Description

Technical Field

[0001] The utility model relates to an oxygen humidifying device capable of preventing an oxygen inhalation tube from falling off. Background Art

[0002] At present, the connection between an oxygen humidifying bottle and an oxygen inhalation tube is prone to falling off during oxygen inhalation. For example, when the oxygen tube is too short, the oxygen tube at the patient's nostril may be pulled off during pulling, turning over, getting up, etc., seriously interfering with the reliability and safety of oxygen supply to the patient. Currently, there are only the following two connection methods for the oxygen humidifying bottle and the oxygen inhalation tube (or nasal oxygen tube) used in the market and hospitals:

[0003] First, as shown in Figure 1 , the outer wall of the air outlet joint 1-1 of the oxygen humidifying bottle 1 is conical, the inner hole of the interface sleeve 2-1 of the oxygen inhalation tube 2 is conical, and the air outlet joint 1-1 and the interface sleeve 2-1 are hermetically fixed through conical surface fitting. However, due to the smooth fitting surface, the frictional resistance is very small and it is extremely easy to fall off;

[0004] Second, as shown in Figure 2 , barbs K are provided on the outer conical surface of the air outlet joint 1-1 of the oxygen humidifying bottle 1, the inner hole of the interface sleeve 2-1 of the oxygen inhalation tube 2 is conical, and the barbs K of the air outlet joint 1-1 are inserted on the inner conical surface of the interface sleeve 2-1 to achieve fixation. Compared with the first method, it can increase a certain frictional resistance. However, since the interface sleeve 2-1 is elastic, it will still separate when a large pulling force is applied. At the same time, the effective sealing mating conical surface at the connection will be reduced, the gap will become larger, and it is easy to leak air when it is loosened and deformed by pulling. At the same time, the interface sleeve is greatly deformed by extrusion and it is very laborious to put it on.

[0005] Therefore, the anti-detachment performance of the above two existing methods at the connection between the oxygen humidifying bottle and the oxygen inhalation tube is not ideal and needs to be further improved.

[0006] In addition, when the ventilation pipe in the existing oxygen humidifying bottle directly discharges oxygen into the purified water in the bottle body, due to the large air pressure, large bubbles will be generated, resulting in a very large noise problem, which will cause an adverse noise interference to the patient's rest and sleep; at the same time, due to pipeline pollution during the oxygen supply process, when oxygen enters the oxygen humidifying bottle, it may bring problems such as dust, bacteria or viruses and other impurities. Content of the Utility Model

[0007] The present invention provides an oxygen humidifying device capable of preventing an oxygen inhalation tube from falling off, so as to solve the technical problem that the anti-detachment performance at the connection between the oxygen humidifying bottle and the oxygen inhalation tube in the prior art is not ideal and needs to be further optimized and improved.

[0008] In order to achieve the above-mentioned purpose, the solution of the present invention is: an oxygen humidification device that can prevent the oxygen inhalation tube from falling off, comprising an oxygen humidification bottle and an oxygen inhalation tube, wherein the gas outlet joint of the oxygen humidification bottle is connected to the interface sleeve of the oxygen inhalation tube, and is characterized in that: an external thread section and an external conical surface section are provided on the outer wall of the gas outlet joint; a threaded hole section and a conical hole section are provided on the inner wall of the interface sleeve; the external thread section is fixedly matched with the threaded hole section; and the outer conical surface section is sealedly matched with the conical hole section.

[0009] With this solution, the outlet connector of the oxygen humidifier bottle is mated and connected to the interface sleeve of the oxygen inhalation tube during use. The outer conical surface of the outlet connector and the tapered hole section of the interface sleeve mate to form an effective seal, while the outer threaded section of the outlet connector and the threaded hole section of the interface sleeve threadably engage to securely secure the connection.

