Description

Technical Field

[0001] The invention relates to the technical field of nursing beds and relates to a semi-automatic auxiliary turning mechanism. Background Art

[0002] At present, whether in the ICU ward or other departments of the hospital, or in nursing homes or even in some families, there are people with mobility problems and who cannot take care of themselves, and there are also people who are paralyzed in bed and have lost consciousness. What makes it difficult for nursing staff and family members is that it is difficult for patients to turn over. Nursing staff must use manpower to turn patients over regularly to prevent patients from sleeping in the same position for too long, which causes poor blood flow and even bedsores. It is actually very laborious for nursing staff to turn patients over manually. Because some patients are too heavy, it even takes two people to turn them over.

[0003] Although there are some auxiliary turning devices installed on nursing beds to help nursing staff to turn patients, this kind of auxiliary turning only tilts the bed board to one side at a certain angle through a motion mechanism, and the bed board tilts with the patient at a certain angle, and then the nursing staff turns the patient over and adjusts the sleeping position.

[0004] This method of turning over only slightly reduces the force used by the nursing staff when turning over the patient, but after turning over, the patient turns from the middle of the bed to the side of the bed, which makes the patient very unsafe and may even cause the patient to roll off the bed to the ground. In order to prevent this from happening, the nursing staff has to spend a lot of effort to slowly move the patient from the edge to the middle of the bed after the patient turns over. This process is time-consuming and laborious for the nursing staff, and it is also uncomfortable for the patient.

[0005] Therefore, lack a kind of mechanism that can replace manual turning over. Summary of the invention

DETAILED DESCRIPTION

[0055] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0056] according to Figure 1-11 As shown, the embodiment of the present invention provides a semi-automatic auxiliary turning mechanism, comprising: a bed body, a turning mechanism and a translation mechanism,

[0057] The upper surface of the bed body is provided with a turning belt 4 and a translation belt 3, wherein the turning belt 4 is connected to the turning mechanism, and the translation belt 3 is connected to the translation mechanism.

[0058] The turning mechanism and the translation mechanism are both arranged on the lower surface of the bed body;

[0059] The turning mechanism and the translation mechanism are used to drive the turning belt 4 and the translation belt 3 respectively.

[0060] The turning belt 4 and the translation belt 3 are used to turn or move the patient 5 on the bed body.

[0061] The turning belt 4 and the translation belt 3 are provided as one or more belts, and are both provided as flexible cloth or nylon.

[0062] When the auxiliary turning mechanism is working, the turning mechanism and the turning belt 4 can be used to turn the patient 5 on the bed body. At the same time, the translation belt 3 and the translation mechanism can be used to move the patient 5 from one side of the nursing bed to the center of the nursing bed, so that the patient 5 can be in the center of the nursing bed after turning over, thereby reducing the occurrence of bedsores caused by poor blood circulation in the long-term sleeping position of the long-term patient 5 and reducing the discomfort caused by the long-term sleeping position of the patient 5.

[0063] The semi-automatic auxiliary turning mechanism provided by the present invention is suitable for places such as hospital ICU wards, nursing homes and some families with special needs. It is a semi-automatic auxiliary turning mechanism for patients 5 who are unable to turn over, paralyzed in bed or even unconscious, and need manual daily life care. It can be integrated into various types of nursing beds, so that patients 5 who cannot turn over by themselves can turn over very conveniently and easily, reducing the discomfort caused by the patient 5 sleeping in the same position for a long time and the phenomenon of bedsores caused by poor blood flow.

[0064] By using the semi-automatic auxiliary turning mechanism provided by the present invention, the nursing staff can reduce physical strength. As long as they can operate the switches of the turning mechanism and the translation mechanism, they can achieve the purpose of assisting the patient 5 in turning over. This greatly reduces the labor intensity of the nursing staff and makes the patient 5 feel more comfortable when turning over. Since the use of this semi-automatic auxiliary turning mechanism saves time and effort, it also makes it possible for the elderly to take care of the elderly in many families. This turning method also greatly reduces the damage caused to the patient 5 during the process of turning the patient 5 over. In addition, when the patient 5 turns over through the turning mechanism, the translation mechanism translates the patient back to the middle position of the bed, which also greatly reduces the safety hazard of the patient 5 falling out of bed.

