[0001] The utility model relates to the technical field of ventilator connecting tubes, in particular to a connecting tube used for a facial ventilator. Background Art

[0002] Ventilators are vital for patients who cannot breathe independently. They can help patients breathe by delivering oxygen to their lungs and maintain normal levels of oxygen and carbon dioxide in the blood. They are usually used in intensive care units, operating rooms, and emergency situations. The ventilator connecting tube is an important part of the ventilator system. It is used to connect the ventilator to the patient's breathing mask to achieve oxygen delivery and exchange. However, the existing ventilator connecting tubes have problems such as unstable connection, poor sealing, and easy accumulation of fluid, which can easily lead to poor ventilator effect. Therefore, in order to improve the use effect of the ventilator, it is necessary to enhance the connection stability and sealing of the ventilator connecting tube, as well as solve the problem of fluid accumulation in the connecting tube.

[0003] One of the shortcomings of the related art is that the existing ventilator connecting tube has problems such as unstable connection, poor sealing and easy accumulation of fluid.

[0004] It can be seen that it is very necessary to provide a connecting tube for a facial ventilator that has a stable connection, strong sealing, and can discharge accumulated fluid. Utility Model Content

[0005] The utility model solves the technical problems of unstable connection, poor sealing and easy accumulation of liquid in the connecting pipe of the ventilator.

[0006] To solve the above problems, the utility model provides a connecting tube for a facial respirator, comprising: a connecting tube body, the connecting tube body is hollow inside and has a corner, the connecting tube body comprises a mask end and a respirator end; a liquid accumulation component, the liquid accumulation component is arranged at the corner of the connecting tube body, the liquid accumulation component comprises a liquid accumulation bin and a drainer; wherein the liquid accumulation bin is connected to the drainer, and the drainer can be adjusted to discharge the accumulated liquid in the liquid accumulation bin; an embedded component, the embedded component is arranged at the mask end, the embedded component comprises a threaded tube and a first inner tube, and the first inner tube is placed inside the threaded tube; a cap component, the cap component comprises a threaded cap and a second inner tube, and the second inner tube is placed inside the threaded cap, and the cap component is arranged on the breathing mask; wherein, when the connecting tube is connected to the breathing mask, the first inner tube is inserted into the second inner tube, and the connection tightness between the first inner tube and the second inner tube can be adjusted by adjusting the rotation of the threaded cap on the threaded tube.

[0007] Compared with the prior art, the technical effect achieved after adopting this technical solution is as follows: the liquid accumulation component is arranged at the corner of the connecting pipe body, and the liquid generated in the connecting pipe can be effectively collected in the liquid accumulation bin, and the liquid accumulation bin is connected with the drainer, and the drainer can be controlled to discharge the liquid collected in the liquid accumulation bin according to the actual liquid accumulation situation. The embedded component is arranged on the connecting pipe body, and the cap component is arranged on the breathing mask. The connecting pipe and the breathing mask can be firmly connected together through the rotating structure between the threaded tube and the threaded cap. The oxygen is transferred between the connecting pipe and the breathing mask through the first inner tube and the second inner tube. When the connecting pipe and the breathing mask are connected, the first inner tube is inserted into the second inner tube. By adjusting the rotation of the threaded cap on the threaded tube, the connection tightness between the first inner tube and the second inner tube can be adjusted, so that the sealing between the connecting pipe and the breathing mask can be adjusted according to the actual situation.

[0008] In an example of the present invention, the aperture of the first inner tube gradually decreases in a direction away from the connecting tube body.

[0009] Compared with the prior art, the technical effect achieved after adopting this technical solution is as follows: oxygen transmission is completed between the connecting tube and the breathing mask by inserting the first inner tube into the second inner tube. In this example, the aperture of the first inner tube gradually decreases in the direction away from the connecting tube body, so that when the first inner tube is inserted into the second inner tube, the second inner tube can definitely find a point with the same size as its own aperture. Then, by fixing the threaded tube and the threaded cap, the sealing between the connecting tube and the breathing mask can be effectively guaranteed, thereby increasing the oxygen supply effect of the facial ventilator.

[0010] In an example of the utility model, a first limit block and a second limit block are further installed on the second inner tube; wherein the threaded cap is placed between the first limit block and the second limit block, and the threaded cap can move relative to the second inner tube.

