Description

Technical Field

[0001] The utility model relates to a medical product, in particular to an anti-pressure sore pad. Background Art

[0002] Because patients stay in bed for a long time, they are prone to bedsores, also known as pressure sores, on the protruding parts of the buttocks. It is caused by long-term pressure on the local skin of the body, which affects blood circulation, leading to skin and subcutaneous tissue nutrition deficiency, resulting in damage, ulcers and even necrosis. It is prone to occur in the protruding parts of the bones under pressure, such as the sacrum and coccyx, which are common parts, mainly due to the patient staying in bed for a long time. At present, there are many solutions, such as the use of airbag cushions, which is one of the common solutions. The main design of the air cushion is an air cushion with the same area as the bed body, and the raised air columns distributed continuously in the longitudinal or transverse direction of the air cushion form a wave shape. When in use, the air cushion is placed on the bed body and inflated with an air pump. Then the patient lies on the air cushion. Because the air cushion has a certain softness and elasticity, it is used to relieve the pressure between the patient's body and the air cushion, reduce the incidence of pressure sores, and play a certain role. However, although the raised air column on the air cushion is wavy, it forms a plane or concave reverse support force under the pressure of the patient's body, which increases the body contact surface and does not reduce the non-contact space with the air cushion. In this way, long-term pressure contact and local non-air permeability also cause pressure sores, and the occurrence of pressure sores cannot be effectively avoided. Therefore, developing a method to effectively avoid the occurrence of pressure sores has become an urgent problem to be solved. Utility Model Content

[0003] In view of the current status of the above-mentioned technology, the utility model provides an anti-pressure sore pad, which can not only be placed in parallel for use, but also can be connected to form a ring-shaped air cushion, which can avoid the contact between the patient's protruding parts and the air cushion, and can also meet the patient's turning over with a follow-up function, avoiding the need for assistance from nursing staff.

[0004] The technical solution of the utility model is: an anti-pressure sore pad, including an air cushion; wherein the air cushion has at least two or more air bags, which are connected to each other through distributed air passages and spaced into a plurality of hollow strip-shaped air cushions; zippers are provided on the ends of both sides of the air cushion, and a ring-shaped air cushion is formed after being connected by the zippers. When in use, the strip-shaped air cushion is placed horizontally on the bed at the position of the patient's buttocks, and the protruding part of the patient's buttocks is placed in the hollow position between the air bags so that it does not contact the protruding part of the patient. In this way, the probability of pressure sores caused by local pressure is avoided. When the nursing staff leaves, the air cushion will be closed into a ring-shaped air cushion by a zipper, and the patient can turn over by himself, and the ring-shaped air cushion can rotate accordingly, keeping the hollow position between the air bags always corresponding to the protruding part of the patient.

[0005] In the present invention, the airbags on the air cushion are divided into a main airbag and a transition airbag; the inflation cavity of the main airbag is larger than the air cavity of the transition airbag.

[0006] In the present invention, the hollow interval between the airbags is 12-15 cm.

[0007] In the present invention, the interval between the airways is 12-15 cm.

[0008] In the present invention, the zipper is a split zipper. Thus, a closed annular air cushion is formed after the zipper is closed. The air cushion can rotate synchronously with the body, making it convenient for the patient to turn over and change the compressed position.

[0009] The beneficial effect of the utility model is that the strip-shaped air cushion is placed horizontally and parallelly on the bed, so that the protruding part of the patient's buttocks is placed in the hollow position between the air bags and does not contact the protruding part of the patient. Since the contact between the protruding part of the patient and the air cushion is solved, the probability of pressure sores is avoided. In addition, the air cushion can also change shape. When the nursing staff leaves, the air cushion will be closed into a ring-shaped air cushion through a zipper. When the patient turns over by himself, the ring-shaped air cushion can rotate synchronously with it, so that the hollow position between the air bags always corresponds to the protruding part of the patient.

[0016] The present invention will be further described below with reference to the accompanying drawings.

