Description

Technical Field

[0001] The invention belongs to the technical field of medical cold compress nursing devices, and in particular relates to a circulating cold compress physiotherapy device for orthopedic post-operative nursing. Background Art

[0002] The working principle of the cold compress machine is mainly to quickly transfer low temperature to the part that needs cold compress through the coolant circulation system. This process is based on the cooling cycle. The coolant absorbs heat through the process of compression and expansion inside the machine, and then transfers the low temperature to the cold compress pad through the catheter to achieve a local cooling effect on the human body. The cold compress machine uses low temperature to constrict blood vessels, reduce activity and reduce nerve conduction speed, thereby achieving the effect of reducing pain and swelling. The device provides a stable cooling effect by precisely controlling the cold compress temperature so that the therapeutic effect can be achieved without damaging the skin and tissue.

[0003] The cooling structure of the cold compress machine usually relies on semiconductor cooling technology, which uses the Peltier effect to generate heat absorption and heat release by passing direct current between N-type and P-type semiconductor materials, thereby achieving cooling. This cooling method has the characteristics of small size, low noise, maintenance-free, environmental protection and safety.

[0004] After orthopedic surgery, a cold compress machine is needed to assist in recovery treatment. However, cold compress machines generally only perform cold compress treatments, with relatively simple functionality and no corresponding massage activity adjustments, which makes it difficult for local blood stasis to disperse, and is not conducive to improving human health. In addition, when performing cold compress treatments on human legs, the legs need to be kept in a relatively horizontal state to assist in the cold compress treatment, and there is no support mechanism with adaptive length adjustment, which makes cold compress therapy inconvenient. Summary of the invention

DETAILED DESCRIPTION

[0034] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] Reference Manual Attached Figure 1 and Figure 2 As shown, a circulating cold compress physiotherapy device for orthopedic postoperative care includes:

[0036] A bottom plate 1, a mobile frame 2 is fixedly installed around the bottom plate 1 through a bracket, a roller adapted thereto is installed on the mobile frame 2, and a support adjustment mechanism 3, the support adjustment mechanism 3 includes a cover body fixed on the bottom plate 1, a first motor 4 is installed on one side of the inner wall of the cover body, the output shaft of the first motor 4 extends to the driving wheel 5 and the first reciprocating screw 6 in sequence, both ends of the first reciprocating screw 6 are spirally driven with a Y-axis telescopic rod 7 that moves in the opposite direction, the Y-axis telescopic rod 7 is connected with a strip groove 8 along the length direction of the bottom plate 1, and the top of the Y-axis telescopic rod 7 is connected with a support portion 10 through a first spring rod 9, and the support portion 10 is arranged in an arc shape;

[0037] Among them, the driving wheel 5 and the driven wheel 11 are connected through the first conveyor belt 12, the outer wall of the first bevel gear 13 at one end of the driven wheel 11 is meshed with the second bevel gear 15 fixed on the second reciprocating screw 14, the second reciprocating screw 14 and the driven wheel 11 are kept vertically arranged, and the second reciprocating screw 14 is spirally driven with a slider 16, and the slider 16 is fixedly connected to the Y-axis telescopic rod 7 at both ends through the X-axis telescopic rod 17.

[0038] A support adjustment mechanism 3 is provided. After the first motor 4 is started, it can drive the rotation of the driving wheel 5 and the first reciprocating screw 6. With the help of the spiral transmission, the support part 10 on the first spring rod 9 can be moved in the opposite direction, thereby playing a role in adjusting the spacing. At the same time, the driving wheel 5 can drive the rotation of the driven wheel 11. Under the action of mechanical transmission, it can drive the rotation of the second reciprocating screw 14 in the vertical direction, thereby making the slider 16 drive the support part 10 to move up and down. The first spring rod 9 is provided with an X-axis telescopic rod 17 and a Y-axis telescopic rod 7. The purpose is to allow the support part 10 to perform normal up and down and horizontal movements at the same time to avoid interference between the transmission parts. At the same time, when the spacing of the support part 10 becomes larger, the height also increases, which can adapt to the skeleton sizes of different human bodies, can effectively play a supporting effect, and is beneficial to the subsequent cold compress treatment work.

