Description
Technical field
This utility model relates to medical instruments field, is specifically related to one and prevents obscuring liquid pumping needle.
Background technology
At present, when detecting the urine and gastric juice etc. of patient, usually by urine liquid pumping needle and gastric juice liquid pumping needle, urine and gastric juice need be extracted in patient body, current urine liquid pumping needle is similar with gastric juice liquid pumping needle structure, its main distinction is only syringe needle position, different syringe needles is adapted to different occasions, can increase work efficiency, also patient's misery can be slowed down, but for the nurse lacked experience, easily obscure, can exist and extract gastric juice or the risk by gastric juice liquid pumping needle extraction urine with urine liquid pumping needle, this not only can reduce work efficiency, and the misery of patient can be strengthened, in addition, because two kinds of liquid pumping needle structures are similar, when the liquid pumping needle having extracted urine or gastric juice is deposited in together, also being difficult to distinguish fast what fill inside which liquid pumping needle is the gastric juice filled inside urine or which liquid pumping needle, very large not convenient property is brought to subsequent detection.
Utility model content
In view of this, the purpose of this utility model is to provide one and prevents obscuring liquid pumping needle, on the one hand, conscientiously can ensure that specific needles is used for specific drawing liquid occasion, there will not be and obscure, on the other hand, which kind of liquid can distinguish what preserve inside liquid pumping needle is fast, for subsequent detection work brings convenience.
This utility model is solved the problem by following technological means: one is anti-obscures liquid pumping needle, comprise adjustment disk and the syringe be arranged in juxtaposition and standard shaft, described adjustment disk center is provided with the circular hole be socketed with standard shaft, adjustment disk is distributed with the first through hole and the second through hole about center circumference, adjustment disk is also provided be communicated with the first through hole respectively take out urine syringe needle and be communicated with the second through hole take out gastric juice syringe needle, described urine syringe needle of taking out is provided with label with taking out on gastric juice syringe needle, described syringe lower end and adjustment disk end face are tightly connected, syringe is connected with standard shaft by connecting rod, piston is provided with in syringe, described piston is provided with the core bar extended to outside syringe, described standard shaft is provided with projection, the described spring that projects through is connected with standard shaft, described circular hole wall is provided with two grooves mated with projection about adjustment disk center circumference.
Further, described adjustment disk end face is provided with ring-type slideway, and described syringe lower end to be stretched in slideway and is slidably connected with slideway.
Further, described syringe lower end is socketed with sealing ring.
The beneficial effects of the utility model: of the present utility modelly anti-obscure liquid pumping needle, comprise adjustment disk and the syringe be arranged in juxtaposition and standard shaft, described adjustment disk center is provided with the circular hole be socketed with standard shaft, adjustment disk is distributed with the first through hole and the second through hole about center circumference, adjustment disk is also provided be communicated with the first through hole respectively take out urine syringe needle and be communicated with the second through hole take out gastric juice syringe needle, described urine syringe needle of taking out is provided with label with taking out on gastric juice syringe needle, described syringe lower end and adjustment disk end face are tightly connected, syringe is connected with standard shaft by connecting rod, piston is provided with in syringe, described piston is provided with the core bar extended to outside syringe, described standard shaft is provided with projection, the described spring that projects through is connected with standard shaft, described circular hole wall is provided with two grooves mated with projection about adjustment disk center circumference.The anti-of this structure obscures liquid pumping needle, on the one hand, conscientiously can ensure that specific needles is used for specific drawing liquid occasion, there will not be and obscure, and on the other hand, which kind of liquid can distinguish what preserve inside liquid pumping needle is fast, for subsequent detection work brings convenience.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, this utility model is further described.
Fig. 1 is that master of the present utility model sees schematic diagram;
Fig. 2 is that bowing of adjustment disk sees schematic diagram.
Detailed description of the invention
Below with reference to accompanying drawing, this utility model is described in detail, as shown in Figure 1-2: one is anti-obscures liquid pumping needle, comprise adjustment disk 1 and the syringe 2 be arranged in juxtaposition and standard shaft 3, described adjustment disk center is provided with the circular hole 4 be socketed with standard shaft, adjustment disk is distributed with the first through hole 5 and the second through hole 6 about center circumference, adjustment disk is also provided be communicated with the first through hole respectively take out urine syringe needle 7 and be communicated with the second through hole take out gastric juice syringe needle 8, described urine syringe needle of taking out is provided with label 9 with taking out on gastric juice syringe needle, described syringe lower end and adjustment disk end face are tightly connected, syringe is connected with standard shaft by connecting rod 10, piston 11 is provided with in syringe, described piston is provided with the core bar 12 extended to outside syringe, described standard shaft is provided with protruding 13, the described spring 14 that projects through is connected with standard shaft, described circular hole wall is provided with two grooves 15 mated with projection about adjustment disk center circumference.The anti-of this structure obscures liquid pumping needle, when needs extract urine, adjustment disk is rotated around standard shaft, until projection snaps in one of them groove, now, the first through hole is whole is communicated with syringe well, drawing liquid mode routinely can extract urine, in like manner, when gastric juice need be extracted, rotate adjustment disk, projection is made to snap in another groove, now, the second through hole is communicated with syringe, drawing liquid mode routinely can extract gastric juice.Label is provided with owing to taking out urine syringe needle and taking out on gastric juice syringe needle, what label was eye-catching shows which kind of body fluid syringe needle for extracting, and under only having corresponding syringe needle to go to syringe, just drawing liquid operation can be carried out when being combined into the pumping device of complete set with syringe, therefore, the liquid pumping needle of this structure, on the one hand, conscientiously can ensure that specific needles is used for specific drawing liquid occasion, there will not be and obscure, on the other hand, which kind of liquid can distinguish what preserve inside liquid pumping needle is fast, for subsequent detection work brings convenience.
As the further improvement to technique scheme, described adjustment disk end face is provided with ring-type slideway 16, and described syringe lower end to be stretched in slideway and is slidably connected with slideway, and described syringe lower end is socketed with sealing ring 17.The sealing effectiveness of syringe lower end and adjustment disk end face can be ensured so further, avoid in extraction process or leakage in storing process.
What finally illustrate is, above embodiment is only in order to illustrate the technical solution of the utility model and unrestricted, although be described in detail this utility model with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can modify to the technical solution of the utility model or equivalent replacement, and not departing from aim and the scope of technical solutions of the utility model, it all should be encompassed in the middle of right of the present utility model.
