Abstract

The utility model discloses a venous indwelling needle capable of taking blood, the main structure of which comprises a Y-shaped seat and an isolation puncture plug, a needle sleeve is located below the Y-shape, and a long catheter connecting tube and a puncture needle-introducing tube are respectively located above the Y-shape. The puncture plug is arranged at the mouth of the needle tube of the puncture needle, and the top edge of the isolated puncture plug is provided with a reflexed brim to seal the edge of the mouth of the needle tube. Compared with the prior art, the utility model has the advantages that the patient can take blood from the vein while keeping the venous indwelling needle, which reduces the pain caused by repeated puncture to the patient and reduces the workload of the nurse.

Description

Indwelling needle for blood collection

Technical field

The utility model relates to a medical device, in particular to a venous indwelling needle capable of taking blood.

Background technique

The existing venous indwelling needle is a replacement product of the scalp steel needle, which has the advantages of soft needle sleeve, not easy to damage the blood vessel wall, less stimulation to the blood vessel, and can effectively protect the blood vessel; the indwelling time is longer, and it can be used for intravenous treatment at any time. However, with the development of a large number of various testing items in the clinic, it is necessary to collect venous blood from patients at any time. Due to the distance between the heparin cap and the blood vessel in the existing venous indwelling needle, blood sampling is not easy to succeed, and the tube lock solution has a great influence on the accuracy of the testing items. Interference, and the inconvenient disinfection of the nozzle where the needle seat is pulled out can not be used for blood collection and other defects, so venous blood collection is often carried out from blood vessels other than the indwelling needle, which has repeated punctures, damage to blood vessels and surrounding tissues, and brings pain to the patient.

Utility model content

The purpose of the utility model is to provide an indwelling needle which can be used for venous blood collection while the patient uses the indwelling needle.

In order to achieve the above-mentioned purpose, the utility model adopts the structure: including Y-shaped seat and isolation puncture plug, there is a needle sleeve below the Y-shaped seat, above the Y-shaped seat are respectively long catheter connecting tube and puncture needle needle tube, and the isolation puncture plug is in the When the puncture needle is inserted into the needle tube, the isolation puncture plug is arranged at the mouth of the puncture needle insertion tube, and the top edge of the isolation puncture plug is provided with a reflexed brim to seal the edge of the needle tube opening.

The beneficial effect of the utility model is that since the improved puncture needle inlet tube mouth is changed from open to sealed, so that the nozzle is convenient for disinfection, blood can be collected directly from this place, because the place is close and straight to the blood vessel, and the operation is convenient. It is easy to succeed, and realizes that the patient retains the venous indwelling needle and can be used for venous blood collection at the same time, which reduces the pain caused by multiple punctures to the patient, and reduces the workload of the nursing staff. promotion and application value.

Description of drawings

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

Structural schematic diagram of the utility model

In the figure: 1. Needle sleeve, 2. Needle core, 3. Needle tube, 4. Isolation puncture plug, 5. Needle seat, 6. Brim, 7. End cap and heparin cap, 8. Long catheter, 9. Connection Tube, 10. Y-shaped seat.

Detailed ways

As shown in the figure, below the Y-shaped seat 10 is the needle sleeve 1, and above the Y-shaped seat are the connecting tube 9 of the long catheter 8 and the puncture needle tube 3, and the isolation puncture plug 4 is in the puncture needle tube 3, and the The isolated puncture plug 4 is arranged at the mouth of the puncture needle tube 3 , and the top edge of the isolated puncture plug 4 is provided with a reflexed brim 6 to seal the edge of the mouth of the needle tube 3 .

The method of use of the utility model: before use, the needle core 2 of the puncture needle is in the needle sleeve 1, and the needle seat 5 is close to the top of the isolated puncture plug 4. 5 Send the needle sleeve 1 into the vein, pull out the needle core 2, and discard it together with the needle holder 5, then connect the infusion solution to the end cap or the heparin cap 7, and enter the patient's vein through the Y-shaped seat 10. If blood collection is required, the mouth of the needle tube 3 can be sterilized at the top of the isolation puncture plug 4, and the blood collection needle can be passed through the isolation puncture plug 4 to obtain blood.

Claims (1)

1. the venous detaining needle that can take a blood sample, comprise Y shape seat (10) and isolate puncture plug (4), there is needle cannula (1) Y shape seat below, Y shape seat top is respectively long duct connection tube (9) and puncture needle needle-inserting tube (3), isolate puncture plug (4) in puncture needle needle-inserting tube (3), it is characterized in that: will isolate puncture plug (4) and be arranged on the interior mouth of pipe place of puncture needle needle-inserting tube (3), and in the top of isolating puncture plug (4) the opisthotonos the brim of a hat (6) will be set and be sealed into needle tubing (3) mouth of pipe edge.
