Description

A venous blood collection needle with a protective cap

Technical field

The utility model relates to the technical field of medical equipment, in particular to a venous blood collection needle with a protective cap.

Background technique

A venous blood collection needle is a blood collection needle used to collect blood samples during medical examinations. It is usually divided into two ends. One end is a thimble that is inserted into the patient's body to draw blood, and the other end is used to pierce the vacuum blood collection test tube. Using the test tube The negative pressure inside draws blood into the tube;

For example, the publication number is CN213249108U, which is a utility model patent titled "A Blood Glucose Measurement Blood Collection Needle Kit for Internal Medicine Nursing", which includes a blood collection needle. One end of the blood collection needle is fixedly installed with a metal needle, and a needle holder is connected to the blood collection needle. A rubber hose is fixedly installed at one end away from the metal needle, a puncture needle is fixedly installed at one end of the rubber hose away from the blood collection needle, and a puncture needle is provided at one end away from the rubber hose, and the puncture needle is made of conventional plastic. A connecting device is provided between the needle and the puncture needle. The puncture needle in this utility model is made of conventional plastic, and the end of the puncture needle away from the rubber hose is pointed. The use cost is low and the puncture needle can be easily inserted into the vacuum blood collection tube. There is a set of holes between the blood collection needle and the puncture needle. The connection device, after connecting the blood collection needle and the puncture needle, can prevent the tips of the blood collection needle and the puncture needle from being directly exposed, thereby preventing the blood collection needle and the puncture needle from puncturing the plastic bag packaging, with reasonable design and good practical effect;

When the blood collection needle is finished using, it often needs to be capped. Some existing blood collection needles are as shown in the above-mentioned patents. The needle tip and the needle cap are designed to be separated. When used, the needle cap is removed, and during the capping process , the opening of the needle cap needs to be aligned with the thimble of the blood collection needle. Since the thimble of the blood collection needle is relatively small, and the opening of the needle cap is also small, it is easy to misalign when operating quickly during busy hours, causing the needle tip to slide on the side of the needle cap. This can injure medical staff and cause blood-borne transmission of some diseases.

In order to achieve the above purpose, the present utility model provides the following technical solution: a venous blood collection needle with a protective cap, including a cover and a needle body installed in the cover. A sliding rod is slidably installed on the needle body. A connecting plate is fixedly installed on the rod, and a rotating rod is rotatably installed on the connecting plate. An outer plate is fixedly installed on the rotating rod, and a protective cover is fixedly installed on one end of the outer plate close to the housing.

Preferably, a sponge is fixedly installed on the inner wall of the protective cover.

Preferably, two positioning blocks are fixedly installed on the connecting plate, and side blocks are fixedly installed on the rotating rod.

Preferably, a connecting portion is fixedly mounted on the needle body, and the connecting portion is threadedly connected to the housing.

Preferably, the connecting portion is provided with a groove.

Preferably, the connecting portion is provided with a chute that matches the size of the sliding rod, and the sliding rod has a T-shaped cross-section.

In the above technical solution, the present invention provides a venous blood collection needle with a protective cap, which has the following beneficial effects: when the blood collection needle is in use, the protective cover is rotated to one side of the housing, and when the blood collection needle is finished using Finally, rotate the outer plate. At this time, the outer plate will drive the protective cover to rotate to the top of the casing to align with the exposed needle body. Then press the outer plate toward the casing, so that the outer plate will drive the protective cover to move the exposed needle body. At this time, the operation of the protective cover is done on the side of the exposed needle body, which avoids the traditional problem that when the syringe is wrapped around the needle, it is easy to skew and cause the needle to be inserted into the hands of medical staff.

Detailed ways

In order to enable those skilled in the art to better understand the technical solution of the present utility model, the present utility model will be introduced in further detail below with reference to the accompanying drawings.

Please refer to Figures 1-5, a kind of venous blood collection needle with a protective cap. In the technical solution proposed by the utility model, it includes a cover 1 and a needle body 2 installed in the cover 1. The needle body 2 is slidably mounted with a slider. The connecting plate 32 is fixedly installed on the rod 31 and the sliding rod 31. The rotating rod 33 is rotatably installed on the connecting plate 32. The outer plate 34 is fixedly installed on the rotating rod 33. An end of the outer plate 34 close to the housing 1 is fixedly installed with a protective cover. 35; When the blood collection needle is in use, rotate the protective cover 35 to one side of the housing 1. After the blood collection needle is used, rotate the outer plate 34. At this time, the outer plate 34 will drive the protective cover 35 to rotate to the housing. 1, so as to be aligned with the exposed needle body 2, and then press the outer plate 34 towards the direction of the sleeve 1, so that the outer plate 34 drives the protective cover 35 to cover the exposed needle body 2. At this time, the protective cover 35 The operations are all performed on the side of the exposed needle body 2, which avoids the traditional problem of the needle being easily skewed when the syringe is wrapped around the needle, causing the needle to be inserted into the hand of the medical staff.

Specifically, a sponge is fixedly installed on the inner wall of the protective cover 35; after the protective cover 35 is covered on the needle body 2 through the sponge, the sponge can absorb the blood remaining in the needle body 2 to prevent the blood from spilling when the needle body 2 moves.

Specifically, two positioning blocks 321 are fixedly installed on the connecting plate 32, and side blocks 331 are fixedly installed on the rotating rod 33; the two positioning blocks 321 are respectively located on both sides of the connecting plate 32 and both face outward from the connecting plate 32. The direction of the plate 34 extends. When the outer plate 34 is rotated, the outer plate 34 will drive the rotating rod 33 to rotate. At this time, the side blocks 331 on the rotating rod 33 will rotate synchronously until the side blocks 331 rotate to the position above the connecting plate 32 After the block 321 is in contact, the protective cover 35 is in a vertical state. When the outer plate 34 is rotated close to the lower positioning block 321, the protective cover 35 will be located on one side of the casing 1, and the outer plate 34 When it abuts on the lower positioning block 321 and cannot rotate anymore, the outer plate 34 can be used as a handle to facilitate screwing the connecting part 21 into the housing 1 .
