Abstract
The utility model relates to a closed suction catheter connector assembly with a medicine injection unit and a cleaning unit, which comprises a connector body. One end inside the connector body is connected with a rotary connector core, the other end of the connector body is communicated with a valve seat, a slide valve switch is arranged on the valve seat, the upper portion of the connector body is provided with the medicine injection unit communicated with the connector body, and the lower portion of the connector body is communicated with a rotary connector. The closed suction catheter connector assembly is characterized in that the connector body is further provided with the cleaning unit communicated with the connector body. Each of the medicine injection unit and the cleaning unit comprises an elbow, a catheter body and a catheter seat, wherein the insides of the catheter seat are check valve structures. The closed suction catheter connector assembly has the advantages that during clinical usage of the closed suction catheter connector assembly, certain pressure is exerted on a valve spool through a round hole on a valve body, accordingly, a spring is compressed, the valve spool slides inwards, and liquid medicine or cleaning liquid can be injected. When the liquid is injected, the valve spool returns to the original position due to the action of the spring, accordingly, the liquid is prevented from overflowing in a reversed direction, and the closed suction catheter connector assembly is fast and safe in clinical usage and simple in operation.
Description
Technical field
This utility model belongs to clinical medicine and uses utensil, particularly relates to a kind of closed endotracheal suction interface tube assembly with injection and cleaning unit.
Background technology
At present, in respiratory system disease, general anesthesia operation treatment and the emergency rescue, often carry out tracheal intubation or tracheostomy tube, and utilize the closed endotracheal suction pipe to absorb secretions in the respiratory tract to the patient.The patient of this type, because the relation of primary disease, state of an illness situation and sputum aspirator tube itself, air flue is in high reactive state, needs medication.The closed endotracheal suction pipe practices artificial respiration when clinical use usually simultaneously, owing in the respirator joint pressure is arranged, the situation of overflow of drug fluid appears in conventional medicine injecting unit sometimes.In addition, when carrying out the sputum aspirator tube cleaning, the excessive phenomenon of cleanout fluid also can appear in cleaning unit sometimes, can bring many troubles and inconvenience to medical personnel like this, and then has increased medical personnel's work load.
Summary of the invention
This utility model is for solving the closed endotracheal suction interface tube assembly with injection and cleaning unit that the technical problem that exists in the known technology provides a kind of reasonable in design, is convenient to medical personnel's operation.
The technical scheme that this utility model is taked for the technical problem that exists in the solution known technology is:
Closed endotracheal suction interface tube assembly with injection and cleaning unit; Comprise an interface body, an end is connected with the rotatable interface core in this interface body, and the other end is communicated with valve block; Slide valve switch is housed on the valve block; Said interface body top also is provided with the medicine injecting unit with its perforation, and the bottom is communicated with swivel joint, it is characterized in that: also be provided with the cleaning unit with its perforation on the said interface body; Said medicine injecting unit and cleaning unit comprise elbow, body and base, and said base inside is one-way valve structures.
This utility model can also adopt following technical scheme:
Said check valve is made up of spool, spring, valve body and valve body connector, and spring places the valve body bottom, and spool places on the spring, and valve body connector and body are affixed.
Said spool adopts polypropylene material to process.
Said valve body adopts the flexible PVC material to process, and said valve body connector is processed for the K resin.
Advantage and the good effect that the utlity model has are: because this utility model adopts technique scheme; When clinical use; Bestow certain pressure through circular hole on the valve body to spool, make spring compression and spool inwardly slide, realize the injection of medicinal liquid or cleanout fluid.After liquid injected completion, spool was because the effect of spring sets back, and it is excessive in the other direction that liquid that can not is occurred, and this makes, and the closed endotracheal suction pipe is more convenient when clinical use, safety, operates simpler.

Fig. 1 is the structural representation of this utility model;
Fig. 2 is the structural representation of this utility model cleaning unit.
Among the figure: 1, interface core; 2, interface body; 3, valve block; 4 slide valve switches; 5, swivel joint; 6, medicine injecting unit; 7, cleaning unit; 8, elbow; 9, body; 10, check valve; 10-1, spool; 10-2, valve body connector; 10-3, spring; 10-4, valve body.
The specific embodiment
For further understanding summary of the invention, characteristics and the effect of this utility model, the following examples of giving an example now, and conjunction with figs. specifies as follows:
See also Fig. 1 and Fig. 2; Have the closed endotracheal suction interface tube assembly of injection and cleaning unit, comprise an interface body 2, an end is connected with rotatable interface core 1 in this interface body; The other end is communicated with valve block 3; Slide valve switch 4 is housed on the valve block 3, and said interface body top also is provided with the medicine injecting unit 6 with its perforation, and the bottom is communicated with swivel joint 5.Said interface body top also is provided with the cleaning unit 7 with its perforation, and said medicine injecting unit and cleaning unit include elbow 8, body 9 and base and constitute, and said base inside is check valve 10.In the present embodiment, said check valve is made up of spool 10-1, spring 10-3, valve body 10-4 and valve body connector 10-2, and said spring places the valve body bottom, and spool places on the spring, and valve body connector and body are affixed.Said spool adopts polypropylene material to process, and said valve body adopts the flexible PVC material to process, and said valve body connector is processed for the K resin.
During operation, bestow certain pressure to spool, make spring compression and spool inwardly slide, realize the injection of liquid such as medicinal liquid or cleanout fluid simultaneously through circular hole on the valve body.
