Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of medical equipment, and particularly relates to a novel tracheotomy continuous humidification automatic liquid stop and anti-reflux device. Background Technique
[0002] Critical and severe patients lack the ability of independent breathing, and throat and maxillofacial surgeries will affect respiratory function. To ensure unobstructed breathing, tracheotomy can be adopted. This solution can correct the pulmonary ventilation state and reduce lung injury. However, the tracheotomy state will increase the evaporation of respiratory tract moisture, resulting in thick sputum that is difficult to cough out. Therefore, airway humidification is required, and continuous humidification or intermittent humidification is carried out according to the sputum condition. Currently, the methods of adding airway humidification fluid are as follows: 1. Intermittently open the humidification tank and add humidification water into the humidification tank; 2. Connect an infusion set to the humidification water, cut off and discard the front-end needle of the infusion set with a sterile scissors, insert the remaining head end of the infusion set into the small opening end of the tracheotomy mask, stretch it down into the oxygen atomization tank, and fix it with adhesive tape. Regularly open the infusion regulator to add humidification water. Both methods have disadvantages. First, the continuity of humidification cannot be guaranteed, and repeated opening is likely to cause contamination. Second, the connection of the infusion set is not tight and is prone to detachment. In addition, both methods cannot avoid the reverse flow of humidification water into the trachea, causing aspiration in patients. Therefore, in the prior art, the tracheotomy continuous humidification device cannot continuously maintain humidification, and it is necessary for staff to manually inject water into the humidification tank, which increases the labor intensity of the staff, increases the chance of contamination, and increases the occurrence times of patient aspiration. Content of the Utility Model
[0003] The utility model aims to solve the technical problem that the existing tracheotomy humidification device cannot supply water continuously, and provides a new type of tracheotomy continuous humidification automatic liquid stop and anti-backflow device, which includes a bottle body for holding water, and a water atomization mechanism is arranged in the bottle body. The water atomization mechanism can atomize water to facilitate humidifying the oxygen entering the bottle. A cover body is detachably arranged at the top of the bottle body, and the cover body is threadedly connected with the bottle body. An oxygen inlet is arranged on one side of the cover body, and the oxygen inlet is connected to an oxygen supply machine through a pipeline. An oxygen outlet is arranged at the top of the cover body, and an anti-backflow oxygen supply pipe is arranged between the oxygen outlet and a breathing mask. An inlet for water is arranged at the top of the cover body. The oxygen supply pipe includes a telescopic connecting inner pipe, an upper joint is arranged at the upper end of the connecting inner pipe, a lower joint is arranged at the lower end of the connecting inner pipe, a connecting outer pipe is sleeved outside the connecting inner pipe, the top end of the connecting outer pipe is fixed to the lower end of the upper joint, and the lower end of the connecting outer pipe is fixed to the top end of the lower joint. A chamber for water supply to flow is formed between the connecting inner pipe and the connecting outer pipe; a plurality of liquid outlet holes for discharging liquid are opened at the lower end of the connecting inner pipe, and the liquid outlet holes are spaced from top to bottom along the connecting inner pipe. Both the connecting inner pipe and the connecting outer pipe are made of telescopic threaded hoses. When the water in the bottle body flows back along the connecting inner pipe, when the water flows to the liquid outlet holes on the connecting inner pipe, the water flows into the chamber between the connecting inner pipe and the connecting outer pipe through the liquid outlet holes, and then flows back into the bottle body through the liquid leakage holes at the lower end of the connecting inner pipe under the action of gravity. The inlet for water is detachably and fixedly connected to the lower end of an infusion set, the bottom end of the infusion tube extends downward into the bottle body, and a fully automatic float valve (working principle: when the water surface drops, the floating ball drops, and the pressure of the water in the water pipe is used to open the sealed silicone plunger in the valve body, and the valve body opens to supply water; when the water surface rises, the floating ball floats up, and the connecting rod drives the sealed silicone plunger to block the water inlet hole, and the valve body stops supplying water) is arranged at the upper end inside the bottle body. The fully automatic float valve is connected to the bottom end of the infusion tube. When the water surface in the bottle body drops, the fully automatic float valve opens, and the water in the infusion tube flows into the bottle body. As the liquid level in the bottle body rises to a certain position, the fully automatic float valve blocks the water from continuing to flow into the bottle body.
[0004] Preferably, the total length of each liquid outlet hole is equal to the circumference of the connecting inner pipe, which can ensure that when the bottle body is tilted, the water flowing back into the oxygen supply pipe flows back into the bottle body.
[0005] Preferably, both the connecting inner pipe and the connecting outer pipe are made of telescopic threaded hoses and can be bent at a certain angle.
[0006] Preferably, the bottle body is made of a transparent material, and a liquid level line for facilitating the observation of the liquid level is arranged on the outer side of the bottle body.
[0007] Preferably, an infusion switch for controlling the on-off of the water supply is arranged on the infusion tube.
[0008] Preferably, the inlet for water is detachably and fixedly connected to the lower end of the infusion set.
[0009] Preferably, a fully automatic float valve is arranged at the upper end inside the bottle body to automatically stop and release the liquid.
[0010] The adoption of the above solution has the following advantages:
[0011] The provision of the oxygen supply pipe. When water flows to the liquid outlet holes on the connecting inner pipe, the water flows into the chamber between the connecting inner pipe and the connecting outer pipe through the liquid outlet holes, and then flows back into the bottle body again through the liquid leakage holes at the lower end of the connecting inner pipe under the action of gravity, which can prevent the water in the bottle body from flowing back into the breathing mask; the provision of the fully automatic float ball valve can control the on-off of the water in the infusion tube according to the water surface height in the bottle body, control the continuous water supply to the bottle body in the infusion bag, replace manual water supply to the bottle body, and save manpower; the cover body is threadedly connected with the infusion device, and the connection is tighter and convenient for disassembly and assembly.
