Description

Technical Field

[0001] The invention relates to the technical field of medical devices, in particular to a protective cover component after replantation of severed fingers. Background Art

[0002] Kirschner wires, a commonly used internal fixation material in orthopedics, are used to fix fractures with little stress, such as short fractures or avulsion fractures. They are also used to fix temporary fracture fragments in orthopedic surgery.

[0003] At present, after the patient's distal phalanx is fixed with a Kirschner wire, the outer end of the Kirschner wire usually exposes the fingertip of the affected finger. During activities, the affected finger is easily bumped and squeezed, and the Kirschner wire is easily scratched and pulled out, causing injury and increasing the patient's pain. Once the above phenomenon occurs, medical staff need to use the Kirschner wire to readjust the affected finger, which increases the workload of medical staff.

[0004] The existing protective cover after finger replantation is used to protect the affected finger, and the existing patent CN220735573U can be referred to. However, the above technology still has shortcomings: the existing protective cover has poor thermal insulation effect, the ambient temperature inside the thermal cover is low and the humidity is high, which can easily lead to slow wound healing and is not conducive to recovery. Summary of the invention

[0005] The purpose of the present invention is to provide a protective cover assembly after replantation of severed fingers, which protects and keeps the affected fingers warm through the finger cover, generates hot air through a circulating hot air blower, appropriately increases the temperature in the finger cover cavity and reduces the humidity, promotes wound healing, and facilitates recovery.

[0006] In order to achieve the above-mentioned object of the invention, the present invention adopts the following technical solutions: A protective cover component for post-replantation of severed fingers comprises a finger cover and a circulating hot air blower. The finger cover is made of a rigid heat-insulating material. The cover cavity of the finger cover can accommodate an affected finger and the outer end of a Kirschner wire. The cover opening of the finger cover is provided with a cuff ring that can undergo elastic deformation. The cuff ring is made of rubber and is clamped at the root of the affected finger. An inlet and an outlet are arranged outside the finger cover. The circulating hot air blower is provided with an air outlet duct and an air return duct, which are respectively connected to the inlet and the outlet. Hot air generated by the circulating hot air blower flows from the air outlet duct through the cover cavity of the finger cover back to the air return duct.

[0007] Compared with the prior art, the protective sleeve assembly after finger replantation using the above technical solution has the following beneficial effects: 1. With the protective cover assembly for post-severed finger replantation surgery of the present invention, the medical staff pulls open the cuff ring and inserts the affected finger into the cavity of the finger cover from the cover opening, then loosens the cuff ring and clamps the cuff ring around the base of the affected finger, so that the finger cover is covered outside the affected finger, and the affected finger is protected by the finger cover.

[0008] Second, the hot air circulation in the hood cavity is realized through the air outlet duct and the return air duct. The circulating hot air blower can refer to the existing hot air circulation oven. The circulating hot air blower is equipped with a temperature and humidity sensor, a heater, a blower, a humidifier and a PLC control system. The temperature and humidity sensor detection head is set in the finger hood cavity, which can monitor the temperature and humidity in the hood cavity in real time and transmit the monitoring data to the PLC control system. The PLC control system adopts the PID control algorithm to compare the difference between the actual temperature and the target temperature, and the difference between the actual humidity and the target humidity. According to the temperature and humidity changes in the hood cavity, the working state of the heater, blower and humidifier equipment is adjusted in real time to achieve accurate control of the temperature and humidity in the hood cavity. The circulating hot air blower is equipped with a touch screen outside, which is electrically connected to the PLC control system. The touch screen displays the temperature and humidity in the hood cavity and can be adjusted through the touch screen. The drawstring ring closes the hood mouth, keeps the heat through the finger hood, and generates hot air through the circulating hot air blower, which appropriately increases the temperature and reduces the humidity in the hood cavity, promotes wound healing, and is conducive to recovery.

[0009] Preferably, the inlet is located near the fingertip of the affected finger and connected to the air outlet duct, and the outlet is located near the root of the affected finger and connected to the return air duct, so that the hot air can be conducted to the entire affected finger, thereby improving the healing effect.

[0010] Preferably, the finger cover is provided with a finger clamping mechanism, which includes a knob and two clamping plates. The two clamping plates are respectively arranged on both sides of the cover cavity and are close to and away from each other. A clamping opening is formed in the middle of the two clamping plates. An elastomer is provided between the clamping plate and the inner wall of the cover cavity. The elastomer is made of elastic rubber material. A through hole is provided in the elastomer. A pull rope is provided in the through hole. The finger cover is provided with a rope placement channel and a button placement opening. The knob is threadedly connected to the inner circumference of the button placement opening, and the pull ropes of the two clamping plates are respectively fixed to the inner end of the knob through the rope placement channel: when the knob is rotated forward, the knob is rotated out of the button placement opening, and the two clamping plates are driven away from each other by the pull rope, the clamping opening is opened and the affected finger is released, and the elastomer is compressed; when the knob is rotated reversely, the knob is rotated into the button placement opening, the elastomer returns to its original state, drives the two clamping plates close to each other, closes the clamping opening and clamps the affected finger. Before the affected finger is inserted into the mask cavity, the medical staff turns the knob forward to open the clamp mouth, so that the affected finger can be inserted into the mask cavity and placed in the clamp mouth; after the affected finger is inserted into the mask cavity, the medical staff turns the knob backward to close the clamp mouth, so that the affected finger is clamped between the two splints, and the affected finger in the mask cavity is fixed, so that the finger mask is not easy to separate from the affected finger. The opening and closing of the clamp mouth is controlled by turning the knob, which is easy to operate.

