Description

Technical Field

[0001] The utility model belongs to the technical field of inflatable helmets, in particular to an inflatable protective helmet. Background Art

[0002] The inflatable helmet is specially designed for patients who have no endurance for activities and cannot change their body position on their own and who are bedridden for a long time / using ice caps for hypothermia treatment. When the patient wears it and then lies flat in bed, he or she can feel relatively comfortable.

[0003] In the process of realizing the utility model, the inventors found that there are at least the following problems in this technology: However, the current inflatable helmets usually only have the basic functions of a helmet, and some of these special patients cannot actively express the comfort of their heads when they are bedridden for a long time. Sometimes, because the patient's head is stuffy in the helmet for a long time or the helmet exerts too much pressure on the head, it leads to high head temperature or discomfort due to squeezing.

[0004] For this reason, we propose a kind of inflatable protective helmet to solve the above-mentioned problems. Utility Model Content

[0005] The main purpose of the utility model is to provide an inflatable protective helmet, which is easy to adjust when the temperature or air pressure is not suitable, so that the patient can get a better experience and can effectively solve the problems in the background technology.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] An inflatable protective helmet comprises an outer protective skin and an air bag fixedly bonded to the inner side of the outer protective skin, a receiving cavity for receiving a patient's head is formed on the inner side of the air bag, the interior of the air bag is of hollow design, an inflatable tube passing through the outer protective skin and extending to the outside of the outer protective skin is fixedly connected to one side wall of the air bag, and an extension tube is screwed on the opening of the inflatable tube on the side facing away from the air bag;

[0008] An extension tube is integrally connected to the side of the extension tube facing away from the inflation tube, a barometer and a temperature sensor are fixed in the inner cavity of the extension tube, a display screen and a controller are fixed outside the extension tube, and the barometer, temperature sensor and display screen are all electrically connected to the controller.

[0009] As a preferred embodiment, the airbag is filled with gas and has a tendency to expand outward, so that the airbag can cushion the patient's head and prevent pressure injuries to the patient's head.

[0010] As a preferred embodiment, the inner wall of the inflation tube facing away from the airbag is provided with an internal thread, and the outer wall of the extension tube is provided with an external thread, and the internal thread of the inflation tube is adapted to the external thread of the extension tube; thereby facilitating the connection between the inflation tube and the extension tube without air leakage between the two.

[0011] As a preferred embodiment, an inner mounting plate is fixedly bonded to the side of the inner cavity of the expansion tube facing away from the inflation tube, wherein the barometer and the temperature sensor are both mounted on the inner mounting plate, so that the structures of the barometer and the temperature sensor remain stable.

[0012] As a preferred embodiment, an external mounting plate is fixedly bonded to the outer wall of the extension tube, wherein the external mounting plate fits tightly with the extension tube, and the display screen and the controller are both mounted on the external mounting plate, so that both the controller and the display screen remain stable.

[0013] As a preferred embodiment, a protective cover is fixedly bonded to the external mounting plate, wherein the controller is located inside the protective cover, so that the protective cover can protect the controller.

[0014] In summary, the technical effects and advantages of the utility model are as follows:

[0015] The inflatable protective helmet, through the function of the extension tube, does not affect the body sensation of the patient's head when lying in bed, and can use the temperature sensor and barometer to detect the temperature and air pressure in the airbag, so as to adjust it when the temperature or air pressure is not suitable, so that the patient can get a better experience;

[0016] The inflatable protective helmet injects a sufficient amount of gas into the airbag through the inflation tube, and then screws the extension tube onto the opening of the inflation tube on the side facing away from the airbag, so that the extension tube and the expansion tube remain stable. When wearing the helmet, the patient simply inserts his head into the accommodating cavity and makes full contact with the inner wall of the accommodating cavity. Since the airbag is full of gas and has a tendency to expand outward, it is easy to play a role of buffering and protection. BRIEF DESCRIPTION OF THE DRAWINGS
