Description

Balloon Radial Artery Tourniquet

technical field

The utility model relates to a medical device, in particular to an air bag type radial artery tourniquet.

Background technique

Coronary interventional therapy via the radial artery is a safe and effective technique for the diagnosis and treatment of coronary heart disease, acute myocardial infarction, atherosclerosis, myocardial ischemia and other diseases, because it is highly accepted by patients with minimal trauma, but Improper postoperative hemostasis can easily lead to complications such as bleeding at the puncture site, pain, subcutaneous bruising, blisters, numbness, swelling, and even arterial occlusion, and ischemic necrosis of the operated limb. At the same time, the limitations of the compression method can easily affect the daily activities of the patient, causing urinary retention, back pain, anxiety, sleep disturbance, and reducing the comfort of the patient.

At present, the most widely used radial artery hemostasis method in clinical practice is the use of balloon arterial tourniquet. The design principle is: the airbag is made of polyvinyl chloride material, which is transparent. The airbag can position and compress the puncture point, and achieve hemostasis by increasing the amount of gas. The braking time of the wrist joint after surgery is as short as 4-8 hours. But the traditional balloon type arterial tourniquet has the following disadvantages:

(1) The inflation and deflation action of the airbag is completed through the injection syringe, which is inconvenient to operate. The control of the inflation and deflation volume depends entirely on the experience of medical staff to judge, which affects the hemostatic effect, easily reduces the patient's comfort, and will increase the burden on nurses. workload;

(2) The airbag that compresses the patient's bleeding point needs to be inflated and deflated during use, and the airbag will be displaced during the inflation and deflation process, so that it cannot completely match the patient's bleeding point, resulting in poor hemostatic effect.

Utility model content

The purpose of the utility model is to overcome the shortcomings and deficiencies of the prior art, and provide a balloon type radial artery tourniquet with reasonable structural design, good hemostatic effect, and convenient and flexible inflation and deflation.

In order to achieve the above object, the technical solution of the utility model is to include an inflatable airbag, and also includes an inflated closed airbag for compressing the hemostasis point. The two sides of the inflatable airbag are detachably and fixedly provided with wide bandages. The inflatable airbag is connected with an electric air pump through an air delivery tube, and the compression surface of the inflated closed airbag for compressing hemostasis is set facing the inflatable airbag.

A further arrangement is that the inflated closed airbag is detachably connected to the inflatable airbag by Velcro.

It is further provided that the wide strap is a wide elastic strap.

A further setting is that both sides of the inflatable airbag are provided with connecting buckles for detachable connection with the wide strap.

It is further provided that the electric air pump is provided with a timing deflation control circuit for timing deflation control of the inflatable air bag.

The working principle of the utility model is: taking the radial artery to stop bleeding as an example, the bleeding point of the radial artery is facing the inner surface of the inflated closed air bag, then the wide bandage is wrapped around the human arm and the inflated closed air bag and the inflatable air bag Binding and fixing on the human arm, the electric air pump inflates the inflatable airbag, so that the inflated closed airbag indirectly bears force and compresses the bleeding point to achieve the hemostatic effect.

The utility model has the advantages of:

(1) By setting an inflated closed airbag to directly act on the hemostasis point, and the inflatable airbag will not change its volume shape and position during the inflation process, so the compression surface of the inflated closed airbag can be matched with the bleeding point of the human body , improve the hemostatic effect;

(2) The electric air pump is used for the inflation and deflation operation, which is easy to operate, and the electric air pump can be combined with the controller to realize the functions of timing automatic deflation or quantitative inflation, and realize automatic control;

(3) The detachable connection between the inflatable airbag and the wide strap is convenient for disassembly and washing, and it is hygienic and safe to use.

The utility model will be further introduced below in conjunction with the accompanying drawings of the description and specific embodiments.

Fig. 1 is a schematic structural diagram of a specific embodiment of the utility model.

detailed description

The following examples will specifically describe the utility model, which are only used to further illustrate the utility model, and cannot be understood as limiting the protection scope of the utility model.

The specific embodiment of the utility model shown in Figure 1 includes an inflatable airbag 1, and also includes an inflated closed airbag 2 for compressing the hemostasis point, and both sides of the inflatable airbag 1 are detachably and fixedly provided with The wide bandage 3 is connected to the electric air pump 4 through the air delivery tube 41 on the inflatable air bag, and the compressive surface used for compressing hemostasis on the inflated closed air bag 2 is set facing the inflatable air bag 1 .

Specifically, the inflated closed airbag 2 described in this embodiment is detachably connected to the inflatable airbag 1 through the Velcro 21 . With this setting, the velcro can keep the position between the inflated closed airbag 2 and the inflatable airbag 1 fixed, and can assist in improving the position accuracy of the inflated closed airbag 2 when used for hemostasis.

In addition, the wide bandage 3 described in this embodiment is preferably a wide elastic bandage, so that it can be used by people of different body types, and also improves the comfort of wearing the hemostat.

Both sides of the inflatable airbag 1 described in this embodiment are provided with connecting buckles for detachable connection with the wide binding strap 3 .

The Velcro or the connecting buckle described in this embodiment are commonly used connecting accessories well known to those skilled in the art, and can be directly purchased from the market, and will not be described in detail in this embodiment.

In addition, the electric air pump 4 described in this embodiment is provided with a timing deflation control circuit for timing deflation control of the inflatable airbag. With the development of electric control technology, there are already a large number of mature electric air pumps 4 with electric control functions available in the market for this embodiment. Air volume information display, etc. These solutions can all be applied to the technical solutions of the present application, and belong to the same or similar technical concepts of the present application, and therefore, should also fall within the protection scope of the present application.