[0011] Preferably, there are two finger clamping mechanisms, which are respectively arranged at the positions corresponding to the proximal phalanx and the distal phalanx of the affected finger, so as to enhance the fixation between the affected finger and the finger cover.

[0012] Preferably, the finger cover is retractable, and the retracting direction of the finger cover is the same as the length direction of the finger cover. The length of the finger cover can be adjusted according to needs, and is suitable for affected fingers of different lengths.

[0013] Preferably, the finger cover comprises a cover top and a cover bottom, and the cover top and the cover bottom are threadedly connected. After the length of the finger cover is adjusted, it is firmer to prevent the finger cover from accidentally extending and retracting, thereby preventing the outer end of the Kirschner wire at the fingertip of the affected finger from being bumped, thereby improving safety.

[0014] Preferably, a rotatable screw-on part is provided at the top of the cover, the screw-on part is threadedly connected to the bottom of the cover, slides are provided at both sides of the top of the cover, and slide grooves are provided at both sides of the bottom of the cover. The slides at both sides move in the slide grooves at both sides, and the movement direction of the slides is the same as the extension and retraction direction of the finger cover. Medical staff controls the extension and retraction of the finger cover by rotating the screw-on part. During the extension and retraction of the finger cover, the slide groove limits the slide to prevent the top of the cover from detaching from the bottom of the cover and preventing the top of the cover from rotating relative to the bottom of the cover, so that the two splints are always located on both sides of the affected finger during the extension and retraction of the finger cover.

[0015] Preferably, a sealing tape is wrapped around the outer periphery of the cuff ring, and the two ends of the sealing tape are fixed by Velcro. The sealing tape is used to tighten the cuff ring, thereby enhancing the fixation between the affected finger and the finger mask, making it difficult for the finger mask to separate from the affected finger, being suitable for affected fingers of different sizes, and preventing the gas in the mask cavity from overflowing, thereby improving the heat preservation effect.

DETAILED DESCRIPTION

[0023] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the specific implementation mode, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0024] like Figures 1 to 6 The protective cover assembly after replantation of severed fingers shown in the figure comprises a finger cover 1 and a circulating hot air blower 2. The finger cover 1 is made of a rigid heat-insulating material. The cover cavity 4 of the finger cover 1 can accommodate an affected finger 35 and an outer end 36 of a Kirschner wire. The cover opening 10 of the finger cover 1 is provided with a cinch ring 14 that can undergo elastic deformation. The cinch ring 14 is made of rubber material and is clamped at the base of the affected finger 35. An inlet 17 and an outlet 18 are provided on the outside of the finger cover 1. The circulating hot air blower 2 is provided with an air outlet duct 21 and an air return duct 22. The air outlet duct 21 and the air return duct 22 are respectively connected to the inlet 17 and the outlet 18. The hot air generated by the circulating hot air blower 2 flows from the air outlet duct 21 through the cover cavity 4 of the finger cover 1 and back to the air return duct 22. The medical staff pulls open the cuff 14 and inserts the affected finger 35 into the mask cavity 4 of the finger mask 1 through the mask opening 10, then loosens the cuff 14 and clamps the cuff 14 around the base of the affected finger 35, so that the finger mask 1 is covered outside the affected finger 35, and the affected finger 35 is protected by the finger mask 1.

[0025] Among them, hot air circulation in the hood cavity 4 is realized by the outlet duct 21 and the return duct 22. The circulating hot air blower 2 can refer to the existing hot air circulation oven. The circulating hot air blower 2 is equipped with a temperature and humidity sensor, a heater, a blower, a humidifier and a PLC control system. The temperature and humidity sensor detection head is arranged in the hood cavity 4 of the finger hood 1, which can monitor the temperature and humidity in the hood cavity 4 in real time, and transmit the monitoring data to the PLC control system. The PLC control system is electrically connected to the heater, blower and humidifier equipment. The PLC control system adopts a PID control algorithm to compare the difference between the actual temperature and the target temperature, and the difference between the actual humidity and the target humidity. According to the changes in temperature and humidity in the hood cavity 4, the working status of the heater, blower and humidifier equipment is adjusted in real time to achieve precise control of the temperature and humidity in the hood cavity 4. The circulating hot air blower 2 is provided with a touch screen 23 outside, and the touch screen 23 is electrically connected to the PLC control system. The touch screen 23 displays the temperature and humidity in the hood cavity 4, and can be adjusted through the touch screen 23. The cinch ring 14 closes the mask opening 10, keeps the finger mask 1 warm, and generates hot air through the circulating hot air blower 2, which appropriately increases the temperature and reduces the humidity in the mask cavity 4, promotes wound healing, and facilitates recovery.

