Description

Technical Field

[0001] This invention relates to the field of cold compress device technology, specifically a cold compress device for orthopedic trauma sites. Background Technology

[0002] In the field of trauma orthopedic treatment, cold compresses are an important adjunctive treatment method that plays a key role in relieving pain, reducing swelling, and promoting wound healing. With the development of medical technology, trauma orthopedic cold compress devices have been continuously improved, but there are still some problems that need to be solved.

[0003] Traditional trauma orthopedic cold compress devices inevitably produce condensation during the cold compress process due to the temperature difference between the compress area and the skin. If this condensation is not treated promptly, it will accumulate at the compress site, causing patients to feel damp and uncomfortable, seriously affecting their comfort and treatment experience. At the same time, the damp environment is prone to bacterial growth, increasing the risk of infection, which is extremely detrimental to the patient's wound recovery. Although some existing devices have adopted water-absorbing materials to solve the condensation problem, most of them only passively absorb the condensation and fail to effectively collect and reuse it, resulting in a waste of water resources. Summary of the Invention

[0004] To address the aforementioned problems, the present invention provides a cold compress device for orthopedic trauma sites.

[0005] This invention adopts the following technical solution: a cold compress device for orthopedic trauma sites, comprising a working box, the upper end of which is provided with a control panel and an opening / closing port; two liquid inlets are provided inside the working box; a miniature water pump and a cooling component are provided inside the working box; one end of the miniature water pump is connected to one of the liquid inlets, and the other end of the miniature water pump is connected to a liquid inlet pipe; an elastic sleeve is provided on one side of the working box; Velcro straps are fixed at the four corners of the elastic sleeve; a flexible absorbent block is fixed inside the elastic sleeve; and further comprising:

[0006] The elastic mechanism provides elastic support to the cold compress area and is housed within the elastic sleeve.

[0007] It also includes an automatic water collection mechanism that can automatically discharge condensate according to changes in water level, and the automatic water collection mechanism is housed within an elastic sleeve.

A liquid collection groove is provided through the outer wall of the elastic hollow tube. The elastic hollow tube abuts against a flexible absorbent block. An elastic interlayer is filled inside the flexible absorbent block. A liquid guiding pipe is fixedly connected inside the elastic interlayer. One end of the liquid guiding pipe is fixedly connected to an inlet pipe, and the other end of the liquid guiding pipe is fixedly connected to an outlet pipe. The other end of the outlet pipe is connected to one of the liquid guiding ports.

[0009] As a further description of the above technical solution: the automatic water collection mechanism includes a drain pipe, a trapezoidal sliding plate abutting the side of the elastic hollow tube away from the flexible water-absorbing block, the trapezoidal sliding plate being horizontally slidably disposed within the inner cavity of the elastic sleeve, an extrusion strip abutting the upper end of the trapezoidal sliding plate, the extrusion strip being vertically slidably disposed within the elastic sleeve, a pull rope being fixedly connected to the lower end of the extrusion strip, a connecting block being fixedly connected to the inner wall of the bottom end of the elastic hollow tube, a shuttle-shaped groove being formed in the connecting block, a connecting pipe being connected to the lower side of the drain pipe within the elastic sleeve, a liquid storage strip being fixedly connected to the bottom end of the connecting pipe, an inclined sliding surface being formed in the liquid storage strip, the inner cavity of the liquid storage strip being connected to the connecting pipe, a drain pipe being connected to the bottom end of the liquid storage strip, the drain pipe being connected to the inner cavity of the liquid storage strip and the inner cavity of the working box, a float being fixedly connected to the other end of the pull rope, the float being vertically slidably disposed within the inner cavity of the working box, and the pull rope passing through the elastic sleeve, the connecting pipe, the liquid storage strip and the drain pipe.

[0013] As a further description of the above technical solution: the fluid-guiding laying pipe is S-shaped.

[0014] As a further description of the above technical solution: the extrusion strip and the trapezoidal slide plate are bendable.

