Description

Technical Field

[0001] This invention relates to the field of medical device technology, specifically to an ice pack and positioning device located at the tonsils in the neck. Background Technology

[0002] Patients who have undergone tonsillectomy are prone to postoperative symptoms such as pain and bleeding, which directly affect postoperative recovery and the patient's quality of life. Therefore, ice pack therapy is often used in clinical practice to treat postoperative discomfort.

[0003] The existing ice pack therapy refers to a treatment method in which an ice pack is wrapped in a towel and placed on the body where needed, so that the local capillaries constrict, thereby achieving a series of effects such as cooling, heat dissipation, pain relief, hemostasis, swelling reduction, and infection prevention.

[0004] However, in actual use, simply wrapping the ice pack in a towel and placing it on the patient's neck cannot stabilize it well. Moreover, the location of postoperative pain varies from patient to patient, so patients or their families need to manually press the ice pack on the neck and move it multiple times according to the location of pain to relieve pain. This makes it impossible to effectively adjust the position of the ice pack, resulting in a poor patient experience and delaying recovery time. Therefore, this application provides an ice pack and positioning device located at the tonsils in the neck. Summary of the Invention

[0005] The purpose of this application is to address the problem that postoperative pain locations vary among different patients, requiring patients to manually press ice packs onto their necks and move the ice packs multiple times according to the location of the pain, making it difficult to effectively adjust the position of the ice pack. This application provides an ice pack and positioning device located at the tonsils in the neck.

[0006] To achieve the above objectives, this application specifically adopts the following technical solution:

[0007] An ice pack and positioning device located at the cervical tonsils include a restraint strap with multiple positioning holes evenly distributed on the restraint strap. Two ice packs are mounted on the restraint strap, and a U-shaped plate is fixedly connected to one side of each ice pack. The U-shaped plate is slidably fitted onto the restraint strap. Through holes are symmetrically distributed on one side of the U-shaped plate. A positioning component is mounted on the U-shaped plate. A waterproof cloth is fixedly connected inside each ice pack. A zipper is installed at the top of each ice pack. A compression component is installed inside each ice pack. A detection component is installed on one side of each ice pack.

[0008] By adopting the above technical solution, the required ice pack is placed inside the ice pack by unzipping it and then the zipper is closed. After the device is fixed to the patient's neck, the connection between the U-shaped plate and the restraint strap can be released by squeezing the positioning component. This allows the position of the ice pack inside the ice pack to be adjusted according to the location of the patient's neck pain. Once the ice pack is in the appropriate position, the squeezing component can be activated to inflate the ice pack inside. Squeezing the ice pack inside the ice pack allows it to better fit the patient's neck, significantly improving the ice pack effect. Furthermore, due to the continuous influence of the patient's body temperature, the ice pack inside the ice pack will melt and gradually return to room temperature after a period of time. At this time, the detection component can detect the temperature change inside the ice pack in real time. When a specified value is reached, an alarm will be issued to remind the patient or family to replace the ice pack in time, greatly improving the practicality of the device.

[0009] Furthermore, the positioning component includes a support plate symmetrically fixedly connected to the bottom of the U-shaped plate. A rotating rod is rotatably connected to one side of the support plate. A fixing plate is fixedly connected to the rotating rod. An L-shaped plate is fixedly connected to one side of the fixing plate. A positioning rod is symmetrically fixedly connected to one side of the L-shaped plate. The positioning rod has the same size as the through hole and positioning hole on one side of the U-shaped plate.

[0010] By adopting the above technical solution, pressing the bottom end of the L-shaped plate and rotating it around the rotating rod as the center will gradually separate the two positioning rods from the positioning holes and through holes, thereby detaching the connection between the U-shaped plate and the restraint strap. At this time, the U-shaped plate can be pulled to move the ice pack on the restraint strap, thereby adjusting the position of the ice pack according to the location of the patient's pain, and more effectively relieving pain in wounds at different locations.

