Problems solved by technology

[0007] For this reason, the technical problem to be solved by the present invention is that the safety protective cover in the prior art cannot be used universally, which is not conducive to mass production, and is easy to rotate during the use of the needle tube to interfere with the sight of the medical staff. The blood collection needle protective cover that does not rotate during the use of the needle tube; at the same time, a multi-tube blood collection device with the blood collection needle protective cover is further provided

Embodiment Construction

[0045] In the following, the present invention will be further described by using the following embodiments in conjunction with the accompanying drawings.

[0046] Such as Figure 1-7 As shown, a blood collection needle protective cover 3 described in this embodiment includes a needle base 2 provided with a needle head 1, and a protective cover 3 that is rotatably connected to the needle base 2 through a first connection structure. The protective cover 3 can rotate between the initial position and the storage position, and when the protective cover 3 is rotated to the storage position, the needle 1 can be snapped into the storage cavity 4;

[0047] The first connecting structure includes a connecting post 5 formed on the needle base 2, and a connecting hole 6 formed on the connecting end of the protective cover 3 that can be rotatably engaged with the connecting post 5;

[0048] It also includes a locking structure that can lock the protective cover 3 at the initial position,...

Abstract

The invention discloses a blood sampling needle protective sleeve which comprises a needle base provided with a needle base and a protective sleeve rotatably connected with the needle base by virtue of a first connecting structure, wherein the first connecting structure comprises a connecting convex column molded at the needle base and a connecting hole formed in the connecting end of the protective sleeve, and the connecting hole is rotatably buckled with the connecting convex column; the blood sampling needle protective sleeve further comprises a locking structure capable of locking the protective sleeve at an initial position; the locking structure comprises a lateral wing and a clamping slot, the lateral ring is molded at the needle base and radially extends, and the clamping slot is formed in the side wall of one side, adjacent to the lateral ring, of the protective sleeve and can be buckled with the lateral ring at the initial position. According to the blood sampling needle protective sleeve, the protective sleeve can be connected with any needle base by virtue of the first connecting structure, so that the protective sleeve has commonality and can be produced in batches; the locking structure can be used for locking the protective sleeve at the initial position, so that the protective sleeve is prevented from rotating randomly, further influencing the visual lines of medical care personnel and reducing the working efficiency in a needle head use process.

Description

technical field [0001] The invention relates to a medical injection needle device, in particular to a protective cover for a blood collection needle and a multi-tube blood collection device with the protective cover for the blood collection needle. Background technique [0002] In the work of blood bank or hematology, it is often necessary to collect blood samples for laboratory examination. Due to the different quantities of blood samples required for laboratory testing, it is often necessary to collect multiple tubes of blood samples at one time. Existing blood collection needles all have a single-tube structure. After the blood vessel is punctured, the vacuum blood collection tube can only be continuously replaced for blood collection. The blood collection takes a long time and causes great pain. Simultaneously, the lancet with a single-tube structure is used in a single way and cannot be applied to more occasions. [0003] For this reason, Chinese patent document CN202...
