Description

A type of suction tube to prevent hypoxia Technical Field

[0001] This invention relates to the field of medical device technology, and in particular to a suction catheter for preventing hypoxia. Background Technology

[0002] In clinical emergency and critical care, suctioning is a common and crucial procedure used to clear secretions from the airway and maintain airway patency, especially for patients who cannot cough up phlegm on their own. Timely suctioning can prevent lung infections and respiratory failure. However, traditional suctioning requires inserting the suction catheter into the patient's airway, which inevitably temporarily blocks or interferes with the patient's normal oxygen intake.

[0003] Currently used clinical suction catheters have a single function, only providing negative pressure suction. During suctioning, the suction catheter occupies airway space and the negative pressure removes some air from the lungs, which can easily lead to hypoxemia in patients. This is especially true when the sputum is thick and requires repeated and prolonged suctioning, putting patients at extremely high risk of hypoxia and suffocation. In addition, existing equipment often lacks a direct display and precise adjustment mechanism for suction negative pressure. Medical staff often rely on experience to operate, which can easily damage the airway mucosa due to excessive negative pressure or result in incomplete suctioning due to insufficient negative pressure. Furthermore, there is a lack of safety structures to prevent backflow of waste.

[0004] Therefore, this invention proposes an anti-hypoxia suction catheter to address the shortcomings of existing technologies. Summary of the Invention

[0005] In view of the problems in the prior art, such as the inability of ordinary suction catheter components to provide oxygen synchronously during emergency suctioning operations, which can easily lead to hypoxia and suffocation in patients, and the lack of a negative pressure visual adjustment mechanism in existing equipment, which results in low operational safety and easy damage to the airway mucosa, the present invention aims to provide a hypoxia-preventing suction catheter with an improved structure that can effectively solve the above problems.

[0006] This invention provides an anti-hypoxia suction catheter, comprising: an oxygen inhalation tube, a suction catheter assembly, a three-way tube, a fixing shell, a check valve, a valve core, a branch tube, a connecting tube, a sleeve, a pneumatic pump, and a regulating valve.

[0007] The suction tube assembly is installed inside the oxygen inhalation tube, forming a coaxial channel structure for internal suction and external oxygen supply. The right end of the oxygen inhalation tube and the right end of the suction tube assembly are connected to the three-way tube. The fixing shell is fixedly connected to the periphery of the three-way tube, and the fixing shell covers the outer surface of the three-way tube. The left end of the three-way tube is fixedly connected to the check valve, and the valve core is installed in the middle of the inner side of the check valve. A corrugated pipe is fixedly connected to the pipe connection of the three-way tube. The right end of the three-way tube is connected to the branch pipe and the connecting pipe. The air pressure pump is installed on the periphery of the end of the connecting pipe away from the three-way tube. The sleeve is fixedly connected to the left end of the air pressure pump at the connection of the connecting pipe. The regulating valve is fixedly connected to the middle of the air pressure pump, and the two ends of the regulating valve are connected between the internal pipeline of the connecting pipe and the air pressure pump.

[0008] Preferably, a switch is installed at the top of the air pump, and a control board is electrically connected to the bottom of the switch. The control board is located inside the air pump, and the air pump is started and stopped by the switch, thereby improving the convenience of operation.

[0009] Preferably, a display screen is installed on the top surface of the air pump. The display screen is electrically connected to the internal circuit of the air pump and is used to display the pressure values ​​inside the air pump and pipeline in real time, so as to facilitate monitoring by the operator.

[0010] Preferably, the right end of the air pump is fixedly connected to a connection hole, and a sealing plug is installed on the right end of the outer wall of the connection hole to seal the connection hole and prevent external impurities from entering the equipment.

[0011] Preferably, the sealing plug is inserted into the port of the connection hole, and the sealing plug and the connection hole are interference-fitted to ensure the sealing performance of the end of the air pressure pump.

[0012] Preferably, the branch pipe is connected to the side wall of the three-way pipe, and the branch pipe is used to connect to an external oxygen source so that oxygen can enter the oxygen inhalation tube through the three-way pipe.

[0013] Preferably, the fixing shell covers the periphery of the connection node between the three-way tube, the oxygen inhalation tube, and the suction tube assembly, in order to enhance the structural strength of the tube junction and prevent the connection from loosening.

