Description

Technical Field

[0001] This invention relates to the field of medical device technology, specifically to a pressurized cooling device for orthopedic nursing. Background Technology

[0002] Clinically, in the field of orthopedics, patients with ankle sprains or post-fracture surgery often require local ice application to constrict blood vessels, reduce swelling, relieve pain, and suppress inflammatory responses. Currently, the most commonly used cooling device is the ice pack. The specific method involves wrapping the ice pack in a towel and manually pressing it onto the affected area, or having the patient wear a restraint device with an attached ice pack.

[0003] When using the aforementioned cooling device to cool a patient, the cooling primarily relies on the ice water inside the ice pack. Since commonly used ice packs are typically sealed bags containing ice water, it is difficult to replace the liquid inside the ice pack during use. This results in a short application time for a single ice pack. Consequently, when a patient requires prolonged ice application, several ice packs usually need to be replaced to achieve continuous ice application. This frequent replacement of ice packs during prolonged application increases the inconvenience of using the cooling device.

[0004] Therefore, improving the cooling endurance of cooling devices is a technical problem that urgently needs to be solved. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of commonly used cooling devices in actual use by providing a pressurized cooling device for orthopedic care, thereby improving the cooling endurance of the device.

[0006] To achieve the above-mentioned objectives, the present invention provides the following technical solution:

[0007] A pressure-cooling device for orthopedic nursing includes a fluid infusion device and a sleeve. The sleeve is used to bind the patient's limb and is a bag-like structure capable of containing liquid. The fluid infusion device has a receiving cavity, and a baffle is provided in the receiving cavity. The baffle divides the receiving cavity into a first chamber and a second chamber. The second chamber is located above the first chamber. The first chamber is connected to a water inlet, and the second chamber is connected to a water outlet. Both the water inlet and the water outlet are connected to the sleeve.

[0008] The baffle is connected to a push rod, which is adapted to a drive assembly. The drive assembly is used to drive the push rod to reciprocate along the length of the push rod, so that the push rod pushes the baffle to reciprocate vertically.

[0009] A first one-way valve is provided at the water inlet end, which is used to allow liquid to flow unidirectionally from the second chamber to the sleeve; a second one-way valve is provided at the water outlet end, which is used to allow liquid to flow unidirectionally from the sleeve to the second chamber; a third one-way valve is provided on the baffle, which is used to allow liquid to flow unidirectionally from the second chamber to the first chamber.

[0010] The push rod is provided with a telescopic section, which is elastic and can extend and retract along the length of the push rod. The second chamber is used to hold ice and water. When there is ice in the second chamber, during the reciprocating motion of the baffle driven by the push rod, in each reciprocating motion, the baffle can move upward until the ice is pressed against the top of the receiving cavity before moving downward. When the ice is pressed against the top of the receiving cavity, the distance between the baffle and the top of the receiving cavity is proportional to the amount of shortening of the telescopic section.

[0011] As the preferred technical solution of this application, during the reciprocating motion of the push rod driving the baffle, in each single reciprocating motion, the baffle can move downward to the point where the baffle abuts against the bottom of the receiving cavity before moving upward.

[0012] Furthermore, the water inlet is located at the bottom of the receiving cavity.

[0013] As the preferred technical solution of this application, the driving component includes a first rack, a second rack, and a sector gear. The first rack and the second rack are both mounted on the push rod. The sector gear alternately meshes with the first rack or the second rack to drive the push rod to reciprocate along its own length.

[0014] As the preferred technical solution of this application, the push rod is divided into a push rod section one, a telescopic section and a push rod section two along its length direction. The push rod section one is connected to the baffle, and the push rod section two is connected to the drive assembly.

[0015] The liquid replenishment device is provided with a first through hole. During the reciprocating motion of the push rod, the first through hole is always in contact with a section of the push rod to prevent the liquid in the first chamber from leaking out along the side wall of the push rod.

