Abstract

The utility model relates to a negative pressure type multi-purpose tube for taking a sample of excrement, which is composed of a saccule type suction tube 1 and a casing tube 2 sheathed outside the saccule type suction tube 1. The negative pressure type multi-purpose tube is sealed by a packaging bag and is packed into a complete set. The saccule type suction tube 1 is composed of a saccule and a suction tube and is manufactured and molded by transparent nontoxic plastic. The insertion end of the suction tube is thin, and the insertion end head is made into a smooth hemispherical face. The upper side face of the hemispherical face is provided with an opening of which the section is in a half-moon shape, and the opening is communicated with a chamber of the suction tube. The outer casing tube 2 is made into a transparent plastic casing tube with scales, and the bottom is smooth and semicircular. The saccule is held and squeezed by hand to make the inner parts of the saccule and the suction tube generate negative pressure to attract the sample of excrement into the suction tube. After the excrement is obtained, the suction tube is inserted into the outer casing tube 2 and is plugged tightly, and the simple has no seepage. The utility model is convenient to collect, transport, detect and preserve samples of wean excrement.

Description

Negative pressure type tube for taking sample of manure

This utility model relates to a kind of medical excrement sample collection equipment.

Routine clinical chemical examination, be greatly one of assay specimen, adopt just, when needing in time to obtain excrement sample because baby children patient can not cooperate, difficulty usually takes place, and the specimen of leaving and taking is with splendid attires such as cartons, and is easily dry or pollute, and influences testing result, particularly influence the accuracy of bacteria cultivation results, when using glass feces collection pipe,, there is damage children's's danger because glass is easily broken, and the success rate of collect specimen is low, especially defecate after a little while in rectal cavity, Chang Buneng collects specimen, to the excrement sample that collects, censorship is also inconvenient, easily dry or contaminated, and scrub sterilization inconvenience, so use less clinically.

The purpose of this utility model is, the negative-pressure type that provide the collection of a kind of children's's of being convenient to excrement sample, transports, detects and preserve overall process is used the excrement sample collection tube more.

Negative-pressure type is used the excrement sample collection tube more, form by the trocar sheath 2 that sacculus formula suction pipe 1 is outer with being sleeved on sacculus formula suction pipe, seal packaging kit with packaging bag, sacculus formula suction pipe 1, constitute by sacculus and suction pipe, shape with transparent non-toxic plastics, the insertion end of suction pipe is thinner, caliber increases to cervical region gradually, the insertion termination of suction pipe is slick and sly hemisphere face, can insert anus with no damage, at the hemispherical upper side of slyness the cross section is set and is semi-moon shaped opening, the semilune opening communicates with suction cavity, this opening is opened in the hemisphere face upper side, excrement sample is trapped in the hemisphere face termination, and enters in the suction cavity, hold the sacculus extruding, can make in the capsule and generation negative pressure in the suction pipe; Attract excrement sample to enter suction pipe,, in case of necessity, inject rectum, push sacculus repeatedly, can gather excrement sample by inhaling normal saline to particular patients '.Because the tube segment front end is thinner, adopt when inserting trocar sheath after an action of the bowels, the overcoat mouth of pipe is not contaminated, and after the suction pipe cervical region more slightly puts trocar sheath, but the overcoat mouth of pipe and suction pipe cervical region jam-pack, liquid is non-leakage, whole negative pressure is used the excrement sample collection tube more, the appearance cleaning is unscrewed trocar sheath, takes out suction pipe, can do routine examination, also can push sacculus, impel specimen to flow out or enter in the trocar sheath, add appropriate amount of fluid, do relevant the inspection after the centrifugal treating, valuable special specimen can put trocar sheath, and directly trocar sheath is deposited in cold, make graduated lucite pipe, the bottom slyness is hemispherical.

This utility model is compared the advantage that is had with prior art, and safety is good, can overcome the shortcoming of the frangible easy damaged of glass feces collection pipe, and cross-contamination does not take place in disposable use, and can prevent that stool from polluting surrounding; Excrement sample be can guarantee to gather, and the collection children's's excrement sample and the examination in hospital that is easy to carry in the family made things convenient for; Can guarantee specimen quality, prevent the specimen drying, contaminated, especially preferably to need work stool antibacterial culturing or viral isolating specimen; Can be directly frozen to special excrement sample, or check after remote the transmission, the epidemiological investigation of diseases such as diarrhoea also be applicable to.

Accompanying drawing is that negative-pressure type is used excrement sample collection tube sketch map more.

The following example is described in conjunction with the accompanying drawings:

A kind of children's uses the excrement sample collection tube with negative-pressure type more, form by sacculus formula suction pipe 1 and the trocar sheath 2 that is sleeved on outside the sacculus formula suction pipe 1, sacculus formula suction pipe 1, constitute by sacculus and suction pipe, the insertion end of suction pipe is thinner, caliber increases to cervical region gradually, and slick and sly hemisphere face is made in the insertion termination of suction pipe, in the hemispherical upper side setting of slyness, the cross section is the semilune opening, aperture φ=the 8mm of semilune opening, the slick and sly no burr in the edge of semilune opening inserts the termination and makes slick and sly hemisphere face SR=4mm, external diameter φ=the 15mm of suction pipe cervical region, the long 80mm of suction pipe, suction pipe add sacculus length overall 120mm, sacculus formula suction pipe 1, use the transparent non-toxic plastics blow molding, requirement has the toughness and the flexibility of appropriateness, pipe thickness δ=1.5mm, trocar sheath 2, make graduated transparent plastic casing, the bottom slyness is hemispherical SR=7.5mm, trocar sheath bore φ=15mm, and length is 90mm.During assembling, be coated with the small amount of liquid petrolatum on the slick and sly sphere in the termination of sacculus formula suction pipe 1, the outer suit trocar sheath 2 of suction pipe is with ray sterilizing behind the packaging bag sealing packaging kit or use oxirane disinfection.
