Description

Technical Field

[0001] The utility model relates to a bedsore prevention pad, in particular to a lumbar support bedsore prevention mattress. Background Art

[0002] At present in the market, the bedsore prevention air cushion generally only has an alternating function and can normally solve the bedsore problem of patients. For the existing bedsore prevention pad with such an alternating function, due to design defects in the structure and principle of the mattress itself, during normal use, the force on each part of the body is not uniform. Specifically, there is less support for the waist. In fact, the force is mainly borne by the buttocks and back, and there is a lack of force support for the waist. Therefore, long-term use by users will cause waist soreness. Thus, how to solve the above technical problems has become an urgent technical problem to be solved. Content of the Utility Model

[0003] The technical problem to be solved by the utility model is to provide a lumbar support bedsore prevention mattress with a simple structure design, convenient operation, which can effectively relieve waist discomfort and also has a massage effect.

[0004] To solve the above technical problem, the lumbar support bedsore prevention mattress of the utility model includes an air pump for inflating the airbag of the mattress. The air distribution end of the air pump is connected with a three-way joint. One air outlet of the three-way joint is connected with the airbag through a rotary valve and can make the airbag alternately inflate and deflate. The other air outlet of the three-way joint is connected with a lumbar support that supports at the waist position of the human body through a solenoid valve.

[0005] The solenoid valve is a two-position three-way solenoid valve.

[0006] The lumbar support has an arched cross-section structure.

[0007] The lumbar support is arranged at the middle position of the mattress.

[0008] The advantages of the utility model are as follows:

[0009] Due to the three-way joint provided and the lumbar support which is connected through a solenoid valve at one of the air outlets of the three-way joint and supports at the waist position of the human body, when a patient needs to periodically support the waist to relieve waist discomfort, the circulation mode can be used. This mode can not only provide support for the waist, but also play a certain massage role. When the support strength for the patient's waist is moderate, the pressure holding mode can be switched to provide long-term force support for the user and relieve waist discomfort. When the patient does not need to use the support, the mode is switched to the no-pressure mode. Its structure design is simple, the operation and use are convenient, effectively relieving the waist discomfort effect and having a certain massage role. Description of the Drawings

[0010] Figure 1 It is the schematic diagram of the lumbar support bedsore prevention mattress of the utility model;

[0011] Figure 2 This is the principle block diagram of the lumbar support anti-bedsore mattress of the present utility model. Specific embodiments

[0012] The following further describes the lumbar support anti-bedsore mattress of the present utility model in detail in conjunction with the accompanying drawings and specific embodiments.

[0013] As shown in the figure, the lumbar support anti-bedsore mattress of the present utility model includes an air pump 2 for inflating the airbag 1 of the mattress. The air distribution end of the air pump 2 is connected with a three-way joint 3. One air outlet of the three-way joint 3 is connected to the airbag through a rotary valve 4 and can alternately inflate and deflate the airbag. The other air outlet of the three-way joint 3 is connected with a lumbar support 6 that supports the human waist through a two-position three-way electromagnetic valve. In addition, in order to improve the support effect, the lumbar support 6 has an arched cross-section structure and is arranged in the middle of the mattress, so as to support the human waist. Using this lumbar support anti-bedsore mattress can realize three modes: (1) lumbar circulation mode; (2) lumbar pressure maintenance mode; (3) no-pressure mode;

[0014] Specifically, when the patient needs to periodically support the waist to relieve lumbar discomfort, the circulation mode can be used. This mode can not only provide support to the waist, but also play a certain massage role;

[0015] When the lumbar support strength of the patient is moderate, actually switch to the pressure maintenance mode to provide force support to the user for a long time and relieve lumbar discomfort;

[0016] When the patient does not need to use the support, switch the mode to the no-pressure mode.

[0017] Its working principle is as follows:

[0018] Under normal circumstances, the air pump 2 inflates the single and double tubes of the mattress to achieve the anti-bedsore function. At this time, the two-position three-way electromagnetic valve is in the normally closed state;

[0019] When the electromagnetic valve is powered on, the electromagnetic valve is connected to the air cushion of the lumbar support. The air pump 2 inflates the lumbar support through the three-way joint and the electromagnetic valve to achieve the support function and realize the lumbar pressure maintenance mode;

[0020] When the electromagnetic valve loses power, the electromagnetic valve is normally closed. At this time, the lumbar support is in the deflated state until the pressure is 0, which is the no-pressure mode;

[0021] When the electromagnetic valve is periodically powered on and off, the lumbar support will be periodically inflated and deflated, so as to realize the lumbar circulation mode.

[0022] Certainly, the above description is not a limitation to the present utility model, nor is the present utility model limited to the above examples. Changes, modifications, additions or substitutions made by those skilled in the art within the substantial scope of the present utility model shall also fall within the protection scope of the present utility model.