[0065] Compared with manual turning over, it improves the work efficiency of nursing staff, reduces the nursing work intensity of nursing staff, avoids the need for nursing staff to manually turn patient 5 when turning patient 5, and avoids the situation where patient 5 needs to be moved from the edge of the nursing bed to the center of the bed after manual turning.

[0066] In one embodiment, the bed body comprises: a bed frame 11, a bed upright 12 and a bed board 2.

[0067] The two ends of the bed frame 11 are respectively provided with bed uprights 12, the upper surface of the bed frame 11 is provided with a bed board 2, a mattress 1 is provided above the bed board 2, the turning belt 4 and the translation belt 3 are provided above the mattress 1, and are provided for the patient 5 to lie down;

[0068] A turning mechanism and a translation mechanism are disposed on the lower surface of the bed frame 11 , and armrests 50 extending upward are disposed on both sides of the bed frame 11 .

[0069] The armrest 50 is provided with a guide wheel 6, and a turning belt 4 is provided above the translation belt 3. The two ends of the turning belt 4 are respectively connected to the turning belt pull rope 7. The turning belt pull rope 7 is respectively located on the left and right sides of the bed when the user is not turning over.

[0070] When turning over, one of the turning-over belt pull ropes 7 passes around the guide wheel 6 and extends to the bottom of the bed frame 11 and is connected to the turning-over mechanism.

[0071] The turning mechanism comprises: a turning motor 10 and a turning belt roller 8,

[0072] Turning belt rollers 8 are symmetrically arranged on both sides below the bed frame 11. The turning belt rollers 8 are used to roll up the turning belt pull rope 7. Both ends of the turning belt rollers 8 are fixed to the bottom of the bed frame 11 through bearing seats 52, and one end of the turning belt rollers 8 is connected to the rotating end of the turning motor 10 through a coupling 9.

[0073] When turning over, one end of the turning belt pull rope 7 away from the turning belt 4 is wound on the turning belt reel 8, and both ends of the axis of the turning belt reel 8 are fixed to the bottom of the bed frame 11 by bearing seats 52, and connected to the turning motor 10 of the turning mechanism through the coupling 9;

[0074] The turning-over belt drawstring 7 on the other side is in a natural state and is not connected to the turning-over mechanism.

[0075] In this embodiment, one end of the turning belt pull rope 7 is fixed to one of the turning belt reels 8 when turning over, and the other end is in a natural state and is not connected to any object; whenever the patient 5 lying on his back on the bed needs to turn over to the right (or left) side, the nursing staff first puts the patient 5 in a position to turn over to the right (left) side according to the nursing specifications, then winds the left (right) turning belt 4 around the upper body of the patient 5, guides the left turning belt pull rope 7 through the right (left) side guide wheel 6 and winds it around the right (left) side turning belt reel 8, and after the preparations are done, press the right (left) turning start button The right (left) turning motor of the turning belt 4 starts to run, so that the turning belt roller 8 is rotated by the coupling 9, and the turning motor 10 tightens the turning belt drawstring 7 when running, and drives the turning belt 4 to be pulled to the right (left), and while the turning belt 4 is pulled to the right (left), the left (right) upper body of the patient 5 is turned to the right (left), until the patient 5 turns to the right (left) side to the ideal state, then the turning stop button can be pressed, the turning motor 10 stops running, the turning belt roller 8 also stops running at the same time, the turning belt 4 stops pulling, and the patient 5 turns to the right (left) end;

[0076] The turning belt 4 is pulled to the right (left) by the turning belt pull rope 7. When the turning belt 4 is pulled to the right, the patient 5 is pulled by the turning belt 4 and changes from the original lying flat position to the right (left) side sleeping position, thereby achieving the purpose of turning the patient 5 from lying flat to the right (left) side.

[0077] In addition, if the turning motor fails again, the turning belt pull rope can also be pulled by manpower / manually to replace the turning mechanism to achieve the purpose of turning.

[0078] In one embodiment, the mattress 1 is symmetrically provided with through holes 51, and the two ends of the translation belt 3 are passed through the holes 51 and are respectively connected to the translation mechanism;

[0079] The translation mechanism includes: a guide roller 15, a retractable roller 16 and a chain 20 transmission mechanism.

