Description

Technical Field

[0001] The utility model relates to the technical field of heat preservation bags, in particular to a low-temperature heat preservation bag with visible temperature. Background Art

[0002] During brain surgery, low-temperature ice saline is usually injected into the patient's brain through the femoral artery sheath to cool and protect brain tissue. The low-temperature ice saline is placed in an insulation bag for insulation, so that the ice saline remains at a low temperature for injection.

[0003] Although existing thermal insulation bags can keep the body warm, the temperature of the ice saline solution will gradually increase over time. However, the injection of ice saline solution needs to be maintained at 4°C for optimal effect. However, current thermal insulation bags cannot detect internal temperature changes, making it difficult to cool the temperature inside. As a result, the temperature of the ice saline solution increases over time, reducing its brain tissue protective effect.

[0004] Currently, no effective solutions have been proposed for the problems in related technologies. Utility Model Content

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] As introduced in the background technology, there are deficiencies in the existing technology. In order to solve the above technical problems, this application proposes a low-temperature insulation bag with visible temperature.

[0023] See also Figures 1-6 A low-temperature insulation bag with visible temperature includes an insulation bag main body 1, an insulation layer 101 is provided inside the insulation bag main body 1, a temperature display screen 102 and an alarm 104 are fixedly installed on the front end of the insulation bag main body 1, a temperature sensor 103 is fixedly installed on the inner wall of the insulation bag main body 1, the temperature sensor 103 is electrically connected to the temperature display screen 102 and the alarm 104, and the temperature display screen 102 and the alarm 104 are electrically connected to a controller, a circular hole 105 is opened at the rear end of the insulation bag main body 1, a cooling block 106 is installed inside the circular hole 105 by threaded rotation, and a sealing plug 107 is installed at the rear end of the cooling block 106 by threaded rotation.

[0024] Specifically, ice salt water is placed inside the insulation bag body 1 and is insulated by the insulation layer 101. The temperature inside the insulation bag body 1 is sensed by the temperature sensor 103 (the model of the temperature sensor 103 is NTC, which is a prior art. The connection relationship between the temperature sensor 103 and the temperature display screen 102 is an existing and simple circuit control technology. The temperature sensor 103 transmits the detection data to the temperature display screen 102 for display. It is common knowledge for those skilled in the art and will not be described in detail here). The sensed temperature is displayed on the temperature display screen 102, which is convenient for medical staff to observe the temperature changes inside the insulation bag body 1. When the temperature of the ice salt water rises, the temperature display screen 102 transmits a signal to the controller, and an alarm is sounded through the alarm 104. The medical staff adds dry ice to the inside of the cooling block 106, seals it with the sealing plug 107, and then rotates the cooling block 106 to install it on the rear end of the insulation bag body 1, thereby cooling the inside of the insulation bag body 1, avoiding the temperature increase of the ice salt water after long-term use, which leads to a reduction in the protective effect on brain tissue.

[0025] Furthermore, an infusion tube 108 is fixedly installed at the bottom of the heat preservation bag body 1, and a connecting tube 109 is connected to the bottom of the heat preservation bag body 1 through the infusion tube 108, and an infusion needle 110 is fixedly installed on the top of the connecting tube 109;

[0026] Furthermore, a protective sleeve 111 is fixedly mounted on the rear end of the inner wall of the heat preservation bag body 1, and the infusion needle 110 can extend into the interior of the protective sleeve 111;

[0027] Specifically, after the ice saline bag is placed inside the insulation bag body 1 for insulation, the medical staff inserts the infusion needle 110 into the ice saline bag and injects the ice saline through the infusion tube 108 and the connecting tube 109. When the infusion needle 110 is not in use, it is inserted into the protective cover 111 for protection, so as to prevent the protective cover 111 from being easily bent due to collision and compression, and at the same time prevent the infusion needle 110 from scratching the insulation bag body 1 and reducing its insulation effect.

[0028] Furthermore, a sealing mechanism 2 is provided on the top of the heat-insulating bag body 1. Sealing blocks 201 are fixedly installed at the front and rear ends of the top of the heat-insulating bag body 1. Rotating rods 202 are rotatably installed on both sides of the inner side of the rear end sealing block 201. Limiting grooves 203 are provided on both sides of the front end sealing block 201. Through grooves 204 are provided at the top and bottom of the limiting grooves 203. A limiting block 205 is fixedly installed at the front end of the rotating rod 202. The limiting block 205 passes through the through groove 204 and extends to the front end of the limiting groove 203.

[0029] Furthermore, a groove is formed at the bottom of the inner side of the sealing block 201, and a sealing strip 206 is fixedly installed inside the groove at the bottom of the sealing block 201;

[0030] Specifically, after the ice salt water is placed inside the insulation bag body 1, the sealing block 201 is closed, and then the limiting block 205 at the front end of the rotating rod 202 passes through the through slot 204 in a vertical state and extends to the front end of the limiting slot 203. Then, the limiting block 205 is rotated to a horizontal state so that the limiting block 205 limits the sealing block 201, thereby sealing the opening at the top of the insulation bag body 1 through the sealing strip 206, thereby preventing the insulation effect of the insulation bag body 1 from being reduced.

[0031] Furthermore, a fixing block 112 is fixedly installed on the top of the sealing block 201, a hanging hole 113 is opened through the interior of the fixing block 112, and a hook 114 is fixedly installed on the top of the inner wall of the insulation bag body 1;

[0032] Specifically, the hanging hole 113 is used to conveniently hang the insulation bag body 1 for infusion, and the hook 114 is used to conveniently hang the ice saline bag inside the insulation bag body 1, which is convenient for medical staff to operate.

[0033] Working principle: First, the medical staff puts the ice saline bag into the insulation bag body 1 through the opening at the top of the insulation bag body 1, hangs the ice saline bag through the hook 114, closes the sealing block 201, keeps the limit block 205 at the front end of the rotating rod 202 in a vertical state, passes through the through slot 204 and extends to the front end of the limit slot 203, and then rotates the limit block 205 to a horizontal state to limit the sealing block 201, so that the top of the insulation bag body 1 is fixed and closed, and then inserts the infusion needle 110 through the bottom of the ice saline bag for infusion, and the temperature is adjusted. The sensor 103 monitors the temperature inside the thermal insulation bag body 1 and displays the temperature inside the thermal insulation bag body 1 through the temperature display screen 102. If the temperature inside the thermal insulation bag body 1 rises, the temperature display screen 102 transmits a signal to the controller to control the alarm 104 to sound an alarm. Then the medical staff removes the cooling block 106 and adds dry ice, and then seals the opening with the sealing plug 107 and installs the cooling block 106 inside the circular hole 105 by threaded rotation, thereby cooling the inside of the thermal insulation bag body 1 so that the ice salt water is always maintained at 4°C.

[0034] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
