Description

A clinical multifunctional indwelling needle

technical field

The utility model belongs to the field of medical equipment, in particular to a clinical multifunctional indwelling needle.

Background technique

Venipuncture is the most commonly used and main nursing operation for clinical auxiliary diagnosis and treatment. In order to accurately diagnose and treat diseases, necessary laboratory tests must be carried out in order to accurately diagnose and treat diseases. These tests are inseparable from venous blood collection. The existing blood collection needles are steel The needles are easy to puncture the blood vessel and the needle slips out of the blood vessel. After blood collection, indwelling and infusion cannot be performed. With the existing indwelling needle for blood collection, the blood flow rate is slow and it is easy to coagulate on the tube wall to form a thrombus, resulting in lumen blockage, Hemolysis or coagulation of blood samples not only increases the workload, but also brings a lot of inconvenience to clinical work.

Contents of the invention

Aiming at the defects and deficiencies in the prior art, the purpose of this utility model is to provide a multifunctional indwelling needle for clinical use. The puncture needle integrates three functions of blood drawing, puncturing and indwelling, and can be applied to clinical use, especially suitable for children.

In order to achieve the above object, the technical scheme that the utility model takes is:

A clinical multifunctional indwelling needle, comprising an indwelling unit and a puncture blood collection unit, the indwelling unit includes a double-way indwelling needle holder, a soft needle and an infusion part, and the puncture blood collection unit includes a one-way puncture needle holder, a steel needle and a blood collection part;

A rubber sealing plug is set in one channel of the double-way indwelling needle seat. The steel needle passes through the rubber sealing plug and is coaxially socketed with the soft needle. The puncture needle seat is connected with the blood collection part for blood collection. It is connected with the infusion part for infusion.

The length of the steel needle is greater than that of the soft needle.

Specifically, the blood collection component includes a blood collection tube and a blood collection joint connected in sequence.

More specifically, the blood collection joint is covered with a cleaning cover, and the blood collection joint communicates with the vacuum blood collection tube in the cleaning cover for blood collection.

Specifically, the infusion component includes an infusion tube and a two-way joint connected in sequence.

More specifically, the two-way joint includes a heparin cap and an infusion interface.

In addition, a protective cap is provided outside the soft needle.

The utility model has the advantages of:

(1) A clinical multifunctional indwelling needle of the present utility model, comprising an indwelling unit and a puncture blood collection unit, a rubber sealing plug is arranged in a channel of a double-way indwelling needle seat, and the steel needle passes through the rubber sealing plug and the soft needle The shaft is socketed, the puncture needle seat is connected with the blood collection part for blood collection, the other channel of the double-way indwelling needle seat is connected with the infusion part for infusion, and the original puncture and indwelling infusion function of the indwelling needle is expanded to collect indwelling, puncture infusion and The integrated part of blood collection greatly reduces the number of punctures for patients and reduces the workload of medical staff;

(2) The clinical multifunctional indwelling needle of the present utility model uses steel needles for blood collection, and the steel needles, blood collection tubes and blood collection joints after blood collection are directly discarded, which ensures the cleanliness of blood samples without affecting the indwelling , and the blood sample will not pollute the indwelling tube, avoiding the blockage of the indwelling needle by blood coagulation, and ensuring the quality of the blood sample before analysis.

The utility model is described in detail below in conjunction with the accompanying drawings and specific embodiments.

detailed description

1, 2 and 3, the clinical multifunctional indwelling needle of the present invention includes an indwelling unit 1 and a puncture and blood collection unit 2. The indwelling unit 1 includes a double-way indwelling needle holder 11, a soft needle 111 and infusion components, and the puncture and blood collection unit 2. It includes a one-way puncture needle base 21, a steel needle 210 and blood collection components; a rubber sealing plug 112 is set in one channel of the two-way indwelling needle base 11, and the steel needle 210 passes through the rubber sealing plug 112 and is coaxially socketed with the soft needle 111 , the puncture needle seat 21 communicates with the blood collection part for blood collection, and the other channel of the double-way indwelling needle seat 11 communicates with the infusion part for infusion, expanding the original puncture and indwelling infusion function of the indwelling needle to collect indwelling, puncture infusion and blood collection The integrated parts greatly reduce the number of punctures for patients and reduce the workload of medical staff;
