Technical Field
[0001] The invention relates to the field of medical device technology, specifically to an orthopedic circulating cold compress device. Background Technology
[0002] Orthopedic patients need to apply cold compresses to control bleeding from small blood vessels and reduce pain from tense lumps. Applying ice packs or cold, damp towels to the affected area can promote local vasoconstriction, thereby reducing swelling and pain, reducing local blood flow, and preventing the spread of inflammation and suppuration. However, current cold compress devices still have some problems.
[0003] When outdoors, the duration of the ice pack is relatively short, and it is not possible to continuously reduce swelling in the patient's swollen area. Summary of the Invention
[0004] To address the shortcomings of existing technologies, this invention provides an orthopedic circulating cold compress device that solves the problem that outdoor ice compress devices have a short duration of action and cannot continuously reduce swelling in patients' swollen areas.
[0005] An orthopedic circulating cold compress device includes a main body box and a cold compress device, wherein the cold compress device is detachably connected to the main body box, and the main body box has through holes on both sides and is hinged with baffles. The cold compress device includes: a fixing clip, a first cold compress bag, and a second cold compress bag. The first cold compress bag is detachably connected to the bottom of the main body box. The fixing clip is fixedly connected to the first cold compress bag. The second cold compress bag is fixedly connected to the inside of the fixing clip. A first drainage tube is connected between the first cold compress bag and the second cold compress bag.
[0006] Furthermore, it also includes: a storage bag connected to the outside of the first cold compress bag, a second drainage tube connected between the first cold compress bag and the storage bag, a cooling bag connected to the outside of the storage bag, a third drainage tube connected between the cooling bag and the storage bag, and a fourth drainage tube connected between the second cold compress bag and the cooling bag.
[0007] Furthermore, it also includes: the first cold compress bag is made of rigid material, a first sliding plate is slidably connected inside the first cold compress bag, a first push rod is connected to one side of the first sliding plate, and both the first cold compress bag and the first push rod are arc-shaped.
[0008] Furthermore, a first magnetic block is connected to the bottom of the main box, and a second magnetic block corresponding to the first magnetic block is connected to the outside of the first cold compress bag.
[0009] Furthermore, the first, second, third, and fourth drainage tubes are all connected to one-way valves.
[0010] Furthermore, the storage bag is made of rigid material and a second sliding plate is slidably connected inside the storage bag. The second sliding plate is connected to a second push rod, and a one-way valve is connected to one side of the second push rod.
[0011] Furthermore, the inner side of the fixing clamp is connected to a sliding groove, a stop plate is slidably connected in the sliding groove, and a screw is rotatably connected to one end of the stop plate, the screw being threadedly connected to the sliding groove.
[0012] Furthermore, a first cooling chip is connected inside the main body box.
[0013] Furthermore, the storage bag has a cavity on the side near the second push rod.
[0014] Furthermore, a second cooling element is connected inside the cooling bag, and a storage battery is connected to the outside of the cooling bag. The storage battery is electrically connected to the second cooling element. The two sides of the cooling bag are made of rigid material, and the middle part of the cooling bag is made of flexible material.
[0015] As can be seen from the above technical solution, the invention provides an orthopedic circulating cold compress device, which allows the injured area of the patient to be cooled down by the cold compress device to prevent swelling; after the injured area of the patient is cooled down by the second cold compress bag, the refrigerant heated in the second cold compress bag is discharged into the storage bag, and then the refrigerant in the first cold compress bag is added into the second cold compress bag so as to continuously cool the patient. After cooling the injured area of the patient with the second cold compress, the refrigerant that has heated up in the second cold compress is discharged into the cold compress to continue cooling the coolant, so that it can be cooled multiple times. Then the refrigerant in the first cold compress is added into the second cold compress to continuously cool the patient. The coolant is added to the first cold compress bag through the storage bag, so that the coolant can be replaced after the second cold compress bag has been used multiple times to continue applying cold compresses to the injured area. This greatly extends the duration of the cold compress, allowing patients to apply cold compresses to the injured area for an extended period of time, even when outdoors. Attached Figure Description

Detailed Implementation
[0019] The embodiments of the invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the invention and should not be construed as limiting the scope of protection of the invention.
[0020] like Figure 1-3 As shown in the figure, this embodiment provides an orthopedic circulating cold compress device, including: a main body box 1 and a cold compress device 4. The cold compress device 4 is detachably connected to the main body box 1, so that the patient can remove the cold compress device 4 after fixing the injured area to the cold compress device 4. The main body box 1 has through holes 2 on both sides and is hinged with baffles 3, which facilitates the patient to place the injured area on the cold compress device 4; a first magnetic block 5 is connected to the bottom of the main body box 1, and a second magnetic block 6 corresponding to the first magnetic block 5 is connected to the outside of the first cold compress bag 42, thereby fixing the cold compress device 4 inside the main body box 1.
[0021] The cold compress device 4 includes: a fixing clip 41, a first cold compress bag 42, and a second cold compress bag 43. The first cold compress bag 42 is detachably connected to the bottom of the main body box 1, and the fixing clip 41 is fixedly connected to the first cold compress bag 42, used to fix it to the injured area. The second cold compress bag 43 is fixedly connected to the inside of the fixing clip 41, used to apply cold compresses to the injured area. A first drainage tube 44 is connected between the first cold compress bag 42 and the second cold compress bag 43, and a one-way valve 7 is connected thereto, allowing the coolant in the first cold compress bag 42 to be added into the second cold compress bag 43.
