Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a medical heating blanket. Background Technology

[0002] During anesthesia and surgery, medical staff typically use hot water bottles, blankets, and other artificial warming methods to maintain the patient's body temperature. Unfortunately, ordinary cotton blankets and hot water bottles are not effective in maintaining the patient's body temperature. With the development of technology and the times, air-filled heating (that is, heating the air with heating equipment and then sending the hot air into the warming blanket through air ducts, continuing this process to achieve the effect of keeping the patient warm) has emerged as a method of keeping patients warm.

[0003] Currently, the therapeutic effect of air-supplied medical heating blankets mainly relies on the airflow created by the blanket under the air pressure provided by the main unit to cover the patient's entire body. However, in actual clinical use, the airflow channel design of the blanket may not be suitable for the user's body shape, or doctors may not use it as intended, causing the airflow to not be open as designed, thus affecting the product's therapeutic effect. At the same time, because the torso of the human body exerts significant pressure on the blanket when on the operating table, the airflow is generally not open at the points of pressure, resulting in a loss of heating effect and failing to achieve a good heating effect. In order to address the above-mentioned defects, this application is proposed. Utility Model Content

[0004] The purpose of this invention is to provide a medical heating blanket that improves the pressure resistance of the heating blanket, addresses the problem of airflow obstruction when the blanket is under pressure, and enhances the heating efficiency of the blanket on the human torso and its adaptability to people of different body types.

[0005] To address the aforementioned problems, this utility model provides a medical heating blanket that solves the issue of airflow blockage caused by patient pressure. It includes a breathable layer, an air-blocking layer, and a pressure-resistant structure. A gas channel exists between the breathable layer and the air-blocking layer for the flow of hot air generated by the main unit. The pressure-resistant structure is positioned between the breathable layer and the air-blocking layer. When the gas channel is compressed, the pressure-resistant structure supports the breathable layer and the air-blocking layer, preventing complete contact between them and thus preserving at least a portion of the gas channel. This improves the problem of airflow obstruction under pressure, increases thermal efficiency, and ensures the heating effect of the blanket.

[0006] According to one embodiment of the present invention, the anti-pressure structures have several passages between them, and adjacent passages are interconnected, such as "well" or "mouth" shaped passages.

[0007] According to one embodiment of the present invention, the pressure-bearing end face of the pressure-resistant structure is a non-flat structure, which can retain more gas flow space after the breathable layer comes into contact with the pressure-resistant structure under pressure; when not under pressure, the height of the gas channel is higher than the height of the pressure-resistant structure.

[0008] According to one embodiment of the present invention, the cross-section of the pressure-resistant structure is concave.

[0009] According to one embodiment of the present invention, the cross-section of the pressure-resistant structure is convex.

[0010] According to one embodiment of the present invention, the anti-pressure structure adopts a strip structure, forming a passage between adjacent strip structures, or a dot structure.

[0011] Optionally, the strip structures can be set separately or connected into one unit by a connecting structure. The integrated structure is easier to install, but care should be taken to ensure that the connecting structure does not block the passage.

[0012] According to one embodiment of the present invention, the pressure-resistant structure is connected to the gas barrier layer.

[0013] According to one embodiment of the present invention, the pressure-resistant structure is connected to the breathable layer.

[0014] According to one embodiment of the present invention, the pressure-resistant structure is made of a rigid material or a material with elastic deformation capability. When a material with elastic deformation capability is used, the comfort of use is better. Alternatively, a rigid material can be wrapped with a flexible material, which can ensure both pressure resistance and comfort.

[0015] Optionally, the pressure-resistant structure may be partially or completely installed in the gas channel. When partially installed, it may be installed only at pressure-prone areas, such as the back.

[0016] The beneficial effects of this invention are that, by setting up an anti-pressure structure, when the blanket is subjected to pressure, the local gas channels will not be completely blocked, and some gas channels can still be retained to allow gas to pass through, thereby improving the problem of airflow obstruction when under pressure, improving thermal efficiency, and ensuring the heating effect of the blanket; compared with existing blankets without anti-pressure function, there is no need to restrict the patient's posture or body shape in order to ensure gas conduction, thus ensuring comfort during use. Attached Figure Description

[0017] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0018] Figure 1 A schematic diagram of the layered structure of a medical heating blanket;

[0019] Figure 2 This is a schematic diagram of the planar structure of a medical heating blanket. Detailed Implementation

[0020] The following description is only intended to disclose the present invention so that those skilled in the art can implement it. The embodiments in the following description are merely examples, and those skilled in the art will conceive of other obvious modifications. The basic principles of the present invention defined in the following description can be applied to other embodiments, modifications, improvements, equivalents, and other solutions that do not depart from the spirit and scope of the present invention.

[0021] A type of medical heating blanket, such as Figure 1 It includes a breathable layer 1, an air barrier layer 2, and a pressure-resistant structure 3.

[0022] Both the breathable layer 1 and the gas barrier layer 2 are flexible layers. There is a gas channel 4 between the breathable layer 1 and the gas barrier layer 2. The gas channel 4 is generally connected to the interface. After the host is connected to the interface, the heated airflow generated by the host enters the gas channel 4. The gas channel 4 is used to allow the hot airflow generated by the host to circulate.

[0023] The pressure-resistant structure 3 is set between the breathable layer 1 and the gas barrier layer 2. It can be set only in some areas or in all areas of the gas channel 4. The pressure-resistant structure 3 is preferably installed on the gas barrier layer 2 or integrally formed with the gas barrier layer 2.

[0024] When not under pressure, the height of the gas channel 4 is preferably higher than the height of the pressure-resistant structure 3, which has higher ventilation efficiency and thus improves the heating effect.

[0025] When the gas channel is compressed, the pressure-resistant structure 3 supports the breathable layer 1 and the air-blocking layer 2, preventing the breathable layer 1 and the air-blocking layer 2 from coming into complete contact after being compressed, thus preventing the air passage from being blocked. This preserves at least part of the gas channel 4, improves the problem of air passage obstruction when compressed, improves thermal efficiency, ensures the heating effect of the blanket, and the human body and the blanket are in closer contact at the compressed position, so that the heating airflow directly acts on the core of the human body, resulting in better heating efficiency.

[0026] This solution has a simple structure, low blanket weight, low cost, and high comfort.

[0027] like Figure 1 The pressure-resistant structure 3 adopts a strip structure and has several strips of varying lengths, which can be adjusted according to the installation position. Passages 5 are formed between adjacent strip structures, and adjacent passages 5 are interconnected, such as "well" or "mouth" shaped interconnected passages, which allows gas to pass through in both the horizontal and vertical directions of passages 5, ensuring the flow efficiency of gas after being pressurized.

[0028] In other embodiments, the pressure-resistant structure 3 can also be a dotted structure, and the pressure-resistant effect can be achieved by setting a number of dotted structures.

[0029] The pressure-bearing side of the pressure-resistant structure 3 is a non-flat structure. When the pressure causes the breathable layer 1 to come into contact with the pressure-resistant structure 3, it can retain more space for gas flow. In this embodiment, the cross-section of the pressure-resistant structure 3 is concave or convex.

[0030] The pressure-resistant structure 3 can be made of rigid material or material with elastic deformation capability. It can also be made of rigid material covered with flexible material, which can ensure both pressure resistance and comfort. It can be adapted to the required pressure resistance.

[0031] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the accompanying drawings are merely examples and do not limit the present invention. The purpose of the present invention has been fully and effectively achieved. The functional and structural principles of the present invention have been shown and explained in the embodiments. Without departing from the stated principles, the implementation of the present invention may have any variations and modifications.
