Description
Technical Field
The utility model relates to the field of medical equipment, concretely relates to safe blood sampler.
Background
The hemostix generally comprises blood taking needle and blood taking tube, and in prior art, the blood taking tube generally adopts vacuum blood taking tube to take a blood sample to the patient, and the blood taking needle generally adopts the vein blood taking needle, and this kind of blood taking needle both ends all are the felting needle, and one end is used for impaling the mouth of pipe of vacuum blood taking tube, and the other end then is used for impaling human skin and blood vessel to this comes the blood sampling.
And to the patient in severe ward, need carry out a lot of blood drawing inspection to it a day, if all use the blood taking needle at every turn, cause the injury to patient's health easily, consequently adopt to keep somewhere the syringe needle more and avoid general blood taking needle to come to take a blood sample to patient, and to keeping somewhere the syringe needle, the blood sampling mode usually is for being connected with medical three-way valve behind keeping somewhere the syringe needle, reuse syringe carries out the blood sampling to patient, such blood sampling method, though can not cause the secondary damage to patient because of the blood taking needle, but when utilizing the syringe to draw blood, the dynamics is unable even, therefore also probably because of the inequality of dynamics, and the sample quality who leads to taking a blood can not have fine assurance. In addition, since both ends of a general intravenous blood collection needle are needles, there is a certain risk to some people who are not very skilled, and therefore, when using the blood collection needle, great care is required,
SUMMERY OF THE UTILITY MODEL
To the deficiency of the prior art, the utility model provides a safe blood sampler.
In order to achieve the above purpose, the technical scheme of the utility model is that:
the utility model provides a safe blood sampler, is including keeping somewhere the syringe needle, it is connected with the connecting pipe to keep somewhere the syringe needle, the connecting pipe other end is connected with medical three-way valve, still includes vacuum test tube and blood taking needle, the blood taking needle is including setting up at the felting needle of one end, setting up at the connector of the other end and the hose of connecting felting needle and connector, the connector is with the interface connection of medical three-way valve, the mouth of pipe that the felting needle is used for impaling vacuum test tube (2) is sampled.
Furthermore, the connector is a cylinder, and one end of the cylinder is hermetically connected with the hose.
Furthermore, the diameter of one end of the cylinder, which is far away from the hose, is smaller than the inner diameter of the medical three-way valve interface, and the diameter of one end of the cylinder, which is close to the hose, is larger than the inner diameter of the medical three-way valve interface. Through the arrangement of the vacuum blood collection tube, the cylinder can extend into the connector of the medical three-way valve, and the arrangement of the cylinder with one thick side and one thin side can effectively seal the space of the cylinder, so that the vacuum blood collection tube can exert the effect of the vacuum blood collection tube to collect blood for a patient.
Furthermore, a threaded cover used for being in threaded connection with the medical three-way valve interface is arranged on the outer side of the cylinder. Set up the screw cap, can connect the drum on medical three-way valve steadily, and need not nurse's hand and fix it, guarantee the sealing connection of connector and medical three-way valve.
Furthermore, the surface of the threaded cover is provided with anti-skid lines.
Further, the threaded cap is rotatably connected to the cylinder.
Compared with the prior art, the utility model, have following advantage:
the utility model discloses a connector replaces the felting needle of venous blood taking needle one end, makes it when using, is difficult for causing the injury to patient or medical personnel, reduces its probability of accidental injury to the connector can be connected with medical three-way valve, and then makes the blood sampling can carry out the work of drawing blood through the vacuum test tube, compares traditional use syringe extraction, and is more stable and convenient.

Detailed Description
In order to make the above objects, features and advantages of the present invention more comprehensible, the present invention is described in detail with reference to the accompanying drawings and the detailed description.
Examples
As shown in figure 1, a safe blood sampler, including keeping somewhere syringe needle 11, it is connected with connecting pipe 12 to keep somewhere syringe needle 11, the connecting pipe 12 other end is connected with medical three-way valve 13, still includes vacuum blood collection tube 2 and blood taking needle 3, blood taking needle 3 is including setting up the felting needle 31 of one end, setting up the connector 33 at the other end and the hose 32 of connecting felting needle 31 and connector 33, connector 33 and medical three-way valve 13's interface connection, felting needle 31 is used for puncturing the mouth of pipe of vacuum blood collection tube 2(2) and takes a blood sample.
As shown in fig. 2, the connector 33 is a cylinder, and one end of the cylinder is hermetically connected to the hose 32, thereby ensuring the sealing property of the lancet 3. The diameter of the end of the cylinder far away from the hose 32 is smaller than the inner diameter of the interface of the medical three-way valve 13, and the diameter of the end of the cylinder near the hose 32 is larger than the inner diameter of the interface of the medical three-way valve 13. Through the arrangement of the vacuum blood collection tube, the cylinder can extend into the interface of the medical three-way valve 13, and the arrangement of the cylinder with the thick side and the thin side can effectively seal the space, so that the vacuum blood collection tube 2 can exert the efficacy to collect blood for a patient.
In addition, the outer side of the cylinder is provided with a threaded cap 331 for threaded connection with the interface of the medical three-way valve 13, the thread of the threaded cap 331 is internal thread, and one end of the threaded cap 331 close to the hose 32 is rotatably connected with the surface of the cylinder, so that the cylinder and the threaded cap 331 can rotate relatively and can not displace. The surface of the cylinder is protruded with a circle of convex edge 332, and the convex edge 332 is embedded in the screw cap 331, thereby realizing the screw connection. The surface of the screw cap 331 is provided with anti-slip lines 333, and the pattern of the anti-slip lines 333 is a strip line consistent with the axial direction of the screw cap 331.
Because two of the three connectors of the medical three-way valve 13 are external threads, the cylinder can be stably connected to the medical three-way valve 13 by adding the threaded cap 331 with internal threads, without fixing the medical three-way valve by hands of a nurse, thereby ensuring the airtight connection between the connector 33 and the medical three-way valve 13.
When the blood sampling device is used, the connector 33 and the medical three-way valve 13 are connected, the threaded cover 331 is screwed, the cylinder of the connector is abutted against the interface of the three-way valve to keep airtight, the puncture needle 31 is pricked into the vacuum blood sampling tube 2 after the medical three-way valve 13 is communicated with a corresponding channel, blood sampling can be started, and after the blood sampling is finished, the channel is closed by the medical three-way valve 13, and the connector 33 is detached, so that the whole blood sampling process can be completed. Whole process is simple, convenient operation to compare traditional vein blood taking needle 3, safer, difficult accidental injury patient or nurse cause the infection.
The above embodiments are only for illustrating the technical concept and features of the present invention, and the purpose thereof is to enable those skilled in the art to understand the contents of the present invention and to implement the present invention, which cannot limit the protection scope of the present invention. All equivalent changes and modifications made according to the spirit of the present invention should be covered by the protection scope of the present invention.
