Description
Technical Field
The invention relates to the technical field of medical appliances, in particular to a pressure injury prevention mattress used on a flatcar.
Background
The pressure injury is a common problem faced by the global health care institutions, and not only can bring great pain to patients and seriously reduce the life quality of the patients, but also increases the medical cost and consumes a large amount of medical resources. The surgical patients are high risk groups of pressure injury, and the incidence rate is as high as 4.7% -66.0%. Patients with general anesthesia after operation generally experience anesthesia recovery time of 60-80 min on a flatcar, and the risk of pressure injury of the patients is greatly increased due to residual effects of various anesthetics and muscle relaxants and the influence of preoperative malnutrition, long-time braking in operation, operation wound, blood loss, fluid loss, pain and the like. Common methods for preventing stress injury during recovery from anesthesia include: turning over, foam-rubber cushion, elastic foam, silica gel, gel mattress, etc. The defects are that:
1. during the anesthesia recovery period, the vital signs of the patient are not stable, the patient is possibly dangerous at any time, at the moment, the patient is more dangerous to move, and the patient is difficult to turn over due to the reasons of manpower, space and the like of the anesthesia recovery room.
2. The sponge cushion which is commonly used clinically has poor air permeability, is easy to form local concave for a long time, and sweat, blood and the like of a patient are easy to accumulate, so that the local skin of the patient is moist and tissue blood stasis can be caused, the occurrence of pressure injury is caused, and the occurrence of nosocomial infection can be possibly caused.
3. Elastic foam, silica gel or gel mattresses are impractical due to their high price and are only used by a very small number of hospitals in China.
The pressure applied to different parts of the human body is different when the human body lies on the back, the risk of forming pressure injury is different, when the pressure applied to local tissues exceeds the capillary average pressure by 32mmHg, ischemic hypoxia necrosis can occur, and when the pressure exceeds 70mmHg and lasts for 2 hours, irreversible tissue cell change can be caused. Studies have shown that the maximum pressure exerted by the sacral caudal region during recumbency is about 83mmHg, the shoulder and heel regions are 32mmHg and 18mmHg, respectively, and the occurrence of pressure injury to the sacral caudal region is about 70.12% of the total hospital-acquired pressure injury. The patient on the flatcar can only lie in the prone position, so that the risk of pressure injury on the sacral tail of the patient on the flatcar is obviously higher than that of other parts, in addition, different patient sizes are different, the support pressure required by the body is different, but the pressure injury prevention mattress commonly used in clinic is fixed in shape, the positions of all pressure support points after inflation are also fixed, the experience of the patient is poor, and the effect of preventing the pressure injury is limited; the intelligent air cushion bed with adjustable pressure can adjust the pressure of air cushion bed inflation according to the pressure of each part of human body, can effectively prevent the occurrence of pressure injury, but the price is expensive, the practicality is poor, and the intelligent air cushion bed is not suitable for clinical application.
In addition, the existing air cushion bed can only use alternating current, and cannot be used when no alternating current or alternating current is powered off, so that application occasions are limited to a large extent, and if the power is off in the use process, the mattress cannot be inflated, and a patient can directly sleep on the hard bed board, so that pressure injury is more likely to occur.