[0011] Compared with the prior art, the technical effect achieved by adopting this technical solution is that the first limit block and the second limit block are both installed on the second inner tube, and they can effectively limit the movement of the threaded cap. Among them, the second limit block is arranged near the inner thread of the threaded cap, because the threaded cap and the second inner tube are separated, the arrangement of the second limit block can effectively prevent the threaded cap from being separated from the second inner tube, and when the threaded cap and the threaded tube are connected, the threaded cap can drive the second inner tube to move toward the first inner tube, so that the first inner tube and the second inner tube can be tightly connected, and the sealing performance is enhanced.

[0012] In one example of the utility model, the drainer includes: a shell, an installation space is provided inside the shell, and a water inlet and a water outlet are provided on the shell; a rubber block, the rubber block is placed in the installation space, and a through hole is provided inside the rubber block; a first elastic component, the first elastic component is placed in the installation space and connects the shell and the rubber block; a driving component, the driving component is connected to the rubber block and is partially placed outside the shell; wherein, when the driving component drives the rubber block until the through hole is aligned with the water inlet and the water outlet, the accumulated liquid in the liquid storage tank can be discharged through the drainer.

[0013] Compared with the prior art, the technical effect achieved by adopting this technical solution is as follows: by arranging a water inlet and a water outlet on the shell, the accumulated liquid in the liquid storage bin can enter the drainer through the water inlet and then be discharged from the drainer through the water outlet. Also, by arranging a rubber block with through holes in the installation space, when the through holes on the rubber block and the water inlet and water outlet on the shell are aligned, the drainer can discharge the liquid; when the through holes on the rubber block and the water outlet and water outlet on the shell are completely misaligned, the drainer stops working. By respectively installing the first elastic component and the driving component at both ends of the rubber block, the accumulated liquid in the liquid storage bin can be selectively discharged according to actual conditions, thereby increasing the practicality and operability of the connecting pipe.

[0014] In one example of the utility model, a first blocking block and a second blocking block are also installed in the shell; when the rubber block moves to contact the first blocking block, the through hole is aligned with the water inlet and the water outlet; when the rubber block moves to contact the second blocking block, the through hole is completely staggered with the water inlet and the water outlet.

[0015] Compared with the prior art, the technical effect achieved by adopting this technical solution is as follows: by setting the first blocking block and the second blocking block in the installation space, the effect of limiting the precise movement of the rubber block can be effectively achieved. Among them, the first blocking block is arranged in the installation space, close to the side of the first elastic component. When the rubber block moves to contact with the first blocking block, the through hole is aligned with the water inlet and the water outlet, and the drainer will start to drain; when the rubber block moves to contact with the second blocking block, the through hole is completely staggered with the water inlet and the water outlet. Therefore, by simply setting the first blocking block and the second blocking block, the technical effect of accurately limiting the discharge of the drainer is achieved.

[0016] In one example of the utility model, the driving component includes a driving shaft, a second elastic component and a driving head; wherein the driving shaft connects the rubber block and the driving head, and the second elastic component is disposed on the driving shaft and between the driving head and the housing.

[0017] Compared with the prior art, the technical effect achieved by adopting this technical solution is that by installing a second elastic component between the drive head and the housing, the drive component can automatically rebound after driving the rubber block to a specified position.

[0018] In one embodiment of the utility model, a baffle is also installed in the liquid accumulation bin, and the baffle extends in the liquid accumulation bin toward the end of the ventilator and is inclined toward the drainer.

[0019] Compared with the prior art, the technical effect achieved by adopting this technical solution is as follows: by installing a baffle in the liquid accumulation bin, the problem of the accumulated liquid flowing back to the breathing mask can be effectively solved. The baffle extends in the liquid accumulation bin toward the end of the ventilator to prevent the accumulated liquid in the liquid accumulation bin from flowing toward the breathing mask; the baffle is inclined toward the drainer to allow the accumulated liquid in the connecting pipe to flow smoothly to the liquid accumulation bin.

DETAILED DESCRIPTION

[0028] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and understandable, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0029] In order to solve the problems of unstable connection, poor sealing and easy accumulation of liquid in the existing ventilator connecting tube, this embodiment provides a connecting tube with stable connection, good sealing and capable of draining accumulated liquid.

