Description

Anti-stab blood collection needle

technical field

The utility model relates to a blood collection needle, in particular to a stab-proof blood collection needle.

Background technique

Occupational hazards are occupational injuries caused by improper self-protection during the work process, which leads to occupation-related diseases. With the improvement of people's living standards and health awareness, and the in-depth development of hospital inspection work, the workload of medical staff is increasing, and they have contact with various types of people every day. Due to the special nature of their work, they are often exposed to various Among the existing or potential risk factors, it is easy to become a high-risk group of occupational hazards. According to relevant domestic and foreign studies, the incidence rate of blood-related occupational exposure of blood collection personnel is 80.6% to 93.3% in China, and 52.0% to 89% in foreign countries. HCV, HIV, Tp and other virus carriers account for a certain proportion of the Chinese social population, and medical staff will be accidentally splashed with blood or stabbed by needles during the blood collection process, and medical staff have a high degree of infection Danger.

Needlestick injury is the most common occupational injury of medical personnel. It is an accidental injury deep enough in the skin to cause the victim to bleed, and the contaminated blood or body fluid will be inoculated into the injured person's body. According to the report of the World Health Organization, the possibility of acquiring HIV after being injured by a needle used by an HIV-positive patient is 0.2% to 0.4%; The probability is 0.2% to 6.0%. In addition, according to a study, as many as 94% of medical staff have been stabbed by sharp objects.

There are mainly the following reasons for the occurrence of acupuncture: 1. Putting used needles or other sharp instruments in places where they should not be placed or passing them around at will; 2. Putting used sharp needles or other sharp instruments into the overfilled sharps When the sharps box is tightly sealed, the operator is stabbed; 3. Insufficient awareness of the serious consequences of needlestick injuries, lack of attention to self-protection, and no great attention to needlestick injuries; 4. When puncturing , Injured by the needle due to excessive tension; 5. Injured by the needle because the patient did not cooperate during the puncture.

With the strengthening of medical care awareness, safe blood collection has been paid attention to by medical staff and patients, and various blood collection needles have been designed, such as the blood collection needle described in the Chinese utility patent CN201120242080.3, which uses a front protective cover and The back protective cover protects the needle of the blood collection needle. During operation, the front protective cover needs to be removed, which will expose the needle of the blood collection needle to the air, which is easy to accidentally injure the medical staff. After blood collection, hold the handle of the blood collection needle The needle is retracted into the rear protective sleeve, which makes the operation process complicated, which easily leads to fatigue and mistakes of the medical staff.

Therefore, need a kind of simple in structure at present, easy to operate, can avoid the lancet of lancet needle to injure medical staff and patient, to protect the personal safety of medical staff and patient.

Utility model content

The purpose of the utility model is to overcome the disadvantages of the prior art and provide a blood collection needle with simple structure, convenient operation and anti-stab injury.

The purpose of this utility model is achieved through the following technical solutions: a stab-proof blood collection needle, which includes a blood collection needle head, a needle handle and a flexible tube connected in sequence, the front end of the needle handle is connected with the rear end of the blood collection needle head, and the rear end of the needle handle The end of the blood collection needle is connected with one end of the flexible pipe. A sleeve is set on the outside of the needle of the blood collection needle. A movable groove is opened on the side of the sleeve. The needle handle is arranged in the movable groove. A groove is opened on the edge, the needle handle is stuck in the groove of the lower baffle, and an upper baffle is installed on the upper end of the movable groove.

It also includes a test tube needle and a protective cover, the other end of the flexible pipe is connected with the rear end of the test tube needle, and the protective cover is set on the outside of the test tube needle. The groove provided by the lower baffle plate is a square groove.

The sleeve is cylindrical with upper and lower openings, and the inner diameter of the sleeve is larger than the outer diameter of the blood collection needle.

The groove opened by the lower baffle is a square groove.

The width of the groove opened by the lower baffle is greater than the diameter of the needle head of the blood collection needle.

The utility model has the following advantages: the blood collection needle of the utility model ensures that no needle is exposed during the blood collection process. Before the needle is inserted, it prevents the needle body from being polluted by bacteria and viruses in the air; at the same time, it reduces the harm of the residual blood of the needle body exposed to the air after the needle is pulled out. The anti-stab blood collection needle can effectively reduce the probability of medical personnel being stabbed by a needle during the blood collection process, thereby reducing occupational hazards. Since the needle body of the blood collection needle is always in a protected state, it is prevented that the used blood collection needle is placed in a place where it should not be placed or passed around at will, which may cause harm to the operator. The used blood collection needle is in the sharps bucket, and the needle body is also in a protective covering state to prevent the operator from being stabbed when the personnel closes, handles, or overturns the sharps bucket. Moreover, the anti-stab blood collection needle has a simple structure and a delicate design, and is suitable for clinical popularization and operation.
