Description

Technical Field

[0001] The utility model belongs to the field of medical equipment, and particularly relates to an oxygen battery mounting base. Background Art

[0002] An oxygen battery, also known as an oxygen concentration sensor, is usually used in conjunction with a ventilator to measure the oxygen concentration in the mixed gas inhaled by a patient. The traditional method is to directly install the oxygen battery on the inspiratory pipeline between the patient and the air-oxygen mixer, and ensure that the oxygen battery is connected to the inspiratory pipeline. When the mixed gas passes through the inspiratory pipeline, the oxygen battery can monitor it, and then the oxygen concentration value in the mixed air can be obtained.

[0003] Since the distance between the ventilator and the patient is not a straight line, the inspiratory pipeline will be bent and deformed to varying degrees when connected to the patient. Because the oxygen battery is connected to the inspiratory pipeline, the oxygen battery will be deformed, affecting the monitoring accuracy of the oxygen concentration. Summary of the Utility Model

[0004] The utility model aims to provide an oxygen battery mounting base to solve the problem in the prior art that the deformation of the inspiratory pipeline causes the deformation of the oxygen battery, resulting in a decrease in the measurement accuracy of the oxygen concentration.

[0005] To achieve the above object, the technical solution adopted by the utility model is as follows:

[0006] An oxygen battery mounting base includes a base for fixing the oxygen battery. An air passage is arranged inside the base. A through hole for accommodating the detection end of the oxygen battery is arranged on the base, and the through hole is arranged in a penetrating manner with the air passage. A first connecting pipe for connecting with the inspiratory pipeline is arranged at the air inlet end of the base, and a second connecting pipe for connecting with the inspiratory pipeline is arranged at the air outlet end of the base. The first connecting pipe and the base, and the second connecting pipe and the base are both hermetically connected. The interiors of the first connecting pipe and the second connecting pipe are hollow and both are communicated with the air passage.

[0007] As a limitation to the utility model: The second connecting pipe is sleeved on the air outlet end of the base and can rotate around the axis of the base.

[0008] As a further limitation to the utility model: The second connecting pipe includes a first sub-pipe, a second sub-pipe and a third sub-pipe that are fixedly and hermetically connected in sequence. The first sub-pipe is hermetically rotatably sleeved on the air outlet end of the base. The second sub-pipe is a bent pipe structure. The third sub-pipe is used for connecting with the inspiratory pipeline.

[0009] As a further limitation to the utility model: A sliding groove is arranged on the first sub-pipe along its circumferential direction. The sliding groove is recessed towards the axis of the base. A limiting member is detachably arranged at the position corresponding to the sliding groove on the base, and the limiting member extends into the sliding groove.

[0010] As a further limitation of the present utility model: A sealing ring is provided between the first branch pipe and the base, and the sealing ring is sleeved on the outer diameter of the first branch pipe.

[0011] As a further limitation of the present utility model: The taper of the third branch pipe is 1:40, and the minimum diameter end is arranged away from the base.

[0012] As a further limitation of the present utility model: A boss is provided at one end of the base close to the second connecting pipe. The boss extends radially along the base. The limiting member passes through the boss and extends into the sliding groove. A positioning member is also detachably provided on the base. A clamping space for clamping the cover plate of the ventilator is formed among the positioning member, the base and the boss.

[0013] As a further limitation of the present utility model: The positioning member is a nut, and the nut is sleeved on the outer diameter of the base and is threadedly connected with the base.

[0014] As another limitation of the present utility model: The surface of the base close to the oxygen battery is a plane, and the through hole is arranged on the plane. The axis of the through hole is perpendicular to the axis of the base.

[0015] As a further limitation of the present utility model: The first connecting pipe is detachably connected with the base. The end of the first connecting pipe away from the base is provided with a conical opening, and the minimum diameter end is arranged away from the base.

[0016] Due to the adoption of the above technical solution, the beneficial effects obtained by the present utility model compared with the prior art are as follows:

[0017] (1) The present utility model includes a base, a first connecting pipe and a second connecting pipe. An air passing channel is arranged inside the base. The oxygen battery is fixed on the base. A through hole communicating with the air passing channel is arranged on the base. The detection end of the oxygen battery is located in the through hole. When the mixed gas passes through the air passing channel, the oxygen battery can detect the oxygen concentration value in the mixed gas. In the present utility model, the oxygen battery is fixed on the base instead of being directly installed on the suction pipeline. When the suction pipeline is bent, the oxygen battery will not be deformed, improving the monitoring accuracy.

