Background

The pus sampling needle is the medical instrument who is used for absorbing the pus, and current pus sampling needle simple structure, the function singleness when using, when the pjncture needle stretched into the pustule intracavity and extracts the pus, during tissue or blood permeated the pus sample easily, thoughtlessly had a large amount of impurities in the pus sample after the collection, and then influenced the quality of sample and follow-up detection to the pus, and the practicality is poor, for this reason, we propose a medical pus sampling needle.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a medical pus sampling needle to propose current pus sampling needle and mix the problem that has impurity easily when gathering the pus in solving above-mentioned background art.

In order to achieve the above object, the utility model provides a following technical scheme:

the utility model provides a medical pus sampling needle, includes a fixed section of thick bamboo, vertical grafting has the pjncture needle that runs through the setting in the fixed section of thick bamboo, the pjncture needle is hollow form, and still is equipped with the sampling needle in the pjncture needle, the bottom of sampling needle is the cecum, the feed liquor hole has been seted up to the bottom of sampling needle and the one side that is close to the cecum, the top of fixed section of thick bamboo is equipped with can dismantle the nut head, can dismantle nut head in-connection has injection needle tubing, and injection needle tubing intercommunication sampling needle, the spring is installed to the outer wall that just is located the pjncture needle in the fixed section of thick bamboo.

Further: and a safety lock is installed at the top end of the fixed cylinder.

Further: the puncture needle is consistent with the length of the sampling needle, the puncture needle is consistent with the length of the sampling needle when not used and is in a sleeve shape, and the sampling needle extends out and is slightly longer than the puncture needle when in use.

And further: the bottom ends of the puncture needle and the sampling needle are inclined.

Further: handles are mounted on the outer walls of the two sides of the fixed cylinder, and anti-skidding sleeves are mounted at the holding ends of the handles.

Compared with the prior art, the beneficial effects of the utility model are that:

the telescopic puncture sampling needle of the utility model can smoothly reach a target area, has simple structure and convenient operation, and can be inserted into a pus cavity to directly suck pus through the action of the spring, thereby avoiding the influence on the quality of a sample due to the infiltration of blood into the sample in the puncture process and improving the accuracy of the subsequent pus detection; the feed liquor hole that the sampling needle bottom was seted up is changeed and is carried out the pus collection, improves sampling efficiency, and the practicality is good.

In the figure: 1. a fixed cylinder; 2. a handle; 3. the nut head can be detached; 4. a safety lock; 5. puncturing needles; 6. a sampling needle; 7. a liquid inlet hole; 8. a blind end; 9. an injection needle tube; 10. a spring.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Example 1:

referring to fig. 1-3, the present invention provides a technical solution: a medical pus sampling needle comprises a fixed cylinder 1, a puncture needle 5 which is vertically inserted and arranged in the fixed cylinder 1, the puncture needle 5 is hollow, a sampling needle 6 is also arranged in the puncture needle 5, the bottom end of the sampling needle 6 is a blind end 8, one side of the bottom end of the sampling needle 6, which is close to the blind end 8, is provided with a liquid inlet hole 7, the top end of the fixed cylinder 1 is provided with a detachable nut head 3, an injection needle tube 9 is connected in the detachable nut head 3, the injection needle tube 9 is communicated with the sampling needle 6, a spring 10 is arranged in the fixed cylinder 1 and is positioned on the outer wall of the puncture needle 5, when in use, the sampling needle 6 is embedded in the puncture needle 5, the sampling needle 6 and the puncture needle 5 are inserted into the fixed cylinder 1, medical personnel hold the assembled fixed cylinder 1 (the sampling needle 6 and the puncture needle 5) by hands, the detachable nut head 3 is detached, the injection needle tube 9 is inserted in the sampling needle 6, the sampling needle 6 in the puncture needle 5 is inserted in a pus cavity to directly suck pus through the effect of the spring 10, the liquid inlet hole 7 at the bottom end of the sampling needle 6 can suck pus from the lateral direction, and the influence on the quality of the specimen due to the blood infiltration in the puncture process is avoided.
