Description

A kind of multi-tube blood collection needle

technical field

The utility model relates to the field of medical equipment, in particular to a multi-tube blood collection needle.

Background technique

In the work of blood bank or hematology, it is often necessary to collect blood samples for laboratory examination. Due to the different quantities of blood samples required for laboratory testing, it is often necessary to collect multiple tubes of blood samples at one time. Existing blood collection needles all have a single-tube structure. After the blood vessel is punctured, the vacuum blood collection tube can only be continuously replaced for blood collection. The blood collection takes a long time and causes great pain. Moreover, the current lancet with a single-tube structure is used in a single way, which cannot be applied to more occasions.

Contents of the invention

The purpose of the utility model is to overcome the shortcomings of the prior art and provide a multi-tube blood collection needle which saves blood collection time, is convenient to use, has strong practicability and wide application range.

In order to solve the above technical problems, the technical solution of the utility model is: a multi-tube blood collection needle, the difference is that it includes a blood collection tube, a venipuncture needle and a plug puncture needle, the blood collection tube is a multi-tube structure, The blood collection tube includes a main conduit and at least two branch pipes, the tail of the main conduit is connected to the tail of the branch pipes through joints, each branch pipe head is provided with a plug puncture needle, and the middle of each branch pipe is provided with a A flow controller, the head of the main catheter is provided with a venipuncture needle.

According to the above technical solution, the tube plug puncture needle is detachably connected with the branch tube.

Compared with the prior art, the beneficial features of the utility model are as follows:

1) The multi-tube blood collection needle can continuously carry out multi-tube blood collection, saving blood collection time and being easy to use;

2) The multi-tube blood collection needle, the plug puncture needle and the branch tube in the blood collection tube are separable structures, which can be directly connected to the infusion set after blood collection, reducing the pain of the patient's secondary puncture;

3) The multi-tube blood collection needle can separate the plug puncture needle from the branch tubes in the blood collection tube when rescuing critically ill patients in clinical work, and connect each branch tube to multiple infusion tubes at the same time to establish multiple veins for patients. Pathway to input different drugs;

4) The multi-tube blood collection needle can be used together with the infusion bag and the blood collection tube in the practice of venous blood collection. The multi-tube structure can be used by multiple people to practice blood collection at the same time.

Description of drawings

Fig. 1 is the overall structure schematic diagram of the utility model embodiment;

Among them: 1-vein puncture needle, 2-tube plug puncture needle, 3-main catheter, 4-branch tube, 5-joint, 6-flow controller.

Detailed ways

The utility model will be described in further detail below through specific embodiments in conjunction with the accompanying drawings.

Please refer to Fig. 1, a kind of multitube blood collection needle of the present utility model, it comprises blood collection tube, venipuncture needle 1 and tube stopper puncture needle 2, described blood collection tube is multitube structure, and blood collection tube comprises a main conduit 3 and at least Two branch pipes 4, the tail of the main pipe 3 is connected with the tail of the branch pipe 4 through the joint 5, the head of each branch pipe 4 is provided with a plug puncture needle 2, and the middle of each branch pipe 4 is provided with a flow control device 6, the head of the main catheter 3 is provided with a venipuncture needle 1.

Specifically, the plug puncture needle 2 is detachably connected to the branch tube 4 .

Using the embodiment of the utility model can continuously carry out multi-tube blood collection, save blood collection time, and is convenient to use; the tube plug puncture needle 2 and the branch tube 4 in the blood collection tube are separable structures, and can be directly connected to the infusion set after the blood collection is completed. Reduce the pain of the patient's secondary puncture; and when rescuing critically ill patients in clinical work, separate the branch tubes 4 in the blood collection tube from the puncture needle 2 of the tube plug and connect multiple infusion tubes at the same time to establish multiple venous accesses for patients Thereby inputting different medicines; In addition, the utility model can also be used together with the infusion bag and the blood collection tube when practicing venous blood collection, and the multi-tube structure of the blood collection tube can be used by many people to practice blood collection at the same time. The utility model is convenient to use, strong in practicability, wide in scope of application, and has better popularization in clinic.

The above content is a further detailed description of the utility model in combination with specific implementation modes, and it cannot be determined that the specific implementation of the utility model is only limited to these descriptions. For a person of ordinary skill in the technical field to which the utility model belongs, without departing from the concept of the utility model, some simple deduction or replacement can also be made, which should be regarded as belonging to the protection scope of the utility model.