[0011] Furthermore, a rotating rod is rotatably connected to one side of the support plate, a fixing plate is fixedly connected to the rotating rod, a spring is fixedly connected to one side of the fixing plate, and one end of the spring is fixedly connected to one side of the L-shaped plate.

[0012] By adopting the above technical solution, when the pressure on the L-shaped plate is released, the spring will cause one side of the L-shaped plate to re-fit with the other side of the U-shaped plate, thereby allowing the positioning rod to be inserted into the through hole and the positioning hole. This frees up the hands of the patient and their family and allows the position of the ice pack to be adjusted and positioned at will, so as to more effectively and quickly relieve pain in the wound.

[0013] Furthermore, a magnet is fixedly connected to the top of the L-shaped plate, and a magnet is fixedly connected to the top of the U-shaped plate.

[0014] By adopting the above technical solution, the L-shaped plate can be more stably fixed to one side of the U-shaped plate through the mutual attraction between the magnet and the magnet, so that the ice pack will not shake or fall off when the patient moves significantly.

[0015] Furthermore, absorbent cotton is fixedly connected to the bottom surface inside the ice pack, and skin-friendly cotton is fixedly connected to one side of the ice pack.

[0016] By adopting the above technical solution, the skin-friendly cotton between the ice pack and the patient's neck can prevent direct contact between the ice pack and the patient, effectively improving the patient's comfort. The absorbent cotton inside can effectively prevent the liquid generated by the melting ice pack from overflowing from the ice pack.

[0017] Furthermore, the compression assembly includes an inflatable bladder fixedly connected to one side of the inside of the ice pack, an air supply tube fixedly connected through one side of the inflatable bladder, a micro pump fixedly connected to one side of the ice pack, the output end of the micro pump fixedly connected to one end of the air supply tube, an exhaust pipe fixedly connected through the top of the inflatable bladder, and a one-way valve fixedly connected to the exhaust pipe.

[0018] By adopting the above technical solution, the micro pump is activated to inflate the inside of the air bladder. The inflated air bladder can then press the ice pack on the waterproof cloth side forward, allowing the ice pack to fit better against the patient's neck and significantly improving the ice application effect of the device.

[0019] Furthermore, the detection component includes a temperature sensor fixedly connected to one side of the inside of the ice pack, a controller fixedly connected to one side of the ice pack, an alarm fixedly connected to the top of the controller, and both the temperature sensor and the alarm being electrically connected to the controller.

[0020] By adopting the above technical solution, when the temperature sensor detects that the temperature is gradually rising and reaches the specified temperature, it can transmit the information to the controller. When the controller receives the signal from the temperature sensor, it will activate the alarm to remind the patient or family to change the ice pack in time, which greatly improves the practicality of the device.

[0021] Furthermore, one end of the restraint strap is fixedly connected to an elastic band, one end of the elastic band is fixedly connected to a connecting band, one side of the connecting band is fixedly connected to a Velcro strap, and the side of the restraint strap away from the elastic band is fixedly connected to a Velcro strap.

[0022] By adopting the above technical solution, the elastic band can be used to stretch the connecting band. Then, according to the size of the patient's neck, the Velcro 1 and Velcro 2 on one side of the connecting band can be pulled to fit together, so that the tightness of the device can be adjusted according to the size of the patient's neck, freeing the patient's or family's hands and allowing the device to be stably and continuously fixed to the patient's neck.

[0023] In summary, this application includes at least one of the following beneficial effects;

[0024] 1. This application includes a positioning component. By rotating the L-shaped plate, the two positioning rods gradually separate from the positioning holes and through holes, thereby releasing the connection between the U-shaped plate and the restraint strap. At this time, the U-shaped plate can be pulled to move the ice pack on the restraint strap, thereby adjusting the position of the ice pack according to the patient's pain location, and more effectively relieving pain in wounds at different locations. Subsequently, the L-shaped plate is released, allowing the positioning rods to be inserted into the through holes and positioning holes, so that the U-shaped plate can be firmly positioned on the restraint strap. This ensures that the ice pack will not shake or fall off when the patient moves significantly, freeing the hands of the patient and their family and allowing the position of the ice pack to be adjusted and positioned at will, providing more effective and faster pain relief for the wound.

