Description

Puncture drainage needle for dermatology

Technical Field

The utility model relates to the technical field of medical instruments, in particular to a puncture drainage needle for dermatology.

Background

Puncture, a commonly used medical operating term, is a diagnostic technique in which a puncture needle is inserted into a body cavity to extract secretions for testing, gas or contrast agents are injected into the body cavity to perform contrast examination, or medicines are injected into the body cavity. The purpose of puncture is to take blood for examination, blood transfusion, fluid infusion and to put in a catheter for angiography. Puncture drainage is often adopted in medical treatment, and on one hand, the puncture drainage can be used for analyzing body fluid of a patient and finding out a focus; on the other hand, the redundant effusion in the body of the patient can be extracted as a treatment scheme.

Although some existing puncture needles are provided with scale marks, the scale marks are rough, a doctor can only roughly judge the depth of the puncture needle after the puncture needle is punctured into the body of a patient, the entering depth cannot be accurately known, an experienced doctor can judge the position of the puncture needle according to hand feeling and experience, but the puncture needle is difficult for a novice doctor.

SUMMERY OF THE UTILITY MODEL

The utility model aims to provide a puncture drainage needle for dermatological department, which solves the problems in the background technology.

In order to achieve the purpose, the utility model provides the following technical scheme:

a dermatological puncture drainage needle comprising: pjncture needle and measuring device, the pjncture needle includes needle body and syringe needle, measuring device includes upper fixed ring, spring and lower fixed ring, upper fixed ring and lower fixed ring are the annular shape, and upper fixed ring passes through spring fixed connection lower fixed ring, simultaneously upper fixed ring suit is in on the syringe needle, with syringe needle fixed connection, and the needle body is followed pass in the middle of spring and the lower fixed ring, be equipped with pressure sensor and digital display on the lower fixed ring, lower fixed ring orientation upper fixed ring's one side is equipped with the guide bar, the guide bar is followed from upper fixed ring and is passed, be equipped with two clips on the guide bar.

As a further scheme of the utility model: the digital display can correspondingly display the puncture depth of the needle body according to the pressure measured by the pressure sensor.

As a further scheme of the utility model: the length of the needle body exceeds the overall length of the measuring device.

As a further scheme of the utility model: the upper fixing ring and the needle head are detachably mounted.

As a further scheme of the utility model: the guide rod is made of elastic rubber.

Compared with the prior art, the utility model has the beneficial effects that: when the puncture needle is used for puncture, the puncture depth of the puncture needle can be directly seen through the measuring device, so that a doctor can conveniently judge the position of the puncture needle, and the difficulty of puncture operation is reduced.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1 to 4, in an embodiment of the present invention, a puncture drainage needle for dermatology includes: puncture needle 1 and measuring device 2, puncture needle 1 includes syringe needle 11 and needle body 12, measuring device 2 includes upper fixing ring 21, spring 22 and lower fixing ring 23, upper fixing ring 21 and lower fixing ring 23 are the annular shape, and upper fixing ring 21 passes through spring 22 fixed connection lower fixing ring 23, simultaneously upper fixing ring 21 suit is in on syringe needle 11, with syringe needle 11 fixed connection, and needle body 12 follows pass in the middle of spring 22 and lower fixing ring 23, be equipped with pressure sensor and digital display 232 on the lower fixing ring 23, the length of needle body 12 excesses measuring device 2's whole length.

After the needle body 12 is pierced into a human body, the lower fixing ring 23 abuts against the position of the piercing hole, and the spring 22 is compressed along with the penetration of the needle body 12, at this time, the pressure sensor detects the pressure, and the digital display 232 can correspondingly display the piercing depth of the needle body 12 according to the pressure measured by the pressure sensor, so that a doctor can directly see the piercing depth of the piercing needle 1 from the digital display 232.

Go up solid fixed ring 21 with syringe needle 11 demountable installation, gu fixed ring 23 is equipped with guide bar 231 towards one side of last solid fixed ring 21 down, guide bar 231 follows from last solid fixed ring 21 and passes, be equipped with two clips 24 on the guide bar 231, guide bar 231 adopts the elastic rubber material, guide bar 231 can dismantle. With the puncture of the puncture needle 1, the spring 22 is compressed, the distance between the upper fixing ring 21 and the lower fixing ring 23 is shortened, so that the top of the guide rod 231 can extend out of the upper fixing ring 21, when the puncture needle 1 reaches a puncture point and stops to continue to go deep, the guide rods 231 on two sides of the upper fixing ring 21 can be clamped by the clamp 24, the lower fixing ring 23 is limited, and the position of the lower fixing ring 23 is fixed, so that the puncture needle 1 can be prevented from slipping outwards due to the restoring effect of the spring 22, and a doctor can be prevented from continuing to go deep into the puncture needle 1 due to an accident.

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 invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof.
