Description

Ear lobe puncture needle

Technical Field

The utility model relates to a medical needle utensil field especially relates to an earlobe pjncture needle.

Background

Bedside blood glucose monitoring often collects the capillary sites at the distal ends of the fingers. Specifically, a puncture needle is used for puncturing a puncture part, and blood is collected by blood glucose test paper for detection.

In special cases, such as critically ill patients, edema of the limbs, collapse of blood vessels in the fingers, ulceration or during double-sided arm infusion, blood is often collected from the ear lobes for blood glucose measurement. Due to the limitation of tissue thickness, the needle insertion direction of the earlobe is from the periphery of the earlobe to the vertical direction of the center of the earlobe during blood collection. However, when the blood in the earlobe is collected in this way, the earlobe is thin, and the puncture needle is easy to pierce through the earlobe and pierce the fingers of the nurse, so that occupational exposure is caused.

This is sometimes the case in hospitals, and is described in "Nurse of contemporary" No. 2019, Vol.4, No. 26, No. 10 "1 clinical thinking about adverse events of needle stick injury caused by measuring blood sugar level via earlobe".

Drawings

FIG. 1 is a block diagram of an earlobe puncture needle;

FIG. 2 is a view showing a state of use of the earlobe puncture needle;

labeled as: the device comprises a U-shaped clamp 1, a needle connecting plate 11, an earlobe pad 12, a puncture structure 2, a guide rod 21, a needle body 22, an elastic piece 3, a needle cap 4, a sleeve 41, a handle rod 42 and an earlobe 5.

Detailed Description

The present invention will be further described with reference to the accompanying drawings and the following detailed description.

As shown in fig. 1, the earlobe puncture needle comprises a U-shaped clip 1, a puncture structure 2 and an elastic member 3, wherein one side plate of the U-shaped clip 1 is a needle connecting plate 11, the other side plate of the U-shaped clip 1 is an earlobe backing plate 12, the puncture structure 2 is perpendicular to the needle connecting plate 11, the puncture structure 2 comprises a guide rod 21 and a needle body 22, the guide rod 21 is inserted into the needle connecting plate 11 and is matched with the needle connecting plate 11, the elastic member 3 outwards supports the guide rod 21, and the needle body 22 is connected to the inner end of the guide rod 21; the needle body 22 can be moved forward to perform puncture by pressing the guide bar 21.

As shown in fig. 2, when the utility model is used, the hand-held U-shaped clip 1 is sleeved on the earlobe 5; then one finger of the hand holds the earlobe pad 12, the other finger presses the guide rod 21, the needle body 22 moves forwards to puncture the earlobe 5, and the elastic part 3 deforms correspondingly; then the fingers are released, the elastic part 3 rebounds, the needle body 22 moves backwards and exits the ear lobe 5, and the puncture of the ear lobe 5 is completed. In the above process, the earlobe pad 12 is placed on the earlobe 5, and even if the needle body 22 pierces the earlobe 5, only the earlobe pad 12 can be pierced without piercing the nurse.

When the guide bar 21 is pressed, the needle web 11 is exposed into the U-shaped clamp 1, so that the puncture is only possible. When the guide bar 21 is not pressed, if the needle body 22 is exposed from the needle connecting plate 11, the needle body 22 may damage the earlobe 5 during the process of putting the hand-held U-shaped clip 1 on the earlobe 5. The needle connecting plate 11 and the earlobe backing plate 12 of the utility model have shielding effect on the needle body 22, so that the probability of needle stick injury is low, but not impossible. For the above reasons, the preferred needle body 22 of the present invention is located in the needle connecting plate 11. Therefore, the ear lobe 5 can be prevented from being damaged by the needle body 22 in the process that the U-shaped clamp 1 is sleeved on the ear lobe 5, and the ear lobe puncture needle can be prevented from being injured by the needle before and after use.

The specific arrangement mode of elastic component 3 can have the multiple, the utility model discloses preferred mode as follows: the elastic part 3 is a spring, the elastic part 3 is positioned in the needle connecting plate 11 and sleeved outside the guide rod 21, the inner end of the elastic part 3 is abutted against the needle connecting plate 11, and the outer end of the elastic part 3 is abutted against the guide rod 21.

During the process of putting the U-shaped clip 1 on the ear lobe 5, the hand should not press the guide bar 21 to prevent the needle body 22 from moving forward. After the U-shaped clamp 1 is placed on the ear lobe 5, the finger holder holding the earlobe pad 12 is moved onto the guide bar 21 and pressed onto the guide bar 21, during which the separation of the finger from the earlobe pad 12 may cause the earlobe puncture needle to move away from the ear lobe 5 and even fall off. In order to avoid this problem, the present invention preferably has a spherical outer surface shape of the needle attachment plate 11, a spherical outer surface shape of the guide rod 21, and a smooth transition between the outer surface of the needle attachment plate 11 and the outer surface of the guide rod 21. In this way, during the above operation, the finger can be slipped from the earlobe pad 12 onto the guide rod 21 without the finger leaving the earlobe puncture needle, preventing the earlobe puncture needle from being removed from the earlobe 5 and falling off.

In order to avoid contamination of the needle body 22 before the earlobe puncture needle is used, it is preferable that the earlobe puncture needle comprises a needle cap 4, the needle cap 4 comprises a cannula 41 and a handle bar 42, the cannula 41 is sleeved on the needle body 22, the handle bar 42 is connected with the cannula 41, and the handle bar 42 exposes the U-shaped clip 1. The cannula 41 is used to prevent contamination of the needle body 22 and the handle post 42 is used to facilitate handling of the needle cap 4 for insertion and removal of the needle cap 4.