[0030] See also Figures 1 to 5 The present embodiment provides a connecting tube for a facial respirator, wherein the connecting tube is used to connect a breathing mask and a facial respirator, wherein the connecting tube and the breathing mask are connected by threads, and the connecting tube includes a connecting tube body 10, the connecting tube body 10 is hollow inside and has a corner, and the connecting tube body 10 includes a mask end 11 and a respirator end 12.

[0031] Specifically, the connecting tube is a hollow plastic tube with a 90-degree angle. When the connecting tube connects the breathing mask and the facial respirator together, the humidified oxygen from the facial respirator will pass through the pipeline of the connecting tube body 10 to the breathing mask to provide oxygen to the patient. Among them, the mask end 11 is used to connect the breathing mask, and the respirator end 12 is used to connect the facial respirator.

[0032] Furthermore, the connecting pipe also includes a liquid accumulation component 20, which is arranged at the corner of the connecting pipe body 10, and the liquid accumulation component 20 includes a liquid accumulation bin 21 and a drainer 22; wherein the liquid accumulation bin 21 is connected to the drainer 22, and the drainer 22 can be adjusted to discharge the accumulated liquid in the liquid accumulation bin 21.

[0033] Specifically, the liquid accumulation component 20 is arranged at the corner of the connecting pipe body 10, which can better collect the liquid generated by the humidified oxygen in the connecting pipe body 10. The liquid accumulation bin 21 and the drainer 22 are connected by a slender plastic tube, and the accumulated liquid in the liquid accumulation bin 21 can flow to the drainer 22 through the slender plastic tube, and the drainer 22 controls whether to drain the liquid.

[0034] Furthermore, the connecting tube also includes an embedded component 30, which is arranged at the mask end 11, and the embedded component 30 includes a threaded tube 31 and a first inner tube 32, and the first inner tube 32 is placed inside the threaded tube 31; the breathing mask also includes a cap component 40, the cap component 40 includes a threaded cap 41 and a second inner tube 42, and the second inner tube 42 is placed inside the threaded cap 41, and the cap component 40 is arranged on the breathing mask; wherein, when the connecting tube is connected to the breathing mask, the first inner tube 32 is inserted into the second inner tube 42, and the connection tightness between the first inner tube 32 and the second inner tube 42 can be adjusted by adjusting the rotation of the threaded cap 41 on the threaded tube 31.

[0035] Specifically, the embedded component 30 is arranged on the connecting pipe, and the threaded pipe 31 is provided with an external thread; the cap component 40 is arranged on the breathing mask, and the threaded cap 41 is provided with an internal thread; when the breathing mask and the connecting pipe are connected, the threaded pipe 31 and the threaded cap 41 are connected together through the combination of the external thread and the internal thread, and the first inner pipe 32 will be inserted into the second inner pipe 42. The rotation of the threaded pipe 31 and the threaded cap 41 can control the insertion degree between the first inner pipe 32 and the second inner pipe 42. Therefore, the connection tightness between the first inner pipe 32 and the second inner pipe 42 can be adjusted by adjusting the rotation of the threaded cap 41 on the threaded pipe 31, so as to increase the connection sealing performance between the connecting pipe and the breathing mask.

[0036] Furthermore, the aperture of the first inner tube 32 gradually decreases in a direction away from the connecting tube body 10 .

[0037] Specifically, the aperture of the second inner tube 42 is uniform and unchanged, and the aperture of the first inner tube 32 gradually decreases in the direction away from the connecting tube body 10, so that when the first inner tube 32 is inserted into the second inner tube 42, there must be a point with the best sealing between the second inner tube 42 and the first inner tube 32. By providing the first inner tube 32 with a gradually decreasing aperture, the problem of poor sealing when the connecting tube is connected to the breathing mask can be effectively solved.

[0038] Furthermore, a first limit block 421 and a second limit block 422 are installed on the second inner tube 42 ; wherein the threaded cap 41 is placed between the first limit block 421 and the second limit block 422 , and the threaded cap 41 can move relative to the second inner tube 42 .

[0039] Specifically, the first limit block 421 is an annular protrusion with one side perpendicular to the second inner tube 42 and one side inclined to the second inner tube 42. The threaded cap 41 can pass through the annular protrusion through the inclined side, but will be blocked by the side perpendicular to the second inner tube 42. The second limit block 422 is an annular protrusion with two sides perpendicular to the second inner tube 42. When the movable path of the threaded cap 41 meets the second limit block 422, it will be blocked. As a result, the threaded cap 41 will be restricted between the first limit block 421 and the second limit block 422. When the threaded cap 41 is combined with the threaded tube 31, the threaded cap 41 will drive the second inner tube 42 to move through the second limit block 422. As a result, when the threaded cap 41 is fixed to the threaded tube 31, the second inner tube 42 will also be firmly fixed to the first inner tube 32 by the second limit block 422, thereby increasing the connection stability between the connecting tube and the breathing mask.