[0016] As the preferred technical solution of this application, the telescopic section includes a telescopic section body and a first spring. The first spring is sleeved on the telescopic section body and has elasticity. The telescopic section body includes a plurality of sleeves with adjacent sleeves sleeved together. The sleeve located at the head of the telescopic section body is connected to a first section of the push rod, and the sleeve located at the tail of the telescopic section body is connected to a second section of the push rod.

[0017] One end of the first spring abuts against the sleeve located at the head of the telescopic section body, and the other end abuts against the sleeve located at the tail of the telescopic section body.

[0018] As the preferred technical solution of this application, a funnel-shaped groove is formed on the upper part of the baffle, and the third one-way valve is located at the lowest point of the groove.

[0019] As a preferred technical solution of this application, the top of the receiving cavity is formed with a funnel-shaped protrusion, which is adapted to the funnel-shaped groove.

[0020] As the preferred technical solution of this application, a filter screen is provided at the lowest point of the groove. The filter screen is used to allow liquid to pass through and to block ice. The filter screen covers the third one-way valve.

[0021] As the preferred technical solution of this application, the liquid replenishment device is provided with a feeding port, which is used to inject ice and / or water into the second chamber. A feeding cover is detachably provided on the feeding port, which is used to seal the feeding port.

[0022] As the preferred technical solution of this application, the sleeve is provided with a liquid injection port, which is used to inject liquid into the sleeve.

[0023] As the preferred technical solution of this application, the sleeve can be unfolded into a strip or rolled into a tube. One end of the sleeve is provided with a Velcro female and the other end is provided with a Velcro female. When the Velcro female and the Velcro female are attached, the sleeve can be rolled into a tube to restrain the patient's limb.

[0024] As the preferred technical solution of this application, the sleeve includes a sleeve body, an inlet pipe and an outlet pipe, wherein one end of the inlet pipe is connected to the sleeve body and the other end is connected to the inlet end, one end of the outlet pipe is connected to the sleeve body and the other end is connected to the outlet end, and the part on the sleeve body for connecting the inlet pipe and the part on the sleeve body for connecting the outlet pipe are opposite to each other, thereby further facilitating water circulation within the sleeve body.

[0025] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0026] 1. In the solution of this application, while ensuring that the speed of the drive component driving the push rod remains constant, when there is a lot of ice in the second chamber, the movement amplitude of the baffle is small in a single reciprocating motion cycle of the baffle, resulting in less water exchange in the sleeve and less water flowing from the outlet to the second chamber. Since there is a lot of ice at this time, the water is cooled by the ice faster. In this way, the water with a faster cooling speed and a smaller amount participates in the water circulation of the sleeve, which can prevent the water in the bag from being over-cooled when there is a lot of ice.

[0027] Meanwhile, when there is less ice, the baffle moves more in a single reciprocating cycle, resulting in more water exchange within the casing. More water flows from the outlet to the second chamber. Since there is less ice at this time, more water is cooled by the ice. This allows water with a slower cooling rate and a larger volume to participate in the water circulation within the casing, ensuring that water with a slower cooling rate can also have a better cooling effect on the water inside the bag.

[0028] 2. During the continuous movement of the push rod driven by the drive component, there is a situation where ice and water separate in the receiving cavity, that is, water is separated into the first chamber and ice is retained in the second chamber. Since water has good thermal conductivity, the separation of ice and water can slow down the heating rate of ice, thereby slowing down the melting rate of ice, thus further improving the cooling endurance of the pressurized cooling device of this application.

[0029] 3. The side walls of the receiving cavity can be made of light-shielding material, preventing light from penetrating the side walls of the receiving cavity and exposing the telescopic section on the push rod to the field of vision. During the movement of the push rod, the telescopic section will not extend into the receiving cavity. Thus, only the extension and retraction of the telescopic section needs to be observed, without the need for additional observation devices, to estimate the remaining amount of ice in the receiving cavity. This improves the heat preservation effect of the receiving cavity and also allows for real-time monitoring of the remaining amount of ice in the second chamber.