[0025] 2. This application includes a squeezing component and a detection component. Once the ice pack is positioned and stabilized, the squeezing component can be activated to inflate the ice pack inside. The inflated squeezing component can compress the ice pack inside the ice pack to better fit the patient's neck, effectively improving the ice pack effect. At the same time, the detection component can monitor the temperature change inside the ice pack in real time. When a specified value is reached, an alarm will be issued to remind the patient or family to replace the ice pack in time, greatly improving the practicality of the device.

[0026] 3. This application includes an elastic band, a connecting band, Velcro 1, and Velcro 2. The elastic band can be used to stretch the connecting band by pulling it. Then, Velcro 1 and Velcro 2 on one side of the connecting band can be pulled to fit together according to the size of the patient's neck. This allows the device to adjust the tightness according to the size of the patient's neck, freeing the hands of the patient or family members and allowing the device to be stably and continuously fixed to the patient's neck.

[0034] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0035] This application discloses an ice pack and positioning device located at the cervical tonsils.

[0036] Reference Figure 1 , Figure 2 and Figure 3 An ice pack and positioning device located at the tonsils in the neck includes a restraint strap 1 with multiple positioning holes 110 evenly distributed on the restraint strap 1. Two ice packs 2 are installed on the restraint strap 1, and a U-shaped plate 21 is fixedly connected to one side of each ice pack 2. The U-shaped plate 21 is slidably fitted onto the restraint strap 1. A through hole is symmetrically opened on one side of the U-shaped plate 21. A positioning component 3 is installed on the U-shaped plate 21. A waterproof cloth 4 is fixedly connected inside the ice pack 2. A zipper 5 is installed on the top of the ice pack 2. A compression component 8 is installed inside the ice pack 2. A detection component 9 is installed on one side of the ice pack 2. A water-absorbing cotton 6 is fixedly connected to the bottom surface inside the ice pack 2. A skin-friendly cotton 7 is fixedly connected to one side of the ice pack 2. An elastic band 10 is fixedly connected to one end of the restraint strap 1. A connecting band 11 is fixedly connected to one end of the elastic band 10. A Velcro fastener 12 is fixedly connected to one side of the connecting band 11. A Velcro fastener 2 13 is fixedly connected to the end of the restraint strap 1 away from the elastic band 10.

[0037] In use, first unzip 5, place the desired ice pack inside the ice pack 2, and close zip 5. Then, according to the size of the patient's neck, pull the Velcro 12 and Velcro 23 on one side of the connecting strap 11 to fit together, allowing the device to adjust the tightness according to the patient's neck size, freeing the patient's or family member's hands and ensuring the device is stably and continuously fixed to the patient's neck. After the device is fixed to the patient's neck, the connection between the U-shaped plate 21 and the restraint strap 1 can be released by squeezing the positioning component 3. Then, pull the U-shaped plate 21 to move the ice pack 2 on the restraint strap 1, thereby adjusting the tightness according to the patient's neck pain. The position of the ice pack inside the ice pack 2 is adjusted according to the pain location. After the ice pack is adjusted to the appropriate position, the positioning component 3 can be released to limit and fix the ice pack 2, so that the ice pack 2 will not shift during use. After the position of the ice pack is stabilized, the squeezing component 8 can be activated to inflate the ice pack 2. The inflated squeezing component 8 can squeeze the ice pack inside the ice pack 2 to better fit the patient's neck, greatly improving the ice pack effect. At the same time, the skin-friendly cotton 7 between the ice pack and the patient's neck can prevent the ice pack from directly contacting the patient, effectively improving the patient's comfort.

