In order to solve the above technical problems, the utility model is realized by adopting the following technical solutions:

An improved chest cavity drainage joint, comprising a joint body, a first joint connected to a drainage tube is provided at one end of the joint body, and a second joint connected to a chest tube is provided at the other end of the joint body, characterized in that , a third joint is provided in the middle of the joint body, a first interface for injecting medicine into the patient's chest is provided on one side of the third joint, and a first interface for injecting medicine into the patient's chest is provided on the other side of the third joint. For the second interface for sampling, a switch capable of switching between the first interface and the second interface is further provided on the third joint.

In a preferred embodiment of the present invention, a first heparin cap and a second heparin cap are respectively covered on the first interface and the second interface.

In a preferred embodiment of the present utility model, the second joint is a tapered structure whose outer diameter gradually decreases from one end close to the joint body to one end away from the joint body, and the outer peripheral surface of the tapered structure is arranged at intervals in the axial direction There are several concave limit steps.

Compared with the prior art, the utility model is provided with a third joint in the middle of the joint body, and on one side of the third joint is provided a first interface for injecting medicine into the patient's thorax, and on the other side of the third joint There is a second interface for sampling, and a switch that can switch between the first interface and the second interface is provided on the third joint. With this structure, when medical staff need to inject drugs to patients or use them, Only need to pass through the first port or the second port to perform the action of injecting medicine more conveniently, without needing to pierce the chest tube with a needle, avoiding the chest tube from being polluted by foreign objects, which is beneficial to the early recovery of the patient.

Description of drawings

In order to more clearly illustrate the technical solutions in the embodiments of the present invention or the prior art, the following will briefly introduce the accompanying drawings that need to be used in the description of the embodiments or the prior art. Obviously, the accompanying drawings in the following description These are only some embodiments of the utility model, and those skilled in the art can also obtain other drawings based on these drawings without creative work.

Fig. 1 is the structural representation of the utility model.

Fig. 2 is a structural schematic diagram of the utility model after it is connected with a drainage tube and a chest tube.

Detailed ways

In order to make the technical means, creative features, goals and effects achieved by the utility model easy to understand, the utility model will be further elaborated below in conjunction with specific illustrations.

Referring to FIG. 1 and FIG. 2 , an improved chest drainage connector shown in the figure includes a hollow connector body 100 .

One end of the connector body 100 is provided with a first connector 110 connected to the drainage tube 400, and the drainage tube 400 is connected to the drainage bottle 200, and the other end of the connector body 100 is provided with a second connector 120 connected to the chest tube 500, and the chest tube 500 is connected to the second connector 120. The tube 500 communicates with the chest cavity 300 of the patient, and adopting this structure facilitates the discharge of the effusion in the patient's chest cavity, which is beneficial to the early recovery of the patient.

The second joint 120 is a tapered structure in which the outer diameter gradually decreases from one end close to the joint body 100 to one end away from the joint body 100. The outer peripheral surface of the tapered structure is provided with a number of concave limit steps 121 at intervals along the axial direction. Such a structure can effectively prevent the chest tube 500 from falling off from the second connector 120 , so that the second connector 120 and the chest tube 500 are firmly connected together, and the stability of the connection between the chest tube 500 and the connector is improved.

A third joint 130 is provided in the middle of the joint body 100, a first interface 131 for injecting medicine into the patient's chest cavity 300 is provided on one side of the third joint 130, and a first port 131 for injecting medicine into the patient's chest cavity is provided on the other side of the third joint 130. The second interface 132 for sampling.

When the medical personnel need to inject medicine to the patient or use it, they only need to use the first interface 131 or the second interface 132 to perform the action of injecting medicine more conveniently, without needing to puncture the chest tube 500 with a needle, avoiding the chest tube 500 to the outside. pollution, which is conducive to the early recovery of patients.

The third joint 130 is also provided with a switch 133 capable of switching between the first interface 131 and the second interface 132. When the medical personnel need to inject medicine to the patient, they switch to the first interface 131 through the switch 133, so that The first interface 131 is connected with the third joint 130, and finally the medical personnel can inject medicine to the patient's chest cavity 300 more conveniently through the first interface 131; The interface 132 connects the second interface 132 with the third connector 130 , and finally the medical staff can conveniently sample the patient through the second interface 132 .

The first interface 131 and the second interface 132 are respectively covered with a first heparin cap 131a and a second heparin cap 132a, and the first heparin cap 131a and the second heparin cap 132a can effectively prevent the first interface 131 from connecting with the second interface. 132 is contaminated by foreign objects, which is conducive to the early recovery of patients.

In summary, the utility model is provided with a third joint in the middle of the joint body, on one side of the third joint is provided with a first interface for injecting medicine into the chest cavity of the patient, and on the other side of the third joint is provided with a The second interface for sampling is also equipped with a switch on the third joint that can switch between the first interface and the second interface. With this structure, when the medical staff needs to inject drugs to the patient or use them, they only need to pass The first interface or the second interface can be used for injecting drugs more conveniently, without needing to puncture the chest tube with a needle, avoiding the contamination of the chest tube by foreign objects, and facilitating the early recovery of patients.
