Description

Technical Field

[0001] The present invention relates to the field of measuring the vital capacity of patients with tracheotomy cannulas, and specifically to a connecting tube for a vital capacity measuring device for tracheotomy patients. Background Art

[0002] The vital capacity measuring device measures the vital capacity of a patient by blowing air or inhaling air and observing the height of a sphere inside the machine. When inhaling and exhaling, the connecting pipeline will be adjusted to ensure that the ball floats upwards. Such measuring machines are relatively common. When a patient uses it, the trachea on the respiratory measurement is connected to the mouth, and a mask is detachably connected to the end of the trachea. The mask can be put on the mouth. However, this is not very convenient for tracheotomy patients because tracheotomy patients have a tracheotomy cannula at the back and cannot use the mask, and the intubation cannot be directly connected to the trachea of the measuring device. Therefore, how to facilitate the connection between the trachea of the vital capacity measuring device and the tracheotomy cannula is an urgent problem for those skilled in the art. Summary of the Invention

[0003] The purpose of the present invention is to provide a connecting tube for a vital capacity measuring device for tracheotomy patients to solve the problems raised in the above background art.

[0004] To achieve the above purpose, the present invention provides the following technical solution: A connecting tube for a vital capacity measuring device for tracheotomy patients includes a tube body. One end of the tube body is provided with a tubular cannula connector for connecting to the tracheotomy cannula. The cannula connector is tubular and made of rigid plastic, and can be inserted into or sleeved on the tracheotomy cannula. The other end of the tube body is provided with a tubular measuring device connector for connecting to the trachea of the vital capacity measuring device. It also includes a branch tube connected to the tube body, and the branch tube is close to the cannula connector to shorten the ventilation distance. The branch tube is connected with a plugging mechanism for closing the air inlet and outlet. The measuring device transmits gas through the trachea, and a mask is generally connected to the end of the trachea, but it can be removed. Here, the measuring device connector can be directly inserted into the trachea after the mask is removed. When normally connecting, first connect one end of the tracheotomy cannula or one end of the measuring device. Although the cannula connector and the measuring device connector on the tube body facilitate the connection and realize the measurement of the vital capacity of tracheotomy cannula patients, during the connection process, the breath will pass through the tube body to reach the trachea of the measuring device and then to the measuring device. The tube body increases the length, which is not conducive to ventilation, and is likely to cause stuffiness and affect the test results. Therefore, a branch tube is added. The branch tube is close to the tracheotomy cannula, and the patient can breathe directly. When the patient starts the test, after inhaling or exhaling, the plugging mechanism closes to realize the measurement. Here, the branch tube ensures normal smooth breathing.

[0005] Preferably, the plugging mechanism is a cap sleeved on the end of the branch tube. Before the cannula connector and the measuring device connector are not connected properly, the branch tube is ventilated. After they are connected, the cap is put on for measurement.

[0006] Preferably, the plugging mechanism includes a rigid catheter connected to the end of the branch pipe. The distal end of the catheter is closed, and a plurality of air exchange ports are provided in the circumferential direction of the catheter. There is a closed distance between the air exchange ports and the distal end of the catheter to ensure that when the sleeve returns, the air exchange ports can be completely blocked to ensure sealing. It also includes a sleeve sleeved on the catheter. When the sleeve slides outwards, it can block the air exchange ports. The sleeve is connected to the inner wall of the distal end of the catheter through an elastic member, and the sleeve is connected with a pulling mechanism. After the measuring device connector is inserted into the trachea, under the action of the elastic member, the sleeve is pulled back to block the air exchange ports. The air exchange ports are strip-shaped along the catheter, and four are symmetrically arranged. Here, the tracheotomy cannula is first connected, and the pulling mechanism pulls the sleeve, and the air exchange ports are exposed for normal breathing and ventilation. When the measuring device connector is connected, under the action of the elastic member, the pulling mechanism returns to its original position, and the sleeve automatically blocks the air exchange ports, thus facilitating the start of the test. In this way, there is no need for manual closing, and it automatically closes when the measuring device connector is connected, which is simple and convenient.

[0007] Preferably, the elastic member is a rubber strip, which is simple and convenient, and can also be a spring.

[0008] Preferably, the pulling mechanism includes a "cross"-shaped bracket fixed in the middle of the inner wall of the sleeve. The inner end of the rubber strip is fixed on the bracket, and a guiding groove corresponding to the bracket is provided on the catheter. The guiding groove is located between the air exchange ports. The reason why the bracket is in the middle of the sleeve is mainly that when the sleeve returns to its original position, it can completely block the air exchange ports. The bracket is connected with a pull rope. It also includes an elastic tilting mechanism arranged on the measuring device connector. The pull rope passes through the catheter and the tube body from the inside in sequence and is connected with the tilting mechanism. After the measuring device connector is inserted into the trachea, the tilting mechanism is squeezed and received to make the pull rope retract towards the catheter. The tilting mechanism tightens the pull rope, stretches the rubber strip, and the sleeve moves away to expose the air exchange ports.