[0017] See Figures 1 to Figure 2The anti-pressure sore pad shown in the figure comprises an air cushion 1, on which a first air bag 2 and a second air bag 5 are arranged. A plurality of air passages 3 are distributed between the first air bag 2 and the second air bag 5, and are connected to each other and spaced into a plurality of hollow strip-shaped air cushions A. An inflation nozzle 6 is provided on any of the air bags, and is inflated by an inflation pump (not shown in the figure). When in use, the strip-shaped air cushion is placed horizontally on the bed at the position of the patient's buttocks, and the protruding part of the patient's buttocks is placed at the hollow 7 position between the first air bag 2 and the second air bag 5, so that it does not contact the protruding part of the patient. In this way, the probability of pressure sores due to local pressure is avoided.

[0018] In the above, zippers 4 are provided at both ends of the air cushion 1, and a ring-shaped air cushion is formed by connecting through the zippers 4. When the ring-shaped air cushion is used, when the nursing staff leaves, the air cushion will be closed into a ring-shaped air cushion through the zipper 4, and the patient can turn over by himself, and the ring-shaped air cushion can rotate accordingly, so that the hollow positions between the air bags always correspond to the protruding parts of the patient.

[0019] In the above, the interval between the hollows 7 between the airbags is 12-15 cm.

[0020] In the above, the interval between the airways is 12-15 cm.

[0021] In the above description, the zipper 4 is a split zipper.

[0022] See Figure 3 Another embodiment of the air cushion of FIG1 is given. It is different from FIG1 in that it is modified accordingly based on the structure of FIG1, that is, a first transition airbag 8 and a second transition airbag 10 are provided. The first transition airbag 8 is connected to the adjacent first airbag 2 on the air cushion 1 through the first transition air duct 9, and is separated by multiple hollows; the second transition airbag 10 is connected to the adjacent second airbag 5 through the second transition air duct 11, and is separated by multiple hollows. Other identical parts such as the first airbag 2, the second airbag 5, the air duct and the zipper 4. Multiple hollows are formed between the first airbag 2, the second airbag 5 and the air duct.

[0023] The first airbag 2 and the second airbag 5 are main airbags; the first transition airway 8 and the second transition airway 11 are transition airbags. That is, the inflation cavity of the main airbag is larger than the cavity of the transition airbag. In this way, the height difference between the body and the bed is reduced through the first transition airway 8 and the second transition airway 10 to maintain comfort.

[0024] Figure 4A reference diagram of the use state of the strip air cushion in Figure 1 is provided. The inflated air cushion 1 is placed horizontally on the bed 12 and flattened, and the buttocks of the patient 13 are placed on the first airbag 2 and the second airbag 5 of the air cushion 1. If the patient 13 is lying on his side, the protruding part of the buttocks of the patient 13 is placed in the hollow position between the first airbag 2 and the second airbag 5, so that the protruding part of the buttocks is suspended and does not contact the first airbag 2, the second airbag 5 and the bed 12. This avoids the occurrence of pressure sores caused by the first airbag 2, the second airbag 5 and the compressed bone protrusion.

[0025] Figure 5 The reference diagram of the annular air cushion in use is given in Figure 1. The inflated air cushion 1 is placed horizontally on the bed 12 and flattened, and the patient's buttocks are placed on the air cushion 1 (the placement position is the same as that of the Figure 4 The same). If the patient 13 is lying on his side, the protruding part of the buttocks of the patient 13 is placed on the hollow position between the first and second airbags, so that the protruding part of the buttocks is suspended and does not contact the first and second airbags and the bed. After the placement is completed, the edge of the air cushion 1 is bent and connected, and the zipper 4 on it is tightened and closed to form a ring-shaped air cushion. In this way, when the patient 13 needs to turn over to the side position, the ring-shaped air cushion will also rotate synchronously, so that the hollow position on the air cushion 1 is always located at the protruding part of the patient's buttocks.