[0039] Specifically, the setting of the Y-axis telescopic rod 7 allows the support part 10 to move up and down normally, while the setting of the X-axis telescopic rod 17 is to allow the support part 10 to move horizontally normally. Since the horizontal movement and the up and down movement of the support part 10 are carried out simultaneously, in order not to affect the interference movement of the transmission parts, the X-axis telescopic rod 17 and the Y-axis telescopic rod 7 are provided. When the human body is sitting, the skeleton length is longer, which also means that the sitting height will become higher. Therefore, when the support part 10 moves in the reverse direction and the spacing is enlarged, the second reciprocating screw 14 drives the Y-axis telescopic rod 7 to move upward through the slider 16. When moving in the reverse direction, the X-axis telescopic rod 17 can allow the support part 10 to move horizontally normally. At the same time, when moving upward, the Y-axis telescopic rod 7 can allow the support part 10 to move vertically normally. Conversely, when the support part 10 moves in the reverse direction and the spacing is reduced, the second reciprocating screw 14 drives the Y-axis telescopic rod 7 to move downward through the slider 16.

[0040] In addition, the support portion 10 is arranged in an arc shape, which can expand the contact area with the skeleton so that the force can be dispersed, which can make the patient have good comfort. A first spring rod 9 is also arranged on the support portion 10, which can improve the buffering performance of the device and facilitate increasing the service life of the device.

[0041] refer to Figure 1 , Figure 6 , Figure 7 and Figure 8, the contact cold compress mechanism 18 includes a frame installed on the base plate 1, and movable plates 20 are installed on both ends of the frame through electric lifting rods 19. The movable plate 20 is provided with a semiconductor refrigeration plate 21 connected to the power supply, and one end of the semiconductor refrigeration plate 21 is connected to the silicone pad 22 by heat conduction. The contact cold compress mechanism 18 is used to realize cyclic pressing cold compress work on the outer surface of the bone.

[0042] A panel 23 is installed at the bottom end of the movable plate 20 through a column, and a second motor 24 is fixedly installed at the center of the movable plate 20. The output shaft of the second motor 24 passes through the shell and extends to the third bevel gear 25 and the rotating rod 26 in sequence. The outer wall edge of the rotating rod 26 is connected to an annular groove 27 placed on the panel 23 near the silicone pad 22, and a roller 29 is installed at the bottom of the rotating rod 26 through a telescopic cylinder 28. The outer wall of the roller 29 is rotatably connected to the first massage ball head 30. As the second motor 24 is started, the rotating rod 26 drives the first massage ball head 30 to rotate and circulate massage on the outer surface of the bone body.

[0043] A contact cold compress mechanism 18 is provided, and an electric lifting rod 19 lowers the cold compress mechanism to a corresponding height of the frame. Under the effect of semiconductor refrigeration technology, the cooled silicone pad 22 is brought into contact with the frame, and the heat of the human body is absorbed by continuous cooling, thereby achieving a cold compress effect. At the same time, the second motor 24 is started, and the rotating rod 26 drives the first massage ball head 30 on the roller 29 to perform friction and rotation massage on the surface of the frame. In addition, a telescopic cylinder 28 is provided on the rotating rod 26, and the massage height of different high and low surfaces on the frame can be adjusted. The second motor 24 can drive the rotation of the third bevel gear 25. The gear meshing transmission drives the cam 32 to rotate, and then converts the circular motion of the cam 32 into the up and down movement of the second massage ball head 36, which can help massage activities by pressing, thereby accelerating blood circulation and improving the treatment effect. In addition, the third bevel gear 25 can drive the first rotating wheel 38 to rotate, and then drive the blades 41 on the rotating shaft 42 to rotate, thereby playing a corresponding cooling and regulating role, further improving the cold compress treatment effect. The design of the present invention has strong integrated performance, good circulating cold compress performance, auxiliary massage function, and better comprehensive treatment effect.

[0044] Both ends of the outer wall of the third bevel gear 25 are meshed and transmitted with a fourth bevel gear 31 fixed on the first rotating shaft, a cam 32 is fixedly installed at one end of the first rotating shaft, the bottom of the cam 32 is in contact with a contact plate 34 fixed on the second spring rod 33, and the bottom of the second spring rod 33 passes through the panel 23 and extends to the arc plate 35, and a second massage ball head 36 is fixedly installed at the bottom of the arc plate 35. As the second motor 24 is started, the second spring rod 33 drives the second massage ball head 36 to press up and down, and one side of the outer wall of the third bevel gear 25 is meshed and transmitted with a fifth bevel gear 37 located between the fourth bevel gear 31, and one end of the fifth bevel gear 37 is connected to a first rotating wheel 38 placed on the outer wall of the frame through the second rotating shaft, and the first rotating wheel 38 and the second rotating wheel 39 are connected through a second conveyor belt 40 for transmission, and the extension of the second rotating wheel 39 is connected to a rotating shaft 42 fixed on the blade 41.

