Problems solved by technology

However, this structure has a disadvantage: the requirements for easy operation require the opening of the needle tip of the needle tube at the blood collection end and the needle tube at the collection end to be the same; Injection molding processing after accurate processing, which consumes a lot of manpower and material resources, seriously affects production efficiency
However, due to the sh

Embodiment Construction

[0033] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0034] Figure 1~4 A visible blood collection needle is shown, which includes a blood collection steel needle 1, a transparent steel needle holder 2 and a casing, the blood collection steel needle 1 includes a hollow needle tube, and the two ends of the needle tube are sharp ends, which are respectively the blood collection end 11 and the collection end 12. The opening direction of the needle tip of the blood collection end 11 and the collection end 12 of the blood collection steel needle 1 are the same.

[0035] The needle tip of the collection end of the blood collection needle is bent toward the center line of the blood collection needle, and the angle between the extension line of the needle tip and the center line of the blood collection needle is 15° to 30°;

[0036] The needle tip of the blood collection end is composed of sev...

Abstract

The invention discloses a visual blood collecting needle, comprising a blood collecting steel needle, a transparent steel needle fixing seat and a shell. The blood collecting steel needle comprises ahollow needle tube, two ends of the needle tube are tips, respectively a blood collecting end and a collecting end, and one or two slot-shaped visual openings are arranged along the surface of the steel needle in the long direction. The steel needle fixing seat is an integral structure arranged on the outside of the blood collecting steel needle, and comprises a cannula sleeved on the middle section of the steel needle, wherein the cannula surrounds a sealed cavity on the outside of the blood collecting steel needle; The outer side of the sleeve is a hollow conical protective shell. A manufacture method comprises that follow steps of: injection molding; Making of rubber protective sleeve; Manufacture of steel needle for blood sampling; Assemble. The present invention provides a visual blood collecting needle after assembly and sterilization. By improving the structure of the existing blood sampling needle, not only the chance of blood contamination can be reduced, but also the difficulty of processing can be greatly reduced, and the shortcoming of the prior art processing technology can be overcome.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an anti-pollution elbow blood collection needle and a manufacturing method. Background technique [0002] Vacuum blood collection technology has been widely used in clinical practice because of its accuracy, efficiency and safety. [0003] Existing vacuum blood collection tubes are generally split structures, including a blood collection end needle tube for puncturing the patient's skin, a collection end needle tube for puncturing the rubber stopper of the sealed blood collection tube, and the above-mentioned two needle tubes connected. Hose construction. In order to ensure that the needle tube is accurately inserted into the patient's blood vessel during operation, the flexible tube is usually a transparent structure. When blood flows into the flexible tube, the needle tube at the collecting end is inserted into the vacuum blood bottle, and the blood is sucked out of th...
