Abstract

The utility model discloses a male urethral sampling rod, which comprises a rod body. A elliptically spherical rod head is arranged at one end of the rod body, a handle is arranged at the other end, four sample reserving holes are circularly distributed in the middle of the rod head, the sampling reserving holes are blind holes, a detachable anesthesia rod is disposed at the front end of the rod head, four spindle-shaped grooves are arranged on the surface of the rod head along the elliptic long axial direction, the sample reserving holes are positioned at the middle positions of the grooves, two annular projections respectively between each two grooves are arranged on the surface of the rod head along the elliptic short axial direction, and the two annular projections are respectively arranged in the front and on the rear of the reserving holes. When in use, urethral membrane scraping and sample taking are carried out in a substantially painless state after local urethral anesthesia is carried out for a patient, pains to the patient are greatly reduced, proper secretion and mucous membrane samples can be obtained, accurate test to patients can be favored, and thereby the male urethral sampling rod is simple and speedy in operation, brings great convenience for medical staff, and further increases diagnosis efficiency and accuracy.

Description

The male urethra sampling rod

Technical field

This utility model relates to the instrument of drawing materials that uses in a kind of sexually transmitted disease (STD) outpatient service, specifically is the male urethra sampling rod that a kind of convenience is taken a sample from male urethra.

Background technology

In the sexually transmitted disease (STD) outpatient service, to have male urethra inflammation shape or and the patient of sign, need from its urethra, take out the urethral mucosa sample and detect pathogenic microorganisms such as whether having gonococcus, chlamydia trachomatis, ureaplasma urealyticum.Common sampling appliance is a medical aseptic defat cotton swab, is inserted in the male urethra, rotates to stop the several seconds behind this defat cotton swab again with its taking-up, and the mucosa sample can stick to absorbent cotton and sign, thereby chemically examines detection.The shortcoming of this defat cotton swab is: 1. the defat cotton swab need be inserted in the male urethra and in urethra and rotate, the defat cotton swab can bring more violent pain to the patient, bring huge misery to the patient, also reduced when the patient checks the compliance of sub-sampling again; 2. work as male urethra secretions more after a little while, only a small amount of secretions can be adsorbed in the cotton-wool of defat cotton swab, causes sampling seldom can't chemically examine detection; 3. work as male urethra secretions more for a long time, a large amount of secretions can wrap the defat cotton swab, thereby make the surface of defat cotton swab become smooth, are not easy to get the mucosa sample in the urethra, thereby cause chemically examining detection exactly.

The utility model content

The technical problems to be solved in the utility model provides a kind of when taking a sample from male urethra, can alleviate the patient suffering, shortens sample time and improve the male urethra sampling rod of sampling success rate.

For solving the problems of the technologies described above, the male urethra sampling rod that is provided, comprise barred body, one end of barred body is provided with caput, the other end is provided with handle, its construction features is: caput is for oval spherical, four holes that keep sample that have been periphery, the middle part of caput, the hole that keeps sample is a blind hole, the front end of caput is equipped with dismountable anesthesia rod, on the caput surface along being provided with four shuttle shape grooves on the long axis of ellipse direction, the described hole that keeps sample is positioned at the centre position of groove, and along being equipped with two annular projections in twos between the groove on the oval short-axis direction, two circular protrusions are separately positioned on the both sides, front and back in the hole that keeps sample on the caput surface.

After adopting said structure, when needs are taken a sample from male patient's urethra, can earlier the anesthesia rod be inserted in patient's urethra, after treating urethra anesthesia, extract this utility model and unload the anesthesia rod, caput is inserted in patient's urethra, holds handle push-and-pull barred body gently, needed mucosa sample can be stayed in keep sample hole or the shuttle shape groove.Elder generation carried out local anesthesia to patient's urethra when this utility model used, and to the sampling of urethra knifing, greatly reduced patient's misery, and can get an amount of secretions and mucosa sample under painless substantially state, helped the patient is chemically examined detection accurately.This utility model is easy and simple to handle, quick, for medical personnel bring great convenience, has also improved diagnosis efficiency and accuracy.

As improvement of the present utility model, the end face of described annular projection is little rough surface, is convenient to scraping of mucosa sample and gets.

The front end of nose is provided with blind hole, and the anesthesia rod comprises the anesthesia ball that the connecting rod that can be inserted into blind hole, the front end of connecting rod expand in the middle of being equipped with, two ends are gradually little.

Description of drawings

Below in conjunction with accompanying drawing this utility model is further described:

Fig. 1 is a structural representation of the present utility model;

The sketch map that Fig. 2 amplifies after analysing and observe for A-A among Fig. 1.

The specific embodiment

Male urethra sampling rod as depicted in figs. 1 and 2, comprise barred body 1, one end of barred body 1 is provided with caput 2, the other end is provided with the handle 7 of flat, caput 2, barred body 1 and handle 7 are all made by medical plastic, caput 2 is oval spherical, four shuttle shape grooves 3 have been periphery on caput 1 surface, each groove 3 is all along being provided with on the long axis of ellipse direction, the middle part of groove 3 is provided with the hole 4 that keeps sample, keep sample hole 4 is blind hole, on the short-axis direction of edge, caput 2 surface ellipse, also be evenly equipped with four annular projections 6, annular projection 6 is in twos between the groove 3, and the end face of annular projection 6 is little rough surface, is convenient to scrape get the mucosa sample, the front end of caput 2 is provided with blind hole, anesthesia rod 5 comprises the connecting rod 5-1 that is inserted into this blind hole, expands in the middle of the front end of connecting rod 5-1 is equipped with, the anesthesia ball 5-2 that two ends are gradually little anaesthetizes the lignocaine anesthesia liquid that can be stained with 1.5-3% concentration on the ball 5-2.

When using this utility model, now will anaesthetize ball 5-2 and adhere to an amount of lignocaine anesthesia liquid, then this anesthesia ball is slowly inserted 2-4cm in patient's urethra, stop and extract after 1-2 minute, extract this anesthesia rod 5 from the front end of caput 2, caput 2 is inserted in patient's the urethra, push-and-pull is rotated repeatedly, can scrape and get an amount of mucosa cell and secretions, so that medical personnel chemically examine detection.
