Background technique

Pressure-resistant vitreous excision joint Intraocular padding is to treat the only effective hand of complicated retinal detachment in recent years Art method, and in order to make reattachment of retina, selectively silicone oil or expanding gas are injected intraocularly in art, treated to consolidate operation Effect, prevents the generation of postoperative complications, and postoperative Most patients (except the ceasma of top) need to keep position downwards for a long time, It is specifically to maintain this special posture 12-16 hours/day, effect is to maintain ceasma and is in highest order, utilizes silicone oil and gas Upward buoyancy and surface tension press closing retinal hole, achieve the purpose that promote reattachment of retina, while correct face Downward position can also avoid silicone oil or gas from entering anterior chamber and glue before causing corneal edema, pupillary block, intraocular hypertension, iris The generation of the postoperative complications such as company, secondary angle-closure glaucoma.So position is surgical effect success or not downwards for holding Key point.

Most traditional measure of Body position nursing care downwards is as follows: using ordinary hospital bed, using prone body position, Head And Face pad one Airfilled ring prostrate is on bed.But the traditional measures have following obvious deficiency: after head is fallen, sky that airfilled ring is enclosed Between it is substantially sealed off, it is airtight, make patient generate sensation of asphyxia.

For this purpose, devising a kind of dedicated hospital bed of retina postoperative care again in row, the bed board and mattress of the dedicated hospital bed are opened Equipped with one and the matched slotted eye of face size, the face of patient can be allowed to lie prone on the slotted eye edge in this way, than Relatively efficiently improve the smooth breathing of prone position.But this above-mentioned slotted eye measure only improves the ventilative problem of nasal cavity, There are still following problems:

One, patients with cervical posture is single, unadjustable change, causes cervical vertebra to be ached over time hard to bear, especially for Cervical vertebra natively for problematic retina postoperative patient, even more adds hardship in hardship；Specifically, the pitching degree on head is non-adjustable Section changes, and change, the unadjustable change of the vertical position of face are adjust and reform towards non-differentiability in the left and right on head；

Two, for some patientss especially adolescent patient, since forehead or lower jaw part natively have acne or skin Skin inflammation causes forehead and lower jaw part in great pain in addition front lying position makes forehead and lower jaw part be pressurized for a long time, or even is formed red Swollen pressure sore；

Three, front lying position makes chest, face persistently by upward pressure, cause uncomfortable in chest, expiratory dyspnea, heart compression without It is suitable.

Above-mentioned three aspects problem causes some patientss even cannot adhere to prone body position and lead to the hand that affects the treatment or even make Art failure, or cause postoperative complications, and open up slotted eye in mattress and be helpless to alleviate above-mentioned chest continuous compression, face The problem of portion's continuous compression.

Four, since the mattress of hospital bed opens up slotted eye, thus to may be only available for retina postoperative patient dedicated for the hospital bed, And it is poorly suited for its ophthalmic patient, when ophthalmology inpatient department is less or be zero in the retina postoperative patient ratio in certain periods When, which can only supply the postoperative general patient of non-retina and use, and in such cases, slotted eye can give it instead His general patient brings uncomfortable or inconvenient.
