Description

Technical Field

[0001] This utility model relates to nursing tools, and more particularly to a T-shaped tube for oxygen inhalation in tracheostomy patients with continuous slow infusion of humidifying fluid. Background Technology

[0002] To prevent airway dryness in tracheostomized patients, oxygen needs to be pre-humidified during oxygen delivery. Currently, the method of intermittently injecting humidifying fluid into the nebulizer is used. The disadvantages of this method are: (1) It requires timed and multiple fluid additions, which makes nursing work cumbersome; (2) When too much fluid is added, the humidifying fluid or oxygen after nebulization is discharged from the air outlet, causing the bed to become damp; (3) If fluid is not added in time, dry oxygen will be supplied to the patient, causing sputum to become thick and difficult to cough up, aggravating the degree of lung infection and prolonging the length of hospital stay.

[0003] In addition, the humidification solution is usually prepared by mixing sterile water and physiological saline in a 1:1 ratio, and then injected into the nebulizer. The preparation process further increases the burden on the humidification and oxygen supply work. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a T-shaped tube for oxygen inhalation of tracheostomy patients with continuous slow injection of humidifying fluid, which reduces the workload of preparing and intermittently adding fluid, and can continuously and slowly inject humidifying fluid into the jet nebulizer during oxygen delivery to tracheostomy patients, avoiding nursing problems caused by too much or too little humidifying fluid in the jet nebulizer.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a T-shaped tube for continuous slow-infusion of humidifying fluid for tracheostomy patients, comprising a jet-type nebulizer chamber, the bottom of which is connected to an oxygen source via an oxygen supply pipe, and a T-shaped three-way tube connected to the top of which is connected to the top of which is connected to the tracheostomy tube via an oxygen inhalation tube, and the other end of which is an outlet tube; the top of the jet-type nebulizer chamber is also provided with a drug injection port with internal threads and a sealing cap, and after the sealing cap is opened, the drug injection port is connected to a sterile water container and a normal saline container via a liquid supply pipeline, the liquid supply pipeline including a branch pipe I connected to the sterile water container, a branch pipe II connected to the normal saline container, a mixing chamber, and a mixing pipeline connecting the mixing chamber and the drug injection port, and a quick connector with external threads is provided at the lower end of the mixing pipeline to match the drug injection port.

[0006] Furthermore, the lower ends of both branch pipe I and branch pipe II are connected to the mixing chamber and fit against the inner wall of the mixing chamber, and a spiral mixing guide strip is provided on the inner wall of the mixing chamber.

[0007] Furthermore, a control switch is installed on the mixing pipeline.

[0008] Furthermore, the control switch is a roller-type flow rate regulator.

[0009] Furthermore, the sealing cap has a collar that fits onto the vertical tube of the T-shaped tube.

[0010] Furthermore, the sidewall of the jet-type atomizing chamber is provided with graduations.

[0011] Furthermore, the middle section of the air outlet pipe is a concave U-shaped pipe or a V-shaped pipe.

[0012] Furthermore, both the sterile water container and the saline container are equipped with hooks.

[0013] The beneficial effects of adopting the above technical solution are as follows: This utility model can automatically mix sterile water and physiological saline to prepare a humidifying solution during the liquid addition process, saving the work of preparing the solution; in addition, during the oxygen delivery to tracheostomy patients, the prepared humidifying solution can be continuously and slowly injected into the jet nebulizer chamber, avoiding nursing problems caused by too much or too little humidifying solution in the jet nebulizer chamber, and reducing the workload of intermittent liquid injection.

[0018] See appendix Figure 1 and 2In one specific embodiment of this utility model, the structure includes a jet-type nebulizer chamber. The bottom of the jet-type nebulizer chamber is connected to an oxygen source via an oxygen supply pipe. The top of the jet-type nebulizer chamber is connected to a T-shaped three-way connector. One end of the horizontal tube of the three-way connector is connected to a tracheostomy tube via an oxygen inhalation tube, and the other end of the horizontal tube is an outlet tube. The top of the jet-type nebulizer chamber also has a threaded injection port with a sealing cap. After the sealing cap is opened, the injection port is connected to a sterile water container and a saline container via a liquid supply line. The liquid supply line includes a branch pipe I connecting to the sterile water container, a branch pipe II connecting to the saline container, a mixing chamber, and a mixing pipe connecting the mixing chamber and the injection port. The lower end of the mixing pipe is equipped with a quick-connect fitting that matches the injection port. The quick-connect fitting has external threads. A Luer connector can also be used. Sterile water and saline solution flow from sterile water container and saline solution container respectively into the mixing chamber through branch pipe I and branch pipe II for mixing. Then, they flow into the jet nebulization chamber through the mixing pipeline, where they are impacted and atomized by the oxygen jet. After being moistened with oxygen, the oxygen is delivered to the patient through the three-way tube and oxygen inhalation tube.

[0019] The lower ends of branch pipe I and branch pipe II are both connected to the mixing chamber and adhere to the inner wall of the mixing chamber. A spiral mixing guide strip is provided on the inner wall of the mixing chamber. Sterile water and physiological saline are dripped onto the guide strip and thoroughly mixed as they spiral down along the guide strip, preventing unmixed liquid from entering the jet atomizing chamber.

[0020] A control switch is installed on the mixing pipeline. The control switch is a roller-type flow rate regulator. The supply rate of the humidifying liquid is adjusted by the control switch.

[0021] The sealing cap has a collar that fits onto the vertical section of the T-shaped tube. Even after the sealing cap is opened, it remains connected to the T-shaped tube via the collar to prevent loss.

[0022] The side wall of the jet atomizing chamber is equipped with graduations. The graduations facilitate observation of the liquid level of the humidifying liquid inside the jet atomizing chamber, allowing for timely adjustment of the flow rate via a control switch.

[0023] The middle section of the air outlet pipe is a concave U-shaped tube. The U-shaped tube can prevent the humidifying liquid or oxygen after atomization from being discharged from the air outlet pipe, thus avoiding the problem of dampness in the hospital bed.

[0024] Both the sterile water container and the saline container are equipped with hooks. The hooks facilitate hanging the sterile water container and the saline container at a high position.

[0025] The above description is only presented as a feasible technical solution of this utility model and is not intended as a single limitation on the technical solution itself.
