Description

Technical Field

[0001] The utility model relates to the technical field of disinfection, in particular to a new type of punch-free needle. Background Art

[0002] Conventional wound disinfection and flushing, such as flushing pressure external wounds, requires multiple syringes to draw sterile liquids and then flush the wounds. On the one hand, it increases the chance of infection. On the other hand, it increases the risk of needle injuries for nurses. At the same time, multiple liquid extractions also increase the operating time of nurses. For busy clinical work, time is life, which is not conducive to the routine operation of nurses.

[0003] Therefore, we propose a new type of punch-free needle to solve the above problems. Utility Model Content

[0004] The utility model aims to solve the shortcomings of the prior art and provides a new type of punch-free needle.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A novel punch-free needle comprises a needle tube, a ferrule and a clamp. The ferrule is in a circular ring shape. The needle tube is inserted in the ferrule. The tip of the needle tube is provided with a plurality of liquid outlets. The end of the needle tube is provided with a liquid inlet. The plurality of liquid outlets are connected to the liquid inlet. The clamp is provided with a plurality of clips. The clips are in a curved trumpet arc shape. The end of the clips contracts inwardly to form a hook shape. The plurality of clips are fixedly connected to the lower end of the ferrule.

[0007] Preferably, both ends of the needle tube are expanded, and the middle part is in a contracted arc shape.

[0008] Preferably, the card clip is made of plastic, and a metal strip is embedded inside the card clip.

[0009] Preferably, a plurality of recessed notches are provided at the edge of the portion where the clamp is connected to the sleeve.

[0010] Preferably, a film layer is attached to the exterior of the card clip.

[0011] Preferably, the length of the clip is shorter than the needle tube.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. By cooperating with the needle tube, the clamp and the metal strip, the elastic effect of the clamp and the metal strip is utilized, so that the clamp can be fixedly inserted into the bottle mouth of the disinfectant with the needle tube, and then the disinfection and flushing operation is performed. The clamp also wraps the needle tube, thereby improving the operating efficiency and reducing the risk of needlestick for nurses.

[0014] 2. By cooperating with the set notches and the film layer, when the needle needs to be taken out, the notches can be used to press the clip to force it to break at the notches, causing it to lose its elasticity, so that the needle can be pulled out again. At the same time, after the clip is broken, the film layer can maintain the connection to prevent it from falling. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0020] Conventional wound disinfection and flushing, such as flushing pressure external wounds, requires multiple syringes to draw sterile liquids and then flush the wounds, which increases the chance of infection. On the one hand, it increases the risk of needle injuries for nurses. At the same time, multiple liquid extractions also increase the operating time of nurses. For busy clinical work, time is life, which is not conducive to routine operation of nurses. Therefore, refer to Figure 1-3 The present invention designs a novel punch-free needle, comprising a needle tube 1, a ferrule 2, and a clamp 3. The ferrule 2 is in a circular ring shape and is used to sheath and limit the needle tube 1. The needle tube 1 is inserted into the ferrule 2 for use. In order to prevent the needle tube 1 from escaping from the ferrule 2, the ends of the needle tube 1 are enlarged and the middle part is in a contracted arc shape. The middle part of the needle tube 1 can be normally drawn in the ferrule 2. Since the two ends are enlarged structures, the needle tube 1 will not escaping from the ferrule 2. When in use, the needle tube 1 can be directly inserted into the disinfection bottle.

[0021] At the same time, the tip of the needle tube 1 is provided with a plurality of liquid outlet holes 8, and the end of the needle tube 1 is provided with a liquid inlet hole 4. The plurality of liquid outlet holes 8 are connected to the liquid inlet hole 4. After the needle tube 1 is inserted into the disinfection bottle, the disinfectant is directly discharged through the liquid outlet hole 8 and the liquid inlet hole 4 to achieve the effect of direct flushing. In order to enable the needle tube 1 to output effectively, a plurality of clips 3 are provided. The function of the clips 3 is to be fixed at the bottle mouth of the disinfection bottle. The length of the clips 3 is shorter than the needle tube 1 to prevent affecting the normal use of the needle tube 1. After insertion, the disinfection and cleaning operations can be carried out continuously, whether it is normal disinfection or emergency use in the field.

[0022] The clip 3 is in the shape of a curved trumpet arc, and the end of the clip 3 is retracted inwardly to form a hook shape. Multiple clips 3 are fixedly connected to the lower end of the sleeve 2. The clip 3 is made of plastic, and a metal strip 5 is embedded in the interior of the clip 3. Therefore, the clip 3 can be directly clamped at the bottle mouth of the disinfection bottle. When it needs to be pulled out, since multiple recessed notches 6 are provided at the edge of the portion where the clip 3 is connected to the sleeve 2, and a film layer 7 is attached to the outside of the clip 3, the clip 3 is pressed to break at the notch 6, causing it to lose its elastic effect, thereby pulling out the needle tube 1 again. After the clip 3 is broken, the film layer 7 is used to maintain the connection to prevent it from falling.

[0023] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
