Description

Technical Field

[0001] The invention belongs to the technical field of medical devices, and in particular relates to a microparticle humidification oxygen supply tube cutting tube with a pressure membrane. Background Art

[0002] Tracheotomy is an important means of rescuing critically ill patients. Patients who undergo tracheotomy and indwelling catheters are often seriously ill and in a critical stage. Such patients need oxygen inhalation and airway humidification care at the same time. However, the tracheotomy catheters used clinically have the following disadvantages: first, there is a lack of a dedicated humidifier. When performing airway humidification, the nurse can only place the humidification tube at the entrance of the tracheal tube and fix it with tape; second, there is a lack of a dedicated oxygen supply device. When the nurse inhales oxygen for the patient, the oxygen inhalation tube can only be inserted into the entrance of the tracheal tube and fixed with tape. In the above two situations, there have been cases in clinical practice where the nurses sealed the outlet of the tracheal tube due to mental paralysis or lack of experience when fixing it with tape, or directly placed nasal congestion at the outlet of the tracheal tube, blocking the outlet, causing the patient to have pneumothorax and carbon dioxide exhalation disorder. The former forms tension pneumothorax and causes the patient to die quickly, and the latter causes the patient to retain carbon dioxide and cause respiratory acidosis, threatening the patient's life. Summary of the invention

[0003] In view of the above problems existing in the prior art, the present invention provides a microparticle humidification oxygen supply tube cut-off tube with a pressure membrane. The humidification liquid and oxygen provided by the device enter the tracheal tube through micropores to form microparticles, which cooperate with the patient's breathing to achieve the effects of airway humidification and oxygen supply. The device is not easy to fall off during use and is simple and convenient to operate.

[0004] In order to achieve the above-mentioned purpose, the present invention provides a microparticle humidification oxygen supply tracheotomy tube with a pressure membrane, comprising an endotracheal tube 1, an inflation tube 2 and a humidification oxygen supply tube 3, the inner side wall of the endotracheal tube 1 is provided with a pressure membrane 5, a plurality of micropores 6 are distributed on the pressure membrane 5, the front section of the humidification oxygen supply tube 3 is embedded between the inner side wall of the endotracheal tube 1 and the pressure membrane 5, a plurality of micropores 6 are distributed on the front section of the humidification oxygen supply tube 3 embedded between the pressure membrane 5 and the inner side wall of the endotracheal tube 1, and the end of the front section of the humidification oxygen supply tube 3 is closed; the humidification oxygen supply tube 3 is used to provide humidification liquid and oxygen to the endotracheal tube 1.

[0005] Preferably, the length of the front section of the humidified oxygen supply tube 3 embedded between the inner wall of the endotracheal tube 1 and the pressure membrane 5 is equal to the length of the pressure membrane 5 .

[0006] Preferably, a plurality of micropores 6 are evenly distributed on the pressure membrane 5 , the pore diameter of the micropores 6 is 0.3-0.6 mm, and the arrangement interval of the micropores is 5-20 mm.

[0007] Preferably, a plurality of micropores 6 are evenly distributed on the front section of the humidified oxygen supply tube 3 , the diameter of the micropores 6 is 0.3-0.6 mm, and the arrangement spacing of the micropores is 5-20 mm.

[0008] Preferably, there is a distance between the pressure membrane 5 and the inner wall of the endotracheal tube 1 , and the distance is larger than the diameter of the humidification oxygen supply tube 3 , and the distance is 5-10 mm.

[0009] Preferably, the humidification oxygen supply tube 3 includes a humidification tube 31 and an oxygen supply tube 32 , and the humidification liquid and oxygen are supplied through the humidification tube 31 and the oxygen supply tube 32 respectively, and then mixed and enter the humidification oxygen supply tube 3 section in the tracheal tube 1 .

[0012] Through the above technical solution, the present invention has the following beneficial effects:

[0013] The present invention firstly provides a dedicated airway humidification and oxygen supply channel and interface, thereby preventing the nurse from sealing the outlet of the tracheotomy tube due to the fixing of the humidification tube and the oxygen supply tube, or causing the humidification tube and the oxygen supply tube to fall off due to loose fixing when humidifying and supplying oxygen to the patient, thereby causing serious medical accidents such as tension pneumothorax or carbon dioxide retention, or interrupting humidification and oxygen supply, thereby affecting the treatment effect of the patient; secondly, the humidification and oxygen supply tube can be embedded in the side wall of the tracheal tube for continuous humidification and oxygen supply, and then the humidification liquid and oxygen are transported into the tracheal tube through the micropores at the front end to form particles, which enter the respiratory tract and lungs through the patient's breathing, thereby playing the role of airway humidification and oxygen supply. The humidification and oxygen supply mode is close to human physiology, thereby avoiding a series of adverse reactions such as choking, breath holding, and decreased oxygen saturation caused by strong stimulation when injecting the humidification liquid.

[0018] The specific implementation of the present invention is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the present invention, and is not used to limit the present invention.

[0019] In the present invention, unless otherwise specified, directional words such as "up, down, left, right" generally refer to up, down, left, right as shown in the reference drawings; "inside and outside" refer to inside and outside relative to the outline of each component itself.