[0045] Specifically, the first massage ball head 30 and the second massage ball head 36 are linkage mechanisms, that is, the two perform massage movements at the same time. When the second motor 24 is started, it can drive the roller 29 on the rotating rod 26 to perform circular friction massage on the surface of the skeleton. The annular groove 27 on the panel 23 provides a corresponding activity space for the circular motion of the rotating rod 26. By extension, a roller connected to the rotating rod 26 can be adaptively provided in the annular groove 27. The rotating rod 26 is rotated by rolling friction, which can effectively reduce friction and reduce friction damage, thereby increasing the service life of the device.

[0046] In addition, when the second motor 24 is started, it can drive the cam 32 to rotate through the transmission member. Since the cam 32 is in contact with the contact plate 34 on the second spring rod 33, it can drive the second spring rod 33 to move up and down, thereby allowing the second massage ball head 36 on the arc plate 35 to push up and down for massage. The arc plate 35 can be set to a semicircular shape, so that the overall massage work can be achieved on the outer surface of the skeleton. The arc plate 35 and the second spring rod 33 can also be connected by a telescopic component, so that they can adapt to different heights on the skeleton. The above-mentioned telescopic component is a conventional technical means for those skilled in the art, and will not be described in detail here, so there is no corresponding drawing, but it does not affect the effective implementation of the technical solution of the present invention.

[0047] Specifically, a rotating groove is provided on one side of the first rotating wheel 38 and the second rotating wheel 39 on the outer wall of the frame, and the rotating groove is connected to the first rotating wheel 38 and the second rotating wheel 39 through bearings. The blades 41 are connected to the rotating shaft 42 by plugging, and the blades 41 are distributed on the rotating shaft 42 in a circular array. When the second motor 24 is started, the rotating shaft 42 drives the blades 41 to cool down and dissipate heat on the surface of the bone body.

[0048] After the second motor 24 is started, it can drive the fifth bevel gear 37 to rotate through the third bevel gear 25, and then drive the first rotating wheel 38 to rotate. Through the transmission action of the second conveyor belt 40, the blades 41 on the second rotating wheel 39 rotate to dissipate heat, thereby further improving the cooling effect and enhancing the structural integration performance of the entire device.

[0049] refer to Figure 1 , Figure 4 and Figure 5 A threaded groove is provided at the bottom of the support part 10 and is connected to the first spring rod 9 by a threaded connection. The support part 10 is symmetrically arranged relative to the center of the base plate 1. An active cavity connected to the first reciprocating screw 6 and the second reciprocating screw 14 is provided in the cover body. A positioning hole is provided at the connection between the first motor 4 and the cover body and is connected by locking and fixing with a stop pin.

[0050] A accommodating cavity is formed between the base plate 1 and the movable frame 2, so that corresponding storage space can be provided for the transmission parts in the cover body. At the same time, the strip groove 8 on the base plate 1 also provides a movable space for the movement of the first spring rod 9, thereby preventing the support part 10 from deviating from its position during the horizontal movement. In addition, when the first motor 4 is started, it can simultaneously drive the rotation of the first reciprocating screw 6 and the second reciprocating screw 14. With the help of the spiral transmission, the support part 10 can move up and down and horizontally at the same time, and the transmission parts work stably, and can adaptively support and adjust the skeletons of different lengths.

[0051] A mobile frame 2 is arranged on the bottom plate 1, and the device can be moved to a corresponding position indication point and fixed thereon, thereby providing convenience for patients with limited mobility, and also facilitating the placement of corresponding medical equipment, providing a certain storage space therefor, and improving the applicability of the device.

[0052] The semiconductor refrigeration technology uses a PN junction composed of special semiconductor materials to form a thermocouple pair, and produces a cooling effect through direct current. The semiconductor refrigeration sheet 21 is composed of a P-type semiconductor and an N-type semiconductor.
