Description

TECHNICAL FIELD

[0001] The utility model relates to the field of medical apparatus and instruments, and particularly relates to a medical turning-over device. BACKGROUND

[0002] If a coma patient keeps a body position for a long time, the same part of the body is in contact with the bed and is pressed for a long time, and pressure sores are prone to occur. Therefore, the body position needs to be adjusted once in a period of time, and general regulations are to adjust once every two hours. The body position is generally adjusted by alternating between lying flat and lying on one's side, and the body position adjustment is clinically referred to as turning over. The coma patient cannot keep lying on one's side by himself, and therefore a turning-over pillow is used to assist in lying on one's side. The common turning-over pillow is actually a triangular supporting tool, and the patient can keep lying on one's side by leaning on the turning-over pillow on the back.

[0003] Some turning-over pillows are improved on the basis of the traditional fixed-angle turning-over pillow, and the turning-over pillow is provided with an angle-adjustable function. In this way, the angle of the patient's lying on one's side can be adjusted. Secondly, it is very laborious to manually turn over the coma patient, and female nurses are not easy to complete the task. After the angle of the turning-over pillow is adjusted to be small, the turning-over pillow is placed under the patient, and the turning-over pillow is lifted by the angle-adjusting structure, so that the patient is lifted from lying flat to lying on one's side, and the patient can be turned over labor-savingly.

[0004] ZL201821362075.4 discloses a turning-over pillow with an adjustable angle, and the turning-over pillow is lifted by a gas cylinder. ZL201820686058.X discloses a turning-over pillow, and the turning-over pillow is lifted by a screw nut mechanism driving a supporting rod. The two kinds of turning-over pillows can adjust the angle of the turning-over pillow labor-savingly when the patient lies on them.

[0005] However, the above-mentioned turning-over pillows also have some shortcomings. Firstly, the cost is high due to the self-contained angle-adjusting mechanism. Secondly, the angle-adjusting mechanism has a high height, and the angle of the turning-over pillow is difficult to adjust to be very small. Therefore, the patient still needs to be turned over manually to a large angle, and then the turning-over pillow can be placed under the patient, and the labor-saving effect is limited. UTILITY MODEL CONTENTS

[0006] The technical problem to be solved by the utility model is to provide a medical turning-over device with an angle that can be adjusted labor-savingly and adjusted to be flat.

[0007] The technical scheme adopted to solve the above problems is: the medical turning-over device comprises a turning-over pillow and a turning-over pillow driver; the turning-over pillow comprises a bottom plate, an upper plate, a support and a hanging ring, one side of the upper plate is hingedly connected with one side of the bottom plate to form an openable and closable turning-over pillow main body, when the turning-over pillow main body is opened, the support can support the upper plate to avoid the turning-over pillow main body from being closed, and the hanging ring is connected with the middle part of the movable side of the upper plate; the turning-over pillow driver comprises a base, a roller, a lifting mechanism and a cross beam, the roller is located below the base and connected with the base, the lifting mechanism is located above the base and connected with the base, the cross beam is connected with the lifting mechanism, and the end part of the cross beam is provided with a hook; when the turning-over pillow driver is used, the hook is hooked on the hanging ring, and the lifting mechanism can drive the upper plate to rotate with less labor.

[0009] Further, the operating structure is a handle.

[0010] Further, the operating structure comprises an operating rod and a swing connecting rod, the middle part of the operating rod is hingedly connected with the inflation cylinder piston rod, one end of the swing connecting rod is hingedly connected with the base, and the other end of the swing connecting rod is hingedly connected with one end of the operating rod.

[0011] Further, the bottom plate is provided with a plurality of positioning protrusions, the positioning protrusions are arranged at intervals in the direction from the movable side to the hinged side of the bottom plate, and the support is hingedly connected with the upper plate; when the support supports the upper plate, the lower end of the support abuts on the positioning protrusions, and the positioning protrusions limit the movement of the lower end of the support.

[0012] Further, the upper plate comprises a hard plate and a flexible pad connected to the hard plate.

[0013] Further, the hanging ring is made of a flexible material.

[0014] Further, the upper plate is provided with a medicine applying window, the medicine applying window can be opened backward, and the medicine applying window corresponds to the sacrococcygeal position of a patient when the patient leans on the turning-over pillow.

[0015] The beneficial effects of this utility model are: 1. This utility model uses a turning pillow driver to drive the upper panel of the turning pillow to swing. Specifically, as follows... Figure 1 As shown, the turning pillow is placed on the hospital bed like a regular turning pillow. When the angle of the turning pillow needs to be adjusted, push the turning pillow driver to the side of the bed so that the hook engages with the hanging ring. Then operate the lifting mechanism, which drives the hook to rise and fall, thus rotating the upper panel and adjusting the angle of the turning pillow. After the angle is adjusted, use the bracket to support the upper panel to maintain the angle. In this way, the turning pillow angle can be adjusted effortlessly even when the patient is lying or leaning on the turning pillow. Since a patient is usually turned over only once every two hours, the turning pillow driver can be removed after use to drive the turning pillows of other patients. This utility model is suitable for equipping one turning pillow driver in one ward of a hospital, which can basically achieve effortless adjustment of the turning pillow angle for all patients in that ward.

