Technical Field
[0001] This utility model relates to the field of medical equipment technology, and more specifically, to an intraoperative body temperature monitoring device. Background Technology
[0002] Surgical treatment refers to the use of surgical methods to remove, repair, or replace diseased organs or organs with morphological defects. It can effectively reduce or improve the symptoms of certain genetic diseases and alleviate the patient's pain. Surgical correction is the main means of surgical treatment. Deformities caused by genetic diseases can be corrected, repaired, or removed through surgery.
[0003] During surgery, it is necessary to monitor the patient's body temperature, which generally requires the use of a temperature monitoring device. Some existing temperature monitoring devices are similar to wristwatches, with the main body of the device fixed to the patient's wrist by two wristbands. However, the two wristbands are limited by the locking blocks and slots, or by the insertion rods and holes. Medical staff need to use both hands to fix it to the patient's wrist, which reduces the convenience of use. Therefore, we provide an intraoperative temperature monitoring device. Utility Model Content
[0004] The purpose of this invention is to provide an intraoperative body temperature monitoring device to solve the problems mentioned in the background art.
[0005] Some existing temperature monitoring devices resemble wristwatches, with the main body of the device fixed to the patient's wrist via two wristbands. However, the two wristbands are limited by clips and slots, or by inserts and holes, requiring medical staff to use both hands to fix them to the patient's wrist, thus reducing the ease of use.
[0006] To achieve the above objectives, this utility model provides the following technical solution:
[0007] An intraoperative body temperature monitoring device includes a first wristband, with a first fixing seat fixedly connected to the top of the first wristband. There are two first fixing seats, symmetrically distributed. A fixing shaft is fixedly connected inside each first fixing seat. A second fixing seat is fitted outside the fixing shaft and to one side of the first fixing seat. The second fixing seat is rotatably connected to the fixing shaft. A second wristband is fixedly connected to the outside of the second fixing seat. The body of the body temperature monitoring device is fixedly connected inside the second wristband. A torsion spring is fitted outside the fixing shaft. The torsion of the torsion spring clamps the first and second wristbands onto the user's wrist, which is more convenient and faster than using two straps for connection and fixation. One end of the torsion spring is fixedly connected to the fixing shaft, and the other end is fixedly connected to the second fixing seat. A first fixing plate is fixedly connected to the top of the first wristband. A first sliding groove is formed inside the first fixing plate, and a second fixing plate is slidably connected inside the first sliding groove. The second fixing plate is fixedly connected to the second wristband. The stability between the first and second wristbands is improved through the first and second fixing plates.
[0008] Preferably, the second wristband has a second sliding groove inside, and a worm gear is slidably connected inside the second sliding groove. The second wristband also has a mounting groove inside, which communicates with the second sliding groove. A worm is installed inside the mounting groove, with one end of the worm passing through the second wristband and extending to the outside of the second wristband. The other end of the worm is rotatably connected to the second wristband. The worm gear is meshed with the other end of the worm. When the worm is rotated, it drives the worm gear to slide in the second sliding groove. Because the worm and the worm gear have a self-locking capability.
[0009] Preferably, the second fixing plate has a third sliding groove inside, and a limiting rod is slidably connected inside the third sliding groove. The limiting rod is fixedly connected to a worm gear. Limiting grooves are opened on both sides of the first fixing plate. The limiting grooves are used in conjunction with the limiting rods. The first sliding grooves are connected to the limiting grooves. The limiting rods, in conjunction with the limiting grooves, can adjust the position of the second fixing plate within the first fixing plate, and ultimately adjust the opening and closing degree of the first and second wristbands, so that the whole can adapt to users with different wrist sizes.
[0010] Preferably, a knob is fixedly connected to the outer end of the worm gear away from the second wristband. Since the overall volume of the worm gear is relatively small, adding a knob to one end of the worm gear makes it easier for medical staff to rotate it.
[0011] Preferably, the first fixing plate, the first sliding groove, the second fixing plate, the second sliding groove, the worm gear, the third sliding groove, and the limiting groove are all arc-shaped structures, and the centers of these arc-shaped components are all on the axis of the fixed shaft.
[0012] Preferably, the outer wall of the worm gear fits against the inner wall of the second slide groove, allowing the worm gear to slide back and forth within the second slide groove. Because the worm gear and the second slide groove fit together, the second slide groove can limit the worm gear, preventing it from wobbling within the second slide groove. The outer wall of the second fixing plate fits against the inner wall of the first slide groove. When medical personnel press to open the first and second wristbands, the second fixing plate will slide within the first slide groove.
