Description

Technical Field

[0001] This invention relates to the field of cooling devices, and more particularly to an emergency extracorporeal cooling device. Background Technology

[0002] Fever is a common symptom in the emergency department. When a person has a fever, their body temperature is high. However, excessively high body temperature or prolonged fever can affect health and cause serious consequences.

[0003] When a person has a fever, emergency treatment usually involves medication or physical cooling methods. When using physical cooling, medical staff typically apply ice packs or fever-reducing patches directly to the patient. However, these two types of physical cooling items cannot be stably fixed to the patient's body. When the patient is uncomfortable due to the fever, they are easily removed. Moreover, the temperature of these two types of physical cooling items will also increase with the patient's temperature, resulting in a short cooling effect.

[0004] Therefore, in view of the above-mentioned problems that patients are prone to moving around due to fever, and that it is difficult to fix external cooling devices to the patient, as well as the short cooling time of existing external cooling devices, an emergency external cooling device can be designed. Summary of the Invention

[0005] To overcome the problems of patients being prone to movement due to fever, making it difficult to fix external cooling devices in place, and the short cooling time of existing external cooling devices.

[0006] The technical solution of this invention is as follows: an emergency external cooling device, comprising a bed board, a restraint plate assembly, a soft pad for the torso area, a soft pad for the head area, a cooling pipe, a cooling water tank, a water tank inlet and outlet pipe assembly, a head cooling assembly, and a torso cooling assembly; a restraint plate assembly for restricting the movement of a feverish patient after lying down is installed on the rear side of the upper end of the bed board; the restraint plate assembly includes a first restraint plate, a second restraint plate, a push cylinder assembly, and a cooling fan; a push cylinder assembly is installed on the outer side of the first and second restraint plates; a cooling fan is fixedly connected to the inner side of the first restraint plate; a soft pad for the torso area is fixedly connected to the rear side of the upper end of the bed board; a soft pad for the head area is fixedly connected to the front side of the upper end of the bed board; a cooling water tank for cooling the circulating water is fixedly connected to the lower end of the bed board; a cooling pipe for cooling the back of the feverish patient is fixedly connected to the upper end of the soft pad for the torso area; a head cooling assembly for fixing and cooling the head of the feverish patient is installed on the upper end of the soft pad for the head area; The cooling components and the cooling pipe circulation water inlet and outlet ends are equipped with water tank inlet and outlet pipe assemblies; the water tank inlet and outlet pipe assemblies are connected to the cooling water tank; the head cooling component includes a cooling water pillow, a damping elastic component assembly, a pressure plate, and a cooling contact area; a pressure plate is set at the front end of the cooling water pillow; the pressure plate and the bed board are elastically supported by symmetrical damping elastic component assemblies; a cavity for water storage is opened on the inner side of the pressure plate; a cooling contact area for contacting the forehead of the feverish patient is set at the lower end of the pressure plate; a torso cooling component for continuously wiping alcohol onto the torso of the feverish patient is installed at the rear end of the limiting plate assembly; the torso cooling component includes an alcohol storage tank, a nozzle, an alcohol application roller, positioning holes, positioning posts, and rotating parts; a nozzle for extracting and spraying alcohol is installed at the front end of the alcohol storage tank; the nozzle and spray pipe are designed to be inclined upwards; an alcohol application roller is set at the upper end of the nozzle; positioning holes are opened on the left and right sides of the alcohol application roller; a positioning post is slidably connected to the inner side of the positioning hole; a rotating part is installed at the left end of the positioning post.

[0007] Preferably, in the first step, the feverish patient takes off his / her outer clothes and lies on the bed board, lying flat with the soft pads in the direction of the torso area and the head area. The cooling water pillow is placed under the neck of the feverish patient, and the head is fixed by the pressure plate supported by the damping elastic component group. The cooling contact area is in contact with the patient's forehead. In the second step, the first and second limiting plates of the limiting plate assembly are pushed and closed by the cylinder group. The first and second limiting plates can restrict the feverish patient from moving around randomly after lying down, and turn on the cooling fan to accelerate the air circulation in the internal limiting space. The third step is to start the cooling water tank at the bottom of the bed board to cool the internal circulating water. The cooling water tank serves as the cold source for the three water-using components. Through the water tank inlet and outlet pipe group, it can supply the cooling pipes of the torso area cushion, as well as the cooling water pillow and pressure plate cavity of the head cooling component. The fourth step involves cooling tubes in the torso area padding to cool the back of the feverish patient. The torso cooling component uses an alcohol applicator roller that moves back and forth to apply alcohol to the patient's chest, hands, and legs. After one application cycle, the alcohol applicator roller resets, and the nozzle draws alcohol from the alcohol storage tank and sprays it onto the alcohol applicator roller, replenishing it with new alcohol for another application to the patient.

