Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of medical treatment, in particular to a heating sleeve self-circulation device. Background Art
[0002] In modern clinical medicine, ventilators, as an effective means of artificially replacing spontaneous ventilation functions, have been widely used in respiratory failure caused by various reasons, anesthesia respiratory management during major surgery, respiratory support therapy and emergency resuscitation. They occupy a very important position in the field of modern medicine. Ventilators are a vital medical device that can prevent and treat respiratory failure, reduce complications, save and prolong patients' lives. During the use of ventilators, due to the inconsistency between the indoor temperature and the temperature in the human body, the exhaled gas will form water droplets in the breathing tube. The formed water droplets will affect the patient's use, so medical staff will add a heating sleeve to the breathing tube during use.
[0003] A heating sleeve for a ventilator trachea disclosed in the Chinese utility model patent application disclosure specification CN209270540U, although the utility model can directly put the heating sleeve body on the breathing tube through the combined action of the slot and the block, not only will the strap not loosen during use, but it also saves space and is simple and convenient to operate. The setting of the insulation layer slows down the heat dissipation rate of the heating pipe to the outside, ensures the insulation effect of the heating pipe, and saves the electrical resources wasted during heating. In addition, the setting of the fixing belt supports and fixes the heating pipe, and will not affect the patient's use due to the weight of the breathing tube, thereby ensuring the safety of the heating pipe when in use. However, a heating wire is provided inside the heating sleeve, and the heating sleeve is glued to the breathing tube by Velcro, which will cause the local temperature of the heating sleeve to be too high, which may easily cause local overheating of the breathing tube, and has the disadvantage of poor heating effect. Moreover, the connection is poorly stable due to the Velcro. Utility Model Content

[0013] The utility model provides a heating sleeve self-circulation device, which has the following beneficial effects:
[0014] 1. This heating sleeve self-circulation device, through the arrangement of the heating sleeve body, the convex connecting block, the concave connecting block, the first sealing gasket, the second sealing gasket, the water pump, the water inlet pipe, the clamping block, the clamping groove, the push rod, the return pipe and the heating box, enables the heating sleeve self-circulation device to have the effect of uniformly heating the breathing gas. When in use, the breathing gas generated by the ventilator passes through the breathing tube. In order to avoid the temperature difference between the breathing gas and the room temperature being too large, and the moisture in the gas condensing to produce water droplets, the staff will put the heating sleeve body on the breathing tube. During the installation process, the two ends of the heating sleeve body are separated, and the breathing tube is inserted into the inner side of the heating sleeve body, and then the convex connecting block at one end of the heating sleeve body is inserted into the concave connecting block at the other end. The inner side of the block, the sizes of the convex connecting block and the concave connecting block match each other. When the protruding end of the convex connecting block enters the inner side of the concave connecting block, the blocking block on the side of the convex connecting block moves to the corner of the upper end of the concave connecting block, the blocking block is squeezed and squeezed into the groove. When the protruding end of the convex connecting block completely enters the concave connecting block, the position of the blocking block is relative to the blocking groove, and the first spring releases the elastic potential energy, so that the blocking block is stuck in the blocking groove, completing the fixation of the convex connecting block and the concave connecting block. When the protruding end of the convex connecting block is completely pressed into the inner side of the concave connecting block, the first sealing gasket and the second sealing gasket squeeze each other to form a seal at the connection. After connecting the two ends of the heating sleeve body, the heating wire is controlled by the heater to work, and the current passes through the heating The wire generates a large amount of heat under the action of the resistance, which in turn heats the liquid in the heating box, so that the liquid in the heating box reaches a certain temperature and maintains it. The liquid in the heating box is pumped into the water inlet pipe through a water pump, and the liquid enters the heating sleeve body through the water inlet pipe. After the liquid enters the heating sleeve body, it disperses to both sides. The liquid on the right moves upward through the through groove opened at the connection between the convex connecting block and the concave connecting block, and the liquid on the left moves directly upward until the heating sleeve body is filled. Under the action of pressure, the liquid returns to the heating box through the return pipe, which plays a role in automatically circulating the heated liquid. The heated liquid heats the breathing tube through heat transfer in the heating sleeve body, thereby heating the gas passing through the breathing tube. When the heating sleeve body is not needed, the staff presses the pressure block inward at the same time to make the push rod slide inward in the card slot, and pushes out the card block stuck in the card slot through the push rod. After the card block is out of the card slot, the convex connecting block and the concave connecting block can be easily separated, and then the heating sleeve body can be opened and removed, which facilitates installation. The device circulates the liquid in the heating sleeve body and keeps the liquid at the same temperature through the heater and the heating wire, thereby uniformly heating the gas passing through the breathing tube, keeping the gas breathed by the patient at the same temperature, and achieving the purpose of improving the heating effect and convenience of use.

A heater 19 is installed on the outer surface of the heating box 18, and a heating wire 20 is installed inside the heating box 18. The heater 19 is electrically connected to the heating wire 20 through a wire, and the controller 21 is electrically connected to the water pump 8 through a wire.

When in use, the breathing gas generated by the ventilator passes through the breathing tube 1. In order to avoid the temperature difference between the breathing gas and the room temperature being too large, and the moisture in the gas condensing to produce water droplets, the staff will set the heating sleeve body 2 on the breathing tube 1. During the installation process, the two ends of the heating sleeve body 2 are separated so that the breathing tube 1 is clamped into the heating sleeve body 2.