[0010] Because the outer conical section and the tapered hole section of the interface sleeve are perfectly tapered together, an effective seal is formed, thereby achieving a gapless fit and less prone to air leakage. At the same time, because the outer thread section of the outlet connector and the threaded hole section of the interface sleeve are threaded together, a firm fixation is achieved. Since only axial tension is generated between the interface sleeve and the outlet connector of the oxygen humidifier bottle when the patient pulls the oxygen tube, and no rotation occurs between them, the outer thread section and the threaded hole section remain in a screwed state and the engagement is stable. Even if the interface sleeve is elastic, they will not separate from each other. Compared with the first and second solutions in the prior art, this technical solution can improve the anti-detachment performance of the connection between the oxygen humidifier bottle and the oxygen tube. In addition, when the oxygen tube is pulled out, the deformation of the interface sleeve is smaller, and it is less likely to loosen, thereby improving the sealing performance. The operation is also simple when it is screwed on and off.

[0011] Furthermore, the threaded hole section and the external thread section may be screwed together for at least three turns.

[0012] Furthermore, the engagement length between the threaded hole section and the external thread section is at least 5 mm.

[0013] Furthermore, the lower end of the ventilation tube in the oxygen humidification bottle is connected to the pressure relief bottle; the ratio of the inner diameter of the pressure relief bottle to the inner diameter of the ventilation tube is greater than; an annular groove is provided on the middle side wall of the pressure relief bottle, and a filter element is mounted on the annular groove; a plurality of exhaust holes are provided in the annular groove along the circumferential direction and connected to the interior of the pressure relief bottle.

[0014] Furthermore, the pressure relief bottle is made of sound insulation material.

[0015] Furthermore, the bottle mouth of the pressure relief bottle and the lower end of the ventilation pipe are detachably fixed.

[0016] Furthermore, the inner diameter of the exhaust hole is 0.5-1 mm.

[0017] Advantages of the present utility model:

[0018] First, due to the complete conical surface fit between the outer conical surface section of the gas outlet joint of the oxygen humidifying bottle and the conical hole section of the interface sleeve of the oxygen inhalation tube, an effective seal is formed, thus achieving a gapless fit and making it not easy to have air leakage problems. At the same time, due to the screw thread engagement between the external thread section of the gas outlet joint and the threaded hole section of the interface sleeve of the oxygen inhalation tube, a firm fixation is achieved. Since only axial tension is generated between the interface sleeve and the gas outlet joint of the oxygen humidifying bottle when the patient pulls the oxygen inhalation tube and they do not rotate relative to each other, the external thread section and the threaded hole section still remain in a screwed state and the engagement is stable. Even if the interface sleeve has elasticity, they will not disengage from each other.

[0019] Second, compared with the first and second solutions in the prior art, the present utility model can significantly improve the anti - detachment performance at the connection between the oxygen humidifying bottle and the oxygen inhalation tube. In addition, when the oxygen inhalation tube is pulled outwards, the deformation amount of the interface sleeve is smaller, making it not easy to loosen and improving the sealing performance. At the same time, when installing and removing by screwing, the operation is also simple.

[0020] Third, due to the sufficient number of screw - engagement turns and screw - engagement length between the gas outlet joint of the oxygen humidifying bottle and the interface sleeve of the oxygen inhalation tube, the friction force is large and the pre - tightening force is sufficient, which can improve the anti - detachment and sealing performance, and the work is more stable and reliable.

[0021] Fourth, by arranging a pressure - relief bottle in the ventilation pipe inside the oxygen humidifying bottle, and the ratio of the inner diameter of the pressure - relief bottle to the inner diameter of the ventilation pipe is greater than 2. When high - pressure oxygen enters the pressure - relief bottle from the ventilation pipe, it will relieve pressure, and the oxygen will go out through the exhaust hole and then be filtered by the filter element to produce very small low - pressure bubbles when discharged. This can not only reduce the noise but also achieve the oxygen filtration treatment. Therefore, the combined problems of large noise and unclean oxygen can be solved simultaneously. In addition, when the oxygen relieves pressure, it is more difficult for tiny impurities to escape from the filter element, making the filtering effect better. Description of the Drawings