[0014] Preferably, the left end of the suction tube assembly extends beyond the left end of the oxygen inhalation tube, which facilitates the suction tube assembly to penetrate deep into the patient's airway for precise suctioning, while avoiding accidental aspiration of gas from the oxygen flow path.

[0015] The present invention has the following beneficial effects: 1. The present invention solves the problems of hypoxia risk and easy backflow of suctioned material when performing suctioning on adult patients by using a coaxial structure through which the suction tube assembly is installed inside the oxygen inhalation tube and a diversion design of the three-way tube, and with the one-way control structure of the check valve. This is achieved by maintaining continuous oxygen supply while performing deep airway suctioning, effectively preventing patient suffocation, eliminating backflow of waste, and significantly improving the safety of operation.

[0016] 2. This invention solves the problem that existing suctioning equipment lacks precise negative pressure adjustment and real-time numerical monitoring functions, which can easily damage the airway mucosa due to excessive negative pressure or cause incomplete suctioning due to insufficient negative pressure by integrating an air pressure pump assembly with a regulating valve, at the end of the connecting pipe. This allows operators to intuitively monitor the values ​​on the display screen and accurately control the suction force using the regulating valve, realizing visualization and controllability of the suctioning process, effectively protecting the patient's airway mucosa and improving suctioning efficiency.

[0019] To make the objectives, technical solutions, and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Example: Referring to Figures 1 to 5, this embodiment of the invention provides a hypoxia-preventing suction catheter, which aims to solve the problems in the prior art where the oxygen supply cannot be maintained during suctioning of patients, leading to the risk of hypoxia, as well as the structural defects of lacking precise adjustment and real-time monitoring of negative pressure.

[0021] Referring to Figures 1 and 2, an anti-hypoxia suction catheter includes an oxygen tube 1 and a suction catheter assembly 2 that penetrates the interior of the oxygen tube 1. The oxygen tube 1 serves as the outer conduit for continuously delivering oxygen to the patient's airway during the procedure, while the suction catheter assembly 2 is located in the inner layer for penetrating deep into the airway to remove mucus or foreign objects. The coaxial arrangement of the two achieves the functional effect of simultaneous oxygen supply and suction without interference.

[0022] The right end of the oxygen inhalation tube 1 and the right end of the suction tube assembly 2 are connected to a three-way tube 5. A fixing shell 3 is fixedly connected to the outside of the three-way tube 5. The fixing shell 3 covers the outer surface of the three-way tube 5. The fixing shell 3 is used to increase the structural strength and connection stability of the pipe junction and prevent loosening during operation. The three-way tube 5 serves as a flow branching node between the gas and liquid circuits to enable independent operation of each pipe and ensure convenient operation.

[0023] Multiple corrugated pipes 4 are fixedly connected to the pipe connection between the three-way pipe 5 and the oxygen inhalation tube 1, and to the pipe connection between the three-way pipe 5 and the suction tube assembly 2. The corrugated pipes 4 are sealed at the port of the three-way pipe 5. The corrugated pipes 4 use their own expansion and contraction characteristics to ensure the sealing of the structural connection and prevent gas leakage. A check valve 7 is fixedly connected to the left end of the three-way pipe 5. A valve core 8 is installed in the middle of the inner side of the check valve 7. The check valve 7 and the valve core 8 are used to control the flow of fluid in one direction to prevent the suctioned gas and liquid from flowing back into the pipeline and ensure the safety of the user.

[0024] Referring to Figures 3 and 4, the right end of the three-way pipe 5 is connected to a branch pipe 6 and a connecting pipe 9. The branch pipe 6 is connected to the side wall of the three-way pipe 5 and its axial direction is set at a predetermined angle with the axial direction of the connecting pipe 9. The branch pipe 6 is used to conveniently connect to the external oxygen source operating equipment, improving the convenience of operation, so that oxygen can enter the oxygen inhalation pipe 1 through the branch pipe 6 and the three-way pipe 5. The connecting pipe 9 is used to connect to the negative pressure source during the transmission process. A pressure pump 14 is installed on the periphery of the connecting pipe 9 to facilitate the adjustment of the internal negative pressure.

