Description

Technical Field

[0001] The present invention relates to the technical field of pressure test cushions, and in particular to a pressure test cushion customized based on a sitting posture cushion and a pressure detection method thereof. Background Art

[0002] Traditional seat cushions need to be tested and customized before being used for the injured, sick, disabled, elderly and other disabled people, so that targeted seat cushions suitable for different disabled people can be selected. Conventional test seat cushions mostly test the sitting pressure value through pressure sensors. Most pressure sensors are fixed in a certain position, which limits their detection range and cannot detect patients in different sitting postures and orientations. At the same time, they cannot adapt to all users, resulting in some users being unable to obtain accurate pressure monitoring data when using seat cushions.

[0003] Therefore, in order to address the problem that most of the above-mentioned pressure sensors are fixed in a certain position, which limits their detection range and makes it impossible to detect patients in different sitting postures and orientations, resulting in the inability to obtain accurate pressure monitoring data, a pressure test cushion customized based on a sitting position cushion and a pressure detection method thereof can be designed. Summary of the invention

[0004] In order to overcome the problem that most pressure sensors are fixed in a certain position, so that their detection range is limited and they cannot detect patients in different sitting postures and different orientations, resulting in the inability to obtain accurate pressure monitoring data.

[0005] The technical solution of the present invention is: a pressure test cushion customized based on a sitting posture cushion, including a cushion body; also including a detection component and a ventilation component, a detection component for detecting a pressure value is installed inside the cushion body, the top of the cushion body is movably connected with a ventilation component, the detection component includes a control box, the control box is arranged on the rear side of the cushion body, a motor is arranged inside the control box, the output end of the motor is connected with a screw rod, and two groups of screw rods are relatively arranged and connected through a transmission belt, the top of the screw rod is slidably connected with a sliding block, and the top of the sliding block is installed with a pressure sensor.

[0006] Preferably, the control element inside the control box is started to rotate the screw rod, driving the sliding block and the pressure sensor to slide horizontally, and the pressure value when sitting is monitored in real time through the pressure sensor; the control unit receives the pressure detection signal from the pressure sensor, and processes and analyzes it to obtain the pressure distribution of the sitting position.

[0007] Preferably, a sponge is installed at the bottom end of the seat cushion body, and a screw rod is arranged in the sponge. A support plate is arranged at the top of the pressure sensor, and supports are arranged at the four corners of the top of the support plate.

[0008] Preferably, a support rod is installed in the middle position of the top end of the support, a memory spring is sleeved on the outer side of the support rod, and a memory foam is arranged on the top end of the support plate.

[0009] Preferably, the ventilation assembly includes a back cushion, which is movably connected to the top of the seat cushion body, and fan boxes are installed on the front and rear sides of the back cushion.

[0010] Preferably, three sets of ventilation fans are arranged inside the fan box, an air outlet end of the fan box is connected to a ventilation duct, and an air outlet end of the ventilation duct is arranged inside the seat cushion body.

[0011] Preferably, a cool mat is provided on the surface of the back cushion.

[0012] Preferably, memory foam, a pressure sensor and sponge are sequentially arranged inside the back cushion.

[0013] The pressure detection method of the pressure test cushion customized based on the sitting posture cushion comprises the pressure test cushion customized based on the sitting posture cushion as described above, and the steps are as follows:

[0014] The first step is to install the pressure test cushion on the test seat, make sure the cushion is in a horizontal state, and then the patient sits on the cushion to ensure that the buttocks are in full contact with the cushion. The control element inside the control box is activated to rotate the screw rod, driving the sliding block and the pressure sensor to slide horizontally, and the pressure value during sitting is monitored in real time through the pressure sensor.

[0015] In the second step, the control unit receives the pressure detection signal from the pressure sensor, processes and analyzes it to obtain the pressure distribution of the sitting posture;

[0016] The third step is to transmit the analyzed and processed data to the information service platform, and formulate a customized cushion suitable for matching the patient based on the data and the basic conditions of the patient on the information service platform;

[0017] In the fourth step, patients can compare cushion parameters more vividly and intuitively, and ultimately choose the assistive device that suits them. When summarizing users’ historical receipts, the platform aggregates, deeply analyzes, and conducts information research on the data.

[0018] The beneficial effects of the present invention are as follows: the pressure sensor is driven to move horizontally by the setting of the screw rod and the sliding block, so that when testing the patient, the pressure distribution on the cushion can be monitored in real time, which helps medical personnel to promptly discover the patient's potential pressure problems. At the same time, the position can be adjusted as the user's sitting posture changes, so as to continuously provide accurate pressure monitoring data and accurately locate the area where pressure is concentrated, making the test effect more accurate. Patients can realize personalized pressure monitoring according to their needs and preferences and choose a customized cushion that is more suitable for them. BRIEF DESCRIPTION OF THE DRAWINGS
