Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of medical devices, and particularly relates to an anesthetic breathing circuit connecting device. Background Art
[0002] The breathing circuit is the connecting part between the anesthetic machine and the patient, and is used to transfer oxygen and carbon dioxide. The design and use of the breathing circuit are crucial for the patient's respiratory treatment.
[0003] At present, the existing breathing circuits on the market are directly connected by a corrugated tube (or called a bellows tube, which can be telescopically extended) and a right-angle joint of a right-angle interface component (connecting to the anesthetic machine), without a fixing system. If the connection is not tight or the corrugated tube is pulled, etc., it is easy to cause the corrugated tube and the right-angle joint to disengage, that is, the breathing circuit is disconnected. When the breathing circuit is disconnected or separated, it will lead to insufficient ventilation, resulting in chronic severe hypoxia and carbon dioxide accumulation in the patient's body. If the alarm system of the anesthetic machine fails or the anesthesiologist fails to recognize and handle this situation in time, serious consequences such as cardiac arrest may occur. Content of the Utility Model
[0004] The technical problem to be solved by the utility model is to overcome the deficiencies of the existing technology and provide an anesthetic breathing circuit connecting device.
[0005] To solve the above technical problem, the utility model discloses an anesthetic breathing circuit connecting device, which includes a corrugated tube and a right-angle joint. One end of the right-angle joint is provided with a sleeve part, and one end of the corrugated tube is provided with an insertion part that can be inserted into the sleeve part. An activity outer sleeve is installed on the outer side of one of the insertion part and the sleeve part. The activity outer sleeve is provided with an internal thread hole, and an external thread part is provided on the outer side of the other of the insertion part and the sleeve part. The internal thread hole is connected to the external thread part to prevent the corrugated tube and the right-angle joint from disengaging.
[0006] Further, the activity outer sleeve is rotatably installed on the insertion part, the external thread part is arranged at the end of the sleeve part, and a limiting part for limiting the activity outer sleeve is arranged on the insertion part.
[0007] Further, the limiting part is a limiting outer ring arranged on the insertion part, and one end of the internal thread hole of the activity outer sleeve is provided with an internal limiting part that abuts against the limiting outer ring.
[0008] Further, the internal limiting part includes at least one arc-shaped clamping plate. One side of the arc-shaped clamping plate is fixedly connected to the activity outer sleeve, and the other side extends radially towards the internal thread hole.
[0009] Further, the arc-shaped clamping plates are two symmetrically arranged, and one side of the arc-shaped clamping plate is connected to the activity outer sleeve by screws.
[0010] Further, at least one hanging ear for hanging connection is arranged on the intubation part.
[0011] Further, it further includes a first fixing band and a second fixing band respectively connected to the two hanging ears, a rough surface of a tear sticker is arranged on the first fixing band, and a hook surface of a tear sticker is arranged on the second fixing band.
[0012] Further, it further includes a first fixing band and a second fixing band respectively connected to the two hanging ears, a plurality of clamping holes are arranged on the first fixing band, and a plurality of clamping protrusions that are clamped into the clamping holes by extrusion deformation are arranged on the second fixing band.
[0013] Compared with the prior art, the advantages of the present utility model are as follows:
[0014] In the present utility model, the inner threaded hole is connected to the external threaded part, and then the sleeve part and the intubation part are firmly connected together. Even when encountering a relatively large pulling force, it is very difficult for the sleeve part and the intubation part to break away, thereby avoiding problems such as the disconnection or disconnection of the breathing circuit leading to insufficient ventilation, chronic severe hypoxia and carbon dioxide accumulation in the patient's body, and avoiding the occurrence of medical accidents.

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0020] To facilitate the understanding of the present utility model, the following will describe the present utility model in a more comprehensive and detailed manner in conjunction with the accompanying drawings of the specification and preferred embodiments, but the protection scope of the present utility model is not limited to the following specific embodiments.
