Description

Technical Field

[0001] The invention belongs to the technical field of medical devices, and in particular relates to a rapid composite cooling device for emergency heatstroke. Background Art

[0002] Prolonged exposure to high temperature and high humidity can lead to heat stroke, which is a central nervous system disorder caused by dysfunction of the body's temperature regulation center, failure of sweat gland function, and excessive loss of water and electrolytes. During heat stroke, due to the disorder of the body's temperature regulation function, excessive heat accumulation in the body may cause a series of central nervous system symptoms. Mild heat stroke may manifest as headache, dizziness, flushed face, thirst, etc., while severe heat stroke may cause serious conditions such as heat cramps, heat exhaustion and heat stroke. Among them, heat stroke is the most serious type of heat stroke, manifested by high fever, dry skin, no sweating, impaired consciousness, etc., which may lead to multiple organ failure and even death. It is very dangerous.

[0003] For patients with severe heatstroke and heat stroke, the most important treatment method is to immediately cool down the body. Currently, the main methods and devices for cooling the body include ice blanket cooling, rapid infusion of cold saline, CRRT cooling, and injection of ice saline through a gastric tube and rectum. However, there is an important problem that the cooling method is single and the cooling speed is slow. The operation, infusion, establishment of intravenous access, and ice blanket cooling require time, which is far from meeting the requirement of reducing the patient's body temperature to around 37 degrees within 30 minutes to 1 hour. Moreover, these treatments must be performed in the emergency room / intensive care unit, which greatly prolongs the time for patients to start cooling, resulting in extremely poor prognosis for heat stroke patients. Most patients will have persistent multi-organ dysfunction, disability or death. Slow cooling speed, long preparation time, and high treatment conditions are the key to restricting the treatment of heat stroke. With the intensification of global warming, future war training and field training will lead to an increase in the occurrence of heat stroke. The current rescue model is prone to exceed the optimal cooling time, and it is a pity that the role of first witnesses, 120 and other pre-hospital emergency personnel cannot be maximized.

[0004] Therefore, a non-invasive rapid composite cooling device for emergency heatstroke is needed to solve the above technical problems. Summary of the invention

DETAILED DESCRIPTION

[0023] Example 1

[0024] A rapid composite cooling device for emergency heatstroke, comprising: a fixing plate 1, an electric cooling blanket 2, and a cover plate 3; the fixing plate 1 is a concave structure, the upper end of the fixing plate 1 is detachably mounted with the electric cooling blanket 2, and the upper part of the fixing plate 1 is detachably mounted with the cover plate 3;

[0025] The electric cooling blanket 2 is made according to the structure of the human body. A leg cooling unit 21 is fixedly installed on the thigh part of the upper end of the electric cooling blanket 2, an arm cooling unit 22 is fixedly installed on the upper end of the arm part, and a neck cooling unit 23 is fixedly installed on the upper end of the neck part; a chest cooling unit 210 is fixedly installed on the upper end of the chest part; the neck cooling unit 23 and the chest cooling unit 210 are openly arranged and fixed by a Velcro band 2101 arranged on the neck cooling unit 23 and the chest cooling unit 210; air outlet holes 24 are opened on different cooling units; different cooling units have the same structure, and are composed of a fixing belt 211 and an air bag 212, and the fixing belt 211 is wrapped on the outer side of the air bag 212 and fixedly installed on the electric cooling blanket 2; the human body is rapidly and non-invasively cooled by the cooling units arranged at different parts; by performing cooling at different parts of the human body rich in aortas, non-invasive and rapid cooling of the human body can be achieved;

[0026] At the same time, in the present embodiment, each cold compress unit is composed of an airbag 212 and a fixing belt 211, and the fixing belt 211 is a plastic fixing belt 211; the fixing belt 211 is plastic, and the plastic fixing belt 211 is used as an external support to relatively limit the airbag 212, and at the same time, by inflating the airbag 212, the airbag 212 can be expanded inward, so that it can tightly wrap the relevant parts of the person suffering from heatstroke, thereby increasing the effect of cold compress; in addition, the fixing belt 211 can also be an elastic fixing belt 211, and the elastic fixing belt 211 does not have a limiting effect on the airbag 212. After the airbag 212 is expanded, it will support the fixing belt 211 outward and also form a supporting effect on the arm, but due to the existence of the arm part, its wrapping effect on the arm is not as good as the plastic fixing belt 211; therefore, it is better for the fixing belt 211 to be a plastic fixing belt 211.