[0030] 4. In a single reciprocating motion, the baffle can move downwards to the bottom of the receiving cavity and then move upwards, so that the water inlet is located at the bottom of the receiving cavity. This makes it easier to squeeze all the water in the first chamber into the water inlet when the baffle moves downwards, further improving the efficiency of water circulation in the casing.

[0031] 5. By setting a first rack, a second rack, and a sector gear, the sector gear can alternately mesh with the first rack or the second rack, thereby driving the push rod to reciprocate along its own length, thus improving the convenience of driving the push rod to reciprocate. In addition, the sector gear is adapted to a motor and is set on the output shaft of the motor. By controlling the speed of the motor, the speed of the push rod can be controlled.

[0032] 6. By forming a funnel-shaped groove to collect ice and water, and placing the third one-way valve at the lowest point of the groove, it is easier to transport water from the second chamber to the first chamber when the third one-way valve is open. Attached Figure Description

[0045] Example 1: This example provides a pressurized cooling device for orthopedic nursing care. See [link to example]. Figures 1-5 As shown, the device includes a fluid infusion device 1 and a sleeve 2. The sleeve 2 is used to bind the patient's limb and is a bag-like structure that can hold liquid. The fluid infusion device 1 has a receiving cavity 3, and a baffle 4 is provided in the receiving cavity 3. The baffle 4 divides the receiving cavity 3 into a first chamber 5 and a second chamber 6. The second chamber 6 is located above the first chamber 5. The first chamber 5 is connected to a water inlet 7, and the second chamber 6 is connected to a water outlet 8. Both the water inlet 7 and the water outlet 8 are connected to the sleeve 2.

[0046] The baffle 4 is connected to a push rod 9, and the push rod 9 is adapted to a drive assembly 10. The drive assembly 10 is used to drive the push rod 9 to reciprocate along the length of the push rod 9, so that the push rod 9 pushes the baffle 4 to reciprocate vertically.

[0047] A first one-way valve 11 is provided at the water inlet 7, which allows liquid to flow unidirectionally from the second chamber 6 to the sleeve 2; a second one-way valve 12 is provided at the water outlet 8, which allows liquid to flow unidirectionally from the sleeve 2 to the second chamber 6; a third one-way valve 13 is provided on the baffle 4, which allows liquid to flow unidirectionally from the second chamber 6 to the first chamber 5.

[0048] The push rod 9 is provided with a telescopic section 14, which is elastic and can extend and retract along the length of the push rod 9. The second chamber 6 is used to contain ice and water. When there is ice in the second chamber 6, during the reciprocating motion of the baffle 4 driven by the push rod 9, in each reciprocating motion, the baffle 4 can move upward until the ice is pressed against the top of the receiving cavity 3 and then move downward. When the ice is pressed against the top of the receiving cavity 3, the distance between the baffle 4 and the top of the receiving cavity 3 is proportional to the shortening of the telescopic section 14.

