Description

Technical Field

[0001] The utility model relates to the technical field of laryngoscope catheters, in particular to a laryngoscope catheter with a tracheal balloon rapid inflation function. Background Art

[0002] The laryngoscope catheter is a thin and long instrument, usually made of flexible materials, used to examine and treat the throat. By inserting the laryngoscope catheter into the patient's mouth, the doctor can clearly observe the condition of the larynx, including the vocal cords, throat and other parts. During use, the laryngoscope catheter is inserted into the patient's airway, and then the guide wire is pulled out and the sheet is torn open, so that the air stored in the balloon enters the balloon, and the tracheal balloon is quickly inflated, thereby reducing the operation steps and time, which helps to quickly establish an airway channel in an emergency.

[0003] When the airbag of the existing laryngoscope catheter is stored, the air stored in the airbag is easily squeezed by elastic force and leaks slowly because the airbag is soft. At the same time, it is difficult for the stored air to be stably squeezed into the balloon to prop up the balloon, thereby reducing the fixing effect of the laryngoscope catheter.

[0004] Therefore, a laryngoscope catheter with a tracheal balloon rapid inflation function is proposed to solve the above problems. Utility Model Content

[0005] The purpose of the utility model is to provide a laryngoscope catheter with a tracheal balloon rapid inflation function in order to solve the above problems, thereby improving the problem of poor fixation effect of the laryngoscope catheter.

[0006] The utility model achieves the above-mentioned purpose through the following technical solutions: a laryngoscope catheter with a function of rapid inflation of a tracheal balloon, comprising: a laryngoscope catheter, the surface of which is fixedly connected with a balloon, the inner wall of which is connected with a delivery tube, the other end of which penetrates and extends out of the inner wall of the laryngoscope catheter; an inflation mechanism, which is used to deliver gas to the inside of the balloon and is arranged at one end of the delivery tube; wherein the inflation mechanism comprises a cylinder connected to one end of the delivery tube, the inner wall of which is slidably connected with a piston, the surface of which is embedded with a first one-way valve, and the surface of which is provided with an inflation assembly. The cylinder and the piston are used to deliver gas to the balloon, so that the balloon can be fully and quickly propped up, thereby ensuring the fixing effect of the laryngoscope catheter, and the first one-way valve is used to enable the gas in the cylinder to flow into the balloon through the delivery tube, thereby preventing the gas in the balloon from flowing into the cylinder through the delivery tube.

[0007] Preferably, the inflation assembly includes an air inlet pipe fixedly connected to one end of the inner wall of the cylinder, and a second one-way valve is embedded and installed on the surface of the air inlet pipe. The air inlet pipe is used to allow air to enter the cylinder, ensuring that the balloon has enough gas to be propped up, and the second one-way valve is used to allow air to flow into the cylinder through the air inlet pipe, preventing the gas in the cylinder from being discharged through the air inlet pipe.

[0008] Preferably, a connecting tube is provided on the surface of the barrel, and the surface of the connecting tube is threadedly connected to the inner wall of the delivery tube. The connecting tube is used to realize the disassembly and assembly of the barrel and the delivery tube, avoiding the barrel and the laryngoscope catheter being thrown away together after the disposable laryngoscope catheter is used, thereby ensuring that the barrel can be reused.

[0009] Preferably, one end of the connecting pipe and the delivery pipe are both fixedly connected with a sealing ring, so as to ensure the tightness of the cylinder body and the delivery pipe after being connected.

[0010] Preferably, the upper end of the surface of the delivery tube is fixedly connected with an air outlet pipe, and the inner wall of the air outlet pipe is clamped with a sealing plug. The air outlet pipe is used to discharge the gas in the balloon, and the fixation of the laryngoscope catheter in the human body is simple.

[0011] Preferably, an elastic block is fixedly connected to the surface of the sealing plug, and one side of the elastic block is fixedly connected to the surface of the air outlet pipe. The elastic block is used to restrict the sealing plug and prevent the sealing plug from being lost.

[0012] Preferably, the inner wall of the connecting tube is rollingly connected with a ball, and the surface of the ball is rollingly connected to the surface of the cylinder. The ball ensures that the cylinder will not rotate when the connecting tube rotates, ensuring the convenience of disassembly and assembly of the cylinder and the delivery pipe.

[0013] The beneficial effects of the utility model are:

[0014] 1. The cylinder and the piston are used to deliver gas to the balloon, ensuring that the balloon can be fully and quickly propped up, thereby ensuring the fixing effect of the laryngoscope catheter. The first one-way valve is used to enable the gas in the cylinder to flow into the balloon through the delivery tube, preventing the gas in the balloon from flowing into the cylinder through the delivery tube. The air inlet pipe is used to enable air to enter the cylinder, ensuring that the balloon has enough gas to prop up. The second one-way valve is used to enable air to flow into the cylinder through the air inlet pipe, preventing the gas in the cylinder from being discharged through the air inlet pipe.