[0018] (2) In the prior art, the distance between the ventilator and the patient is not a straight line. When the suction pipeline is inserted into the patient's mouth and nose, the suction pipeline may be bent or even folded into a dead bend, which may cause the patient to suffocate in severe cases. In the present utility model, the second connecting pipe is sleeved on the air outlet end of the base and can rotate 360° around the axis of the base to achieve multi-angle rotation. Moreover, the second branch pipe in the second connecting pipe is a bent pipe structure. During use, it can ensure that the suction pipeline connected to the second connecting pipe rotates flexibly, avoiding knotting.

[0019] (3) When the present utility model is installed, the base passes through the cover plate of the ventilator, the boss and the second connecting pipe are located outside the ventilator, the oxygen battery, the positioning member, and the first connecting pipe are located inside the ventilator, and the cover plate of the ventilator is clamped between the boss and the positioning member. In the traditional method, the oxygen battery is fixed on the air intake pipeline. The oxygen battery is far from the ventilator, with a long adjustment period and a long response time. During the response time of the ventilator, the patient continuously inhales the unqualified mixed gas. However, with this setting method, the oxygen battery is closer to the ventilator. If the oxygen concentration value in the mixed gas is inappropriate, it can be adjusted in time with a short adjustment period.

[0020] In summary, the present utility model can avoid the problem that the monitoring accuracy of the oxygen battery is reduced due to the deformation of the air intake pipeline, and can flexibly adjust the direction of the air intake pipeline to avoid knotting. At the same time, when the oxygen concentration does not meet the standard, the adjustment period can be shortened; the present utility model is applicable to clinical medicine and is used to fix the oxygen battery.

[0037] The preferred embodiments of the present utility model will be described below with reference to the accompanying drawings. It should be understood that the oxygen battery mounting seat described herein is a preferred embodiment, which is only used to illustrate and explain the present utility model and does not constitute a limitation to the present utility model.

[0038] The orientation terms or positional relationships such as "upper", "lower", "left", "right", etc. described in the embodiments are based on the orientation relationship in the accompanying drawings of the specification of the present utility model Figure 4 and are only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element must have a specific orientation, be constructed and operated in a specific orientation, and thus cannot be construed as a limitation to the content protected by the present utility model.

[0039] As Figures 1 - 10 shown, this embodiment includes a base 2 for fixing the oxygen battery 1. An air passage 21 is provided inside the base 2. A through hole 22 for accommodating the detection end of the oxygen battery 1 is provided on the base 2, and the through hole 22 is arranged in a penetrating manner with the air passage 21; a first connecting pipe 3 for connecting with an inlet pipe is provided at the intake end 23 of the base 2, and a second connecting pipe 4 for connecting with the suction pipe 7 is provided at the outlet end 24 of the base 2. Both the first connecting pipe 3 and the base 2, and the second connecting pipe 4 and the base 2 are hermetically connected. The interiors of the first connecting pipe 3 and the second connecting pipe 4 are hollow and both are communicated with the air passage 21.

[0040] Specifically, as Figures 1 - 4As shown, in this embodiment, the base 2 has a cylindrical structure. A plane is cut out at its upper end, and the through hole 22 is opened on this plane. The axis of the through hole 22 is in the up and down direction, and the axis of the base 2 is in the left and right direction. The two axes are perpendicular. Here, the meaning of the through hole 22 is that it penetrates the wall of the base, not that it radially penetrates the entire base 2 along the base 2. In this embodiment, the through hole 22 is an internal threaded hole, and the oxygen battery 1 is threadedly connected to the through hole 22. When replacing the oxygen battery 1 later, the operation is simple and no special tool is required. The structure of the plane increases the contact area between the oxygen battery 1 and the base 2, ensuring that the oxygen battery 1 is fixed more stably. Of course, any method in the prior art can also be used to fix the oxygen battery 1 on the base 2, such as snap connection or plug connection. After the oxygen battery 1 is fixed, its detection end is located in the through hole 22. When the mixed gas flows from left to right in the gas passage 21, the oxygen battery 1 can monitor its oxygen concentration value.