[0049] In this application, when using the orthopedic nursing pressure cooling device, water can first be poured into the sleeve 2, and ice and water can be injected into the second chamber 6. When injecting ice and water into the second chamber 6, the sleeve 2 can be moved to the bottom of the receiving cavity 3. Then, the drive assembly 10 is activated, causing the drive assembly 10 to drive the push rod 9 to reciprocate, thereby causing the push rod 9 to push the baffle 4 to reciprocate vertically. During the process of the push rod 9 pushing the baffle 4 to reciprocate vertically, in a single reciprocating motion, the movement of the push rod 9 is decomposed into a vertically upward movement and a vertically downward movement. During the process, when push rod 9 moves vertically upward, push rod 9 drives baffle 4 to move vertically upward, causing the volume of the second chamber 6 to gradually decrease. Under the action of the first one-way valve 11, the second one-way valve 12, and the third one-way valve 13, the first one-way valve 11 and the second one-way valve 12 are both closed, and the third one-way valve 13 is in the open state, allowing the water in the second chamber 6 to gradually flow into the first chamber 5, causing the ice to gradually separate from the water. As the ice is gradually pressed against the top of baffle 4 and the receiving cavity 3, baffle 4 no longer moves vertically upward. At this time, push rod 9 is still pushed vertically upward by the drive assembly 10, and the degree of compression of its telescopic section 14 increases, so as to... This increases the pressure exerted on the top of the baffle 4 and the receiving cavity 3 to compress the ice, and ensures that the baffle 4 will not continue to move upward. Then, when the push rod 9 moves vertically downward, the telescopic section 14 on the push rod 9 will preferentially recover its deformation, causing the pressure exerted on the top of the baffle 4 and the receiving cavity 3 to gradually decrease. Then, the baffle 4 is driven by the push rod 9 to move vertically downward, causing the volume of the second chamber 6 to gradually increase and the volume of the first chamber 5 to gradually decrease. During the process of the second chamber 6 gradually increasing and the first chamber 5 gradually decreasing, the third one-way valve 13 closes, and the first one-way valve 11 and the second one-way valve 12 can be in the open state. This allows water in the first chamber 5 to flow into the sleeve 2 via the first one-way valve 11, and water in the sleeve 2 to flow into the second chamber 6 via the second one-way valve 12. Simultaneously, when the baffle 4 is stationary, the preload of the spring in its one-way valve keeps the first one-way valve 11, the second one-way valve 12, and the third one-way valve 13 closed. Furthermore, when injecting ice into the second chamber 6, the selected ice blocks are small ice blocks with a volume of 0.4 cubic centimeters to 4 cubic centimeters, and the number of these small ice blocks is several. The volume of the receiving chamber 3 can be 1 liter to 4 liters, and the volume ratio of ice blocks injected into the second chamber 6 to the water can be 50% to 90%.

[0050] Thus, while ensuring that the speed of the drive component 10 driving the push rod 9 remains constant, when there is a lot of ice in the second chamber 6, the movement amplitude of the baffle 4 is small in a single reciprocating motion cycle, resulting in less water exchange in the sleeve 2 and less water flowing from the water outlet 8 to the second chamber 6. Since there is a lot of ice at this time, the water is cooled by the ice faster. In this way, the water with a faster cooling speed and a smaller amount participates in the water circulation of the sleeve 2, which can prevent the water in the bag from being over-cooled when there is a lot of ice.

[0051] Meanwhile, when there is less ice, the baffle 4 moves more during a single reciprocating cycle, resulting in more water exchange within the sleeve 2. More water flows from the outlet 8 to the second chamber 6. Since there is less ice at this time, more water is cooled by the ice. Thus, a larger amount of water with a slower cooling rate participates in the water circulation of the sleeve 2, ensuring that water with a slower cooling rate can also have a better cooling effect on the water inside the bag.

[0052] Furthermore, during the continuous movement of the push rod 9 driven by the drive assembly 10, there is a situation where ice and water separate within the receiving cavity 3. That is, water is separated into the first chamber 5, while ice remains in the second chamber 6. Since water has good thermal conductivity, the separation of ice and water can slow down the rate of temperature rise of the ice, thereby slowing down the melting rate of the ice, which further improves the cooling endurance of the pressurized cooling device of this application.

[0053] Meanwhile, the side wall of the receiving cavity 3 can be made of light-shielding material, so that light cannot penetrate the side wall of the receiving cavity 3, and the telescopic section 14 on the push rod 9 is exposed to the field of vision. During the movement of the push rod 9, the telescopic section 14 will not extend into the receiving cavity 3. Thus, it is only necessary to observe the extension and retraction of the telescopic section 14, without the need to set up an additional observation device, so as to estimate the remaining amount of ice in the receiving cavity 3. This not only improves the heat preservation effect of the receiving cavity 3, but also allows for real-time monitoring of the remaining amount of ice in the second chamber 6.