[0010] Preferably, the alcohol storage box has viewing windows with graduation markings at both the front and rear ends; the top of the alcohol storage box has an inlet for filling with alcohol.

[0011] Preferably, there are three positioning holes distributed along the triangle point; there are three positioning posts distributed along the triangle point; the positioning holes and positioning posts are in one-to-one correspondence; the alcohol applicator roller and the rotating part adopt a detachable structure, which is mainly connected by the positioning holes and positioning posts between them, ensuring cleanliness and hygiene during cooling.

[0012] Preferably, the four corners of the lower end of the bed board are fixedly connected with legs; the height of the legs is greater than the height of the cooling water tank; and the lower end of the legs is equipped with anti-slip pads, so it can be used as a flatbed.

[0013] Preferably, the bed board has symmetrical left and right limiting storage slots at both the front and rear ends; a lifting rod is slidably connected inside the limiting storage slot; the handle area of ​​the lifting rod is equipped with an anti-slip sleeve, so it can be used as a stretcher.

[0014] The beneficial effects of this invention are: Compared to traditional methods of physical cooling by applying ice packs or fever-reducing patches, this invention restricts the movement of feverish patients while they lie down using a limiting component. A cooling fan accelerates airflow within the confined space. A cooling water tank cools the circulating water, supplying it to the cooling pipes of the torso area's padding and the cooling water pillow and pressure plate cavity of the head cooling component. This allows for water-cooling of the patient's back, head, and neck, effectively removing heat from the body surface and helping to quickly lower body temperature and alleviate fever discomfort. The water-cooling contact area is large. Simultaneously, alcohol is applied to the patient's chest, hands, and legs using a moving alcohol applicator roller. After one application cycle, the alcohol applicator roller resets, and the nozzle draws alcohol from the alcohol storage tank and sprays it onto the roller, refilling it with new alcohol for another application. This invention provides a longer cooling duration, reduces potential side effects or allergic reactions from medications, and is highly automated, making it ideal for emergency use.

[0021] Please see Figure 6 In this embodiment, the four corners of the lower end of the bed board 1 are fixedly connected with support legs 12; the height of the support legs 12 is greater than the height of the cooling water tank 6; the lower end of the support legs 12 is provided with anti-slip pads, so that it can be used as a flat bed; the front and rear ends of the bed board 1 are provided with left and right symmetrical limiting storage grooves 10; the inner side of the limiting storage grooves 10 is slidably connected with lifting rods 11; the handhold area of ​​the lifting rods 11 is provided with anti-slip sleeves, so that it can be used as a stretcher.

[0022] When performing the procedure, the first step is for the feverish patient to remove their outer clothing and lie flat on the bed board 1, with the soft pads 3 for the torso area and 4 for the head area. The cooling water pillow 801 is placed under the patient's neck, and the head is fixed by the pressure plate 803 supported by the damping elastic component group 802. The cooling contact area 804 is in contact with the patient's forehead.

[0023] In the second step, the first limiting plate 201 and the second limiting plate 202 of the limiting plate assembly are pushed and closed by the cylinder group 203. The first limiting plate 201 and the second limiting plate 202 can restrict the feverish patient from moving around randomly after lying down, and turn on the cooling fan 205 to accelerate the air circulation in the internal limiting space.

The cooling water tank 6 cools the circulating water inside and supplies it to the cooling pipes 5 of the soft pad 3 in the torso area, as well as the cooling water pillow 801 and the cavity of the pressure plate 803 in the head cooling component. In this way, the back, head, and neck of the lying patient can be cooled by water, effectively removing heat from the body surface, helping to quickly lower body temperature and relieve the discomfort caused by fever. The water cooling contact area is large. At the same time, the patient's chest area, hands, and legs are all coated with alcohol by the back-and-forth moving alcohol application roller. After one application cycle, the alcohol application roller 903 is reset, and the nozzle 902 draws alcohol from the alcohol storage tank 901 and sprays it onto the alcohol application roller 903, allowing the alcohol application roller 903 to be replenished with new alcohol and applied to the patient again. The cooling device of the present invention has a long duration, reduces the possible side effects or allergic reactions of drugs, and has a high degree of automation, making it very suitable for use in the emergency room.
