IV catheter with blood drawer

technical field

The utility model relates to the technical field of medical instruments, in particular to an instrument capable of collecting blood and transfusion.

Background technique

The intravenous indwelling needle is a medical device used for intravenous infusion therapy. The indwelling needle of the existing venous indwelling needle is usually made of plastic material. It can be used with a puncture needle to smoothly penetrate into the vein of the human body and serve as an intravenous indwelling infusion needle. role. Currently commonly used blood collection needles are different from venous indwelling needles. Both ends of the blood collection needle are metal puncture needles, and one end is inserted into the vein and the other end is inserted into a vacuum blood collection tube for blood collection. Currently, intravenous indwelling needles are mainly used for infusion, and blood samples taken from veins are collected in venous vessels with vacuum blood collection tubes and blood collection needles. Blood collection and infusion are performed separately, and secondary venipuncture is performed, which causes suffering for patients.

Utility model content

In view of this, the technical problem to be solved by the utility model is to provide a venous indwelling needle with a blood collection device, which can be used for both blood collection and infusion, and only one venipuncture is required to reduce the suffering of patients.

The utility model solves the above-mentioned technical problems by the following technical means:

The venous indwelling needle with a blood collection device of the utility model includes a puncture needle assembly, an indwelling sleeve assembly and a needle point protective cap, and the puncture needle assembly includes a puncture needle seat and a puncture needle tube, and also includes a non-puncture type blood collection device. The indwelling sleeve assembly includes a four-way catheter seat, an infusion set, an indwelling needle catheter and a blood collection device connector. Internally connected lancet assembly.

Further, the connecting piece of the blood collection device is formed by connecting a small tube and a large tube, the small tube is connected with the catheter base of the indwelling needle, and the large tube is connected with the catheter through a joint.

Further, the large pipe is threadedly connected with a joint, an internal thread is provided inside the large pipe, and an external thread matching the internal thread is provided outside the joint.

Further, the small tube is made of soft plastic, the large tube is made of hard plastic, and the small tube is clamped with a stop clip.

Beneficial effects of the present utility model: the venous indwelling needle with a blood collection device of the present utility model includes a puncture needle assembly, an indwelling sleeve assembly and a needle point protective cap, and the puncture needle assembly includes a puncture needle seat and a puncture needle tube, and also includes A non-puncture blood collection device, the indwelling sleeve assembly includes a four-way catheter seat, an infusion assembly, an indwelling needle catheter and a blood collection device connection piece, and the non-puncture type blood collection device includes a joint communicated with the blood collection device connection piece, and connected to the blood collection device A catheter connected by a connector and a blood collection needle assembly connected to the end of the catheter. When it is necessary to collect blood from the patient, first use the puncture needle tube to puncture, then pull out the puncture needle tube, the blood collection needle assembly is connected to the blood collection tube, and a quantitative blood sample is taken through the blood collection tube, and the infusion is performed after the blood collection is completed. Blood collection and infusion were completed, which relieved the suffering of patients.

Description of drawings

Below in conjunction with accompanying drawing and embodiment the utility model is described further.

Fig. 1 is the structural representation of the utility model.

detailed description

The utility model will be described in detail below in conjunction with accompanying drawing, as shown in Figure 1:

The venous indwelling needle with blood collection device of the present utility model comprises a puncture needle assembly 1, an indwelling sleeve assembly 2 and a needle point protective cap 3, and the puncture needle assembly 1 includes a puncture needle seat 11 and a puncture needle tube 12, and also includes a Puncture type blood collection device 4, the indwelling sleeve assembly 2 includes a four-way catheter seat 21, an infusion assembly 22, an indwelling needle catheter seat 23 and a blood collection device connector 24, and the non-puncture type blood collection device 4 includes a connection part with a blood collection device 24, a joint 41 connected to the joint 41, a conduit 42 connected to the joint 41, and a blood collection needle assembly 43 connected to the end of the conduit 42. A non-puncture blood collection device is installed on the venous indwelling needle. When the patient needs to collect blood, first use the puncture needle tube to puncture, and then pull out the puncture needle tube. The blood collection needle assembly is connected to the blood collection tube, and the quantitative blood sample is taken through the blood collection tube to complete the blood collection After the infusion, blood collection and infusion can be completed with only one puncture, which reduces the pain of the patient.

As a further improvement of the above technical solution, the blood collection device connector 24 is formed by connecting a small tube 241 and a large tube 242 , the small tube 241 is connected to the indwelling needle catheter base 23 , and the large tube 242 is connected to the catheter 42 through the joint 41 . The large tube 242 and the joint 41 are detachably connected or fixedly connected. This embodiment adopts a detachable connection. The advantage of the detachable connection is that after the blood collection step is completed, the non-puncture blood collection device can be removed to save space.