[0054] The specific structures of the first check valve 11, the second check valve 12, and the third check valve 13 are all common check valve structures in the prior art, and can be referenced. Figure 2 , Figure 4 and Figure 5 As shown, it will not be elaborated here.

[0055] As a preferred embodiment, based on the above method, further, during the process of the push rod 9 driving the baffle 4 to reciprocate, in each reciprocating motion, the baffle 4 can be moved downward to the point where the baffle 4 abuts against the bottom of the receiving cavity 3 before moving upward.

[0056] Furthermore, the water inlet 7 is located at the bottom of the receiving cavity 3.

[0057] Furthermore, in each reciprocating motion, the baffle 4 can move downwards to the bottom of the receiving cavity 3 and then move upwards, so that the water inlet 7 is located at the bottom of the receiving cavity 3. This allows the baffle 4 to squeeze all the water in the first chamber 5 into the water inlet 7 when it moves downwards, thereby further improving the efficiency of water circulation in the sleeve 2.

[0058] In a preferred embodiment, based on the above method, the drive assembly 10 further includes a first rack 15, a second rack 16, and a sector gear 17. The first rack 15 and the second rack 16 are both mounted on the push rod 9. The sector gear 17 alternately meshes with the first rack 15 or the second rack 16 to drive the push rod 9 to reciprocate along its own length.

[0059] Furthermore, by setting a first rack 15, a second rack 16, and a sector gear 17, the sector gear 17 can alternately mesh with the first rack 15 or the second rack 16, thereby driving the push rod 9 to reciprocate along its own length direction, thus improving the convenience of driving the push rod 9 to reciprocate. In addition, the sector gear 17 is adapted to a motor 18, and the sector gear 17 is set on the output shaft of the motor 18. By controlling the speed of the motor 18, the speed of the push rod 9 can be controlled.

[0060] Example 2: Based on the technical solution of Example 1, further details are provided below. Figures 1-5 As shown, the push rod 9 is divided into a push rod section 19, a telescopic section 14 and a push rod section 20 along its length direction. The push rod section 19 is connected to the baffle 4, and the push rod section 20 is connected to the drive assembly 10.

[0061] The liquid replenishment device 1 is provided with a first through hole 21. During the reciprocating motion of the push rod 9, the first through hole 21 is always in contact with the first section 19 of the push rod to prevent the liquid in the first chamber 5 from leaking out along the side wall of the push rod 9.

[0062] Furthermore, by providing a first through hole 21 on the liquid replenishment device 1, the first through hole 21 can always be in contact with the push rod section 19, thereby preventing the liquid in the first chamber 5 from leaking out along the side wall of the push rod 9, thus improving the water leakage prevention performance of the pressurization and cooling device of this application.

[0063] As a preferred embodiment, based on the above method, the telescopic section 14 further includes a telescopic section body 22 and a first spring 23. The first spring 23 is sleeved on the telescopic section body 22 and has elasticity. The telescopic section body 22 includes a plurality of sleeves, with adjacent sleeves sleeved together. The sleeve located at the head of the telescopic section body 22 is connected to the first section 19 of the push rod, and the sleeve located at the tail of the telescopic section body 22 is connected to the second section 20 of the push rod.

[0064] One end of the first spring 23 abuts against the sleeve located at the head of the telescopic section body 22, and the other end abuts against the sleeve located at the tail of the telescopic section body 22.

[0065] Furthermore, by setting the telescopic section body 22 and the first spring 23, the convenience of shortening or extending the telescopic section 14 is further improved. The elasticity of the first spring 23 ensures that when the push rod 9 supports the baffle 4 and the ice and water on the baffle 4, and the ice does not abut against the top of the receiving cavity 3, the first spring 23 is not significantly compressed. That is, the shortening of the first spring 23 is less than 11% of the total length of the spring when the first spring 23 is not deformed.

