the resorption of wound toxins, increases the reparative activity of the affected tissues.

 In the complex treatment of severe burn patients, local treatment is one of the most important. The use of kapron filament twisted-woven with a mesh size of 10x10 mm mesh allows you to successfully cope with this task.

 Spun-woven nylon filament with a mesh size of 10x10 mm mesh distributes pressure to pressure-sensitive areas not over the entire surface, but partially, while maintaining an adequate level of microcirculation in the integumentary tissues, which virtually eliminates the occurrence of pressure sores and diaper rash in patients.

Mesh nylon bed facilitates the care of seriously ill patients, increases the comfort of bed rest, conducting sanitary and hygienic procedures, treating the back surfaces of the body, allows the patient to be examined without turning it, and to monitor the course of the wound process. The nylon twisted-woven mesh is simple and easy to handle, easy to sanitize and relatively inexpensive. If necessary, a hole is cut out in the mesh and physiological settings are carried out without moving the patient. To accelerate the healing process and aeration, the bed is equipped with a fan heater (item 9), which supplies warm air (25-40 ^o С) to the affected tissue area.

 For the comfort of the patient, the bed is equipped with three pillows (mattress) (pos. 10) made of moisture-resistant leather. Pillows are placed under areas of the patient’s body with intact skin. The shape of the pillows repeats the "geometry" of the bed, i.e. trapezoidal.

The bed rotates to the Fowler-Trendelenburg position (Fig.2-4), which allows the medical staff, without turning the patient, to process wound surfaces. The height of the bed above the floor is 900mm, and is designed for average human height, an additional rotation of ± 15 ^o provides an opportunity to carry out medical procedures while the doctor sees damaged areas of the body. To adjust the bed to the Fowler-Trendelenburg position, two air springs (pos. 6) with manual control and lever drive are used. The drive handles (key 7) are located on both sides of the bed. The inclusion of air springs is carried out by lifting the handle up. To fix the bed in the raised state, the handle is lowered. To lower the bed, you need to raise the corresponding handle up with one hand, and press the edge of the bed down with the other. Moreover, if the patient is on the bed, the bed can fall itself under the influence of the patient’s weight without additional effort. If the patient is lying on the bed and the bed needs to be raised, then the handle is lifted up with one hand, and the bed is raised with the other. The lifting force is reduced due to the efforts of the air springs.

 The bed has two quick-detachable backs (pos. 8) of a closed shape, as well as two "Balkan supports" (to create a thermal tent) (pos. 11), an infusion stand (pos. 12), a container for liquid (pos. 14), which is installed under the net in the pelvic area.

 The use of the proposed bed in practice contributes to a more effective and high-quality treatment of burn patients, makes the process less painful and time-consuming, improves the quality of sanitary treatment of patients.