[0041] In order to fix this embodiment on the cover plate of the ventilator, a boss 26 and a positioning member are provided on the base 2, such as Figure 1 、 2 shown, a boss 26 is fixedly provided at the right end of the base 2. In this embodiment, the boss 26 has a cylindrical structure and is integrally provided with the base 2. The boss 26 extends radially along the base 2, that is, the boss 26 is coaxial with the base 2 and the diameter of the boss 26 is greater than the diameter of the base 2. In this embodiment, the positioning member is a nut 6. An external thread is provided on the outer diameter of the base 2, Figures 1 - 4 、the external threads on the base 2 in 6 - 10 are not shown. The nut 6 is sleeved on the outer diameter of the base 2 and is threadedly connected to the base 2. There is a clamping space 8 for clamping the cover plate of the ventilator between the nut 6, the base 2 and the boss 26. Refer to Figure 1 , during installation, a connection hole is opened on the cover plate of the ventilator, and one end of the first connection pipe 3 in this embodiment is passed through the connection hole. The diameter of the connection hole is smaller than the diameter of the boss 26. Therefore, this embodiment stops when it moves to the point where the boss 26 contacts the cover plate. Then, the nut 6 is sleeved from one end of the first connection pipe 3 and the nut 6 is rotated. The nut 6 moves to the right until the nut 6 and the boss 26 clamp the cover plate. After this embodiment is fixed, the boss 26 and the second connection pipe 4 are located outside the ventilator, and the oxygen battery 1, the nut 6, and the first connection pipe 3 are located inside the ventilator. The cover plate of the ventilator is clamped between the boss 26 and the nut 6. After this embodiment is fixed, the oxygen battery 1 is close to the ventilator, that is, the oxygen battery 1 is close to the air - oxygen mixer. If the oxygen concentration value in the suction pipe 7 does not meet the standard, it can be adjusted in time, shortening the adjustment cycle and preventing the patient from inhaling gas with an unqualified oxygen concentration for a long time.

[0042] In this embodiment, the boss 26 can also be replaced with another structure, such as arranging a plurality of convex blocks at intervals along the axial direction of the base 2. In this embodiment, the positioning member can also be replaced with any structure in the prior art, as long as it is ensured that the boss 26 and the positioning member can clamp the cover plate between them to achieve fixation.

[0043] The second connecting pipe 4 is sleeved on the air outlet end 24 of the base 2 and can rotate around the axis of the base 2. As Figures 2 - 4 shown, the second connecting pipe 4 includes a first sub-pipe 41, a second sub-pipe 42 and a third sub-pipe 43 that are fixedly and hermetically connected in sequence from left to right.

[0044] As Figure 4 , 5 shown, the first sub-pipe 41 is hermetically rotatably sleeved on the air outlet end 24 of the base 2. The way of rotatable sleeving is as follows: a chute 411 is arranged on the first sub-pipe 41 along its circumferential direction. The chute 411 is recessed towards the axis of the base 2, forming a U-shape at the top of the first sub-pipe 41 and an inverted U-shape at the bottom of the first sub-pipe 41. A limiting member is detachably arranged at the position corresponding to the chute 411 on the base 2. In this embodiment, the limiting member is a ball screw 25 in the prior art. The ball screw 25 passes through the boss 26 and extends into the chute 411. The structure of the ball screw 25 is in the prior art and will not be elaborated here. Of course, the ball screw 25 in this embodiment can also be replaced with a setscrew in the prior art. However, it should be noted that the setscrew cannot tightly press against the first sub-pipe 41 to ensure that the first sub-pipe 41 can rotate. Or, in this embodiment, the first sub-pipe 41 and the base 2 can also be rotatably connected in another way. For example, a bearing is fixedly sleeved on the first sub-pipe 41, and the outer ring of the bearing is fixed to the base 2. The sealing method is as follows: a sealing ring 5 is arranged between the first sub-pipe 41 and the base 2. A groove 412 is formed along the circumferential direction at the left end of the first sub-pipe 41. The sealing ring 5 is sleeved on the outer diameter of the first sub-pipe 41 and is clamped in the groove 412. In this embodiment, the sealing ring 5 is a silicone O-ring. The diameter of the silicone O-ring is larger than the depth of the groove 412. In other words, after the first sub-pipe 41 is sleeved in the base 2, the silicone O-ring is in a compressed state to achieve elastic sealing. Of course, the sealing ring 5 in this embodiment can also be a Y-ring or other sealing rings as long as dynamic sealing can be achieved.

