Description

A disposable catheter connected to a blood sampling device

Technical Field

The utility model relates to a disposable catheter-connected blood sampling device, belonging to the technical field of medical equipment.

Background Art

Venous blood sampling and infusion are common technical operations in clinical nursing work. In actual clinical operations, some patients not only need to draw blood samples for testing, but also need infusion at the same time. Usually, infusion and blood sampling are performed separately, and nurses need to perform two venous punctures for patients, which not only increases the labor intensity of nurses, but also increases the pain of patients.

To this end, a Chinese patent document with publication number CN203598306U discloses a disposable dual-purpose needle for venous blood collection and infusion, which is characterized in that it includes a venous puncture needle, a hose, a Y-way, a three-way valve, a Luer female connector, and a bottle stopper puncture needle. One end of the hose is connected to the venous puncture needle, and the other end is connected to the Y-way. The bottom of the three-way valve is stuck in the Y-way, and the top remains outside the Y-way. One end of the Y-way is connected to a section of the hose, and the end of the hose is connected to the Luer female connector. The other end of the Y-way is connected to another section of the hose, and the end of the hose is connected to the bottle stopper puncture needle.

For patients who only need one infusion and one blood draw, this dual-purpose needle can reduce the number of venipunctures and relieve the pain of patients. For patients who need multiple infusions, indwelling needles are usually used clinically to reduce the number of venipunctures, thereby reducing the workload of nurses and relieving the pain of patients. However, this dual-purpose needle cannot be used in conjunction with an indwelling needle to achieve blood draw.

Utility Model Content

In order to solve the above technical problems, the utility model provides a disposable catheter-connected blood sampling device.

The utility model is realized through the following technical solutions:

A disposable catheter-connected blood collector comprises a three-way hose, wherein a bottle stopper puncture needle is arranged at a first port of the three-way hose, a female Luer connector is arranged at a second port, and a syringe connector is arranged at a third port.

DETAILED DESCRIPTION

The technical solution of the utility model is further described below, but the scope of protection required is not limited to the description.

As shown in Figures 1 and 2, the disposable catheter-connected blood collector described in the utility model includes a three-way hose 1, a bottle stopper puncture needle 2 is installed at the first port of the three-way hose 1, a female Luer connector 3 is installed at the second port, and a syringe connector 5 is installed at the third port.

The three-way hose 1 is Y-shaped.

The three-way hose 1 includes a first hose 10, a second hose 11 and a third hose 12, one end of which is connected and communicated with each other. When in use, the bottle stopper puncture needle 2 is installed at the end of the first hose 10, the female Luer connector 3 is installed at the end of the second hose 11, and the syringe connector 5 is installed at the end of the third hose 12.

A flow-stop clamp B8 is installed on the first hose 10 . The flow-stop clamp B8 is used to control the flow of the fluid in the first hose 10 .

A stopper clamp A7 is installed on the third hose 12. The stopper clamp A7 is used to control the flow of the fluid in the third hose 12.

A sealing plug 4 is installed on the female Luer connector 3.

The sealing plug 4 is threadedly connected to the female Luer connector 3. The sealing plug 4 is used to seal the female Luer connector 3.

A plug 6 is installed on the syringe connector 5 . The plug 6 is used to seal the syringe connector 5 .

The disposable catheter-connected blood collector of the utility model has the following working principle or use process:

Step 1: Move the stopper clamp B8 to a position away from the bottle stopper puncture needle 2, and then clamp and close the first hose 10 by the stopper clamp B8;

Step 2: Remove the sealing plug 4 and connect the female Luer connector 3 to the male Luer connector on the patient's indwelling needle, central catheter or arterial catheter;

Step 3, remove the plug 6, insert the end of the syringe away from the piston rod into the syringe connector 5, and draw 5ml to 10ml of blood through the syringe. The main reason is that the first 5ml to 10ml of blood drawn from the patient cannot be used as a test sample;

Step 4: Move the stop clamp A7 to a position away from the syringe connector 5, and clamp and close the third hose 12 by the stop clamp A7;

Step 5: puncture the rubber sleeve needle end of the bottle stopper puncture needle 2 into the vacuum blood collection tube, then loosen the stopper clamp B8 to make the first hose 10 conductive, and blood enters the vacuum blood collection tube under the action of negative pressure to achieve blood collection;

Step 6: After the blood sampling is completed, the first hose 10 is clamped and closed by the stop clamp B8, and the stop clamp A7 is loosened to make the third hose 12 conductive;

Step 7: Push the blood in the syringe back into the patient's body, and then inject isotonic saline into the patient's body through another syringe to seal the tube;

Step 8: Separate the female Luer connector 3 from the male Luer connector on the patient's indwelling needle, central catheter or arterial catheter and other pipelines.
