Description

Disposable sterile acupuncture needles

technical field

The utility model relates to a medical device, in particular to an acupuncture needle meeting the aseptic technical requirements.

Background technique

Acupuncture is a medical technique that originated in China and has been used in China for more than 2,500 years. Today, acupuncture is still widely used clinically as a simple and effective treatment method, and acupuncture fever has risen all over the world. Acupuncture needles are a commonly used medical device for acupuncture treatment. Acupuncture needles are composed of a needle body and a needle handle. For more than two thousand years, traditional Chinese medicine has been directly holding acupuncture needles with hands and inserting them into acupoints for treatment. Although the acupoints are disinfected before acupuncture treatment, the acupuncture needles used also require high-pressure steam sterilization or disposable sterile acupuncture needles. However, because the acupuncture needles are slender and soft, they often cannot penetrate the skin by only holding the needle handle. When performing acupuncture and moxibustion treatment, if you use longer acupuncture needles, that is, those with a needle body length of 40mm (1.5 inches) to 200mm (8 inches), it is difficult to pinch the handle of the acupuncture needle and insert the needle. to the needle body. The commonly used way of holding the needle is the pen-holding style, that is, the thumb and index finger of the pricking hand pinch the needle handle, and the pulp of the middle finger rests on the lower end of the needle body. Like this, because the acupuncture needle that pierces human tissue touches operator's hand and is polluted, does not accord with the principle of aseptic technique operation. Due to the increase in blood-borne disease infections, the number of iatrogenic infections is also on the rise. Improving acupuncture and moxibustion instruments and operating methods has become an urgent problem to be solved in hospital infection management. In this context, many people of insight continue to explore and invent new acupuncture instruments. As described in the Chinese patent document No. 200620061852.2, acupuncture needles are packaged with a sheath, and the sheath is torn to expose the needle tip during treatment. The sheath is kept outside the acupuncture needle to isolate the operator's hand from the acupuncture needle, and the operator holds the sheath and the needle body with his hand to operate, reducing the chance of the acupuncture needle being contaminated during operation. However, due to the sharp point of acupuncture needles, acupuncture needles are easy to pass through the sheath and be contaminated during production, packaging, transportation, storage, and use; The aseptic area of the puncture site causes secondary pollution; moreover, when the operator's hands sweat, the sweat soaking through the paper packaging sheath will also contaminate the acupuncture needles, so it is necessary to develop safer acupuncture needle devices.

Detailed ways

Below in conjunction with accompanying drawing, the utility model is described further, but not limited to embodiment.

Example 1

This embodiment is a disposable sterile acupuncture needle, which is composed of a needle handle 2, a needle body 1 and an acupuncture needle cover. The acupuncture needle cover is composed of a needle cover 3 and a needle point cap 4. 4 is made of hard material, the needle handle 3 and the needle point cap 4 are closely connected, the needle handle 2 and the needle body 1 of the acupuncture needle are put into the needle cover 3, the needle point cap 4 is put into the needle cover 3, and the packaging and sterilization are ready Can. The needle body is made of stainless steel wire, the needle handle is copper wire, and the outer layer is silver-plated, which is harmless to the body. The needle point cap can be made of hard plastic into a tubular shape; it can also be made of polymer material with a closed bottom and a conical shape at the connection with the needle cover. The inner diameter of the needle tip cap is larger than the diameter of the needle body of the acupuncture needle, and the diameter of the needle tip cap is 2.5-3 mm. Sockets are tubes of soft plastic or latex tubes. The top of the needle cover is closed, and the inner diameter of the needle cover is slightly greater than or equal to the outer diameter of the needle point cap, which is 3-3.5 mm, so that the needle point cap can be inserted into the needle socket and tightly combined. The inner diameter of the needle cover is 2-3 times the diameter of the needle handle of the acupuncture needle, which is convenient for the acupuncture needle cover to come off. Each acupuncture needle of the utility model is sheathed with a needle sheath and a needle point cap, and is individually packaged and sterilized at low temperature for clinical use.

In clinical use, you can directly pinch the needle sheath so that it is convenient to pinch the acupuncture needle in the sheath for operation; you can also use a general needle holder or a special needle holder for acupuncture needles to hold the acupuncture needle for operation.

The operation method of pinching the needle sheath and pinching the acupuncture needle in the sheath: After routinely disinfecting the skin and mucous membrane of the acupoint to be acupunctured, tear open the package, take out the acupuncture needle of the utility model, pinch the needle sheath with the right hand, and the acupuncture needle is facing upwards, so as to prevent the acupuncture needle from When it falls off, pinch the needle point cap with your left hand and pull out the needle point cap, pinch the needle cover and the acupuncture needles in the cover with your right hand to pierce the acupoint, gently lift and withdraw the needle cover, pinch the handle of the acupuncture needle, and continue to insert and perform acupuncture as needed During the acupuncture technique and needle retention, the operator's hands and pollutants should not touch the needle tip and body of the acupuncture needle during the whole process.

Operation method with a needle holder: After disinfecting the acupoints by the conventional method, tear open the package, take out the acupuncture needle of the utility model, pinch the needle cover with the right hand, with the acupuncture pointing up to prevent the acupuncture needle from falling off, pinch the needle point cap with the left hand and pull out the needle point cap, Use the needle holder to hold the needle tip of the acupuncture needle and pull out the acupuncture needle.