[0032] The present utility model will be further described below in conjunction with the drawings and embodiments:

[0033] Embodiment 1: Refer to Figures 3 - 5 , an oxygen humidifying device that can prevent the oxygen inhalation tube from falling off, including an oxygen humidifying bottle 1 and an oxygen inhalation tube 2; and the oxygen humidifying bottle 1 contains existing structures such as a bottle body 1-3, a bottle cap 1-4, a ventilation pipe 1-2, an air inlet joint 1-5, a regulating valve 1-6, a flow meter 1-7, etc.; the air outlet joint 1-1 of the oxygen humidifying bottle 1 is used to connect with the interface sleeve 2-1 of the oxygen inhalation tube 2. The difference in this embodiment is:

[0034] An external thread section 1-11 and an external conical surface section 1-12 are provided on the outer wall of the air outlet joint 1-1; a threaded hole section 2-11 and a conical hole section 2-12 are provided on the inner wall of the interface sleeve 2-1; the external thread section 1-11 is fixedly fitted with the threaded hole section 2-11; the external conical surface section 1-12 is hermetically fitted with the conical hole section 2-12.

[0035] During the use of the product in this embodiment, the air outlet joint 1-1 of the oxygen humidifying bottle 1 is cooperatively connected with the interface sleeve 2-1 of the oxygen inhalation tube 2. Refer to Figures 5 - 7 , an effective seal is formed by the conical surface fit between the external conical surface section 1-12 of the air outlet joint 1-1 and the conical hole section 2-12 of the interface sleeve 2-1; and a firm fixation is achieved by the screw thread engagement between the external thread section 1-11 of the air outlet joint 1-1 and the threaded hole section 2-11 of the interface sleeve 2-1. The analysis of its performance characteristics is as follows:

[0036] Since the outer conical surface section 1-12 and the conical hole section 2-12 of the interface sleeve 2-1 are in complete conical surface fit to form an effective seal, and then a gapless fit is achieved, it is not easy to have an air leakage problem. For details, see Figures 5 - 7 ; at the same time, since the external thread section 1-11 of the gas outlet joint 1-1 and the threaded hole section 2-11 of the interface sleeve 2-1 are in threaded engagement, firm fixation is achieved. For details, see Figures 5 - 7 , and since only axial tension is generated between the interface sleeve 2-1 and the gas outlet joint 1-1 of the oxygen humidifying bottle 1 when the patient pulls the oxygen inhalation tube 2 and they do not rotate relative to each other, the external thread section 1-11 and the threaded hole section 2-11 still remain in a screwed state and the engagement is stable. Even if the interface sleeve 2-1 is elastic, they will not disengage from each other. Compared with the first (see Figure 1 ) and the second solutions (see Figure 2 ) in the prior art, the technical solution of this embodiment can significantly improve the anti-disengagement performance of the connection between the gas outlet joint 1-1 of the oxygen humidifying bottle 1 and the interface sleeve 2-1 of the oxygen inhalation tube 2; in addition, when the oxygen inhalation tube 2 is pulled outwards, the overall deformation of the interface sleeve 2-1 will be smaller, and it is not easy to loosen, thus improving the sealing performance; this embodiment is installed and removed by screwing, and the operation is also very simple.

[0037] For details, see Figure 5 , when in use, pure water is filled in the oxygen humidifying bottle 1, the air inlet joint 1-5 is connected to the hospital central oxygen supply system or an oxygen cylinder in place, the interface sleeve 2-1 of the oxygen inhalation tube 2 is connected to the gas outlet joint 1-1 of the oxygen humidifying bottle 1 in place, then the regulating valve 1-6 is opened and adjusted to a reasonable flow rate, and then the nasal cannula of the oxygen inhalation tube 2 is inserted into the patient's nasal cavity.

[0038] Furthermore, at least 3 turns can be screwed between the threaded hole section 2-11 and the external thread section 1-11. The more the number of screwed turns, the greater the friction force, and the corresponding pre-tightening force will also increase, improving the anti-disengagement and sealing performance, and the work is more stable and reliable.

