Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a pressure-reducing mattress and an operating table. Background Art

[0002] Pressure sores, also known as pressure injuries and bedsores, are open injuries caused by prolonged pressure, friction, shear force, etc. on the skin and subcutaneous tissue, which causes continuous ischemia and hypoxia of local tissues, leading to cell metabolism disorders and tissue necrosis. Pressure sores are common in patients who are bedridden for a long time, have difficulty in moving, have lost sensation, or are physically weak, such as the elderly, paralyzed patients, and patients in intensive care. Pressure sores mainly occur on bony prominences, such as the sacrum, heels, and scapula. They can be divided into four stages according to their severity, from the erythema stage, blister stage, superficial ulcer stage to deep ulcer stage. In severe cases, they can invade muscles, bones, and even internal organs. At present, when patients undergo long-term surgery, they are in a passive position for a long time in order to fully expose the surgical site, which can easily cause pressure sores or the formation of venous thrombosis, causing damage to the patient's body, and even threatening the patient's life in severe cases. Currently, most hospitals use gel mattresses, cotton pads, etc. to protect against pressure injuries, but the effect is general. For operations with long operation time and heavy bleeding, it will still cause pressure damage to the patient's skin, and the occurrence of skin indentation, redness, swelling, and blisters cannot be avoided.

[0031] Example 1

[0032] like Figure 1 As shown, this embodiment provides a pressure-reducing mattress, including a mattress body 100 , a supporting airbag 200 , an air pump 300 , a pressure sensor, and a control module 400 .

[0033] The support airbag 200 is arranged on the cushion body 100, and there are multiple support airbags 200. The air inlet and the air outlet of the support airbag 200 are provided with a stop valve; the air pump 300 is respectively connected to each of the support airbags 200; the pressure sensor is arranged in the support airbag 200; the control module 400 is respectively electrically connected to the pressure sensor, the air pump 300, and the stop valve; the pressure sensor can transmit the received pressure data to the control module 400; the control module 400 can control the opening and closing of the air pump 300 and each of the stop valves.

[0034] During use of the pressure relief mattress provided in this embodiment, the patient to be treated lies on the mattress body 100, and each part of the patient is pressed on the corresponding support airbag 200. At this time, the support airbag 200 is in a concave state, and each part of the patient can press the pressure sensor in the corresponding support airbag 200. The pressure sensor is compressed to generate pressure data, and the pressure data is transmitted to the control module 400. At this time, the medical staff observes the pressure data received by the control module 400 on each part of the patient. When the pressure value of a certain part of the patient is too large, the medical staff can The patient's lying position can be adjusted as needed to reduce the pressure on the part. When it is inconvenient to move during surgery or treatment, the medical staff can open the stop valve on the air inlet of the support airbag 200 at the part with excessive pressure through the control module 400, close the stop valve at the air outlet of the support airbag 200, and then control the inflation pump 300 to start inflating the support airbag 200, so that the support airbag 200 can lift the part with excessive pressure without affecting the medical staff's surgery or treatment of the patient, thereby reducing the pressure on the part of the patient and avoiding pressure injury to the part of the patient.

[0035] During the above-mentioned use process, medical staff can accurately know the pressure conditions of various parts of the patient lying on the pressure relief pad according to the control module 400, so as to carry out targeted pressure adjustment on various parts of the patient, effectively reduce the probability of pressure sores in various parts of the patient's body, and ensure the health of the patient.

[0036] In some embodiments, the plurality of support airbags 200 respectively form a first decompression group 500 and a second decompression group 600; each of the support airbags 200 of the first decompression group 500 is used to provide decompression support for a patient in a supine position; each of the support airbags 200 of the second decompression group 600 is used to provide decompression support for a patient in a prone position; by setting up the first decompression group 500 and the second decompression group 600, it is possible to detect pressure data of the patient's prone areas of pressure sores and lift up and decompress the areas when the patient is in different lying positions.

[0037] Specifically, the support airbags 200 of the first decompression group 500 are respectively arranged on the rear part 510 of the headrest, the left shoulder 520, the right shoulder 530, the sacrum 540, the left heel 550, and the right heel 560 of the cushion body 100; that is, due to long-term pressure on the patient, the parts that are most likely to develop pressure sores include: the head, left shoulder, right shoulder, sacrum, left heel, and right heel. When the patient lies on the cushion body 100 in a supine position, the support airbags 200 of the first decompression group 500 can respectively provide support to the patient's head, left shoulder, right shoulder, sacrum, left heel, and right heel, and perform pressure detection on these parts and reduce pressure as needed, so that the pressure detection of each easily pressurized part of the patient in the supine position is more accurate, thereby improving the decompression effect on the easily pressurized parts.

[0038] Specifically, the support airbags 200 of the second decompression group 600 are respectively arranged on the head and face 610, chest area 620, left knee 630, right knee 640, left foot face 650, right foot face 660, left ilium 670, and right ilium 680 of the cushion body 100; that is, due to long-term pressure on the patient, the parts that are most likely to develop pressure sores include: face, chest area, left knee, right knee, left foot surface, right foot surface, left ilium, and right ilium. When the patient lies on the cushion body 100 in a prone position, the support airbags 200 of the first decompression group 500 can respectively provide support to the patient's face, chest area, left knee, right knee, left foot surface, right foot surface, left ilium, and right ilium, and perform pressure detection on these parts and reduce pressure as needed, so that the pressure detection of each easily pressurized part of the patient in a supine position is more accurate, thereby improving the decompression effect on the easily pressurized parts.

