Abstract

The utility model discloses a urethra sampler comprising a sleeve, wherein a piston is slidably connected in the sleeve; a sampling head capable of stretching out of the front port of the sleeve is arranged on the piston; a handle is arranged at the rear part of the piston; the sampling head is composed of a conical section, an expansion section and a contraction section which are smoothly transited in sequence from front to back; a plurality of sampling holes are respectively annularly distributed in the outer surfaces of the conical section and the contraction section; the outer surface of the expansion section is a slightly-rough surface; a blind hole is formed at the front end of the sampling head; an anesthesia rod is inserted into the blind hole; and an anesthesia ball which is expanded in the middle and gradually decreased at two ends is arranged at the front end of the anesthesia rod. The urethra sampler disclosed by the utility model is simple, convenient and rapid in operation and has the advantages of greatly shortening the sampling time, increasing the sampling success rate, greatly reducing the pain of patients at the same time, bringing great convenience to medical workers and increasing the diagnosis efficiency and accuracy.

Description

A kind of urethral sampling device

Technical field

This utility model relates to a kind of urethral sampling device of taking a sample from male urethra of being used for.

Background technology

Urology Surgery or Andriatrics Dept. often will use the male urethra sampler to carry out the collection of urethral secretions BIAO and BEN when the diagnosing male reproductive tract infection.At present, the male urethra sampler that hospital adopts is a medical aseptic defat cotton swab, is inserted in the male urethra, stops the several seconds again with its taking-up after rotating this defat cotton swab, and the mucosa sample can stick to absorbent cotton and sign, thereby chemically examines detection.But, in the collection of specimens process, have following problem and shortcoming: when 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 few and can't chemically examine detection; When 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 problem that this utility model will solve provides a kind of when from male urethra, taking a sample, and can shorten sample time and the urethral sampling device that improves the sampling success rate.

For solving the problems of the technologies described above; The urethral sampling device that is provided comprises sleeve; Slidely connect piston in the sleeve, the sampling head that can stretch out the barrel forward end mouth is housed on the piston, handle is equipped with at the rear portion of piston; Its construction features is: sampling head is by the conical section of rounding off, the section of expanding and tighten section and forms successively after going to certainly, and a plurality of samplings hole has been periphery respectively on conical section and the outer surface that tightens section.

The outer surface of the said section of expanding is little rough surface.

The front end of said sampling head is provided with blind hole, is fitted with the anesthesia rod on the blind hole, the anesthesia ball that expand in the middle of the front end of anesthesia rod is equipped with, two ends is gradually little.

After adopting said structure, because sampling head is provided with conical section, the section of expanding and deflation section after going to, on the conical section and aftermost deflation section of sampling hole forefront; After sampling head is stretched into urethra, in the process of inserting again and extracting, all have secretions and mucosa and get into the sampling hole; No longer need rotate this sampling head, thereby shorten sample time greatly, improve the sampling success rate; Also greatly reduce simultaneously patient's misery, help the patient is chemically examined detection accurately.And be provided with structures such as sleeve, handle, help the insertion depth that the operator controls sampling head.This utility model is easy and simple to handle, quick, for medical personnel bring great convenience, has also improved diagnosis efficiency and accuracy.

After adopting the version of above-mentioned plug-in mounting anesthesia rod; Need to use anaesthetic apparatus no longer separately, through picking the lignocaine anesthesia liquid on the anesthesia ball urethra is anaesthetized, after the anesthesia; Take off the anesthesia rod; The blind hole of sampling head front end also can be used as the sampling hole, inserts in the process of urethra at sampling head, also has part mucus or mucosa and gets in this blind hole.

Description of drawings

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

Fig. 1 is the structural representation of this utility model;

Fig. 2 is the cutaway view of sampling head.

The specific embodiment

Urethral sampling device as shown in Figure 1 comprises sleeve 1, slidely connects piston 4 in the sleeve 1; Be connected with thief rod 7 that can stretch out sleeve 1 front port and the sampling head 2 that is contained in thief rod 7 front ends on the piston 4; Handle 3 is equipped with at the rear portion of piston, and the front end of sleeve 1 can be equipped with buckles medicated cap 8, and telescopic outer surface is provided with scale; The signable propelling length that goes out handle 3, thereby the extension elongation (promptly inserting the degree of depth of urethra) of control sampling head 2.

As depicted in figs. 1 and 2; Sampling head 2 is by the conical section 21 of rounding off, the section of expanding 22 and deflation section 23 are formed successively after going to certainly; The a plurality of samplings hole 24 that has been periphery respectively on conical section 22 and the outer surface that tightens section 23, the outer surface of the section of expanding 22 is little rough surface, is convenient to scrape get the mucosa sample.The front end of sampling head 2 is provided with blind hole 25, is fitted with anesthesia rod 5 on the blind hole 25, the anesthesia ball 6 that expand in the middle of the front end of anesthesia rod 5 is equipped with, two ends is gradually little.

When using this utility model; To anaesthetize ball 6 at present and adhere to an amount of lignocaine anesthesia liquid, then this anesthesia ball slowly inserted 2-4cm in patient's urethra, and stop and extract after 1-2 minute; Extract this anesthesia rod 5 from the front end of sampling head 2; Sampling head 2 is inserted in patient's the urethra, just can scrapes after extracting and get an amount of mucosa cell and secretions, so that medical personnel chemically examine detection.