[0040] Furthermore, the drainer 22 includes a shell 221, a rubber block 223, a first elastic component 224 and a driving component 225; an installation space 222 is provided inside the shell 221, and a water inlet 2211 and a water outlet 2212 are provided on the shell 221; the rubber block 223 is placed in the installation space 222, and a through hole 2231 is provided inside the rubber block 223; the first elastic component 224 is placed in the installation space 222, and connects the shell 221 and the rubber block 223; the driving component 225 is connected to the rubber block 223, and is partially placed outside the shell 221; wherein, when the driving component 225 drives the rubber block 223 until the through hole 2231 is aligned with the water inlet 2211 and the water outlet 2212, the accumulated liquid in the liquid storage tank 21 can be discharged through the drainer 22.

[0041] Specifically, the rubber block 223 is square, and when the through hole 2231 is completely offset from the water inlet 2211 and the water outlet 2212, the rubber block 223 can completely block the water inlet 2211 and the water outlet 2212, so that the drain 22 will not leak. In addition, the through hole 2231 of the rubber block 223 is the same size as the aperture of the water inlet 2211 and the water outlet 2212.

[0042] Furthermore, a first blocking block 226 and a second blocking block 227 are also installed in the shell 221; when the rubber block 223 moves to contact the first blocking block 226, the through hole 2231 is aligned with the water inlet 2211 and the water outlet 2212; when the rubber block 223 moves to contact the second blocking block 227, the through hole 2231 is completely offset from the water inlet 2211 and the water outlet 2212.

[0043] Specifically, the first blocking block 226 is arranged on the side close to the first elastic component 224, and the second blocking block 227 is arranged on the side close to the driving component 225. When the driving component 225 drives the rubber block 223 to be blocked by the first blocking block 226, the first elastic component 224 is compressed, and the through hole 2231 is aligned with the water inlet 2211 and the water outlet 2212, and the drainer 22 can discharge liquid. When the driving component 225 stops working, the first elastic component 224 will rebound and push the rubber block 223 to contact with the second blocking block 227, and the through hole 2231 is completely offset from the water inlet 2211 and the water outlet 2212, and the drainer 22 stops discharging liquid.

[0044] Furthermore, the driving component 225 includes a driving shaft 2251 , a second elastic component 2252 and a driving head 2253 ; wherein the driving shaft 2251 connects the rubber block 223 and the driving head 2253 , and the second elastic component 2252 is disposed on the driving shaft 2251 and between the driving head 2253 and the housing 221 .

[0045] Specifically, in this embodiment, both the first elastic component 224 and the second elastic component 2252 are springs. The second elastic component 2252 is wound around the drive shaft 2251 and is disposed outside the housing 221, between the drive head 2253 and the housing 221. When the drive head 2253 is pressed to make the drive shaft 2251 push the rubber block 223, the second elastic component 2252 is compressed. When the pressing is canceled, the second elastic component 2252 will rebound, causing the drive component 225 to return to its original position, thereby increasing the operability of the discharger 22.

[0046] Furthermore, a baffle plate 211 is installed in the liquid storage bin 21 , and the baffle plate 211 extends in the liquid storage bin 21 toward the ventilator end 12 and tilts toward the drainer 22 .

[0047] Specifically, in this embodiment, the baffle plate 211 is a plastic plate, which extends from the liquid storage tank 21 toward the ventilator end 12 and is inclined toward the drain 22, and a hole is left between the liquid storage tank 21 and the connecting pipe body 10, so that the liquid in the connecting pipe body 10 can flow into the liquid storage tank 21. When the connecting pipe shakes, the baffle plate 211 can effectively prevent the accumulated liquid in the liquid storage tank 21 from flowing back into the connecting pipe body 10.

[0048] Although the utility model is disclosed as above, the utility model is not limited thereto. Any person skilled in the art can make various changes and modifications without departing from the spirit and scope of the utility model. Therefore, the protection scope of the utility model shall be subject to the scope defined by the claims.
