Description

Tracheotomy catheter

Technical Field

The utility model relates to the technical field of medical appliances, in particular to a tracheotomy catheter.

Background

Tracheotomy is a procedure in which, when a patient experiences dyspnea, the tracheotomy is performed and an artificial respiratory tract is established through a catheter; in this procedure, it is necessary to use a tracheostomy tube, i.e., one end of the tube is inserted into the trachea after tracheotomy and the other end is connected to a ventilator or the like to assist breathing.

In the related art, some tracheotomy catheters are also provided with sputum suction pipes, one end of each sputum suction pipe is led into the catheter, the other end of each sputum suction pipe is led out of the catheter and connected with the sputum suction component such as the air sac, and when more sputum exists in the trachea, the sputum suction pipe can suck out the sputum; such as a tracheostomy tube structure disclosed in patent document CN 215231282U.

For the catheter with the sputum suction pipe, the sputum suction component and the sputum suction pipe are generally detachably connected, specifically, one end of the sputum suction pipe, which is led out of the catheter, is provided with a joint, when sputum suction is needed, the joint is connected with the sputum suction component, and negative pressure sputum suction is formed by operating the sputum suction component; and when the sputum sucking part is not needed, the sputum sucking part is detached from the connector.

When the catheter is not required to suck phlegm, the joint is exposed, so that the joint is easy to pollute, and the hose at the joint can be scattered outside and easily extruded and pulled, so that the catheter is still to be improved.

Detailed Description

The technical solutions of the embodiments of the present utility model will be explained and illustrated below with reference to the drawings of the embodiments of the present utility model, but the following embodiments are only preferred embodiments of the present utility model, and not all embodiments. Based on the examples in the implementation manner, other examples obtained by a person skilled in the art without making creative efforts fall within the protection scope of the present utility model.

In the following description, directional or positional relationships such as the terms "inner", "outer", "upper", "lower", "left", "right", etc., are presented for convenience in describing the embodiments and simplifying the description, and do not indicate or imply that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore should not be construed as limiting the utility model.

Referring to fig. 1-3, the embodiment provides a tracheotomy catheter, which comprises a catheter body 1 and a sputum aspirator tube 2 penetrating the catheter body 1, wherein one end of the sputum aspirator tube 2 is led out of the catheter body 1 and is connected with a connector 21, it should be noted that at least the part of the sputum aspirator tube 2 led out of the catheter body 1 is in a hose structure so as to ensure that the catheter can be bent, and the position of the sputum aspirator tube 2 penetrating the catheter body 1 is fixedly connected with the catheter body 1.

As shown in fig. 1, the outer portion of the catheter body 1 is fixedly connected with a receiving member 3, a receiving space 31 is provided inside the receiving member 3, and one end of the receiving space 31 is opened to form an open end, in this embodiment, the receiving member 3 is preferably in a circular tube structure, and one end of the receiving member, which is far away from the catheter body 1, is an open end.

The tracheostomy tube further comprises an end cover 5 and a plug 4, the plug 4 can be attached to the joint 21 to plug the joint 21, and the plug 4 has the function that the joint 21 is plugged through the plug 4 when the joint 21 is idle so as to prevent oxygen from flowing out of the joint 21 when the catheter body 1 is in oxygen supply. And when the connector 21 is needed to be connected with the sputum aspirator, the plug 4 can be taken out. Wherein the sputum sucking component can be an air bag, a syringe or a sputum sucking pump, etc.

In order to enable the plug 4 to have better tightness when the joint 21 is plugged, in this embodiment, the plug 4 has a columnar structure and has elasticity, and specifically, the plug 4 made of rubber material may be adopted; as shown in fig. 2, the plug 4 is plugged into the joint 21 and is in interference fit with the joint 21 to realize plugging of the joint 21.

The end cover 5 is detachably covered at the open end of the accommodating space 31 to block the open end.

By arranging the containing member 3 with the containing space 31 on the catheter body 1 and arranging the plug 4 and the end cover 5 at the same time, when the joint 21 of the sputum aspirator tube 2 does not need to be connected with a sputum aspirator component, the plug 4 can plug the joint 21, then the part of the sputum aspirator tube 2 connected with the joint 21 through the joint is plugged into the containing space 31, and finally the end cover 5 is covered; in this way, the joint 21 is enclosed in the accommodating space 31, so that the joint is not easy to pollute, and the joint 21 and the sputum aspirator tube 2 are not scattered and extruded and pulled, so that the joint 21 and the sputum aspirator tube 2 are protected.

In this embodiment, the plug 4 is preferably disposed on the inner side of the end cap 5 and is fixed relative to the end cap 5, which means that the connector 21 can move together with the end cap 5 when the end cap 5 is removed, so that the connector 21 can be pulled out from the accommodating space 31, and thus, the connector 21 can be pulled out without extending a hand into the accommodating space 31, which facilitates the removal of the connector 21.

In order to ensure the tightness between the end cap 5 and the accommodating space 31, it is preferable that the end cap 5 is hermetically connected to the open end of the accommodating space 31 in the closed state. Specific:

as shown in fig. 2 and fig. 3, the inner side surface of the end cover 5 is provided with a protrusion 51, and the outer periphery of the protrusion 51 is sleeved with a sealing ring 6 with a cross section adapted to the cross section of the open end of the accommodating space 31, for example, in this embodiment, the open end of the accommodating space 31 is circular, so in this embodiment, the protrusion 51 is in a disc structure, and the sealing ring 6 is in a ring structure, where the sealing ring 6 may be made of rubber.

In the closed state of the end cover 5, the sealing ring 6 is plugged into the open end of the accommodating space 31 along with the convex part 51, and the sealing ring 6 is in interference fit with the inner peripheral wall of the open end of the accommodating space 31.

In order to prevent the sealing ring 6 from being separated from the end cover 5, the inner end of the protruding portion 51 is fixedly provided with a skirt 52 extending radially outwards, the sealing ring 6 is arranged between the skirt 52 and the end cover 5, and at this time, the end cover 5 and the skirt 52 are equivalent to two limiting points in the axial direction, so that the sealing ring 6 is kept positioned relative to the end cover 5 in the axial direction, and the sealing ring 6 is prevented from being separated from the end cover 5.

It will be evident to those skilled in the art that the utility model is not limited to the details of the foregoing illustrative embodiments, and that the present utility model may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. The present embodiments are, therefore, to be considered in all respects as illustrative and not restrictive, the scope of the utility model being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