[0015] This invention provides an improved cold compress device for orthopedic trauma sites, which has the following improvements and advantages compared to the prior art:

[0016] Firstly, it efficiently handles condensate. The condensate generated by the cold compress is collected by an automatic water collection mechanism and returned to the working box through the drain pipe for reuse. This not only avoids the accumulation of condensate that can cause patients to feel damp and uncomfortable, and breed bacteria that can lead to infection, but also saves water resources and reduces the trouble of frequent water additions.

[0017] Secondly, the elastic hollow tube, combined with the elastic shell, can automatically expand and tighten as the swelling at the patient's wound site subsides, always fitting the cold compress area without manual adjustment. At the same time, the elastic mechanism provides gentle support, improving wearing comfort.

[0018] Thirdly, it prevents postoperative discomfort. The intermittent contraction of the elastic hollow tube driven by water level changes provides a gentle massage to the patient's wound site, avoiding muscle stiffness or blood circulation disorders caused by prolonged cold compresses, further optimizing the treatment experience. Moreover, it can prevent condensation backflow during repositioning, ensuring the effectiveness of the cold compress.

[0019] In summary, the design of the elastic hollow tube provides automatic support and tightening for the patient. It also automatically drains condensate when the liquid level in the working chamber decreases, and automatically contracts according to changes in water level, providing a massage effect and improving patient comfort. Furthermore, the elastic hollow tube can replace elastic components to automatically reset the trapezoidal slide and compression strip. The reset mechanism during drainage prevents backflow of condensate, allowing for multiple uses of condensate and reducing water waste by eliminating the need for frequent refills.

[0030] To make the technical means, creative features, objectives, and effects of this invention readily understandable, the invention is further described below with reference to specific illustrations. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0031] Please see Figure 1 - Figure 8 This invention provides a technical solution: a cold compress device for orthopedic trauma sites, comprising a working box 1, a control panel 2 and an opening / closing port 3 on the upper end of the working box 1, two liquid inlets 9 in the inner cavity of the working box 1, a miniature water pump and a cooling component inside the working box 1, one end of the miniature water pump being connected to one of the liquid inlets 9, and the other end of the miniature water pump being connected to an inlet pipe 7, an elastic sleeve 4 on one side of the working box 1, Velcro straps 5 fixedly attached to the four corners of the elastic sleeve 4, and a flexible absorbent block 6 fixedly attached inside the elastic sleeve 4, and further comprising:

[0032] The elastic mechanism 10 provides elastic support to the cold compress area and is located inside the elastic sleeve 4.

[0033] And an automatic water collection mechanism 11, which can automatically discharge condensate according to water level changes, is installed inside the elastic sleeve 4.

[0034] The elastic sleeve 4 is made of elastic material and can be bent.

[0035] Specifically, the system efficiently treats condensate by collecting the condensate generated during cold compresses through an automatic water collection mechanism 11 and returning it to the working box 1 via a drain pipe 111 for reuse. This not only avoids the accumulation of condensate that could cause discomfort and bacterial growth in patients, but also saves water resources and reduces the inconvenience of frequent water refills.

[0036] The elastic hollow tube 101, combined with the elastic shell 4, can automatically expand and tighten as the swelling of the patient's wound site subsides, always fitting the cold compress area without manual adjustment. At the same time, the elastic mechanism 10 provides gentle support, improving wearing comfort.

[0037] To prevent postoperative discomfort, the elastic hollow tube 101 is intermittently contracted by water level changes, which provides a gentle massage to the patient's wound site, avoiding muscle stiffness or blood circulation disorders caused by prolonged cold compresses, further optimizing the treatment experience. It also prevents condensate backflow during repositioning, ensuring the effectiveness of the cold compress.

[0038] In another embodiment of the present invention, the elastic mechanism 10 includes an elastic hollow tube 101, which is movably disposed within the elastic sleeve 4. A liquid collection slot 104 is provided through the outer wall of the elastic hollow tube 101. The elastic hollow tube 101 abuts against the flexible absorbent block 6. An elastic interlayer 102 is filled inside the flexible absorbent block 6. A liquid guiding pipe 103 is fixedly connected inside the elastic interlayer 102. One end of the liquid guiding pipe 103 is fixedly connected to the inlet pipe 7, and the other end of the liquid guiding pipe 103 is fixedly connected to the outlet pipe 8. The other end of the outlet pipe 8 is connected to one of the liquid guiding ports 9.

