Venous blood taking needle

Abstract

A vein puncture needle is arranged at one end of a needle seat, a bottle inserting end puncture needle is arranged at the other end of the needle seat, a needle tip of the bottle inserting end puncture needle is bent towards the axis direction of the needle tip, a rubber sleeve is sleeved outside the bottle inserting end puncture needle, and a vein puncture needle cap is sleeved outside the vein puncture needle. And an intubation needle cap is sleeved outside the bottle-inserting end puncture needle and the rubber sleeve. The puncture needle has the advantages that the protective rubber sleeve is independently arranged outside the puncture needle at the bottle inserting end, the protective caps are independently arranged outside the vein puncture needle and the puncture needle at the bottle inserting end, the protective caps are used for protecting the sterilized and disinfected double-end needle tube from being polluted, the needle point of the puncture needle at the bottle inserting end is designed to be of an inwards-bent structure, and the puncture needle is convenient to use. In the puncture process of the bottle inserting end, the needle point of the puncture needle at the bottle inserting end can be prevented from penetrating out of the side face of the rubber sleeve to cause blood leakage.

Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of medical instruments, in particular to its mechanical connection structure. BACKGROUND

[0002] The prior art document 1, patent number: CN201320043289.6, application date: January 27, 2013, patentee: Qingdao Municipal Hospital, the case discloses a sticking type anti-puncture venous blood taking needle, including the needle tube with needle handle of the needle head and the needle head lower end, characterized in that the needle handle is provided with adhesive stickers, and the needle tube is provided with a needle head protective sleeve.

[0003] The prior art document 2, patent number: CN202022438082.1, application date: October 28, 2020, patentee: Shenzhen People's Hospital, the case discloses an improved blood taking needle, which comprises a blood taking needle fixed at one end of a blood taking needle rod, a tail needle fixed at one end of a tail needle rod and an extension tube connected between the blood taking needle rod and the tail needle rod.

[0004] The existing blood taking needle venipuncture needle and bottle insertion end puncture needle do not have a separate protection structure, which can easily lead to needle contamination, so further improvement of the prior art is still needed. SUMMARY

[0005] The utility model discloses a venous blood taking needle, which separately sets a protective rubber sleeve outside the bottle insertion end puncture needle, and also separately sets a cap outside the venipuncture needle and the bottle insertion end puncture needle, to protect the double-head needle tube after sterilization and disinfection from being contaminated, overcoming the shortcomings and deficiencies in the prior art.

[0006] In order to achieve the above-mentioned purpose, the technical scheme of the utility model is as follows: a needle holder is provided, one end of the needle holder is provided with a venipuncture needle, the other end of the needle holder is provided with a bottle insertion end puncture needle, the needle tip of the bottle insertion end puncture needle is bent towards the axial direction, a rubber sleeve is sleeved outside the bottle insertion end puncture needle, a venipuncture needle cap is sleeved outside the venipuncture needle, and a cannula needle cap is sleeved outside the bottle insertion end puncture needle and the rubber sleeve.

[0007] The utility model discloses a venous blood taking needle has beneficial effects: the product has separately arranged a protective rubber sleeve outside the bottle end puncture needle, and still has separately arranged a cap outside the venous puncture needle and bottle end puncture needle, is used for protecting the double-end needle tube that has been sterilized and disinfected after will not be contaminated, and the needle point of bottle end puncture needle is designed to the structure of inward bending, can avoid the needle point of bottle end puncture needle from the rubber sleeve side to wear out in the bottle end puncture process, leads to blood leakage.

[0011] The utility model is further described below with reference to the drawings.

[0012] The utility model discloses a venous blood taking needle, which is distinguished from the prior art in that: a needle seat 1 is provided, one end of the needle seat 1 is provided with a venous puncture needle 21, the other end of the needle seat 1 is provided with a bottle end puncture needle 22, the needle tip of the bottle end puncture needle 22 is bent towards the axial direction thereof, a rubber sleeve 4 is sleeved outside the bottle end puncture needle 22, a venous puncture needle cap 3 is sleeved outside the venous puncture needle 21, and a cannula needle cap 5 is sleeved outside the bottle end puncture needle 22 and the rubber sleeve 4.

[0013] In specific implementation, the outer wall of the needle seat 1 is provided with external threads 6, which can be used in conjunction with a needle holder, and the needle holder is a prior art that will not be described further.

[0014] The above content is a further detailed description of the utility model in combination with a specific preferred embodiment, and cannot be regarded as limiting the specific implementation of the utility model to the above description. For ordinary skilled persons in the technical field to which the utility model belongs, without departing from the concept of the utility model, a number of simple deductions or substitutions can be made, which should all be regarded as falling within the protection scope of the utility model.