[0009] Preferably, the tilting mechanism includes an arc-shaped elastic piece, and one end of the elastic piece close to the tube body tilts to generate elastic tension. A receiving groove for receiving the elastic piece is provided on the measuring device connector. The elastic piece is arc-shaped and has elasticity to pull the sleeve and expose the air exchange ports. After the trachea is sleeved, the elastic piece is received into the receiving groove. Here, the elasticity of the elastic piece is not only used to pull the pull rope initially, but also can press against the inner wall of the trachea after being received to increase the friction force and achieve fixation.

[0010] Preferably, two elastic pieces are symmetrically arranged, and the end of the pull rope bifurcates into a "Y" shape and is respectively connected to the ends of the two elastic pieces, so the pulling effect is good.

[0011] Preferably, the receiving groove is dug from the measuring device connector by the elastic piece, which is easy to process.

[0012] Preferably, the elastic piece is made of plastic material and has good elasticity.

[0013] Preferably, the tube body and the branch pipe are made of the same material as the infusion set, taking into account both hardness and softness. The wall thickness can be 1 mm, which can be bent without wrinkling.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0015] 1. First, connect the sleeve joint to the tracheotomy cannula. Although the length of the tube body is increased, the branch pipe is close to the tracheotomy cannula, so normal ventilation and breathing are ensured. Then, connect the measuring device joint to the trachea of the vital capacity measuring device. After preparing for breathing, cover the cap and perform the vital capacity measurement. Here, the branch pipe ensures normal breathing before measurement, which is safer and more reliable.

[0016] 2. The second method is more convenient. When connecting the measuring device joint, the elastic piece is squeezed and retracted into the receiving groove. The pull rope is pulled back under the traction of the rubber strip. At the same time, the sleeve blocks the air exchange port and performs the vital capacity measurement. Here, there is no need to manually close the air exchange port, which is more labor-saving and convenient. At the same time, the elastic piece is located in the trachea and presses against the inner wall of the trachea, increasing the friction force and improving the fixing effect to avoid loosening.

[0024] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0025] Embodiment 1

[0026] Please refer to Figures 1 to 2 , the present invention provides a technical solution for a connecting tube of a vital capacity measuring device for tracheostomy patients: a connecting tube of a vital capacity measuring device for tracheostomy patients, including a tube body 1. One end of the tube body 1 is provided with a tubular sleeve joint 2 for connecting a tracheostomy cannula. The sleeve joint 2 is tubular and made of rigid plastic, which can be inserted into or sleeved on the tracheostomy cannula. The other end of the tube body 1 is provided with a tubular measuring device joint 3 for connecting the trachea of the vital capacity measuring device. It also includes a branch tube 4 connected to the tube body 1, and the branch tube 4 is close to the sleeve joint 2 to shorten the ventilation distance. The branch tube 4 is connected with a plugging mechanism for closing the air inlet and outlet. The measuring device transmits gas through the trachea. Generally, a face mask is connected to the end of the trachea, but it can be removed. Here, the measuring device joint 3 can be directly inserted into the trachea after the face mask is removed. During normal connection, first connect one end of the tracheostomy cannula or one end of the measuring device. Although the sleeve joint 2 and the measuring device joint 3 on the tube body 1 facilitate the connection and realize the measurement of the vital capacity of tracheostomy cannula patients, during the connection process, the breath will pass through the tube body 1 to the trachea of the measuring device and then to the measuring device. The increase in the length of the tube body 1 is not conducive to ventilation, and it is easy to cause stuffy feelings and possible impacts on the test results. Therefore, the branch tube 4 is added. The branch tube 4 is close to the tracheostomy cannula, and the patient can breathe directly. When the patient starts the test, after inhaling or exhaling, the plugging mechanism closes to realize the measurement. Here, the branch tube 4 ensures normal smooth breathing. Both the tube body 1 and the branch tube 4 are made of the same material as the infusion set, taking into account both hardness and softness. The wall thickness can be 1 mm, which can be bent without wrinkling.

[0027] The plugging mechanism is a cap 5 sleeved on the end of the branch tube 4. Before the sleeve joint 2 and the measuring device joint 3 are not connected properly, the branch tube 4 is ventilated. After connection, the cap 5 is covered for measurement.

