Abstract
The utility model discloses needleless sample connections, including vertical tube, sampling transverse tube, snorkel, top cover and air-permeable anti-bacterial film.The bottom end of snorkel is connected with the side of vertical tube；Snorkel has central through hole, and the central through hole of snorkel is connected to the pore of vertical tube.Top cover is fixed on snorkel, and blocks the front of snorkel central through hole, and the side of top cover is equipped with vent openings.Air-permeable anti-bacterial film is set in the central through hole of snorkel, and outside air passes sequentially through vent openings and air-permeable anti-bacterial film enters in the pore of vertical tube.The utility model can be avoided in the vertical tube that urine is trapped in sample connection in sufferer urination, and can prevent syringe from accidentally pricking, and reduce the probability that bacterium infection occurs for sufferer.
Description
Technical field
The utility model relates to medical instrument more particularly to needleless sample connections.
Background technique
The sample connection that the well known urine for extracting sufferer carries out analytical test intersects vertically by vertical tube, with the vertical tube
Sampling transverse tube and the Elastic valve core composition that is arranged in the sampling transverse tube, the top surface of Elastic valve core is equipped with notch, is not having
In the case where external force, which keeps the state of sealing.In actual use, one end of vertical tube and insertion be in patient body
Catheter is connected, and the other end is connected with one end of urine conveyance tube, and the other end of urine conveyance tube can be connected to urinal or other
Collection vessel.When the urine for needing to extract patient carries out analytical test, feather valve is inserted into the head of syringe by medical staff
The notch of core, Elastic valve core deform due to by external force, open notch.After the extraction for completing urine, medical staff will be injected
Device is extracted from Elastic valve core, using the elasticity of Elastic valve core itself, is re-closing off notch.
Urine sampling is carried out using existing sample connection, when sufferer urination closes to an end, bladder pressure is smaller, it is easy to
There is the phenomenon that urine is trapped in the vertical tube of sample connection and can not swimmingly flow to downstream, occurs carefully to increase sufferer
The probability of bacterium infection.
Summary of the invention
It can be avoided the urine in sufferer urination the technical problem to be solved by the utility model is to provide one kind to be detained
In the vertical tube of sample connection and it can prevent syringe from missing the needleless sample connection pricked.
In order to solve the above technical problems, the utility model uses following technical scheme:
Needleless sample connection, including vertical tube and sampling transverse tube；The needleless sample connection further includes snorkel, top cover and breathes freely
Antibacterial film；The bottom end of snorkel is connected with the side of vertical tube；Snorkel has central through hole, the central through hole and vertical tube of snorkel
Pore connection；Top cover is fixed on snorkel, and blocks the front of snorkel central through hole, and the side of top cover is equipped with ventilation
Opening；Air-permeable anti-bacterial film is set in the central through hole of snorkel；Outside air passes sequentially through vent openings and air-permeable anti-bacterial film
It enters in the pore of vertical tube.
After adopting the above technical scheme, the utility model has the advantage that
1, it is equipped with according to the needleless sample connection of an embodiment of the present invention in the side of vertical tube and is connected with vertical tube
Venthole makes the pressure energy in vertical tube maintain the level of external pressure, thus even if sufferer urination close to an end, bladder
When pressure is smaller, it also can guarantee urine in vertical tube swimmingly flow further downstream, be trapped in sample connection without urine
Vertical tube in situation, reduce sufferer occur bacterium infection probability；
2, top cover being equipped with according to the needleless sample connection of an embodiment of the present invention, top cover is fixed on snorkel, and
The front of snorkel central through hole is sheltered from, so as to avoid medical staff's mistake that syringe is inserted into snorkel, is incited somebody to action
The situation that air-permeable anti-bacterial film in snorkel punctures, and then avoid urine and come out from air-permeable anti-bacterial film breakage splash, it causes
Pollution to environment also reduces the infected probability of patient.