[0039] Of course, in other embodiments of the present invention, other decompression groups may be provided on the cushion body 100 , and the plurality of support airbags 200 may be arranged with respect to other lying positions of the patient and related parts of the other lying positions of the patient.

[0040] In some embodiments, the control module 400 is provided with a display screen 410 and an operation panel 420; the control module 400 can display the received pressure data and the inflation status of each of the support airbags 200 on the cushion body 100 on the display screen 410, so that medical staff can more intuitively determine the pressure status of various parts of the patient and the use of this embodiment, and the medical staff can accurately issue instructions to the control module 400 by operating the operation panel 420, and then control the opening and closing of the stop valves on the inflation pump 300 and each of the support airbags 200, which is easy to operate; of course, in other embodiments of the present invention, a microphone can also be provided on the control module 400, and the microphone can receive voice commands from medical staff, so that the medical staff can directly output instructions to the control module 400 through voice commands during the operation, and then control the vacuum pump and the stop valve of this embodiment, so as to improve the use efficiency of this embodiment.

[0041] In some embodiments, the operation panel 420 is preset with buttons corresponding to the positions of the support airbags 200. By pressing the corresponding button, the inflation pump 300 can be individually controlled to inflate the corresponding support airbag 200. This is convenient for medical staff to directly issue instructions to drive the vacuum pump to inflate the support airbag 200 corresponding to a part of the patient displayed on the control module 400 when they observe that the pressure on that part is too high, thereby lifting and decompressing the part. The operation is convenient and quick.

[0042] In some embodiments, the operation panel 420 is also preset with buttons corresponding to the first decompression group 500 and the second decompression group 600. By pressing the button corresponding to the first decompression group 500 or the second decompression group 600, the control module 400 can be used to drive the inflation pump 300 to simultaneously inflate the various support airbags 200 at the corresponding parts of the first decompression group 500 or the second decompression group 600; this is convenient for medical staff to quickly inflate the corresponding support airbags 200 according to the different lying positions of the patient, and to lift and decompress various parts of the patient, which is convenient and efficient to operate.

[0043] In some embodiments, the control module 400 is also preset with an automatic mode, that is, the control module 400 is preset with pressure size and pressure duration thresholds. When the value of the pressure data transmitted by the pressure sensor to the control module 400 is too large or the pressure data of a fixed value is transmitted for a certain period of time, the control module 400 can drive the air pump 300 to inflate the support airbag 200 where the pressure sensor is located, so as to facilitate the automatic lifting and decompression of various parts of the patient, so that the patient can achieve automatic decompression when lying down for a long time and there are no medical staff around, further reducing the probability of pressure sores in the patient and alleviating the patient's pain; of course, when performing surgery on the patient or restricting the patient from changing position at will, the medical staff can turn off the automatic mode as needed to avoid affecting the surgery or the patient's treatment.

[0044] Specifically, a timing device is provided in the control module 400, and the timing device can start timing when the pressure sensor in the support airbag is subjected to pressure and the pressure is transmitted to the control module, and the data is converted through the control module, and finally a relationship diagram between the pressure size and the pressure time of the patient's pressured part is displayed on the display screen, so that medical staff can accurately understand the pressure size and pressure time of a certain part of the patient by observing the display screen, so as to make timely adjustments to the patient's lying position or use the control module to drive the support airbag at the patient's pressured part to lift up the part and reduce the pressure on the part, thereby further reducing the probability of the patient developing pressure sores due to maintaining a lying position for too long and a certain part of the patient being under pressure for too long, and avoiding the formation of open injuries to the patient's local tissues due to cell metabolism disorders and tissue necrosis due to continuous ischemia and hypoxia.

[0045] In some embodiments, the pad body 100 is made of a polyurethane material that is foamed once. The polyurethane material that is foamed once has good load-bearing capacity and pressure dispersion ability, which can reduce pressure injuries caused by lying down for a long time. At the same time, it also has good resilience, wear resistance and is easy to clean and disinfect. Of course, in other embodiments of the present invention, the pad body 100 can also be made of memory foam, carbon fiber and other materials.

[0046] In some embodiments, a silicone pad is laid on the pad body 100 to improve the friction and wear resistance of the upper surface of the pad body 100 .

[0047] In some embodiments, a plurality of air holes 110 are evenly distributed on the cushion body 100 to improve the overall air permeability of the cushion body 100, thereby preventing the patient from developing eczema and prickly heat due to lying down for a long time, and ensuring the patient's health.

[0048] In some embodiments, the control module 400 is externally connected to an alarm component; specifically, the alarm component includes a speaker and an indicator light, so that when the pressure on a certain part of the patient is too great, the control module 400 can control the alarm component to issue an alarm reminder to the medical staff, that is, the speaker's sound reminder or the indicator light is on, etc., to facilitate the medical staff to respond quickly, so as to adjust the patient's lying position in time or decompress the patient in time through this embodiment.