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] When implementing: Figure 1-4 As shown, a laryngoscope catheter with a tracheal balloon rapid inflation function comprises: a laryngoscope catheter 1, a balloon 2 is fixedly connected to the surface of the laryngoscope catheter 1, the inner wall of the balloon 2 is connected to a delivery tube 3, and the other end of the delivery tube 3 penetrates and extends out of the inner wall of the laryngoscope catheter 1; an inflation mechanism 4, which is used to transport gas to the inside of the balloon 2 and is arranged at one end of the delivery tube 3; wherein the inflation mechanism 4 comprises a cylinder 41 connected to one end of the delivery tube 3, a piston 42 is slidably connected to the inner wall of the cylinder 41, a first one-way valve 43 is embedded and installed on the surface of the cylinder 41, an inflation component 44 is arranged on the surface of the cylinder 41, and the inflation component 44 comprises an air inlet pipe 441 fixedly connected to one end of the inner wall of the cylinder 41, and a second one-way valve 442 is embedded and installed on the surface of the air inlet pipe 441.

[0024] It should be noted that the laryngoscope catheter 1, balloon 2, first one-way valve 43, second one-way valve 442, etc. in the above description are all relatively mature devices in the existing technology, and the specific models can be selected according to actual needs.

[0025] When it is necessary to examine and treat the patient's throat, the laryngoscope catheter 1 is inserted into the corresponding position in the patient's mouth, pushing the piston 42 to move back and forth in the cylinder 41. During the reciprocating movement of the piston 42, air enters the cylinder 41 through the air inlet pipe 441, and the gas in the cylinder 41 is pushed into the balloon 2 through the tube 3. The gas in the balloon 2 is quickly sufficient and propped up, so that the laryngoscope catheter 1 is fixed in the human trachea. At this time, the laryngoscope catheter 1 begins to examine or treat the patient's throat.

[0026] like Figure 3 As shown, a connecting tube 443 is provided on the surface of the cylinder 41, and the surface of the connecting tube 443 is threadedly connected to the inner wall of the delivery pipe 3. A sealing ring 444 is fixedly connected to one end of the connecting tube 443 and the delivery pipe 3. A ball 448 is rollingly connected to the inner wall of the connecting tube 443, and the surface of the ball 448 is rollingly connected to the surface of the cylinder 41.

[0027] When the cylinder 41 needs to be connected to the pipe 3, the connecting pipe 443 is aligned and abutted against the pipe 3 and the connecting pipe 443 is rotated to make the cylinder 41 and the pipe 3 threadedly connected, so that the two sealing rings 444 abut against each other, thereby making the cylinder 41 and the pipe 3 tightly connected.

[0028] When the laryngoscope catheter 1 needs to be thrown into a medical waste bin, the connecting tube 443 is rotated to separate the connecting tube 443 from the delivery tube 3, so that the barrel 41 is separated from the delivery tube 3, and the laryngoscope catheter 1 can be thrown into the medical waste bin.

[0029] like Figure 4 As shown, the upper end of the surface of the delivery pipe 3 is fixedly connected to an air outlet pipe 445, the inner wall of the air outlet pipe 445 is clamped with a sealing plug 446, the surface of the sealing plug 446 is fixedly connected to an elastic block 447, and one side of the elastic block 447 is fixedly connected to the surface of the air outlet pipe 445.

[0030] When it is necessary to remove the laryngoscope catheter 1 in the patient's throat, pull the sealing plug 446 to open the air outlet pipe 445. At this time, the gas in the balloon 2 is discharged through the tube 3 and the air outlet pipe 445, releasing the fixation of the laryngoscope catheter 1 in the patient's throat, and pull the laryngoscope catheter 1 away from the patient's mouth.

[0031] When the utility model is in use, the laryngoscope catheter 1 is inserted into the corresponding position in the patient's oral cavity, pushing the piston 42 to reciprocate in the cylinder 41. During the reciprocating movement of the piston 42, air enters the cylinder 41 through the air inlet pipe 441, and the gas in the cylinder 41 is pushed into the balloon 2 through the delivery tube 3. The gas in the balloon 2 is quickly sufficient and propped up, so that the laryngoscope catheter 1 is fixed in the human trachea. At this time, the laryngoscope catheter 1 begins to examine or treat the patient's throat; the sealing plug 446 is pulled to open the air outlet pipe 445. At this time, the gas in the balloon 2 is discharged through the delivery tube 3 and the air outlet pipe 445, so that the laryngoscope catheter 1 is fixed to the patient's throat, and the laryngoscope catheter 1 is pulled to keep it away from the patient's oral cavity.

[0032] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