[0038] Secondly, due to the continuous influence of the patient's body temperature, the ice pack inside the ice pack 2 will melt and gradually turn to room temperature after a period of time. At this time, the detection component 9 can detect the temperature change inside the ice pack 2 in real time. When the specified value is reached, an alarm will be issued to remind the patient or family to replace the ice pack in time, which greatly improves the practicality of the device. At the same time, the internal absorbent cotton 6 can effectively prevent the liquid generated by the melting ice pack from overflowing from the ice pack 2.

[0039] Reference Figure 1 and Figure 2 The positioning component 3 includes a support plate 31 symmetrically fixedly connected to the bottom of the U-shaped plate 21. A rotating rod 32 is rotatably connected to one side of the support plate 31. A fixing plate 33 is fixedly connected to the rotating rod 32. An L-shaped plate 34 is fixedly connected to one side of the fixing plate 33. A positioning rod 341 is symmetrically fixedly connected to one side of the L-shaped plate 34. The positioning rod 341 is the same size as the through hole and positioning hole 110 on one side of the U-shaped plate 21. A rotating rod 35 is rotatably connected to one side of the support plate 31. A fixing plate 36 is fixedly connected to the rotating rod 35. A spring 37 is fixedly connected to one side of the fixing plate 36. One end of the spring 37 is fixedly connected to one side of the L-shaped plate 34. A magnet 38 is fixedly connected to the top of the L-shaped plate 34. A magnet 39 is fixedly connected to the top of the U-shaped plate 21.

[0040] When using it, first press the bottom end of the L-shaped plate 34 so that one end of the L-shaped plate 34 rotates around the rotating rod 32. When the L-shaped plate 34 rotates, it will drive the two positioning rods 341 to gradually separate from the positioning hole 110 and the through hole, thereby releasing the connection between the U-shaped plate 21 and the restraint belt 1. At this time, the U-shaped plate 21 can be pulled to move the ice pack 2 on the restraint belt 1, so as to adjust the position of the ice pack according to the location of the patient's pain, and more effectively relieve pain in wounds at different locations.

[0041] Subsequently, once the position of the ice pack 2 is adjusted, the pressure on the L-shaped plate 34 can be released. At this time, according to the extension and rebound of the spring 37, one side of the L-shaped plate 34 will re-fit with one side of the U-shaped plate 21, thereby allowing the positioning rod 341 to be inserted into the through hole and the positioning hole 110. Through the cooperation between the positioning rod 341 and the through hole and the positioning hole 110, the U-shaped plate 21 can be firmly positioned on the restraint strap 1. At the same time, through the mutual attraction between the magnet 38 and the magnet 39, the L-shaped plate 34 can be more stably fixed on one side of the U-shaped plate 21. Thus, when the patient moves significantly, the ice pack 2 will not shake or fall off, freeing the hands of the patient and family members and allowing the position of the ice pack to be adjusted and positioned at will, providing more effective and faster pain relief for the wound.

[0042] Reference Figure 1 and Figure 4 The compression assembly 8 includes an inflatable bladder 81 fixedly connected to one side inside the ice pack 2. An air supply pipe 82 is fixedly connected through one side of the inflatable bladder 81. A micro pump 83 is fixedly connected to one side of the ice pack 2. The output end of the micro pump 83 is fixedly connected to one end of the air supply pipe 82. An exhaust pipe 84 is fixedly connected through the top of the inflatable bladder 81. A one-way valve 85 is fixedly connected to the exhaust pipe 84.

[0043] When in use, the micro pump 83 can be started to inflate the air bag 81, causing the air bag 81 to gradually expand. The expanded air bag 81 can press the ice pack on one side of the waterproof cloth 4 forward, so that the ice pack fits the patient's neck better and greatly improves the ice application effect of the device. After the ice application is finished, the one-way valve 85 can be opened to discharge the gas inside the air bag 81 through the exhaust pipe 84.

[0044] Reference Figure 1 and Figure 5 The detection component 9 includes a temperature sensor 91 fixedly connected to one side inside the ice pack 2, a controller 92 fixedly connected to one side of the ice pack 2, and an alarm 93 fixedly connected to the top of the controller 92. Both the temperature sensor 91 and the alarm 93 are electrically connected to the controller 92.