[0022] The first cold compress bag 42 is made of rigid material, and a first sliding plate 46 is slidably connected inside the first cold compress bag 42. A first push rod 47 is connected to one side of the first sliding plate 46. Both the first cold compress bag 42 and the first push rod 47 are arc-shaped. The first push rod 47 drives the first sliding plate 46 to move, thereby squeezing the coolant in the first cold compress bag 42 into the second cold compress bag 43.
[0023] The inner side of the fixing clip 41 is connected to a sliding groove 9, and a support plate 10 is slidably connected within the sliding groove 9. The support plate 10 moves to contact the limb, thereby raising the second cold compress bag 43 and increasing the gap between the limb and the second cold compress bag 43. A screw 8 is rotatably connected to one end of the support plate 10, and the screw 8 is threadedly connected to the sliding groove 9. A cooling element 11 is connected inside the main body box 1 to cool the interior of the main body box 1.
[0024] The working principle of the above scheme is as follows: When it is necessary to cool and reduce swelling of the injured area, the main body box 1 is opened, and the injured area is placed between the second cold compress bags 43. At this time, the baffle 3 is flipped to close the fixing clip 41, so that the second cold compress bags 43 are close to the injured area. After the coolant in the second cold compress bags 43 heats up, the coolant in the second cold compress bags 43 is drained. At this time, the first push rod 47 is pushed to move the first slide plate 46, squeezing the coolant in the first cold compress bag 42 into the first drainage tube 44. The coolant enters the second cold compress bag 43 through the first drainage tube 44 to apply a cold compress to the patient, increasing the cold compress time.
[0025] The beneficial effects of the above scheme are as follows: the cold compress device 4 can cool down the injured area of the patient and prevent swelling; after the injured area of the patient is cooled down by the second cold compress bag 43, the refrigerant that has been heated in the second cold compress bag 43 is discharged, and then the refrigerant in the first cold compress bag 42 is added to the second cold compress bag 43 so that the patient can be continuously cooled down.
[0026] In one embodiment of the present invention, such as Figures 1-4 As shown, a storage bag 48 is connected to the outside of the first cold compress bag 42. A second drainage tube 45 connects the first cold compress bag 42 and the storage bag 48. A cooling bag 412 for cooling the coolant is connected to the outside of the storage bag 48. A third drainage tube 49 connects the cooling bag 412 and the storage bag 48, allowing the coolant in the cooling bag 412 to enter the storage bag 48 through the third drainage tube 49. A fourth drainage tube 413 connects the second cold compress bag 43 and the cooling bag 412. One-way valves 7 are connected to the first drainage tube 44, the second drainage tube 45, and the third drainage tube 49. The storage bag 48 is made of rigid material, and a second sliding plate 410 is slidably connected inside the storage bag 48. A second push rod 411 is connected to the second sliding plate 410, and a one-way valve 7 is connected to one side of the second push rod 411. The side of the storage bag 48 near the second push rod 411 is hollow.
[0027] A second cooling element 12 is connected inside the cooling bag 412. The second cooling element 12 cools the refrigerant inside the cooling bag 412 to increase the cooling time. A storage battery 13 is connected to the outside of the cooling bag 412. The storage battery 13 is electrically connected to the second cooling element 12 to increase the cooling time of the second cooling element 12. The sides of the cooling bag 412 are made of rigid material, while the middle part of the cooling bag 412 is made of flexible material, so that the cooling bag 412 can be pressed.
[0028] The working principle of the above scheme is as follows: After the coolant in the second cold compress bag 43 is heated, the coolant can be squeezed into the cooling bag 412 through the fourth drain pipe 413. At this time, the heated coolant enters the cavity of the cooling bag 412. The coolant is cooled by the second cooling plate 12, so that the coolant can be cooled and reused multiple times. The coolant in the first cold compress bag 42 is squeezed into the second cold compress bag 43, so that the second cold compress bag 43 can be used for cold compress again. At this time, the second push rod 411 is pushed to move the second slide plate 410, squeezing the coolant in the storage bag 48 into the first cold compress bag 42, so that the coolant in the first cold compress bag 42 can be used after the second cold compress bag 43 is used up. When the coolant in the storage bag 48 enters the first cold compress bag 42, the first slide plate 46 can be pushed back, so that the first slide plate 46 can be pushed a second time. After the cooling bag 412 has finished cooling, the coolant is squeezed into the storage bag 48. When the storage bag 48 is full of cooled coolant, the second push rod 411 is pulled to reset the push plate. At this time, the liquid flows through the one-way valve 7 on the second push plate, so that the second push plate can be reset.
[0029] The beneficial effects of the above scheme are as follows: After cooling the injured area of the patient by the second cold compress bag 43, the refrigerant heated in the second cold compress bag 43 is discharged into the cooling bag 412 to continue cooling the coolant so that it can be cooled multiple times. Then the refrigerant in the first cold compress bag 42 is added into the second cold compress bag 43 so that the patient can be continuously cooled. Coolant is added to the first cold compress bag 42 through the storage bag 48, so that after the second cold compress bag 43 has been used for multiple cold compresses, the coolant can be replaced to continue to apply cold compresses to the injured area, which greatly extends the time that can be applied cold compresses, allowing patients to apply cold compresses to the injured area for a long time even when they are outdoors.
