During the inclined insertion process, the medical staff's hands are likely to come into contact with the patient's body. At the same time, the patient's body may affect the medical staff's hand movements, hindering their puncture work and making it difficult for the puncture needle to accurately find the puncture point.

[0004] In summary, the present invention provides a novel venipuncture combination device to solve the above problems. Utility Model Content

[0005] In order to solve the above technical problems, the utility model provides the following technical solutions:

[0006] A novel venous puncture combination device comprises a barrel, both sides of which are fixedly connected to taking pieces, the front side of the barrel is detachably connected to a syringe, the back side of the barrel is fixedly connected to a needle tube, the front side of the needle tube is fixedly connected to an auxiliary tube, the inner cavity of the auxiliary tube is detachably connected to a probe, the opening at the rear end of the probe is crescent-shaped, the rear end of the probe extends to the inner cavity of the needle tube and is detachably connected to the inner cavity of the needle tube, and the front side of the probe is fixedly connected to a pushing piece.

[0007] Furthermore, in the present invention, the length of the syringe is 5 cm, and the length of the probe is 8 cm.

[0008] Furthermore, in the present invention, the angle between the cylinder and the needle tube is 120 degrees.

[0009] Furthermore, in the utility model, the surface of the auxiliary tube is provided with threads, the surface of the auxiliary tube is threadedly connected with a sealing cover, and the inner cavity of the sealing cover is provided with a sealing gasket.

[0010] Furthermore, in the utility model, the inner cavity of the needle tube is provided with a sealing ring, and the inner wall of the sealing ring is slidably connected to the surface of the probe.

[0011] Beneficial effects: The utility model has the following beneficial effects:

[0012] The utility model is used to form a device body by arranging a barrel, a syringe, a needle tube and a probe, wherein the needle tube and the probe are used to pierce the skin, and the syringe is used to draw blood or inject liquid medicine. The provision of a picking piece makes it easy to pick up the barrel. Since there is an angle of 120 degrees between the barrel and the needle tube, a certain distance can be maintained between the hands of medical staff and the skin of the patient during the puncture, thereby preventing the puncture position from being shifted due to accidental contact with the patient's body during the puncture process, so that the probe can accurately find the puncture point. Since the opening at the rear end of the probe is crescent-shaped and has symmetrical spikes above and below, it can better match the surface of the probe during the process of piercing the skin, further improving the accuracy of the puncture.

[0021] Example 1

[0022] like Figure 1-5 As shown, it is the first embodiment of the utility model, which provides a novel venous puncture combination device, including a barrel 1, both sides of the barrel 1 are fixedly connected with a taking piece 2, the front of the barrel 1 is detachably connected with a syringe 3, the back of the barrel 1 is fixedly connected with a needle tube 4, the front of the needle tube 4 is fixedly connected with an auxiliary tube 5, the inner cavity of the auxiliary tube 5 is detachably connected with a probe 6, the opening at the rear end of the probe 6 is crescent-shaped, the rear end of the probe 6 extends to the inner cavity of the needle tube 4, and is detachably connected to the inner cavity of the needle tube 4, and the front of the probe 6 is fixedly connected with a push piece 7.

[0023] like Figure 1-5 As shown, the barrel 1, the syringe 3, the needle tube 4 and the probe 6 are used to constitute the main body of the device, wherein the needle tube 4 and the probe 6 are used to pierce the skin, the syringe 3 is used to draw blood or inject anesthetics, and the barrel 1 can be easily taken by the taking piece 2.

[0024] Example 2

[0025] Reference Figure 1 , which is the second embodiment of the utility model, and this embodiment is based on the previous embodiment.

[0026] In this embodiment, the length of the syringe 3 is 5 cm, and the length of the probe 6 is 8 cm.

[0027] The angle between the cylinder body 1 and the needle tube 4 is 120 degrees.

[0028] like Figure 1 As shown, since there is an angle of 120 degrees between the barrel 1 and the needle tube 4, when performing the puncture, the medical staff's hand can be kept at a certain distance from the patient's skin, thereby preventing the puncture position from being shifted due to accidental contact with the patient's body during the puncture process, so that the probe 6 can accurately find the puncture point. Since the opening at the rear end of the probe 6 is crescent-shaped and has symmetrical spikes on the upper and lower parts, it can better match the surface of the probe 6 during the process of piercing the skin, further improving the accuracy of the puncture.

[0029] Example 3

[0030] Reference Figure 4 , which is the third embodiment of the utility model, and this embodiment is based on the previous two embodiments.

The sealing ring 10 is used to protect the gap between the needle tube 4 and the probe 6 to prevent blood from seeping out through the auxiliary tube 5 during the puncture process.

[0034] When in use, the barrel 1 can be taken by taking the taking piece 2, and the needle tube 4 can be inserted into the patient's skin. Since there is an angle of 120 degrees between the barrel 1 and the needle tube 4, when performing the puncture, the medical staff's hand can be at a certain distance from the patient's skin, thereby preventing the puncture position from being offset due to accidental contact with the patient's body during the puncture process, so that the probe 6 can accurately find the puncture point. Since the opening at the rear end of the probe 6 is crescent-shaped and has symmetrical spikes on the upper and lower parts, it can better match the surface of the probe 6 during the process of piercing the skin, further improving the accuracy of the puncture. After the insertion is completed, the probe 6 can be driven to move by pushing the pushing piece 7, so that the probe 6 can penetrate the skin for further puncture. After the puncture is completed, the probe 6 can be taken out by pulling the pushing piece 7. After taking it out, the sealing cover 8 is installed on the rear end of the auxiliary tube 5 to seal it, and then the anesthetic can be injected using the syringe 3.