[0045] During use, the ice pack inside the ice pack 2 will melt and gradually return to room temperature after a period of time due to the continuous influence of the patient's body temperature. At this time, the temperature sensor 91 will continuously monitor the temperature inside the ice pack 2. When the temperature sensor 91 detects that the temperature is gradually rising and reaches the specified temperature, it can transmit the information to the controller 92. When the controller 92 receives the signal from the temperature sensor 91, it will activate the alarm 93 to sound an alarm, thereby reminding the patient or family members to replace the ice pack in time, which greatly improves the practicality of the device.

[0046] The implementation principle of the ice pack and positioning device located at the tonsil in the neck in this embodiment is as follows: When in use, first unzip 5, put the required ice pack into the ice pack 2 and close zip 5. Then, according to the size of the patient's neck, pull the Velcro 12 and Velcro 23 on one side of the connecting strap 11 to fit together, so that the device can adjust the tightness according to the size of the patient's neck, freeing the patient's or family's hands, and so that the device can be stably and continuously fixed on the patient's neck.

[0047] Secondly, after the device is fixed to the patient's neck, the bottom end of the L-shaped plate 34 can be pressed to make one end of the L-shaped plate 34 rotate around the rotating rod 32. When the L-shaped plate 34 rotates, it will drive the two positioning rods 341 to gradually separate from the positioning hole 110 and the through hole, thereby releasing the connection between the U-shaped plate 21 and the restraint belt 1. At this time, the U-shaped plate 21 can be pulled to move the ice pack 2 on the restraint belt 1, thereby adjusting the position of the ice pack according to the location of the patient's pain, and more effectively relieving pain in wounds at different locations.

[0048] Subsequently, once the position of the ice pack 2 is adjusted, the pressure on the L-shaped plate 34 can be released. At this time, according to the extension and rebound of the spring 37, one side of the L-shaped plate 34 will be moved back to fit against one side of the U-shaped plate 21, so that the positioning rod 341 can be inserted into the through hole and the positioning hole 110. Through the cooperation of the positioning rod 341 with the through hole and the positioning hole 110, the U-shaped plate 21 can be firmly positioned on the restraint strap 1. At the same time, through the mutual attraction between the magnet 38 and the magnet 39, the L-shaped plate 34 can be more stably fixed on one side of the U-shaped plate 21. Thus, when the patient moves significantly, the ice pack 2 will not shake or fall off. This frees the hands of the patient and family members and allows the position of the ice pack to be adjusted and positioned at will, providing more effective and faster pain relief for the wound.

[0049] In addition, once the ice pack is positioned and stabilized, the micro pump 83 can be activated to inflate the air bladder 81, causing the air bladder 81 to gradually expand. The expanded air bladder 81 can then press the ice pack against the waterproof cloth 4 side, allowing the ice pack to better fit the patient's neck and significantly improving the ice pack's effect. After the ice pack application is complete, the one-way valve 85 can be opened to release the gas inside the air bladder 81 through the exhaust pipe 84. Meanwhile, the skin-friendly cotton 7 between the ice pack and the patient's neck prevents direct contact between the ice pack and the patient, effectively improving the patient's comfort.

[0050] Secondly, due to the continuous influence of the patient's body temperature, the ice pack inside the ice pack 2 will melt and gradually return to room temperature after a period of time. At this time, the temperature sensor 91 will continuously monitor the temperature inside the ice pack 2. When the temperature sensor 91 detects that the temperature is gradually rising and reaches the specified temperature, it can transmit the information to the controller 92. When the controller 92 receives the signal from the temperature sensor 91, it will activate the alarm 93 to sound an alarm, thereby reminding the patient or family members to replace the ice pack in time, which greatly improves the practicality of the device. At the same time, the internal absorbent cotton 6 can effectively prevent the liquid generated by the melting ice pack from overflowing from the ice pack 2.