[0066] As a preferred embodiment, based on the above method, the upper part of the baffle 4 is further provided with a funnel-shaped groove 24, and the third one-way valve 13 is located at the lowest point of the groove 24.

[0067] Furthermore, by forming a funnel-shaped groove 24 to collect ice and water, and placing the third one-way valve 13 at the lowest point of the groove 24, it is easier to transport water from the second chamber 6 to the first chamber 5 when the third one-way valve 13 is in the open state.

[0068] As a preferred embodiment, based on the above method, the top of the receiving cavity 3 is further provided with a funnel-shaped protrusion 25, which is adapted to the funnel-shaped groove 24.

[0069] Furthermore, by providing a funnel-shaped protrusion 25 at the top of the receiving cavity 3 and adapting the protrusion 25 to the funnel-shaped groove 24, it is possible to further facilitate the compression of the ice block by the baffle 4 and the top of the receiving cavity 3.

[0070] Example 3: Based on the technical solution of Example 2, further details are provided below. Figures 1-6 As shown, a filter screen 26 is provided at the lowest point of the groove 24. The filter screen 26 is used to allow liquid to pass through and to block ice. The filter screen 26 covers the third one-way valve 13.

[0071] Furthermore, by setting up a filter 26, the filter 26 can block ice blocks, thereby further improving the stability of the second chamber 6 in containing ice blocks.

[0072] As a preferred embodiment, based on the above method, the replenishment device 1 is further provided with a feed port 27, which is used to inject ice and / or water into the second chamber 6. A feed cover 28 is detachably provided on the feed port 27, which is used to seal the feed port 27.

[0073] Furthermore, by setting up the feed port 27, the convenience of injecting ice and water into the second chamber 6 is further improved.

[0074] As a preferred embodiment, based on the above method, the sleeve 2 is further provided with a liquid injection port 29, which is used to inject liquid into the sleeve 2.

[0075] Furthermore, by setting up the injection port 29, the convenience of injecting water into the sleeve 2 is improved.

[0076] As a preferred embodiment, based on the above method, the sleeve 2 can be further unfolded into a strip or rolled into a tube. One end of the sleeve 2 is provided with a hook and loop fastener 30, and the other end is provided with a hook and loop fastener 31. When the hook and loop fastener 30 and the hook and loop fastener 31 are attached, the sleeve 2 can be rolled into a tube to bind the patient's limb.

[0077] At the same time, after the patient's limbs are put on the sleeve 2, the sleeve 2 can apply pressure to the patient's limbs, thereby achieving the effect of pressurization and cooling.

[0078] As a preferred embodiment, based on the above method, the sleeve 2 further includes a sleeve body 32, an inlet pipe 33, and an outlet pipe 34. One end of the inlet pipe 33 is connected to the sleeve body 32, and the other end is connected to the inlet end 7. One end of the outlet pipe 34 is connected to the sleeve body 32, and the other end is connected to the outlet end 8. The part on the sleeve body 32 for connecting the inlet pipe 33 and the part on the sleeve 2 for connecting the outlet pipe 34 are opposite to each other, thereby further facilitating water circulation within the sleeve body 32.

[0079] Furthermore, a flow channel is provided at the protrusion 25, which is connected to the second one-way valve 12. A filter screen 26 is also provided below the flow channel to prevent ice from entering the second one-way valve 12 from the second chamber 6.

[0080] The above embodiments are only used to illustrate the present invention and are not intended to limit the technical solutions described herein. Although the present invention has been described in detail with reference to the above embodiments, the present invention is not limited to the specific embodiments described above. Therefore, any modifications or equivalent substitutions to the present invention, as well as all technical solutions and improvements that do not depart from the spirit and scope of the invention, are covered within the scope of the claims of the present invention.