[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] Because the first and second wristbands are like a clamp, medical staff only need to press one end of each wristband to separate them. Then, the patient's wrist is placed between the two wristbands. After releasing the grip, the torque of the torsion spring will clamp the first and second wristbands onto the patient's wrist, allowing the medical staff to operate with one hand. The medical staff can rotate the worm gear on the second wristband by turning a knob. The worm gear will drive the worm wheel to move, and the worm wheel will adjust the position of the limit rod in the limit groove, thereby adjusting the opening and closing degree of the first and second wristbands to accommodate patients with different wrist sizes and improve adaptability.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0021] Please see Figures 1 to 4 An intraoperative body temperature monitoring device includes a first wristband 1, with a first fixation seat 2 fixedly connected to the top of the first wristband 1. There are two first fixation seats 2, symmetrically distributed. A fixing shaft 3 is fixedly connected inside the first fixation seat 2. A second fixation seat 4 is sleeved on the outside of the fixing shaft 3, located to one side of the first fixation seat 2, and rotatably connected to the fixing shaft 3. A second wristband 5 is fixedly connected to the outside of the second fixation seat 4. The body 6 of the body temperature monitoring device is fixedly connected inside the second wristband 5. A torsion spring 7 is sleeved on the outside of the fixing shaft 3. The device utilizes the torsion of the torsion spring 7. The first wristband 1 and the second wristband 5 can be clipped onto the user's wrist, which is more convenient and faster than connecting and fixing with two straps. One end of the torsion spring 7 is fixedly connected to the fixed shaft 3, and the other end of the torsion spring 7 is fixedly connected to the second fixed seat 4. The top of the first wristband 1 is fixedly connected to the first fixed plate 8. The first fixed plate 8 has a first sliding groove 9 inside, and the second fixed plate 10 is slidably connected inside the first sliding groove 9. The second fixed plate 10 is fixedly connected to the second wristband 5. The stability between the first wristband 1 and the second wristband 5 is improved by the first fixed plate 8 and the second fixed plate 10.
[0022] Furthermore, the second wristband 5 has a second groove 11 inside, and a worm gear 12 is slidably connected inside the second groove 11. The second wristband 5 also has a mounting groove 13 inside, which communicates with the second groove 11. A worm 14 is installed inside the mounting groove 13. One end of the worm 14 passes through the second wristband 5 and extends to the outside of the second wristband 5. The other end of the worm 14 is rotatably connected to the second wristband 5. The worm gear 12 is meshed with the other end of the worm 14. When the worm 14 is rotated, it will drive the worm gear 12 to slide in the second groove 11. Since the worm 14 and the worm gear 12 have a self-locking capability, the stability between the worm 14 and the worm gear 12 can be ensured.
[0023] Furthermore, a third sliding groove 15 is provided inside the second fixing plate 10. A limiting rod 16 is slidably connected inside the third sliding groove 15. The limiting rod 16 is fixedly connected to the worm gear 12. Limiting grooves 17 are provided on the corresponding two sides of the first fixing plate 8. The limiting grooves 17 and the limiting rods 16 are used in conjunction. The first sliding groove 9 is connected to the limiting grooves 17. The limiting rods 16 and the limiting grooves 17 can adjust the position of the second fixing plate 10 within the first fixing plate 8, and finally adjust the opening and closing degree of the first wristband 1 and the second wristband 5, so that the whole can adapt to users with different wrist sizes and improve adaptability.
[0024] Furthermore, a knob 18 is fixedly connected to the outer end of the worm gear 14 away from the second wristband 5. Since the overall volume of the worm gear 14 is relatively small, adding a knob 18 to one end of the worm gear 14 makes it easier for medical staff to rotate it.
[0025] Furthermore, the first fixed plate 8, the first slide groove 9, the second fixed plate 10, the second slide groove 11, the worm gear 12, the third slide groove 15, and the limiting groove 17 are all arc-shaped structures. The centers of these arc-shaped components are all on the axis of the fixed shaft 3 to prevent jamming.
[0026] Furthermore, the outer wall of the worm gear 12 is fitted with the inner wall of the second slide groove 11, allowing the worm gear 12 to slide back and forth within the second slide groove 11. Because the worm gear 12 and the second slide groove 11 are fitted together, the second slide groove 11 can limit the movement of the worm gear 12, preventing it from wobbling within the second slide groove 11. The outer wall of the second fixing plate 10 is fitted with the inner wall of the first slide groove 9. When medical personnel press and open the first wristband 1 and the second wristband 5, the second fixing plate 10 will slide within the first slide groove 9. The second fixing plate 10 and the first slide groove 9 can improve the stability between the first wristband 1 and the second wristband 5.
[0027] As a preferred implementation, the main body 6 of the body temperature monitoring device adopts a commonly available body temperature detector.
[0028] The steps of using this utility model are as follows: When using this intraoperative temperature monitoring device, since the first wristband 1 and the second wristband 5 are like a clamp, medical staff only need to press one end of the first wristband 1 and the second wristband 5 to separate them. Then, the patient's wrist is placed between the first wristband 1 and the second wristband 5. After releasing the hand, the torque of the torsion spring 7 will cause the first wristband 1 and the second wristband 5 to clamp the patient's wrist. Then, the main body 6 of the temperature monitoring device is used to monitor the patient's body temperature during the operation, making it more convenient for medical staff to complete the operation with one hand. If the patient's wrist is of different thicknesses, the opening degree between the first wristband 1 and the second wristband 5 can also be adjusted. Medical staff can rotate the worm gear 14 on the second wristband 5 through the knob 18. The worm gear 14 will drive the worm wheel 12 to move. The worm wheel 12 will adjust the position of the limit rod 16 in the limit groove 17, thereby achieving the purpose of adjusting the opening degree of the first wristband 1 and the second wristband 5, thus adapting to patients with different wrist thicknesses and improving adaptability.