[0020] Reference Figure 1 and Figure 2 As shown, a humidification oxygen supply tube 3 is embedded in the right side wall of the tracheotomy tube currently used clinically, the front end of the humidification oxygen supply tube 3 is closed, and micropores 6 with a diameter of 0.3-0.6 mm are arranged on the inner wall of the humidification oxygen supply tube 3 at intervals of 5-20 mm. Humidification liquid and oxygen are injected through the humidification oxygen supply tube 3. After entering the humidification oxygen supply tube 3, the humidification liquid and oxygen enter the tracheal tube 1 through the humidification micropores 6, and enter the respiratory tract and lungs along with the patient's breathing and / or mechanical ventilation.

[0021] After tracheotomy, a suitable type of humidified oxygen supply tracheotomy catheter is selected according to age, gender and height, and the tracheal tube is inserted into the trachea from the incision, and then the tracheal tube plug 7 is pulled out. The patient can breathe through the tracheal tube 1 or connect to a ventilator for mechanical ventilation, and whether inflation is needed depends on the condition.

[0022] Prepare humidifying liquid and adjust oxygen flow rate according to doctor's orders, draw humidifying liquid with a syringe, load into micro-push pump, connect extension tube, open the cover on humidifying tube, connect extension tube with humidifying tube 31, connect oxygen delivery tube with oxygen supply tube 32. Adjust oxygen flow rate according to patient's hypoxia degree; adjust input speed of humidifying liquid according to doctor's orders or the properties and amount of patient's sputum, press start button of micro-push pump, and start humidification in airway.

[0023] The embodiment of the present invention provides a microparticle humidification oxygen supply tracheotomy tube with a pressure membrane, comprising a tracheal tube 1, an inflation tube 2 and a humidification oxygen supply tube 3. The tracheal tube 1 is a hollow tube with two ends connected, and a pressure membrane 5 is provided on the inner side of the tube wall. There is a certain distance between the pressure membrane 5 and the inner wall of the tracheal tube 1.

[0024] The front section of the humidified oxygen supply tube 3 is embedded in the inner wall of the tracheal tube 1. The inner wall of the tracheal tube 1 is provided with a pressure membrane 5. The pressure membrane 5 and the humidified oxygen supply tube 3 in the tracheal tube 1 are evenly provided with a plurality of micropores 6. The front end of the humidified oxygen supply tube 3 is closed.

[0025] The humidification oxygen supply tube 3 is a "Y"-shaped tube composed of a humidification tube 31 and an oxygen supply tube 32. The humidification liquid and oxygen can be mixed through the humidification tube 31 and the oxygen supply tube 32 and enter the humidification oxygen supply tube 3 section in the tracheal tube 1.

[0026] Micropores 6 are provided on the front end of the humidified oxygen supply tube 3 and the pressure membrane 5. The pore size of the micropores 6 is 0.3-0.6 mm and the arrangement interval is 5-20 mm. After the oxygen carrying the humidification liquid enters the front section of the humidified oxygen supply tube 3, it reaches the tracheal tube 1 and the pressure membrane 5. The pressure at the pressure membrane 5 increases, and the mixture of oxygen and the humidification liquid passes through the micropores 6 to form particles with very small diameters. The purpose of airway humidification is achieved as the patient breathes.

[0027] In particular, an airbag 4 is provided on the front end outer surface of the tracheal tube 1, and the airbag 4 is sealed and sleeved with the inflation tube 2. A catheter inner plug 7 is provided on the rear end outer surface of the tracheal tube 1. After the tracheal tube 1 is inserted into the patient's respiratory tract, the airbag 4 is inflated through the inflation tube 2 to become larger, and the inflation amount is adjustable; the catheter inner plug 7 is convenient for cleaning sputum produced by the patient during use, and the inflation tube 2 is an adjustable inflation pressure tube valve.

[0028] The pressure membrane 5 and the inner wall of the tracheal tube 1 form a cavity which is sealed at both ends and hollow and has micropores 6 in the middle. Oxygen and humidification liquid are mixed and enter the humidification oxygen supply tube 3 section of the inner wall of the tracheal tube 1. Since the aperture of the micropores 6 is extremely small, the local pressure at the humidification oxygen supply tube 3 section of the tracheal tube 1 is increased due to the filling of humidification liquid and oxygen. The humidification liquid and oxygen pass through the micropores 6 on the humidification oxygen supply tube 3 in the form of particles and fill the cavity formed by the pressure membrane 5 and the tracheal tube 1. As oxygen continues to enter, the pressure in the cavity at the pressure membrane 5 continues to increase, and the oxygen and humidification liquid are further mixed here. Finally, the micropores 6 on the pressure membrane 5 are passed through the front port of the tracheal tube 1 as extremely small particles carrying oxygen and humidification liquid and enter the respiratory tract.

[0029] The tracheal tube 1 is made of common medical hard plastic in the prior art, and the head of the tracheal tube 1 is a smooth cone, which facilitates the tracheal tube 1 to be inserted into the trachea during use.

[0030] The microparticle humidification oxygen supply pipe cut-out pipe with pressure membrane is connected to the humidification liquid and the oxygen supply device through the humidification pipe 31 and the oxygen supply pipe 32, and the mixing ratio of humidification and oxygen supply is adjusted according to needs.

[0031] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the present invention, which should be included in the scope of the claims of the present invention.