[0016] 2. Compared with the existing adjustable-angle turning pillows described in the background art, firstly, the turning pillow of this utility model does not have an angle adjustment mechanism, such as... Figure 4 As shown, the turning pillow can be adjusted to a flat shape, making it easy to place under the patient's body. The patient can even lie on the turning pillow while lying flat, eliminating the need to place the pillow under them. Therefore, this invention provides more effortless assistance for patients turning over. Secondly, although this invention includes multiple turning pillow drivers, one driver can be used with several turning pillows. Furthermore, the structure of the turning pillow itself is significantly simpler than existing adjustable-angle turning pillows, resulting in a significant reduction in cost. Overall, the actual cost is lower than that of existing adjustable-angle turning pillows. Attached Figure Description

DETAILED DESCRIPTION

[0024] The utility model is further illustrated below in combination with the drawings and specific embodiments.

[0025] As Figures 1 to 6 shown, the medical turning-over device includes the turning-over pillow 1 and the turning-over pillow driver 2;The turning-over pillow 1 includes the bottom plate 11, the upper panel 12, the support 13 and the hanging ring 14, and one side of the upper panel 12 is hinged with one side of the bottom plate 11 to form the openable and closeable turning-over pillow body, when the turning-over pillow body is opened, the support 13 can support the upper panel 12 to avoid the turning-over pillow body closing, and the hanging ring 14 is connected with the middle part of the movable side of the upper panel 12;The turning-over pillow driver 2 includes the base 21, the roller 22, the lifting mechanism 23 and the crossbeam 24, the roller 22 is located below the base 21 and is connected with the base 21, the lifting mechanism 23 is located above the base 21 and is connected with the base 21, the crossbeam 24 is connected with the lifting mechanism 23, and the end of the crossbeam 24 is provided with the hook 241;When the turning-over pillow driver 2 is used, the hook 241 is hooked on the hanging ring 14, and the lifting mechanism 23 can drive the upper panel 12 to rotate labor-savingly.

[0026] The utility model adopts the turning-over pillow driver 2 to drive the upper panel 12 of the turning-over pillow 1 to swing. Figure 1As shown, the turning-over pillow 1 is placed on the sickbed 3 for use as a common turning-over pillow, when the angle of the turning-over pillow 1 needs to be adjusted, the turning-over pillow driver 2 is pushed to the side of the sickbed 3, so that the hook 241 hooks the hanging ring 14. Then the lifting mechanism 23 is operated, the lifting mechanism 23 drives the hook 241 to lift and also drives the upper panel 12 to rotate, so that the angle adjustment of the turning-over pillow 1 is realized. After the angle adjustment, the bracket 13 is used to support the upper panel 12 to maintain the angle. In this way, the angle of the turning-over pillow 1 can be adjusted labor-savingly even if the patient lies or leans on the turning-over pillow 1. Since a patient usually turns over once every two hours, after the turning-over pillow driver 2 is used, it can be withdrawn to drive the turning-over pillow 1 of other patients. The utility model is suitable for a sick ward of a hospital to be equipped with one turning-over pillow driver 2, and basically the angle adjustment of the turning-over pillow 1 of all patients in the sick ward can be realized labor-savingly. It should be noted that since the upper panel 12 swings instead of moving up and down, during the angle adjustment of the turning-over pillow 1, the turning-over pillow driver 2 should be slowly pushed forward; during the angle reduction of the turning-over pillow 1, the turning-over pillow driver 2 should be slowly pulled backward.

[0027] Compared with the existing angle-adjustable turning-over pillow described in the background art, first, the turning-over pillow 1 of the utility model does not itself set an angle adjustment mechanism, like Figure 4 As shown, the turning-over pillow 1 can be adjusted to be flat, so as to be placed under the patient's body, and the patient can even lie on the turning-over pillow 1 when lying flat, so that the operation of placing the turning-over pillow 1 under the patient's body is saved. Therefore, the utility model can more labor-savingly assist the patient to turn over. Second, although the utility model is usually equipped with a turning-over pillow driver 2, one turning-over pillow driver 2 can be used in cooperation with several turning-over pillows 1, and the structure of the turning-over pillow 1 of the utility model itself is obviously simpler than that of the existing angle-adjustable turning-over pillow, and the cost of the turning-over pillow 1 itself is obviously reduced. In summary, the actual cost is lower than that of the existing angle-adjustable turning-over pillow.