[0080] The chain 20 transmission mechanism is mounted below the bed plate 2, and the chain 20 transmission mechanism is respectively connected to two groups of retractable rollers 16, and the circumferential outer wall of the retractable roller 16 is used for winding the translation belt 3;

[0081] Guide rollers 15 are symmetrically mounted on both sides of the bed board 2. The guide rollers 15 are located below the strip holes 51. The circumferential outer walls of the guide rollers 15 are in contact with the translation belt 3 and are used to guide the translation belt 3 passing through the strip holes 51 to the bottom of the mattress 1.

[0082] The retractable roller 16 is connected to the lower surface of the bed board 2 via a retractable roller bearing seat 17 .

[0083] The chain 20 transmission mechanism includes: a translation motor 18, a chain 20 and a driving sprocket 21.

[0084] The rotating end of the translation motor 18 is connected to the driving sprocket 21, and the translation motor 18 is located at the center of the bed board 2;

[0085] Driven sprockets 19 are respectively provided on both sides of the bed board 2 , and each of the driven sprockets 19 is fixedly connected to the retracting roller 16 via a rotating shaft. The driving sprocket 21 and the two driven sprockets 19 are linked and connected via a chain 20 .

[0086] The translation motor 18 is provided with a motor seat 22, and the motor seat 22 is mounted on the lower surface of the bed board 2 via a motor bracket 23;

[0087] A chain cover 25 is provided below the bed board 2 , and the chain cover 25 is used to cover the driving sprocket 21 , the driven sprocket 19 and the chain 20 .

[0088] The translation belt 3 is a rectangular structure. The translation belt 3 first passes through the strip holes 51 on the mattress 1 and extends to both sides of the bed board 2. The two ends of the translation belt 3 are respectively fixed and wound on the retracting roller 16, and are stretched by the guide roller 15 and the retracting roller 16.

[0089] In this embodiment, in order to prevent the patient 5 from falling due to being at the edge of the nursing bed when turning over, a translation mechanism is designed to pull the patient 5 back to the center of the bed by a translation belt while the patient 5 is turning over, thereby reducing the possibility of the patient 5 falling.

[0090] When working, the translation motor 18 is started, and the translation motor 18 drives the driving sprocket 21 to rotate through the first rotating shaft 24, so that the driven sprockets 19 on both sides are driven to rotate through the chain 20, and the retracting roller 16 connected to the driven sprocket 19 will rotate; when the retracting roller 16 rotates, the translation belt 3 wound on the retracting roller 16 will be retracted and released on the retracting roller 16; specifically, according to Figure 1-4As shown, the chain 20 transmission mechanism drives the left (right) side retracting roller 16 to rotate counterclockwise (from the direction of the patient 5's head), tightens the translation belt 3, and moves the translation belt 3 to the left (right). The right (left) side retracting roller 16 also rotates counterclockwise, just releasing the translation belt 3. In this way, under the action of the left and right retracting rollers 16, the right (left) side is released and the left (right) side is retracted, so that the translation belt 3 moves to the left (right). Since the patient 5 is lying on the translation belt 3, the translation belt 3 drives the patient 5 body to move to the left (right) back to the middle position of the bed by friction.

[0091] If the translation belt 3 does not move to the left (right) side, the patient 5 will move to the right (left) side edge of the bed after turning to the right (left). Now, with the translation belt 3, the patient 5 will move to the left (right) side while turning to the right (left), so that the patient 5 returns to the middle position of the bed after turning, thereby ensuring the safety and comfort of the patient 5.

[0092] When the patient 5 turns over to the right (left), the patient 5 also moves to the left (right) driven by the translation belt 3. When the turning over is completed, the patient 5 also returns to the middle position of the bed. In this way, the patient 5 will not sleep on the right (left) edge of the bed due to turning over to the right (left). This avoids the situation where the patient 5 is no longer in the middle of the bed after turning over due to other turning over methods, thereby eliminating the safety hazard of the patient 5.

[0093] In one embodiment, according to Figure 6-10 As shown, an isolation mechanism is further provided below the bed body, and the isolation mechanism is located below the bed frame 11.
