Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to an intraoperative warming bag. Background Technology

[0002] Currently, maintaining patient body temperature during surgery primarily involves using warming blankets and raising the overall temperature of the operating room. However, most warming blankets often fail to achieve satisfactory temperature control. Furthermore, due to surgical exposure and intraoperative irrigation, traditional warming methods alone often fall short of ideal results, potentially leading to postoperative hypothermia, shivering, slowed metabolism, and delayed recovery.

[0003] Therefore, there is an urgent need to develop a thermal bag that can heat and keep the patient warm during surgery, and can cover the untreated parts of the patient's torso and limbs to avoid postoperative hypothermia, shivering, slow metabolism, and delayed awakening. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide an intraoperative warming bag to solve the above-mentioned problems.

[0005] The technical solution adopted by this utility model is:

[0006] An intraoperative warming bag includes an inner liner and an outer liner. The outer liner includes several interconnected outer liner units. Each outer liner unit includes an outer insulating layer, an insulating layer, and an inner insulating layer arranged sequentially from the outside to the inside. The outer insulating layer and the inner insulating layer are connected at the edge of the outer liner unit.

[0007] The heat-insulating bag is provided with several air supply sections, including vents opened on the outer liner unit and detachable seals on the vents; after the seals are opened, heated gas is sent through the vents into the space between the inner and outer liners to heat and keep the patient warm.

[0008] As one embodiment of the present invention, the heat-insulating bag further includes an air guide tube and a flexible card plate disposed at one end of the air guide tube. The flexible card plate is placed between the inner lining and the outer lining through the vent. The size and shape of the flexible card plate are larger than the size and shape of the vent, so that the flexible card plate is secured between the inner lining and the outer lining.

[0009] The other end of the air duct is connected to the heat source mechanism and the air source mechanism.

[0010] In one embodiment of this utility model, the flexible cardboard is made of silicone.

[0011] In one embodiment of this utility model, the insulation layer is made of insulation cotton, the outer insulation layer is made of non-woven fabric, and the inner insulation layer is made of elastic TPU hot melt adhesive film. The outer insulation layer and the inner insulation layer at the edge of the outer lining unit are hot-melted together to form a hot melt indentation.

[0012] As one embodiment of this utility model, the heat-insulating bag adopts a front-opening or back-opening structure.

[0013] As one embodiment of this utility model, the heat-insulating bag includes a heat-insulating bag body, an arm and a leg connected to the heat-insulating bag body, and the ends of the arm and the leg are provided with a closing structure.

[0014] In one embodiment of this utility model, the closing structure adopts a Velcro structure or an elastic band structure.

[0015] In one embodiment of this utility model, a cap is connected to the heat-insulating bag, and the air supply part is provided on the cap.

[0016] In one embodiment of this utility model, the seal is made of medical adhesive tape, which is adhered to the outside of the thermal insulation outer layer and covers the vent.

[0017] The beneficial effects of adopting the above technical solution are as follows:

[0018] The insulated bag described in this application adopts a front-opening or back-opening design. When the patient is supine during surgery, the bag can be inserted from the back; when the patient is prone, it can be inserted from the front. After insertion, the patient lies on the bed, and medical staff cut open the insulated bag in the area to be operated on, exposing the patient's skin. Medical tape is then used to attach the cut edges to the patient's body for surgery, preventing heat loss and separating the surgical and non-surgical areas. The heat-fused indentation structure formed by the thermal fusion of the outer and inner insulated layers effectively prevents the insulation filler from overflowing from uncut areas and ensures the integrity of the rest of the insulated bag. During surgery, hot air can be introduced between the outer and inner linings of the insulated bag through air vents to enhance the insulation effect. Multiple air supply points are located on the insulated bag; the appropriate placement of these points can adapt to various surgical scenarios, and the sealing strip reduces the leakage of hot air from other vents, minimizing heat loss.

The bag body 100 includes an inner liner 4 and an outer liner, with a gap between them for airflow. In this embodiment, the inner liner 4 and the outer liner are connected by stitching at a closure structure or suitable location, further increasing the integrity of the warming bag after the surgical area has been cut. See also... Figures 5 to 9The outer lining comprises several interconnected outer lining units. Each outer lining unit includes an outer insulating layer 1, an insulating layer 2, and an inner insulating layer 3 arranged sequentially from the outside to the inside. The outer insulating layer 1 and the inner insulating layer 3 at the edges of the outer lining units are heat-fused to form heat-fused indentations 7, making the outer lining units independent of each other and facilitating the preservation of the integrity of the remaining insulation bags during cutting. Preferably, the outer insulating layer 1 and the inner insulating layer 3 can be connected by thread sewing.

[0033] See also Figures 1 to 4 The insulated bag is provided with several air supply sections 400, each including a vent 5 opened on the outer lining unit and a seal 6 detachably mounted on the vent 5; after the seal 6 is opened ( Figure 2 (The seal 6 on the upper right shoulder has been opened), and heated gas is sent through the vent 5 between the inner liner 4 and the outer liner to heat and keep the patient warm.

The insulation layer 2 is made of insulation cotton, the outer insulation layer 1 is made of non-woven fabric, and the inner insulation layer 3 is made of elastic TPU hot melt adhesive film. In this embodiment, a hydrophobic layer can be provided on the outside of the outer insulation layer 1 to prevent medication and wound fluid from seeping into the lining of non-surgical areas during surgery.

[0037] See Figure 1 A cap 300 is connected to the body 100 of the heat-insulating bag, and an air supply part 400 is provided on the cap 300. The sealing strip 6 is made of medical adhesive tape and is adhered to the outside of the heat-insulating outer layer 1, covering the ventilation opening 5.

[0038] Example 2:
