Description

IV needle

technical field

The utility model relates to the field of medical equipment, in particular to an intravenous infusion needle.

Background technique

At present, a large number of infusion needles used in China are simply covered with a protective cover on the metal needle. When puncturing, the protective cover is removed. After the injection, the protective cover is not put back on the needle, so the metal needle is exposed after injection. On the outside, the role of this protective sleeve is to protect the metal needle from bacteria when it is not in use, not to puncture it. When using an infusion needle for infusion, after the infusion is completed, the needle is pulled out of the infusion needle, and the needle is exposed, and the nurse has the risk of being stabbed by the needle. Therefore, in the whole process of using the infusion needle for infusion, the incident of the nurse being stabbed occurs from time to time. Therefore, the existing infusion needles have potential safety hazards, and the society is in urgent need of a protective infusion needle that can reduce potential safety hazards.

detailed description

The utility model is introduced in detail below in conjunction with specific methods.

Referring to FIG. 1 , the utility model proposes an intravenous infusion needle, including a needle head 1 , a needle holder 2 , an infusion hose 3 sleeved on the rear end of the needle holder 2 , and a protective sheath 4 connected in sequence. The side of the needle base 2 is provided with a needle handle 21, and the protective cover 4 is tubular; on the side wall of the protective cover 4, a slit 41 is provided in the axial direction from the base; the length of the slit 41 is less than the length of the protective cover 4; The slit 41 is wave-shaped; the protective sheath 4 slides back and forth along the needle head 1 and the needle handle 21 through the slit 41 .

The structure of the intravenous infusion needle of the utility model is very simple. Before the infusion needle is used, its protective sheath 4 is set on the needle, so that the slit 41 at the base of the protective sheath 4 is just clipped on the needle handle 21, so that the protective sheath 4 can be prevented from slipping off, preventing it from stabbing the medical personnel. Because the length of the slit 41 is less than the length of the protective cover 4, that is to say, the slit 41 does not penetrate the entire tubular protective cover 4, and the upper part of the slit 41 has a seal. When the patient is punctured with an infusion needle, the protective cover 4 can be directly The infusion hose is pulled in the direction until the seal stops at the front end of the needle handle 21, and then the patient is punctured. Due to the existence of the seal, the protective cover 4 will not be separated from the needle handle, preventing it from sliding onto the infusion tube as a whole; when the infusion is completed, the protective cover 4 can be directly pulled toward the needle tip to protect the used needle from 1 pierce the paramedic and place it directly into the sharps bucket. In addition, the slit 41 of the utility model is wave-shaped, and when the protective cover 4 slides back and forth along the needle head 1 and the needle handle 21 through the slit 41, the medical staff can save more effort when pulling the protective cover 4 forward and backward.

The protective sheath in this embodiment is in the shape of a cylinder as a whole, and of course it can also be in other shapes such as a diamond tube or a rectangular tube.

Because the needle head 1 length of the infusion needle that uses now is generally about 2.5cm, so the length of protective cover 4 is 3-4cm, preferably, the length of described protective cover 4 is 3.5cm, can wrap up needle head on the one hand, another On the one hand, the other end of the protective sleeve can be put on the needle seat to prevent it from slipping off. Since the diameter of the front end of the needle holder is generally about 2 mm, in order to facilitate the protective cover 4 to be placed on it, the tube diameter of the protective cover 4 in this embodiment is 3-5 mm, preferably, the tube diameter is 3.5 mm or 4 mm; the slit The length of 41 is 2.5-3.5cm; The length of slit 41 is 3cm.

Since the base of the protective sheath 4 is fitted on the needle hub 2 before use, the inner wall of the protective sheath 4 is provided with axial anti-slip lines in order to prevent the protective sheath 4 from slipping off. In addition, in order to further prevent the protective sheath 4 from slipping, a clamping strip is provided at both ends of the slit 41 at the base of the protective sheath 4 , and the needle handle 21 is provided with a clamping groove 211 on both sides of the front and back of the needle handle 42 to cooperate with the clamping strip 42 .

In order to facilitate the medical staff to move the protective cover 4, the outer wall of the protective cover 4 in this embodiment is provided with a side wing 44 for pushing the protective cover 4 to slide back and forth; the side wing 44 is provided with anti-slip lines 441, which is convenient for the staff to apply force. In addition, the material of this protective case and side wings is PVC.

The above embodiments are only used to illustrate the technical solutions of the present utility model, and are not intended to limit it; although the utility model has been described in detail with reference to the foregoing embodiments, for those of ordinary skill in the art, the aforementioned implementation can still be carried out. The technical solutions described in the examples are modified, or some of the technical features are equivalently replaced; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions claimed by the utility model.
