Description

A multifunctional blood collection device

technical field

The utility model belongs to the field of medical equipment, in particular to a multifunctional blood collection device.

Background technique

Clinically, blood collection is divided into two types: arterial blood collection and venous blood collection. Specimens obtained from arterial blood collection and part of venous blood collection are used for blood gas analysis and monitoring, and the requirements for blood collection are relatively high.

In actual clinical work, blood gas analysis often uses BD blood collection needles for arterial and venous blood collection, and venous blood collection needles for venous blood collection. If the same patient needs blood gas analysis and venous blood sample collection at the same time, at least two blood collections must be performed, and repeated puncture is required to the patient, which not only brings physical and mental pain to the patient, but also increases the cost of consumables and increases the cost of workload of nurses.

Utility model content

In order to solve the above problems, the utility model provides a multifunctional blood collection device, which can simultaneously perform blood gas analysis blood collection and venous blood collection through one puncture.

The utility model provides the following technical solutions:

A multifunctional blood collection device, including a negative pressure blood collection tube for venous blood collection and a blood gas blood collection tube for arterial and venous blood collection for blood gas analysis, the blood collection device further comprises a three-way hose, the three-way hose is The three ends are respectively provided with a blood collection needle, a first connection needle and a second connection needle, the first connection needle is connected with the negative pressure blood collection tube, and the second connection needle is connected with the blood gas collection tube.

Preferably, the blood gas collection tube includes a tube body, the top of the tube body is forked to form a first branch end and a second branch end, the first branch end is provided with a push-pull piston rod, and the second branch end is connected to the The second connecting needles are connected.

Preferably, the bottom of the tube body is provided with a threaded interface connected with the blood gas analyzer, and the threaded interface is provided with a threaded cap for sealing it.

Preferably, the blood collection device further includes a sealing clip disposed on the three-way hose for controlling the blood flow path during blood collection.

The beneficial effects of the present utility model are:

1. In the existing clinical blood collection, if the same patient needs blood gas analysis and venous blood sample collection at the same time, blood collection must be performed at least twice, and repeated puncture is required to the patient, which not only brings physical and mental pain to the patient, but also It also increases the cost of consumables and increases the workload of nurses.

The utility model is connected with the blood gas collection tube and the negative pressure blood collection tube through a three-way flexible tube, which realizes the function of puncturing and collecting two kinds of blood samples at one time, reduces the pain of patients, reduces the cost of consumables, and reduces the workload of nurses.

2. Set the sealing clip on the three-way hose, which can effectively control the blood flow path and blood collection volume during blood collection.

Detailed ways

The present utility model will be described in detail below with reference to specific embodiments.

Example 1

As shown in Figure 1, a multifunctional blood collection device includes a negative pressure blood collection tube 1 for venous blood collection and a blood gas collection tube 2 for arterial and venous blood collection for blood gas analysis, and the blood collection device also includes a three-way hose 3. The three ends of the three-way hose 3 are respectively provided with a blood collection needle 4, a first connection needle 5 and a second connection needle 6. The first connection needle 5 is connected with the negative pressure blood collection tube 1, and the The second connecting needle 6 is connected to the blood gas collection tube 2 .

Example 2

On the basis of Embodiment 1, as shown in FIG. 1 , the blood gas collection tube 2 includes a tube body 21 , an anticoagulant for preventing blood coagulation is arranged in the tube body 21 , and the top of the tube body 21 is formed by a fork. The first branch end 22 and the second branch end 23 , the first branch end 22 is provided with a push-pull piston rod 24 , and the second branch end 23 is connected with the second connecting needle 6 .

Example 3

On the basis of Embodiment 1, as shown in FIG. 1 , the bottom of the tube body 21 is provided with a threaded interface 25 connected to the blood gas analyzer, and the threaded interface 25 is provided with a threaded cap for sealing it.

Example 3

On the basis of Embodiment 1, as shown in FIG. 1 , the blood collection device further includes a sealing clip 7 disposed on the three-way hose 3 for controlling the blood flow path during blood collection.

The working process of the present utility model is as follows:

When the patient needs blood gas analysis and venous blood sample collection at the same time, firstly clamp the sealing clip 7 on the tee hose 3 close to the blood gas collection tube 2, and the tee hose 3 is close to the sealing clip 7 on the negative pressure blood collection tube 1. Release, the second connecting needle 6 is inserted into the second branch end 23, the first connecting needle 5 is inserted into the negative pressure blood collection tube 1, and then the blood collection needle 4 is inserted into the patient's venous blood vessel. At this time, the negative pressure in the negative pressure blood collection tube 1 Under the action of the negative pressure blood collection tube 1, the blood enters the negative pressure blood collection tube 1. When the blood volume in the negative pressure blood collection tube 1 is sufficient, clamp the sealing clip 7 on the three-way hose 3 close to the negative pressure blood collection tube 1, and pull out the negative pressure. The first connecting needle 5 on the blood collection tube 1 loosens the sealing clip 7 on the three-way hose 3 close to the blood gas collection tube 2, lifts the push-pull piston rod 24 on the blood gas collection tube 2, and sucks the blood into the blood gas collection tube 2 When the blood volume is sufficient, clamp the sealing clip 7 on the tee hose 3 close to the blood gas collection tube 2, pull out the second connecting needle 6 and the blood collection needle 4, and complete the blood collection work.

The above are only preferred embodiments of the present invention, and are not intended to limit the present invention.