[0039] Several elastic hollow tubes 101 are provided, and several elastic hollow tubes 101 are provided at equal intervals along the length of the elastic sleeve 4.

[0040] The liquid collection slots 104 are evenly distributed in a circular linear pattern on the elastic hollow tube 101.

[0041] The fluid-conducting laying pipe 103 is distributed in an S-shape.

[0042] Specifically, the system efficiently treats condensate by collecting the condensate generated during cold compresses through an automatic water collection mechanism 11 and returning it to the working box 1 via a drain pipe 111 for reuse. This not only avoids the accumulation of condensate that could cause discomfort and bacterial growth in patients, but also saves water resources and reduces the inconvenience of frequent water refills.

[0043] The elastic hollow tube 101, combined with the elastic shell 4, can automatically expand and tighten as the swelling at the patient's wound site subsides, always fitting the cold compress area without manual adjustment. At the same time, the elastic mechanism 10 provides gentle support, enhancing wearing comfort.

[0044] In another embodiment of the present invention, the automatic water collection mechanism 11 includes a drain pipe 111. A trapezoidal sliding plate 114 abuts against the side of the elastic hollow tube 101 away from the flexible absorbent block 6. The trapezoidal sliding plate 114 is horizontally slidably disposed within the inner cavity of the elastic sleeve 4. An extrusion strip 115 abuts against the upper end of the trapezoidal sliding plate 114. The extrusion strip 115 is vertically slidably disposed within the elastic sleeve 4. A pull rope 113 is fixedly connected to the lower end of the extrusion strip 115. A connecting block 1110 is fixedly connected to the inner wall of the bottom end of the elastic hollow tube 101. A shuttle-shaped groove 119 is formed inside the connecting block 1110. The drain pipe 111 is located on its lower side... A connecting pipe 116 is connected inside the elastic sleeve 4. A liquid storage strip 112 is fixedly connected to the bottom end of the connecting pipe 116. An inclined sliding surface 117 is opened inside the liquid storage strip 112. The inner cavity of the liquid storage strip 112 is connected to the connecting pipe 116. A drain pipe 111 is connected to the bottom end of the liquid storage strip 112. The drain pipe 111 is connected to the inner cavity of the liquid storage strip 112 and the inner cavity of the working box 1. A float 118 is fixedly connected to the other end of the pull rope 113. The float 118 is slidably arranged in the inner cavity of the working box 1. The pull rope 113 passes through the elastic sleeve 4, the connecting pipe 116, the liquid storage strip 112 and the drain pipe 111.

[0045] The extrusion strip 115 and the trapezoidal slide plate 114 are capable of bending.

[0046] Specifically, to prevent postoperative discomfort, the elastic hollow tube 101 is intermittently contracted by water level changes, which provides a gentle massage to the patient's wound site, avoiding muscle stiffness or blood circulation disorders caused by prolonged cold compresses, further optimizing the treatment experience. It also prevents condensate backflow during repositioning, ensuring the effectiveness of the cold compress.

[0047] Working principle: When a patient is newly injured, the injured area is swollen. When using this device, the cooling component in the working chamber 1 is first used to cool the water inside the working chamber 1. Then, the elastic sleeve 4 is tied to the patient's newly injured area, such as the leg, using Velcro straps 5. The flexible absorbent block 6 is then pressed tightly against the patient's injured area. After that, the miniature water pump inside the working chamber 1 is activated. Through the action of the miniature water pump, the ice water inside the working chamber 1 flows into the inlet pipe 7. Then, the cold water flows through the liquid guiding pipe 103, the outlet pipe 8, and the liquid guiding port 9, returning to the inner cavity of the working chamber 1. The circulation of cooling water can cool both the elastic interlayer 102 and the flexible absorbent block 6, which can remove the water from the patient's injured area. The heat is used to achieve the effect of circulating ice application, keeping the water level in the working box 1 high. At this time, the float 118 can be kept at the top for a long time. The float 118 pulls the pull rope 113, which pulls the squeezing strip 115 downward. The trapezoidal slide plate 114 is squeezed towards the elastic hollow tube 101, thus squeezing the elastic hollow tube 101 flat. The cross-section of the elastic hollow tube 101 is elliptical. Because the elastic hollow tube 101 is elastic, when the swelling of the patient's swollen area is reduced by ice application, the patient's leg volume becomes smaller, and the elastic hollow tube 101 can expand slightly, thus providing automatic support and tightening for the patient.

