Description
Technical field
The utility model relates to a kind of medical equipment pick-up unit, a kind of specifically medical blood sampling pipeline leak detection apparatus.
Background technology
We know that medical hemostix generally comprises two syringe needles of blood sampling conduit, rear and front end, and there is many places fluid sealant connecting portion the centre.The front end syringe needle is the blood collection needles that has the silica gel sealing cover.During production, require unimpeded everywhere and do not allow to leak gas.Leak detection method commonly used is by hand the silica gel sealing cover on the blood collection needles to be extracted, and is inserted in then on the silicagel pad, is connected on the pipeline that has float type flow meter, checks barometric variation range, judges whether gas leakage.After finishing, again blood collection needles is reinstalled in the silica gel sealing cover.This method need unload and install silica gel sealing cover, complicated operation repeatedly; And require blood collection needles to be connected reliably with silicagel pad, and needing certain pressure, otherwise the possibility of gas leakage is arranged, efficient is low, also exists fluctuation of service property and secondary pollution problem.
Summary of the invention
The utility model technical matters to be solved is the deficiency that overcomes above-mentioned prior art, provides a kind of simple in structure, easy for operation, and is quick, and the single independent operation that gets final product is accomplished stable and safe medical blood sampling pipeline leak detection apparatus.
The technical scheme that the utility model solves the problems of the technologies described above employing is: a kind of medical blood sampling pipeline leak detection apparatus; The detection that comprises a band gas passage connects main body; Detect to connect on the main body flow monitor that is communicated with gas passage is housed; Detect connection main body one end and connect an air connector, it is characterized in that: said detection connects the main body other end and is provided with and the blood collection needles jack, and the diameter of said blood collection needles jack is less than the diameter of silica gel sealing cover on the blood collection needles; During assembling, the silica gel sealing of compression overlaps and blood collection needles jack fitted seal backward.
The said blood collection needles jack of the utility model outer end is the flaring opening that extends out.So that pile up leaving space for the compression of silica gel sealing cover, seal better.
The said flow monitor of the utility model is digital flow monitor.
The utility model makes full use of the silica gel sealing cover of blood collection needles self, pushes blood collection needles to this blood collection needles jack together with the silica gel sealing cover.Utilize the elastic reaction of silica gel sealing cover to compress backward, blood collection needles leaks outside.Silica gel sealing cover and blood collection needles jack fitted seal after the compression through flow monitor, just can detect the gas flow scope of blood collection needles and whole blood sampling pipeline in the short time, realize the fast detecting of medical blood sampling pipeline seepage.After inspection finishes, retreat and extract blood collection needles, the resilience of silica gel sealing cover wraps blood collection needles automatically, plays the seal protection effect.Against existing technologies, the utility model is simple in structure, and is easy for operation, quick, single can the completion by independent operation, and high efficiency, stable and safe, secondary pollution is avoided in not exposing the time of blood collection needles.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further specified.
Fig. 1 is the utility model structural representation.
Label is among the figure: 1. air connector, 2. detect and connect main body, 3. flow monitor, 4. silica gel sealing cover, 5. blood collection needles, 21. blood collection needles jacks.
Embodiment
As can be seen from Figure 1; A kind of medical blood sampling pipeline leak detection apparatus; The detection that comprises a band gas passage connects main body 2, detects to connect on the main body 2 flow monitor that is communicated with gas passage 3 is housed, and detection connects main body 2 one ends and connects an air connector 1.Said detection connects main body 2 other ends and is provided with and blood collection needles jack 21, and blood collection needles jack 21 is communicated with gas passage.The diameter of said blood collection needles jack 21 overlaps 4 diameter less than silica gel sealing on the blood collection needles 5, during assembling, and silica gel sealing cover 4 and blood collection needles jack 21 fitted seal compressed backward.
The said blood collection needles jack of the utility model 21 outer ends are the flaring opening that extends out.So that pile up leaving space for 4 compressions of silica gel sealing cover, seal better.
The said flow monitor 3 of the utility model is digital flow monitor.Compare with common float type flow meter, digital flow monitor not only can be surveyed instantaneous delivery, also can survey integrated flow, and flow value can numeral show, the influence that measured value is not stressed and changes, and measuring accuracy can reach 1%--3%.Can take out signal, be convenient to automatic control.Mounting position is unrestricted.
During the utility model assembling, push blood collection needles 5 to blood collection needles jack 21 together with silica gel sealing cover 4, this hole stops silica gel sealing cover 4; In blood collection needles jack 4; Blood collection needles 5 is worn out silica gel sealing cover 4 and is leaked outside, silica gel sealing cover 4 compression backward, silica gel sealing cover 4 and blood collection needles jack 21 fitted seal after the compression; Can realize blood collection needles 5 so reliably, easily and detect the connection sealing that is connected main body 2, avoid the possibility of leaking gas in the operating process.Through flow monitor 3, just can detect the gas flow scope of blood collection needles and whole blood sampling pipeline in the short time, realize the fast detecting of medical blood sampling pipeline seepage.After inspection finishes, retreat and extract blood collection needles 5, in the process of retreating, silica gel sealing overlaps 4 resiliences, wraps blood collection needles 5 automatically, plays the seal protection effect.Not exposing the time of blood collection needles 5 avoided pollution.The utility model can be installed on the hemostix production line, can realize that the robotization of medical blood sampling pipeline seepage detects.If gas flow does not meet the regulation of flow monitor, the blood sampling pipeline of seepage will be detected, and the blood sampling pipeline of this seepage just can not carried out subsequent processing.
The utility model makes full use of the silica gel sealing cover of blood collection needles self, pushes blood collection needles to this blood collection needles jack together with the silica gel sealing cover.Utilize the elastic reaction of silica gel sealing cover to compress backward; Silica gel sealing cover and blood collection needles jack fitted seal after the compression; Pass through flow monitor; Just can detect the gas flow scope of blood collection needles and whole blood sampling pipeline in the short time, realize the fast detecting of medical blood sampling pipeline seepage.After inspection finishes, retreat and extract blood collection needles, the resilience of silica gel sealing cover wraps blood collection needles automatically, plays the seal protection effect.
The utility model is simple in structure, and is easy for operation, quick, single can the completion by independent operation, and high efficiency, stable and safe, secondary pollution is avoided in not exposing the time of blood collection needles.
Equally, the utility model also is suitable for doing the leak detection of medical infusion pipeline.