[0027] Example 2

[0028] In this embodiment, the leg cold compress unit 21, the arm cold compress unit 22, the neck cold compress unit 23, and the chest cold compress unit 210 are interconnected, and the interconnection method can be through a pipeline from the inside or outside of the electric cooling blanket 2 (not shown in the figure), and the best method is through the internal connection method; at the same time, the neck cold compress unit 23 is provided with an air supply pipe 27, and a fan 26 is fixedly connected to the air supply pipe 27, and the rear end of the fan 26 is connected to an air pump 25 through the air supply pipe 27; the external cold air is extracted by the air pump 25, and the flow rate is further increased by the fan 26; thereby, the cold air can be input to The position of the airbag 212 is output to the outside through the air delivery hole; in addition, in this embodiment, the air pump 25 can be replaced by a cold air manufacturing device, and the cold air manufacturing device outputs cold air to the outside, and then the fan 26 delivers it; in this embodiment, the cold air manufacturing device belongs to the prior art and will not be described in detail here. In addition, in this embodiment, when using, the patient can first lie on the electric cooling blanket 2, and then the neck cold compress unit 23 and the chest cold compress unit 210 are fixed in a surrounding manner through the Velcro tape 2101, and the arm cold compress unit 22 and the thigh cold compress unit can be directly inserted by the patient's hand;

[0029] In addition, in this embodiment, in order to detect changes in the patient's body temperature, a plurality of temperature sensors 4 are arranged at the upper end of the electric cooling blanket 2. The patient's body temperature is detected by the arranged temperature sensors 4, and the detection method can be performed through a control panel or a display screen. The control panel and the display screen, as well as the connection and detection method between them and the temperature sensor 4 belong to the prior art, and the magnetic beads will not be explained in detail.

[0030] In addition, in the present embodiment, if the air outlet 24 is used alone for jetting, the cold wind blown out through the air outlet 24 on the air bag 212 will be ejected in a straight line. Although part of the wind can reach the skin surface, it is difficult to blow it relatively concentratedly, resulting in weak wind blowing effect. The method of using the air outlet 24 alone still has defects to a certain extent. Therefore, in order to solve the above technical problems, in the present embodiment, an air outlet pipe 213 is detachably installed on the air outlet 24, and the air outlet pipe 213 is in the form of a gooseneck hose, and the structure of the air outlet pipe 213 is a conical structure; firstly, the detachable form allows medical staff to install or remove it according to actual needs; the specific detachable form is a plug-in method; in addition, the material form of the air outlet pipe 213 is a gooseneck hose (that is, a plastic gooseneck hose that can change its shape, similar to the outer protective tube of a table lamp in the prior art), and the direction of the cold air inside the air outlet pipe 213 can be changed at will through the gooseneck hose; such a design can more concentratedly apply the cold air to the patient's skin surface; at the same time, the conical structure can further enhance the wind speed (Bernoulli principle), which can enhance the cooling effect.

[0031] In addition, in the present embodiment, in order to further enhance the cooling effect, a soft water pipe 29 is fixedly installed on the outer periphery of the upper end of the electric cooling blanket 2, and a plurality of water spray holes 291 are evenly opened on the upper end of the soft water pipe 29; a water pump 28 is connected to the soft water pipe 29 near the arm part; the water outside is drawn by the water pump 28, and the water is sprayed out through the water spray pipe on the soft water pipe 29, which can directly act on the patient's skin surface; at the same time, the wind blown out by the above-mentioned air outlet pipe 213 can accelerate the evaporation of water scattered on the patient's skin surface, take away the heat from the patient, and through the synergistic effect of the two, the cooling effect is enhanced so that the patient can cool down quickly.

[0032] Example 3

[0033] In this embodiment, the fixing plate 1 is rotatably installed with a hand bearing plate 11, a leg bearing plate 12, and a head bearing plate 13 according to the structure of the human body; the bearing plates of each part can be used as a supporting structure for transporting patients; it can be used as a temporary fixing plate 1 or a stretcher, and the fixing plate 1 can cooperate with the cover plate 3. Since the bearing plates of each part on the fixing plate 1 are rotatably installed, they can be directly rotated into the inside of the fixing plate 1 after rotation; then, it can be covered by the cover plate 3, and the covering can effectively prevent the electric blanket placed inside from falling dust;

[0034] In addition, in the present embodiment, a positioning block 33 is symmetrically installed at the lower end of the fixed plate 1; fixed blocks 31 are fixedly installed on the two side walls of the cover plate 3 corresponding to the positioning block 33 on the cover plate 3, and a rotating plate 32 is movably installed on the fixed block 31, and the rotating plate 32 can just reach the upper end of the positioning block 33 after rotation, and the end of the rotating plate 32 and the positioning block 33 are both magnetic, and the magnetism of the two is opposite; the mutual attraction of the magnetic force between the positioning block 33 and the rotating plate 32 can make the cover plate 3 and the fixed plate 1 relatively fixed, so as to facilitate taking and transportation.

[0035] The preferred embodiments of the present invention disclosed above are only used to help explain the present invention. The preferred embodiments do not describe all the details in detail, nor do they limit the invention to only the specific implementation methods described.