[0021] Embodiment 1:
[0022] As Figure 1 shown, the utility model discloses an anesthetic breathing circuit connection device, which includes a corrugated tube 1 and a right-angle joint 2, both of which are plastic structures. One end of the right-angle joint 2 is provided with a sleeve part 21, and one end of the corrugated tube 1 is provided with an insertion part 11 that can be inserted into the sleeve part 21. An activity outer sleeve 3 is installed on the outer side of one of the insertion part 11 and the sleeve part 21. The activity outer sleeve 3 is provided with an internal thread hole 31, and an external thread part 4 is provided on the outer side of the other of the insertion part 11 and the sleeve part 21. The internal thread hole 31 is connected to the external thread part 4 to prevent the corrugated tube 1 and the right-angle joint 2 from detaching. Thus, by the rotational connection of the internal thread hole 31 and the external thread part 4, the sleeve part 21 and the insertion part 11 are firmly connected together. Even when encountering a relatively large pulling force, it is very difficult for the sleeve part 21 and the insertion part 11 to detach, thereby avoiding problems such as the disconnection or disengagement of the breathing circuit leading to insufficient ventilation, chronic severe hypoxia and carbon dioxide accumulation in the patient's body, and avoiding the occurrence of medical accidents.
[0023] In this embodiment, the activity outer sleeve 3 is rotatably installed on the insertion part 11. The external thread part 4 is arranged at the end of the sleeve part 21, and a limiting part for limiting the activity outer sleeve 3 is arranged on the insertion part 11. Thus, the limiting part prevents the activity outer sleeve 3 from detaching from the insertion part 11. Among them, the limiting part can adopt various limiting structures. Specifically, the limiting part is a limiting outer ring 111 arranged on the insertion part 11, so as to form a T-shaped structure with the insertion part 11. One end of the internal thread hole 31 of the activity outer sleeve 3 is provided with an internal limiting part that abuts against the limiting outer ring 111. The internal limiting part can be a ring structure extending towards the center of the internal thread hole 31. There is a gap between the ring structure and the insertion part 11, which can rotate freely and can move a certain distance left and right, but cannot detach from the insertion part 11.
[0024] In this embodiment, at least one hanging part 112 for hanging is arranged on the insertion part 11. Through the inner hole part of the hanging part 112, the entire corrugated tube 1 and the right-angle joint 2 can be hung up to avoid sagging and interfering with nursing or bending. In order to improve the binding efficiency of the hanging part 112, it further includes a first fixing band 5 and a second fixing band 6 respectively connected to the two hanging parts 112. The first fixing band 5 and the second fixing band 6 are made of relatively soft plastic structures and can have a certain elastic deformation. A plurality of clamping holes 51 are arranged on the first fixing band 5, and a plurality of clamping protrusions 61 that are clamped into the clamping holes 51 by extrusion deformation are arranged on the second fixing band 6. Thus, the first fixing band 5 and the second fixing band 6 can form a fixing ring structure for fixing the corrugated tube 1. Optionally, the first fixing band 5 and the second fixing band 6 are made of flexible cloth strips. The first fixing band 5 is provided with a tearing sticker rough surface, and the second fixing band 6 is provided with a tearing sticker hook surface, which can also achieve quick binding and fixing.
[0025] Embodiment Two:
[0026] As Figure 2 shown, the main structures of the threaded pipe 1 and the right-angle joint 2 are basically the same as those in the first embodiment. The difference is that in this embodiment, in order to facilitate the installation and disassembly of the movable outer sleeve 3, the inner limiting portion is a split and detachable structure. The inner limiting portion includes at least one arc-shaped clamping plate 32. One side of the arc-shaped clamping plate 32 is fixedly connected to the movable outer sleeve 3, and the other side extends radially inward into the internal thread hole 31. Specifically, there are two symmetrically arranged arc-shaped clamping plates 32. One side of the arc-shaped clamping plate 32 is connected to the movable outer sleeve 3 by screws 33. During installation, the movable outer sleeve 3 is sleeved onto the insertion pipe portion 11, and then the arc-shaped clamping plate 32 is connected to the movable outer sleeve 3 by screws 33. When the movable outer sleeve 3 slips outwards, since the arc-shaped clamping plate 32 is blocked by the limiting outer ring 111, it cannot slip further, thus achieving the effect of connecting the movable outer sleeve 3.
[0027] Although the present utility model has been disclosed above with preferred embodiments, it is not intended to limit the present utility model. Any person skilled in the art can make many possible changes and modifications to the technical solution of the present utility model by using the above-disclosed technical content, or modify it into an equivalent embodiment with equivalent changes. Therefore, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall fall within the scope of protection of the technical solution of the present utility model.
