Description
Technical Field
The utility model relates to the technical field of medical equipment, in particular to helping hand formula blood sampling device.
Background
Blood collection and chemical examination are the clinical disease monitoring means of a commonly used, and human blood directly samples, and the nurse directly adopts through vacuum sampling device usually, and current vacuum blood sampling device includes parts such as vacuum blood collection tube and blood taking needle basically, and the negative pressure through vacuum blood collection tube comes the blood sampling, utilizes the negative pressure, and blood flows into in the vacuum blood collection tube through the blood taking needle is automatic.
However, in actual use, the negative pressure of the vacuum blood collection tube is insufficient, so that blood cannot enter the vacuum blood collection tube, the blood collection tube needs to be replaced again, blood is collected again, pain and trouble are brought to a patient, time is delayed, and working efficiency is affected.
SUMMERY OF THE UTILITY MODEL
In view of the blood sampling device negative pressure is not enough among the prior art, causes repeated acupuncture, and is inefficient, the problem of troublesome poeration, the utility model provides a helping hand formula blood sampling device, the technical problem that solve are that help blood sampling is come through supplementary negative pressure, satisfy disposable blood sampling and target in place, raise the efficiency.
The technical scheme of the utility model as follows: the utility model provides a helping hand formula blood sampling device, includes the blood sampling syringe needle, the rear end of blood sampling syringe needle is connected with coupling hose, coupling hose's rear end is connected with the tee junction tube head, the other two ways of tee junction tube head are connected with respectively leads blood needle and syringe, the three routes department of joining of marriage of tee junction tube head is provided with the ball valve.
Further, preferably, a needle holder is provided at the rear of the blood collection needle.
Further, preferably, the three-way connector head is connected to the connection hose through a first connection pipe.
Preferably, a second connecting pipe used for being connected with the injector is further arranged on the three-way connecting pipe head.
Further, preferably, the second connection pipe is made of rubber.
Has the advantages that: the utility model discloses think about novelty, reasonable in design and the operation of being convenient for, the utility model relates to a set up the tee bend pipeline and utilize the ball valve through leading the blood end for when taking a blood sample, can provide the negative pressure of replenishment for drawing a blood through the syringe, make to draw a blood can once succeed, alleviate patient's misery, improve the efficiency of drawing a blood.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
Detailed Description
The invention will be further explained with reference to the following figures and examples:
as shown in fig. 1, a power-assisted blood sampling device has a blood sampling needle 1, the rear end of the blood sampling needle 1 is connected with a connecting hose 2, the rear end of the connecting hose 2 is connected with a three-way connector head 3, the other two ways of the three-way connector head 3 are respectively connected with a blood guide needle 4 and an injector 5, and the three-way intersection of the three-way connector head 3 is provided with a ball valve 6.
The principle of the utility model is as follows: blood sampling needle 1 is used for the blood sampling, and blood flows into three-way connector head 3 position through coupling hose 2, then under the normal circumstances that has the negative pressure, enters into the vacuum test tube through three-way connector head 3 and blood guide needle 4. At this time, the ball valve 6 is in a state of keeping the connection from the connection hose 2 to the blood introducing needle 4. If the negative pressure of heparin tube is not enough, can not directly take a blood sample, then rotate the valve of ball valve 6, draw blood through syringe 5, supply the negative pressure, then rotate ball valve 6 again for blood enters into the heparin tube the inside.
In the specific implementation process, preferably, a needle holder 7 is arranged at the rear part of the blood sampling needle 1. The needle holder 7 is arranged to better hold the needle head when the needle is inserted for blood sampling.
In the specific implementation, the three-way connector head 3 is preferably connected to the connection hose 2 via a first connection tube 8. By means of the first connecting tube 8, the connection of the three-way connector stub 3 and the connecting hose 2 can be made more convenient and secure.
In the specific implementation process, preferably, the three-way connector head 3 is further provided with a second connecting tube 9 for connecting with the syringe 5. The second connecting pipe 9 is arranged to ensure that the connection between the three-way connector head 3 and the injector 5 is more convenient and stable and is not easy to leak gas.
In the specific implementation process, the second connecting pipe 9 is preferably made of rubber. The second connecting pipe 9 is made of rubber, so that the second connecting pipe 9 is connected with the injector 5 more tightly and is not easy to leak air.
Combine above all technical scheme, the utility model discloses when specifically using, the user pricks the needle blood sampling through gripping needle holder 7, then adjusts ball valve 6 to in pricking the vacuum tube with leading blood needle 4, make blood enter into the vacuum blood sampling pipe through coupling hose 2. Under the condition that the vacuum of the vacuum blood collection tube is not enough, the ball valve 6 is rotated firstly, so that the connecting hose 2 is communicated with the injector 5, then the injector 5 is used for supplementing negative pressure, the vacuum pumping is carried out, when blood is to be pumped out, the ball valve 6 is rotated again, and the blood is guided to enter the blood collection vacuum tube. Convenient and fast, efficient.
The utility model discloses in concrete use, because artery is invisible, need find artery through response or perspective device earlier, the reuse after the location the utility model discloses the puncture is taken out blood. In order to prevent blood coagulation, sodium glycinate can be put into the utility model.
The foregoing has described in detail preferred embodiments of the present invention. It should be understood that numerous modifications and variations can be devised by those skilled in the art in light of the teachings of the present invention without undue experimentation. Therefore, the technical solutions that can be obtained by a person skilled in the art through logic analysis, reasoning or limited experiments based on the prior art according to the concepts of the present invention should be within the scope of protection defined by the claims.