[0039] Preferably, 3-10 turns are screwed between the threaded hole section 2-11 and the external thread section 1-11.

[0040] Furthermore, the screwed length between the threaded hole section 2-11 and the external thread section 1-11 is at least 5 mm. The greater the screwed length, the greater the friction force, and the corresponding pre-tightening force will also increase, improving the anti-disengagement and sealing performance, and the work is more stable and reliable.

[0041] Preferably, the screwed length between the threaded hole section 2-11 and the external thread section 1-11 is 5-15 mm.

[0042] Specifically, the oxygen inhalation tube (or nasal oxygen tube) is a medical supply made of soft polyvinyl chloride and silicone rubber, which consists of an interface sleeve, a tube, a nasal plug, etc. It is soft and not prone to wrinkling.

[0043] In this embodiment, the structure of the interface sleeve of the oxygen inhalation tube is different from the existing structure; other parts are the same as the existing structure.

[0044] Embodiment 2: This embodiment is a further improvement based on Embodiment 1:

[0045] See Figures 8 - 10 , the lower end of the ventilation pipe 1-2 in the oxygen humidifying bottle 1 is connected to the pressure relief bottle 3; the inner diameter ratio of the pressure relief bottle 3 to the inner diameter of the ventilation pipe 1-2 is greater than 2; a ring groove 3-1 is provided on the middle side wall of the pressure relief bottle 3, and a filter element 4 is sleeved on the ring groove 3-1; a plurality of exhaust holes 3-2 communicating with the inside of the pressure relief bottle 3 are provided along the circumferential direction in the ring groove 3-1. Since the inner diameter ratio of the pressure relief bottle 3 to the inner diameter of the ventilation pipe 1-2 is greater than 2; when oxygen with a higher pressure enters the pressure relief bottle 3 from the ventilation pipe 1-2, pressure relief will occur. Due to the decrease in pressure, when the oxygen exits through the exhaust holes 3-2 and is filtered by the filter element 4 and then discharged, very small low-pressure bubbles are generated, which can not only reduce noise but also achieve oxygen filtration. Therefore, the combined problems of high noise and unclean oxygen can be solved simultaneously. In addition, when the oxygen is pressure-relieved, it is more difficult for tiny impurities to escape from the filter element, so the filtering effect will be better; at the same time, the oxygen humidity is higher, which does not affect the patient's rest.

[0046] Preferably, the inner diameter ratio of the pressure relief bottle 3 to the inner diameter of the ventilation pipe 1-2 is 2-6.

[0047] Furthermore, the pressure relief bottle 3 is made of sound insulation materials (such as sound insulation glass, etc.). It can further reduce the noise generated during the process of oxygen entering the pressure relief bottle 3 and being discharged and filtered, achieving silent oxygen inhalation.

[0048] Furthermore, the bottle mouth 3-3 of the pressure relief bottle 3 is detachably fixed to the lower end of the ventilation pipe 1-2. The pressure relief bottle 3 can be detachably replaced and disinfected. In this embodiment, the bottle mouth 3-3 of the pressure relief bottle 3 is in threaded fit with the lower end of the ventilation pipe 1-2 to achieve detachable fixation.

[0049] Furthermore, the inner diameter of the exhaust hole 3-2 is 0.5-1 mm.

[0050] Preferably, the filter element 4 is made of filter cotton or polytetrafluoroethylene filter membrane, etc., which can remove particles above 0.5 um, and the filtration rate should not be less than 90%.

[0051] In other embodiments, specifically, the filter element 4 can be any existing known filter element that meets medical requirements.

[0052] The preferred specific embodiments of the present utility model have been described in detail above. It should be understood that those of ordinary skill in the art can make many modifications and variations based on the concept of the present utility model without creative efforts. Therefore, all technical solutions that can be obtained by those skilled in the art in the technical field based on the concept of the present utility model through logical analysis, reasoning, or limited experiments on the basis of the prior art shall fall within the protection scope determined by the claims.