[0028] The lifting mechanism 23 is specifically as Figure 2 and Figure 3As shown, the lifting mechanism 23 comprises a lifting cylinder 231 and a charging cylinder 232, both of which are vertically arranged and connected with the base 21; the charging cylinder 232 comprises a charging cylinder cylinder 2321, a charging cylinder piston 2322, a charging cylinder piston rod 2323, a first one-way valve 2324, a second one-way valve 2327 and a discharging valve 2325, the charging cylinder piston 2322 is located in the charging cylinder cylinder 2321 and cooperates with the charging cylinder cylinder 2321, the inner cavity of the charging cylinder cylinder 2321 below the charging cylinder piston 2322 is a charging cavity 2326, the first one-way valve 2324 is installed on the charging cylinder piston 2322 and can be opened in one direction to the charging cavity 2326, the second one-way valve 2327 is installed on the charging cylinder cylinder 2321 and corresponds to the charging cavity 2326, the second one-way valve 2327 can be opened in one direction to the outside of the charging cavity 2326, the discharging valve 2325 is installed on the charging cylinder cylinder 2321 and communicates with the lifting cylinder 231; the charging cylinder piston rod 2323 extends into the charging cylinder cylinder 2321 from top to bottom and is connected with the charging cylinder piston 2322; the second one-way valve 2327 is connected with the lifting cylinder 231, the cross-sectional area of the charging cavity 2326 is smaller than that of the inner cavity of the lifting cylinder 231; the operating structure 233 is connected with the charging cylinder piston rod 2323. The specific structure of the above lifting mechanism 23 is similar to the existing pneumatic jack design.

[0029] The working principle of the lifting mechanism 23 is also similar to that of the pneumatic jack. Pulling up the operating structure 233, the charging cylinder piston rod 2323 moves upward, the second one-way valve 2327 is closed, the first one-way valve 2324 is opened, and the charging cavity 2326 inhales. Pressing down the operating structure 233, the charging cylinder piston rod 2323 moves downward, the first one-way valve 2324 is closed, the second one-way valve 2327 is opened, the gas in the charging cavity 2326 is pressed into the lifting cylinder 231, the lifting cylinder 231 is elongated, and the upper panel 12 can be driven to swing upward. Opening the discharging valve 2325, the discharging valve 2325 discharges, and the lifting mechanism 23 shortens, and the upper panel 12 swings downward. Because the cross-sectional area of the charging cavity 2326 is smaller than that of the inner cavity of the lifting cylinder 231, the lifting mechanism 23 can drive the upper panel 12 to rotate with less effort. The cross-sectional area of the charging cavity 2326 is preferably not greater than 1 / 5 of the cross-sectional area of the inner cavity of the cylinder 231, so that the effort-saving effect is better.

[0030] The operating structure 233 is only a handle. However, in order to save more effort, the operating structure 233 preferably comprises an operating rod 2331 and a swing connecting rod 2332, the middle part of the operating rod 2331 is hinged with the charging cylinder piston rod 2323, one end of the swing connecting rod 2332 is hinged with the base 21, and the other end of the swing connecting rod 2332 is hinged with one end of the operating rod 2331.

[0031] The structure 233 is a force-saving lever, and can further save force.

[0032] The specific structure of the support 13 supporting the upper panel 12 is as follows: the bottom plate 11 has a plurality of positioning protrusions 111, and the positioning protrusions 111 are arranged at intervals in the direction from the movable side to the hinged side of the bottom plate 11, and the support 13 is hinged to the upper panel 12; when the support 13 supports the upper panel 12, the lower end of the support 13 abuts against the positioning protrusion 111, and the positioning protrusion 111 limits the movement of the lower end of the support 13; thus, when the lower end of the support 13 abuts against different positioning protrusions 111, the angle of the turning-over pillow 1 is different. Figure 4 As shown, the support 13 is manually placed flat, and the turning-over pillow 1 can be completely closed to be flat.

[0033] Since the patient needs to lean against the upper panel 12, the surface of the upper panel 12 should be soft, and specifically, the upper panel 12 includes a hard plate 121 and a flexible pad 122 connected to the hard plate 121.

[0034] The hanging ring 14 is preferably made of flexible material, for example, cloth, so as to avoid the patient from being uncomfortable or even injured by touching the hanging ring 14.

[0035] Further, the upper panel 12 preferably has a medicine application window 123, and the medicine application window 123 can be opened backward; when the patient leans against the turning-over pillow 1, the medicine application window 123 corresponds to the sacrococcygeal position of the patient. The significance of such a setting is that the sacrococcygeal position is one of the positions with the highest risk of pressure sores of the skin of the patient lying in bed, and since it is located at the back of the body, it is inconvenient to treat and apply medicine when a pressure sore occurs. Thus, the medicine application window 123 can be opened, and the sacrococcygeal position can be treated and applied with medicine from the back side of the upper panel 12, without the patient changing the body position for medicine application. In addition, if a pressure sore occurs in the sacrococcygeal position, the medicine application window 123 can also be kept open to avoid the sacrococcygeal position being continuously pressed. The medicine application window 123 can be hinged to the rest of the upper panel 12 on one side and connected to the rest of the upper panel 12 on the other side by using the existing buckle structure.