[0048] When condensation forms between the flexible absorbent block 6 and the area in contact with the patient, the collection groove 104 on the outer wall of the flat, elastic hollow tube 101 opens to collect excess condensation from the flexible absorbent block 6. This condensation is then channeled into the elastic hollow tube 101 for storage, preventing excessive condensation from flowing onto the patient. Because the float 118 remains elevated for an extended period, the elastic hollow tube 101 is compressed for a prolonged time, causing the spindle-shaped groove 119 at the lower end of the elastic hollow tube 101 to remain closed. After the cold compress is complete, the elastic sleeve 4 is removed from the patient and placed near the work box 1. At this time, the pull rope 113 becomes loose, and under the elastic action of the elastic hollow tube 101 itself, the elastic hollow tube 101 resets into a cylinder, the liquid collection tank opening 104 closes, preventing the condensate from flowing back into the flexible water absorption block 6 when draining the condensate. The trapezoidal slide plate 114 and the extrusion strip 115 also reset, the shuttle groove 119 opens automatically, and the condensate stored in the elastic hollow tube 101 is automatically introduced into the inner cavity of the working box 1 through the drain pipe 111. This can clean up the excessive condensate and replenish the water in the working box 1 in time. The condensate serves as a supplementary water source, realizing the reuse of water resources and reducing the trouble of frequent water addition.

[0049] After orthopedic surgery, the water level inside the working chamber 1 is reduced, lowering the position of the float 118. The elastic sleeve 4 is then attached to the corresponding wound site, with the working chamber 1 positioned below the elastic sleeve 4, keeping the pull rope 113 taut and compressing the elastic hollow tube 101. Circulating cold compresses are then applied. During the cold compress, condensation enters the elastic hollow tube 101. Because the working chamber 1 is not usually completely sealed, and the ward is typically at a comfortable temperature, the large temperature difference between the inside and outside of the working chamber 1 causes water evaporation, resulting in a drop in the water level. After the water level in the working chamber 1 is lowered, circulating cooling is performed. When condensation forms on the outside of the fluid-conducting laying tube 103, it will raise... The temperature of the cold water in the high-temperature working chamber 1 causes the water level in the working chamber 1 to drop. When the water level drops, the float 118 also moves down, causing the pull rope 113 to loosen. The elastic hollow tube 101 resets, allowing the condensate to flow back into the inner cavity of the working chamber 1. When the water level in the working chamber 1 rises, the float 118 moves up, which can continue to squeeze the elastic hollow tube 101. This not only allows the condensate to be automatically discharged when the liquid in the working chamber 1 drops, but also allows the elastic hollow tube 101 to automatically contract intermittently. This prevents the patient from experiencing local blood circulation problems or muscle stiffness when applying cold compresses for a long time after surgery. The automatic contraction of the elastic hollow tube 101 can also have a massage effect, improving the patient's comfort.

[0050] The design of the elastic hollow tube 101 can automatically support and tighten the patient, and can also automatically drain condensate when the liquid level in the working box 1 decreases. It can also automatically contract according to the water level change, which can provide a massage effect and improve patient comfort. In addition, the elastic hollow tube 101 can replace the elastic element to automatically reset the trapezoidal slide plate 114 and the compression strip 115. The reset of the elastic hollow tube 101 when draining can prevent the backflow of condensate. The whole can reuse condensate multiple times, reduce water waste, and eliminate the need for multiple replenishments.