[0025] A sleeve 10 is fixedly connected to the left end of the air pump 14 at the connection point with the connecting pipe 9. The sleeve 10 is tightly fitted onto the outer wall of the connecting pipe 9. The sleeve 10 is used to improve the sealing of the connection between the air pump 14 and the connecting pipe 9, and to prevent air leakage at the connection point from affecting the negative pressure effect. A connecting hole 12 is fixedly connected to the right end of the air pump 14. The connecting hole 12 communicates with the internal space of the air pump 14. A sealing plug 13 is installed on the right end of the outer wall of the connecting hole 12. The sealing plug 13 is detachably inserted into the port of the connecting hole 12 to ensure structural sealing and prevent impurities from entering.

[0026] A switch 11 for easy operation is installed at the top of the air pump 14. The switch 11 is used to control the air pump 14 to turn on and off. The bottom of the switch 11 is electrically connected to the control board 15. The control board 15 is fixedly installed in the internal cavity of the air pump 14. The control board 15 is used to process the signal from the switch 11 and control the operation of the equipment, thereby increasing the accuracy of operation.

[0027] As a preferred embodiment, in order to achieve accurate negative pressure regulation, ensure user safety and operational efficiency, please refer to Figure 5. A regulating valve 16 is fixedly connected to the middle of the air pump 14. The two ends of the regulating valve 16 are respectively connected between the connecting pipe 9 and the internal negative pressure pipeline of the air pump 14. The regulating valve 16 adjusts the suction force inside the connecting pipe 9 by changing the pipe diameter or by bypassing the flow, so that the operator can flexibly control the suction force according to the actual situation.

[0028] As another preferred embodiment, in order to facilitate real-time monitoring of the internal pressure status, a display screen 17 is installed on the top surface of the air pump 14 for easy display. The display screen 17 is electrically connected to the pressure sensor and control board 15 inside the air pump 14. The display screen 17 is used to accurately display the pressure values ​​inside the air pump 14 and the pipeline, so that medical staff can read the data intuitively.

[0029] As another preferred embodiment, in order to further ensure the safety and convenience of the suctioning operation, the length of the suction tube assembly 2 is designed to be greater than the length of the oxygen tube 1, so that the left end of the suction tube assembly 2 extends beyond the left end of the oxygen tube 1, which makes it easier for the suction tube assembly 2 to go deeper into the patient's airway for precise suctioning. At the same time, the branch tube 6 is connected to the side wall of the three-way tube 5. The branch tube 6 is used to connect to an external oxygen source, and the axial direction of the branch tube 6 is set at an acute angle to the axial direction of the connecting tube 9, which is beneficial to airflow guidance.

[0030] Working principle: This system performs airway suctioning while ensuring oxygen supply to a patient experiencing asphyxiation. Before suctioning, the operator checks the suction device's performance and the connection between the oxygen tubing 1 and the suction tubing assembly 2. The operator assists the patient to assume a supine or lateral position. An external oxygen source is connected to the branch tube 6. Oxygen flows through the branch tube 6 into the three-way valve 5 and into the oxygen tubing 1, maintaining a continuous oxygen supply. The operator inserts the suction tubing assembly 2 into the patient's airway without activating negative pressure suction. The suction tubing assembly 2 extends deep into the oxygen tubing 1 for convenient suctioning. During suctioning, the operator presses the switch 11 at the top of the air pressure pump 14. Switch 11 activates the air pressure pump 14 via the control panel 15. The air pressure pump 14 generates negative pressure within the connecting pipe 9. The operator observes the display on the top surface of the air pressure pump 14. The display screen 17 shows the values, and the appropriate suction negative pressure is set by adjusting the regulating valve 16 in the middle of the air pressure pump 14. The regulating valve 16 achieves accurate negative pressure adjustment. The operator controls the suction tube assembly 2 to rotate and lift it upward to prevent damage to the mucosa. The suctioned mucus passes through the suction tube assembly 2 and the three-way tube 5 in sequence and enters the connecting tube 9. During the fluid transmission process, the fixed shell 3 increases the stability of the connection and fixation of the three-way tube 5. The check valve 7 at the left end of the three-way tube 5, together with the valve core 8, prevents gas and liquid backflow and ensures user safety. The multiple corrugated pipes 4 at the connection of the three-way tube 5 and the sleeve 10 at the connection of the air pressure pump 14 ensure the sealing of the structural connection and prevent impurities from entering. After the operation is completed, the sealing plug 13 on the outer wall of the connection hole 12 ensures the sealing of the right end of the air pressure pump 14.
