Description
Technical field
This utility model relates to a kind of sample harvester, belongs to technical field of medical instruments.
Background technology
For the diagnosis and the treatment of assisting disease, often need gather clinically various specimen, as: the collection of (1) endometrium, uterine cavity slough tissue/cell, uterus or vaginal secretion; (2) collection of stool sample, rectum slough tissue/cell, rectum juice; (3) collection of pus, inflammatory infiltrate, juice, slough tissue/cell in the abscess that communicates with body surface, the lacuna that moves under water, fistula road or the sinus tract, or the like.
But traditional collection of specimens technology is relatively backward, has many drawbacks: (1) traditional endometrium biopsy method is to expose cervix uteri earlier, sterilization, cervix dilating adopt the metal curet to be inserted at the bottom of the palace more then, are close to the palace wall and scrape from top to bottom and get, its complex operation, wound is bigger, is difficult for holding; (2) traditional stool collection method is, treat the patient voluntarily during defecation with common vessel (carton etc.) splendid attire, censorship, its process causes extraneous contamination easily; Collection to specimen such as rectum slough tissue/cell, rectum juices then needs to carry out under anus is peeped; (3) to the collection of pus, inflammatory infiltrate, juice, slough tissue/cell in abscess, fistula road or the sinus tract, traditional method normally extracts with syringe or scrapes with the metal curet at body surface and gets, and easily pollutes, and the tract table that exsomatizes is dark or when moving under water, and gathers difficulty.
The utility model content
The purpose of this utility model is to provide a kind of easy to operate, medical use sample harvester easy, that pollution rate is low of sampling.
For achieving the above object, the sample harvester that this utility model provides, comprise handle, push-pull bar, piston, outer tube and be located at the collection hole of outer tube front end, it is characterized in that described piston comprises that hemispheric head, the columned body that is connected with head and at least one be located at being used between body outer surface and the outer tube and increase the piston and the bubble-tight plate-like wing of outer tube.
Further, the described plate-like wing is two, is located at the middle front end and the middle rear end of the outer surface of cylindric body respectively.
The material of the described plate-like wing is a soft material.
Described columned body is to be provided with the hollow circular cylinder that is used to install the push-pull bar duct.
Described outer tube is the conduit with smooth hemispherical head, is provided with the scale indication body on the pipe shaft of conduit, is provided with the collection hole at the outer tube front end on the tube wall at hemispherical head 3～10mm place.
This utility model also can be improved to: be provided with in outer tube tail end and push-pull bar gap and be used to the spacing ridge that prevents that push-pull bar and piston from skidding off.
Further, described spacing ridge is the ridge shape structure to the tube chamber inner process that outer tube wall caves in and forms.
This utility model can also be used following technical measures: a kind of sample harvester, comprise handle, push-pull bar, piston, outer tube and be located at the collection hole of outer tube front end, it is characterized in that, described piston comprises the body of ellipsoid shape hollow head of being made by soft material and the hollow cylindrical that is connected with head, is provided with steam vent in the junction of head and body.
This utility model compared with prior art has following advantage: operation is convenient, draws materials accurately, be difficult for polluting, and wound is minimum.

The specific embodiment
Embodiment 1
As Figure 1-3, the sample harvester that this utility model provides, comprise handle 1, push-pull bar 2, piston 3, outer tube 4 and be located at the collection hole 5 of outer tube front end, the columned body 7 that piston 3 comprises hemispheric head 6, be connected with head and 2 are located at being used between body outer surface and the outer tube increases the piston and the bubble-tight plate-like wing 8 of outer tube, this plate-like wing 8 is located at the middle front end and the middle rear end of the outer surface of cylindric body 7 respectively, and the material of this plate-like wing 8 is soft material such as PVC material etc.
Wherein, outer tube 4 is elongated, a transparent conduit, and pipe shaft indicates scale, can enter the degree of depth of body cavity in order to indication; The sealing of outer tube front end is slick hemispherical, is beneficial to conduit and enters body cavity smoothly and can not cause any damage; On the tube wall of the about 3～10mm of hemispherical front end a circular hole 5 of gathering is arranged, its function is that specimen is sucked tube chamber through this; The tail end of outer tube 4 has a spacing ridge 9, is the ridge shape structure to the intracavity projection that tube wall caves in and forms, and its effect is to prevent that push-pull bar 2 and piston 3 from skidding off outer tube.
Push-pull bar 2 is solid, an elongated rod shaped structure, and its front end connects piston 3, and the rear end connects handle 1, and the three is one each other, when pulling handle 1, makes piston 3 interlocks, thereby forms negative pressure to suck specimen in the outer tube tube chamber.
Piston 3 is the special construction that an outward appearance slightly is the glans penis shape, comprises head 6, body 7 and the plate-like wing 8 three parts, and head 6 is hemisphere, and internal diameter is slightly less than outer tube diameter, and its shaped design is mainly to be convenient to piston 3 and to slide in tube chamber; Body 7 is a cylinder, is the part that head 6 is connected with push-pull bar 2, and there is a duct 10 in its central authorities, are used to install push-pull bar 2; The plate-like wing 8 is connected in body 7, and totally two, each one of front and back are poor disc shaped, are made by soft material, and its effect is the air-tightness that increases piston 3 and outer tube 4 tube chambers, and can be the conformal performance change according to the irregular slight change of lumen diameter, prevents gas leakage.
When above-mentioned sample harvester uses, the patient gets suitable position, sample harvester is slowly inserted target site such as uterus, rectum, body surface lacuna, deep abscess or the hole/fistula road etc. that moves under water, observe the scale on the sample harvester outer tube, to appropriate depth, pull out the harvester push-pull bar to form negative pressure, be about to this moment such as mucosal tissue/cell, slough tissue/cell, granulation tissue/cell, pus, transudate, juice etc. and suck in the harvester through gathering the hole.Take out harvester, advance push-pull bar to form malleation and to extrude specimen by gathering the hole; Bigger as piece of tissue, can cut off the part tube head to take out specimen.Specimen is positioned over (as biopsy bag, biopsy bottle, test tube, culture dish etc.) in special-purpose specimen bag or the vessel, send pathology, cytology or bacteriology checking.
Embodiment 2
Present embodiment as different from Example 1, as shown in Figure 4, piston 3 is made up of with the body 12 that is connected with head 11 head 11, head 11 combines together mutually with body 12, and head 11 is the spheroid of hollow; There are two steam vents 13 rear end of spheroid and body junction; Spheroid is made by soft material, because it is a hollow structure, adds the auxiliary of upper air-vent, can make it be conformal performance according to the irregular slight change of outer tube 4 lumen diameters and change, and prevents gas leakage.Body 13 is a cylinder, is the part that head 11 is connected with push-pull bar 2, and there is a duct 10 in its central authorities, are used to install push-pull bar 2.
This utility model is not limited in the above-mentioned specific embodiment scope, above-mentioned embodiment only is in order can be described in detail use of the present utility model, and the production method of equal function and the part that ins and outs also belong to this utility model content are arranged.In fact, those skilled in the art are according to the description of preamble, just can find different adjustment schemes according to needs separately, and these adjustment all should be in the scope of the claims by the appended claims herein.