[0028] Embodiment 2

[0029] Please refer to Figures 3 to 6, compared with Embodiment 1, the difference here lies in the plugging mechanism. The plugging mechanism includes a rigid catheter 6 connected to the end of the branch pipe 4. The distal end of the catheter 6 is closed, and a plurality of ventilation openings 7 are provided in the circumferential direction of the catheter 6. There is a closed distance between the ventilation openings 7 and the distal end of the catheter 6 to ensure that when the sleeve 8 returns, it can completely block the ventilation openings 7 to ensure sealing. It also includes a sleeve 8 sleeved on the catheter 6. When the sleeve 8 slides outwards, it can block the ventilation openings 7. The sleeve 8 is connected to the inner wall of the distal end of the catheter 6 through an elastic member, and the sleeve 8 is connected with a pulling mechanism. After the measuring device connector 3 is inserted into the trachea, under the action of the elastic member, the sleeve 8 is pulled back to block the ventilation openings 7. The ventilation openings 7 are strip-shaped along the catheter 6, and four are symmetrically arranged. Here, the tracheotomy cannula is first connected, the pulling mechanism pulls the sleeve 8, and the ventilation openings 7 are exposed for normal breathing and ventilation. When the measuring device connector 3 is connected, under the action of the elastic member, the pulling mechanism returns to its original position, and the sleeve 8 automatically blocks the ventilation openings 7, thus facilitating the start of the test. In this way, there is no need for manual closing, and it automatically closes when the measuring device connector 3 is connected, which is simple and convenient. The elastic member is a rubber strip 9, which is simple and convenient, and can also be a spring.

[0030] The pulling mechanism includes a "cross"-shaped bracket 10 fixed to the middle part of the inner wall of the sleeve 8. The inner end of the rubber strip 9 is fixed to the bracket 10, and a guiding groove 11 corresponding to the bracket 10 is provided on the catheter 6. The guiding groove 11 is located between the ventilation openings 7. The reason why the bracket 10 is in the middle of the sleeve 8 is mainly that when the sleeve 8 returns to its original position, it can completely block the ventilation openings 7. The bracket 10 is connected with a pull rope 12. It also includes an elastic tilting mechanism provided on the measuring device connector 3. The pull rope 12 sequentially passes through the catheter 6 and the tube body 1 from the inside and is connected to the tilting mechanism. After the measuring device connector 3 is inserted into the trachea, the tilting mechanism is squeezed and received so that the pull rope 12 retracts towards the catheter 6. The tilting mechanism tightens the pull rope 12, the rubber strip 9 is stretched, and the sleeve 8 moves away to expose the ventilation openings 7.

[0031] The tilting mechanism includes an arc-shaped elastic piece 13, and one end of the elastic piece 13 close to the tube body 1 tilts to generate elastic tension. A receiving groove 14 for receiving the elastic piece 13 is provided on the measuring device connector 3. The elastic piece 13 is arc-shaped and has elasticity. The sleeve 8 is pulled to expose the ventilation openings 7. After the trachea is sheathed, the elastic piece 13 is received into the receiving groove 14. Here, the elasticity of the elastic piece 13 is not only used to initially pull the pull rope 12, but also can press against the inner wall of the trachea after being received to increase the friction force and achieve fixation.

[0032] Two elastic pieces 13 are symmetrically arranged, and the end of the pull rope 12 branches into a "Y" shape and is respectively connected to the ends of the two elastic pieces 13, so the pulling effect is good. The accommodation groove 14 is dug from the measuring device connector 3 by the elastic piece 13, which is easy to process. The elastic piece 13 is made of plastic and has good elasticity. The pipe body 1 can be made of the same material as an infusion set, which takes into account both softness and hardness, can be bent without wrinkling. In this way, when the pull rope 12 is pulled, the length is ensured to be unchanged and the fluidity is ensured. Here, the softness and hardness are adjusted by changing the wall thickness.

[0033] Working principle: First, connect the sleeve connector 2 to the tracheotomy cannula. Although the length of the pipe body 1 is increased, the branch pipe 4 is close to the tracheotomy cannula. Therefore, normal ventilation and breathing are ensured. Then, connect the measuring device connector 3 to the trachea of the vital capacity measuring device. After getting ready to breathe, cover the cap 5 and measure the vital capacity. Here, the branch pipe 4 ensures normal breathing before measurement, which is safer and more reliable.

[0034] The second method is more convenient. When connecting the measuring device connector 3, the elastic piece 13 is squeezed and retracted into the accommodation groove 14. The pull rope 12 is pulled back under the traction of the rubber strip 9. At the same time, the sleeve 8 blocks the ventilation port 7 to measure the vital capacity. Here, there is no need to manually close the ventilation port 7, which is more convenient. At the same time, the elastic piece 13 is located in the trachea and presses against the inner wall of the trachea, increasing the friction force and improving the fixing effect to avoid loosening.

[0035] Of course, it can also be used for the tracheal connection of a vital capacity exerciser.

[0036] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
