Description
Technical field
The present invention relates to a kind of disposable humoral indwelling device, more specifically to a kind of medical institutions to Urine in Patients
During sampling, facilitate patient voluntarily to sample, simplify medical worker's sampling link, can be connected urine sample gathering and checked operation are compact
It is closed to carry out, and simple structure, the disposable humoral indwelling device of handling ease.Belong to Medical sampling engineering device technique field.
Background technology
Urine test belongs to one of medical institutions' three big routine inspections of clinic.Current medical institutions are to patient urine sample
Collection container is most of to use plastics or papery urine cup.Patient is extremely inconvenient when lavatory is sampled, after open censorship, medical worker
It is sampled again and is put into test tube chemical examination.Whole process is susceptible to splash, and giving forth fragrance is extremely unhygienic, pollutes environment.
Therefore, many products for urine enclosed sampling are developed, although title differs, product form is basic
All it is conducting element and liquid storage component, conducting element is made up of chamber pot container and connector, and liquid storage component is made up of check valve and test tube.
In order to water conservancy diversion urine in closed test tube, it is necessary to set vent, the air in discharge test tube could enter urine catheterization
Closed test tube.Layout is improper, and vent has reformed into overflow duct, pollutes test tube.It is limited to the position peace of vent
Row, most of patent does not have realizability.It is relatively good to have disposable obturator disclosed in Chinese patent CN104907112B
A kind of automatic closing type urine liquid sampler disclosed in liquid indwelling device and CN205958290U.But be located at for vent epimere by the former
In chamber pot container, chamber pot container top is obliquely extended to, and the shutter body for blocking test tube is provided with product bottom, prevented
Overflow；The latter's perforate on test tube hermetic unit, increases the composition and complexity of test tube hermetic unit, and having in sampling process can
Overflow can occur.Two above invention is all due to the location problem of vent, and complex structure, work efficiency is not high.Above-mentioned these urine
The technical elements of liquid sampling product patent more or less have defect, it is necessary to be improved.
The content of the invention
The present invention is intended to provide when a kind of medical institutions are to Urine in Patients inspection by sampling, facilitating patient voluntarily to sample, simplify
Medical worker samples link, can be connected urine sample gathering and checked operation are compact closed and carry out, and simple structure, handling ease
Disposable humoral indwelling device.
Technical solution of the invention is as follows：
Disposable humoral indwelling device, including infundibular body, connector, check valve and test tube, infundibular body and connector one into
Shape, the connector is provided with connecting pole, and flow-guiding channel is provided with connecting pole, and the mouth of pipe of test tube is provided with check valve, check valve
It is connected with connecting pole, by flow-guiding channel access test tube, it is characterised in that：There is insertion in the check valve and test tube junction
Hole inside and outside test tube, air can be discharged from hole, and urine is but because tension force effect cannot be passed therethrough.
The advantage of above-mentioned technical proposal is that mould structure is simple, and assembling product is convenient, is greatly enhanced work efficiency.
Further technical scheme is have groove on the outer wall of check valve, engages to form hole with the inwall of test tube.
The technical scheme of another step is have groove on the inwall of test tube, engages to form hole with the outer wall of check valve.
The technical scheme of another step is that the open top edge of infundibular body is provided with sagging antifouling eaves.
The advantage of above-mentioned technical proposal is, when urine covers the top of infundibular body, can be dripped along antifouling eaves, it is to avoid stream
To tubing surfaces.
Preferred technical scheme is that connector is provided with connect cover, and connect cover is connected with test tube.
Brief description of the drawings
The present invention is described in further details below with reference to drawings and Examples.
Accompanying drawing 1 is the structural representation of first embodiment of the invention.
Accompanying drawing 2 is the structural representation of second embodiment of the invention.
Each sequence number is respectively in figure：1st, infundibular body；2nd, connector；3rd, check valve；4th, test tube；11st, antifouling eaves；12nd, handle；
21st, connecting pole；22nd, connect cover；23rd, flow-guiding channel；31st, valve element；32nd, hole；321st, air intake.
Specific embodiment
Referring to accompanying drawing 1, the disposable humoral indwelling device shown in first embodiment of the invention, including infundibular body 1, connector
2nd, check valve 3 and test tube 4, infundibular body 1 are integrally formed with connector 2, and the connector 2 is provided with connecting pole 21, connecting pole 21
In be provided with flow-guiding channel 23, the mouth of pipe of test tube 4 is provided with check valve 3, and check valve 3 is connected with connecting pole 21, by flow-guiding channel 23
Access in test tube 4, there is the hole 32 inside and outside insertion test tube 4 in the junction of test tube 4 and check valve 3, for discharging test tube 4 in
Air, sectional area is 0.75mm at the air intake 321 of hole 322.During sampling, in the insertion check valve 3 of connecting pole 21, both it
Between interference fit, connecting pole 21 compresses valve element 31, and valve element 31 is deformed, and " one " the font crack in the middle of valve element 31 is opened and become
Into passage, the handle 12 of infundibular body 1 is caught, during urine discharged into infundibular body 1, urine is flowed into test tube 4 through flow-guiding channel 23, together
When compressing air from hole 32 discharge test tube 4 outside.When urine liquid level once exceed hole 32 air intake 321, liquid
Power is just had an effect, and prevents urine from entering hole 32.Sampling terminates, and pours out unnecessary urine, and appropriate urine is left in test tube 4
Liquid, extracts connecting pole 21, and be retained in urine sample in test tube 4, the test tube equipped with urine sample by the automatic rebounding of valve element 31 closure
4 can be directly used for follow-up chemical examination.
Referring to accompanying drawing 2, second embodiment of the invention and the difference of one embodiment are that connector 2 is provided with and is connected
Cover 22, connect cover 22 is connected with test tube 4.