[0045] As Figures 2 - 7 shown, the second sub-pipe 42 is a bent pipe structure for changing the direction of the pipeline. In this embodiment, the bending angle of the second sub-pipe 42 is 135°. Of course, it can also be set to other angles according to needs. The third sub-pipe 43 is used to connect with the suction pipe 7. As Figure 8 , 9 shown, since the suction pipe 7 is a plastic pipe or a rubber pipe for the patient to inhale, it is necessary to ensure the sealing between the suction pipe 7 and the third sub-pipe 43, and it is also necessary to facilitate insertion and extraction to replace the suction pipe 7. For this reason, it is necessary to meet the industry standard of YY / T1040.1-2015. Therefore, the taper of the third sub-pipe 43 in this embodiment is set to 1:40, and the minimum diameter end is arranged away from the base 2. As Figure 10As shown, in this embodiment, D1 = 22.5 mm, D2 = 22.02 mm, H = 19.01 mm, and the taper C = (D1 - D2) / H = 1 / 40. This tapered section is the joint end of the third branch pipe 43. During installation, the suction pipe 7 is sleeved on the joint end of the third branch pipe 43.

[0046] As Figure 7 shown, the first connecting pipe 3 is sleeved on the left end of the base 2 and is threadedly connected to the base 2. It should be noted that in this embodiment, before screwing the first connecting pipe 3 into the base 2, sealant is first applied to the thread, and then the first connecting pipe 3 is screwed in through the thread to achieve the sealing effect. Of course, the connection between the first connecting pipe 3 and the base 2 can also be achieved by any method in the prior art. Similarly, the sealing between the two can also be achieved by any other method in the prior art.

[0047] As Figure 3 、 4 shown, the end of the first connecting pipe 3 away from the base 2 is provided with a tapered opening, and the minimum diameter end is arranged away from the base 2. The first connecting pipe 3 is used to connect the intake pipe, and the intake pipe is also a plastic pipe or a rubber pipe. Since the intake pipe is located inside the ventilator and does not need to be frequently inserted and removed, only the first connecting pipe 3 needs to be provided with a tapered opening, and sealing can be achieved when the intake pipe is inserted from left to right. There is no need to set it to the taper specified in the YY / T 1040.1 - 2015 industry standard.

[0048] This embodiment is entirely made of hard materials, which can be aluminum or hard plastic, and has a certain strength. The base 2, the first connecting pipe 3, and the second connecting pipe 4 are all processed by injection molding and integrally formed, with less processing difficulty, higher precision, and lower cost. In addition, this embodiment has fewer components and is simple to install.

[0049] When using this embodiment, pass the first connecting pipe 3 and the base 2 in this embodiment through the connection holes previously opened on the ventilator cover plate, and then tighten the nut 6 from inside the ventilator. The nut 6 and the boss 26 clamp the cover plate to fix this embodiment; then threadedly fix the oxygen battery 1 in the through hole 22, connect the intake pipe to the first connecting pipe 3, connect one end of the suction pipe 7 to the third branch pipe 43, and insert the other end into the patient's mouth and nose. If the patient's position is higher or lower than the ventilator, the suction pipe 7 may be bent. Refer to Figure 8 , at this time, the second connecting pipe 4 can be flexibly rotated to adjust the position of the suction pipe 7. Refer to Figure 9 , to avoid the situation where the suction pipe 7 is bent, resulting in the patient's breathing difficulties or even suffocation. After adjusting to the appropriate position, the ball screw 25 can be made to press against the first branch pipe 41, and at this time, the second connecting pipe 4 cannot be rotated anymore. In addition, since the oxygen battery 1 is fixed on the base 2 rather than directly installed on the suction pipe 7 path, the oxygen battery 1 will not be deformed when the suction pipe 7 is bent, improving the monitoring accuracy.

[0050] It should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
