Description

Technical Field

[0001] The utility model relates to the technical field of surgical heat preservation, in particular to a device for keeping the limbs of a patient warm during surgery. Background Art

[0002] During surgery, ensuring proper warmth in the patient's extremities is crucial. Surgery itself exposes the patient to relatively low temperatures, and the use of anesthetics can suppress the patient's body's temperature regulation mechanisms, leading to a drop in body temperature and hypothermia. Because the extremities are located farther from the core of the body, blood circulation is relatively poor, making them more susceptible to heat loss. Low body temperature in the extremities can lead to a series of adverse consequences. First, low body temperature can affect coagulation, leading to increased intraoperative bleeding, prolonged surgery, and increased transfusion requirements, thereby increasing surgical risk and the incidence of complications. Second, low body temperature can affect drug metabolism, altering the efficacy and duration of drug action, posing challenges to anesthetic management. Furthermore, it can affect the patient's immune system, increasing the risk of postoperative infection. Furthermore, low body temperature in the extremities can lead to slower recovery, increased pain perception, prolonged hospital stays, and increased medical costs. Therefore, effective measures to warm the extremities and maintain normal body temperature are crucial for improving surgical safety and patient outcomes.

[0003] Currently, thermal blankets and blankets are commonly used in operating rooms. During surgery, this type of thermal insulation method will seriously affect the implementation of the surgery, prolong the operation time and increase safety risks. The thermal insulation effect is also not ideal, which may cause uneven temperature distribution or unstable and uncontrollable temperature. Utility Model Content

[0024] See also Figure 1-5 The utility model provides a device for keeping the limbs of a surgical patient warm during surgery. The device comprises an upper thermal insulation shell 1 and a lower thermal insulation shell 2. The lower thermal insulation shell 2 is provided at the bottom of the upper thermal insulation shell 1. A heating unit 3 is provided inside the upper thermal insulation shell 1 and the lower thermal insulation shell 2. The heating unit 3 provides heating for the limbs during surgery. A clamping assembly is provided inside the left and right sides of the upper thermal insulation shell 1 and the lower thermal insulation shell 2. The clamping assembly is used to fix the thermal insulation layer 9 to facilitate replacement of the thermal insulation layer 9.

[0025] The clamping assembly includes a strip card plate 4, a push-pull block 5, a fixing frame 6 and a clamping block 7. The surface of the strip card plate 4 is provided with a groove matching the clamping block 7. The fixing frame 3 can cooperate with the clamping block 7 and the strip card plate 4 to complete the clamping work, which is convenient for replacement. The bottom end of the clamping assembly is provided with an insulation layer 9. The insulation layer 9 can effectively conduct the heat generated by the heating unit 3 to the patient's skin and avoid the problem of local temperature not being conducted. The top of the insulation layer 9 is provided with a flame retardant layer 8. The flame retardant layer 8 can effectively reduce safety hazards and avoid causing harm to the patient. The right outer wall of the upper insulation shell 1 is provided with two first elastic bands 10. The first elastic band 10 plays the role of elastically connecting the upper insulation shell 1 and the lower insulation shell 2. The other end of the first elastic band 10 is provided on the left outer wall of the lower insulation shell 2. A connecting assembly is provided on the left side of the upper insulation shell 1. The connecting assembly is worn in conjunction with the upper insulation shell 1 and the lower insulation shell 2. The top outer wall of the upper insulation shell 1 is provided with a temperature display 13.

[0026] The clamping assembly includes a strip card plate 4, which is arranged on both sides of the upper insulation shell 1. A push-pull block 5 is provided at the front end of the strip card plate 4. The push-pull block 5 is used to pull the strip card plate 4 out from the inside of the upper insulation shell 1 and insert it. A clamping block 7 is provided at the bottom end of the push-pull block 5. The clamping block 7 is clamped and connected to the strip card plate 4. The clamping block 7 uses an I-shaped clamping block. The I-shaped clamping block can cooperate with the strip card block 4 to better complete the clamping. A fixed frame 6 is provided at the bottom end of the clamping block 7. The frame 6 is connected to the strip card plate 4 through the clamping block 7. The strip card plate 4 fixes and cancels the clamping block 7. When the fixed frame 6 is subjected to pressure, the clamping block 7 is moved into the strip card plate 4, making the clamping of the strip card plate 4 and the clamping block 7 more convenient. Pull the push-pull block 5 to complete the clamping task. When the fixed frame 6 is removed, the insulation layer 9 and the flame retardant layer 8 will be removed at the same time for easy maintenance or replacement.

[0027] The strip-shaped card plate 4 is provided with a plurality of grooves matching the card block 7 , one end of the groove matches the outer diameter of the card block 7 , and the other end matches the diameter of the central cylinder of the card block 7 .

[0028] An electric power conductor is provided between the heating unit 3 of the upper heat-insulating shell 1 and the heating unit 3 of the lower heat-insulating shell 2 , and a suitable length of the electric power conductor needs to be reserved in advance.

The mother patch is arranged on the left side of the outer wall of the lower thermal insulation shell 2, and the child patch is arranged on the left side of the outer wall of the second elastic band 11. The Velcro can enable the upper thermal insulation shell 1 and the lower thermal insulation shell 2 to wrap the patient's limbs to prevent heat loss.

[0030] Working principle: When the utility model is in use, the card block 7 of the outer wall of the fixed frame 6 is inserted into the groove in the strip card plate 4. At this time, the push-pull block 5 is pushed. The push-pull block 5 is driven by the thrust to drive the strip card plate 4 to move inward inside the upper heat-insulating shell 1. The groove in the strip card plate 4 moves inward accordingly, so that the card block 7 enters the interior of the strip card plate 4 and is clamped and fixed. At this point, the clamping is completed, and then the patient's limb is placed in the lower heat-insulating shell 2, and then the upper heat-insulating shell 1 is placed above the patient's limb, and the second elastic band 11 is used to fit the appropriate position of the Velcro 12 Fix it, and start the heating unit 3 after fixation. At this time, the temperature display 13 starts to display the real-time temperature for easy temperature control. The installation is now completed. When disassembling after the operation, disconnect the second elastic band 11 from the Velcro 12, remove the upper insulation shell 1, and take the patient's limb out of the lower insulation shell 2. Push the push-pull block 5. The push-pull block 5 is pushed to drive the strip card plate 4 to move inward, and the groove set on the strip card plate 4 moves inward, so that the card block 7 can be disengaged from the card connection of the strip card block 4. Remove the fixing frame 6 and the insulation layer 9 for maintenance or cleaning.