[0026] Reference Figure 1 and Figure 6The finger cover 1 is provided with a finger clamping mechanism, which includes a knob 31 and two clamping plates 32. The two clamping plates 32 are respectively arranged on both sides of the cover cavity 4 and are close to and far away from each other. A clamping opening is formed in the middle of the two clamping plates 32. An elastic body 33 is arranged between the clamping plates 32 and the inner wall of the cover cavity 4. The elastic body 33 is made of elastic rubber material. A through hole 40 is arranged in the elastic body 33. A pull rope 34 is arranged in the through hole 40. The finger cover 1 is provided with a rope channel 30 and a button opening 3. The knob 31 and the inner periphery of the button opening 3 The two splints 32 are connected by threaded connection, and the pull ropes 34 of the two splints 32 are respectively fixed to the inner end of the knob 31 through the rope channel 30: when the knob 31 is rotated forward, the knob 31 is rotated out of the button opening 3, and the two splints 32 are driven away from each other through the pull rope 34, the clamping opening is opened and the affected finger 35 is released, and the elastic body 33 is compressed; when the knob 31 is rotated reversely, the knob 31 is rotated into the button opening 3, and the elastic body 33 is restored to its original state to drive the two splints 32 to move closer to each other, close the clamping opening and clamp the affected finger 35. Before the affected finger 35 is inserted into the mask cavity 4, the medical staff rotates the knob 31 forward to open the clamping opening, so that the affected finger 35 can be inserted into the mask cavity 4 and placed in the clamping opening; after the affected finger 35 is inserted into the mask cavity 4, the medical staff rotates the knob 31 reversely to close the clamping opening, so that the affected finger 35 is clamped between the two splints 32, and the affected finger 35 in the mask cavity 4 is fixed, so that the finger mask 1 is not easy to be separated from the affected finger 35. The opening and closing of the clamping mouth can be controlled by turning the knob 31, which is easy to operate.

[0027] There are two finger clamping mechanisms, which are respectively arranged at the positions of the proximal phalanx and the distal phalanx of the affected finger 35 to enhance the fixation between the affected finger 35 and the finger cover 1. The knobs 31 of the two finger clamping mechanisms are both arranged on the same surface of the finger cover 1 for easy operation.

[0028] Reference Figure 1 and Figure 2 The finger cover 1 can be retracted, and the retracting direction of the finger cover 1 is the same as the length direction of the finger cover 1. The length of the finger cover 1 can be adjusted according to needs, and is suitable for affected fingers 35 of different lengths.

[0029] The finger cover 1 includes a cover top 11 and a cover bottom 12. The cover top 11 is provided with a rotatable screw-on part 13, and the screw-on part 13 is threadedly connected to the cover bottom 12. Slides 15 are provided on both sides of the cover top 11, and slide grooves 16 are provided on both sides of the cover bottom 12. One end of the slide 15 is fixed to the outer wall of the cover top 11, and the other end of the slide 15 moves in the slide groove 16. The moving direction of the slide 15 is the same as the extension and retraction direction of the finger cover 1. Medical staff control the extension and retraction of the finger cover 1 by rotating the screw-on part 13: when the screw-on part 13 rotates forward, the screw-on part 13 is screwed out of the cover bottom 12, so that the finger cover 1 is extended; when the screw-on part 13 rotates reversely, the screw-on part 13 is screwed into the cover bottom 12, so that the finger cover 1 is shortened. During the extension and retraction process of the finger cover 1, the slide groove 16 limits the slide plate 15, preventing the cover top 11 from being separated from the cover bottom 12 and preventing the cover top 11 from rotating relative to the cover bottom 12, so that the two splints 32 are always located on both sides of the affected finger 35 during the extension and retraction process of the finger cover 1. After the length of the finger cover 1 is adjusted, it is more firm, preventing the finger cover 1 from accidentally extending and retracting, causing the outer end 36 of the Kirschner wire at the fingertip of the affected finger 35 to be bumped, thereby improving safety.

[0030] Reference Figure 3 The inlet 17 is arranged on the outer side of the cover top 11 near the fingertip of the affected finger 35, and the inlet 17 is connected to the air outlet 21. The outlet 18 is arranged on the outer side of the cover bottom 12 near the root of the affected finger 35, and the outlet 18 is connected to the return air duct 22. The hot air can be conducted to the entire affected finger 35, thereby improving the healing effect.

[0031] The cinch ring 14 is wrapped with a sealing tape 19, and the two ends of the sealing tape 19 are fixed by Velcro. The sealing tape 19 can refer to the existing Velcro cable tie. The cinch ring 14 is tightened by the sealing tape 19 to enhance the fixation between the affected finger 35 and the finger mask 1, so that the finger mask 1 is not easy to be separated from the affected finger 35, and is suitable for affected fingers 35 of different sizes. It also prevents the gas in the mask cavity 4 from overflowing, and improves the heat preservation effect.
