Abstract
The invention provides a needleless sampling connector and belongs to the technical field of medical instruments. The needleless sampling connector comprises a connector body, one end of the connector body forms a telescopic matching connector, the other end of the connector body forms an insertion hole, and the insertion hole is communicated with the telescopic matching connector. The needleless sampling connector is characterized in that a sampling plug accommodating cavity is arranged on the middle wall of the connector body and communicated with the insertion hole, a sampling plug is embedded into the sampling plug accommodating cavity, and a self-closing gap is reserved on the sampling plug. The needleless sampling connector has the advantages that repeated sampling can be achieved, and safety can be realized as sampling is carried out without a needle.
Description
Technical field
The invention belongs to the medical devices technical field, be specifically related to a kind of needleless sampling joint
Background technology
As the industry's knowledge of the reason, usually dispose connection wye on the negative-pressure drainage tube such as catheter, breast/abdominal cavity depression drainage device, this connection wye also claims the three way cock, and two end points in the threeway are used for the connection for pipe, and the 3rd end points is for the injection sampling.Adopt the shortcoming of entry needle sampling to be: in case sampling finishes, can cause sepage, thereby connection wye can only be suitable for unique once sampling, namely can not repeated sampling, and in urethral catheterization or negative pressure drainage process, often have the repeatedly situation of sampling, in order to dynamically grasp patient's pathological state, for taking necessary treatment measure, the medical worker provides accurately information, for example adjustment or change are convenient to as early as possible rehabilitation of patient to patient's medication.In addition, adopt the entry needle sampling to have the anxiety that injures medical worker's limbs
Summary of the invention
Task of the present invention is to provide a kind of both can satisfy the repeated sampling requirement, can avoid again undermining medical worker's limbs and the fast needleless sampling joint of sample rate.
Task of the present invention is finished like this, a kind of needleless sampling joint, comprise a joint body, one end of this joint body consists of a casing coupling formula connector, and the other end consists of a spliced eye, and spliced eye communicates with casing coupling formula connector, be characterised in that: the wall body at the middle part of joint body offers a sampling plug container cavity, this sampling plug container cavity communicates with described spliced eye, and is equipped with a sampling plug in this sampling plug container cavity, and consisting of beyond the Great Wall in this sampling has a self-closing slot.
The material of sampling plug of the present invention is silicone rubber.
The width of self-closing slot of the present invention is 0.5-2 ㎜.
Technical scheme provided by the invention is in the time will sampling, as long as the liquid inlet head (injecting needle base) of syringe is inserted in the sampling plug, the self-closing slot is injected crowded the opening of liquid inlet head of device under external force, the extraction liquid in the joint body of flowing through, when the liquid inlet head of syringe is recessed the sampling plug, then the self-closing slot is closed, thereby can realize repeated sampling, and can embody safety owing to need not to use the entry needle sampling.
Description of drawings
Fig. 1 is the embodiments of the invention structure chart.
The specific embodiment
Ask for an interview Fig. 1, provided a joint body 1, joint body 1 is by plastic production, an end of joint body 1 be the shown position state towards under an end consist of a casing coupling formula connector 11 arranged, casing coupling formula connector 11 is used for connecting with flexible pipe for medical purpose, the other end of joint body 1 is that the shown position state has a spliced eye 12 towards upper end formation, and this spliced eye 12 also can be described as insertion hole, is used for inserting spliced eye 12 for flexible pipe for medical purpose and undoubtedly communicates with casing coupling formula connector 11.
Main points as technical scheme provided by the invention: the wall body at the middle part of joint body 1 offers the sampling plug container cavity 13 that a shape is not subjected to the shape shown restriction, this sampling plug container cavity 13 communicates with aforementioned spliced eye 12, and in this sampling plug container cavity 13, with the compensation way embedding one sampling plug 131 is arranged, the material of this sampling plug 131 is to have excellent elastic silicone rubber (also can be described as silicone rubber for sealing), and be designed with a self-closing slot 1311 at sampling plug 131, the width of self-closing slot 1311 is preferably 0.5-2 ㎜, be 0.8-1.8 ㎜ preferably, be 1-1.5 ㎜ better, be preferably 1.2 ㎜, present embodiment is 1.2 ㎜.In addition, the shape of sampling plug container cavity 13 is preferably ellipse or circle, the relation that the shape maintenance of the shape of the plug 131 of sampling and sampling plug container cavity 13 is followed in sb's footsteps, and namely both should be consistent.
In the time will sampling, the liquid inlet head of syringe is aimed at sampling plug 131 and slightly with the application of force, make aforesaid self-closing slot 1311 expansions by the medical worker, pull out the plunger of syringe, under suction function, the sample solution in the joint body 1 of flowing through enters in the syringe.When recessing syringe, that is, the liquid inlet head of syringe was recessed the sampling plug at 131 o'clock, aforesaid self-closing slot 1311 is just closed.Here the liquid inlet head of saying is essentially the needle stand that entry needle is set.When again sampling, with the surperficial wiping of aseptic cotton to sampling plug 131, implement again sampling first
