Abstract

The utility model discloses a kind of puncturing and lavage needle used in the paunch cavity, including a needle handle and a needle head. The features are: the needle handle has an empty cavity throughout the needle handle; the upper and lower end of the needle handle is provided with the openings; the openings are communicated with the empty cavity; the needle has a plurality of small holes; the needle head is a cone needle head; the needle handle is provided with an empty cavities inside and openings on both ends to combine the two devices of the puncturing needle of the paunch cavity and the set needle laid in the tube; when used, the single operation is not needed; the needle handle has a plurality of small holes; thus the drainage is relatively smooth and is not easy to be blocked; therefore the use is more convenient; and the device can prevent the extrication of the syringe nipple to lead the air into the paunch cavity; and the device is relatively safe.

Description

Abdominal paracentesis lavation pin

Technical field

This utility model relates to a kind of abdominal paracentesis lavation pin, belongs to medical instruments field.

Background technology

At present, abdominal dialysis, peritoneal lavage, cyst of kidney, the drain of diseases such as pyonephrosis, mainly be to take to operate on the method for the treatment of, minority adopts the abdominal paracentesis pin and puts two independent devices of pipe box pin, locate with lancet puncture earlier during drain, extract puncture needle then and will put of the direction puncture of pipe box pin again along puncture needle, to put the pipe box pin again and be connected with syringe nipple, offset direction when puncture easily is not easy the one-time puncture success so on the one hand, dangerous and can bring misery to the patient, when carrying out drainage procedure, be drawn out with syringe nipple and deviate from back air admission intraperitoneal for preventing to put the pipe box pin, often need two people to cooperate, use inconvenient, in addition, because intraperitoneal pus thickness also contains thickness compositions such as a large amount of protein, the pin hole of putting the pipe box pin stops up easily, uses inconvenient.

Summary of the invention

The purpose of this utility model provides the abdominal paracentesis lavation pin of a kind of convenience, safety.

For achieving the above object, the technical scheme that this utility model adopted is: abdominal paracentesis lavation pin, comprise needle handle, syringe needle, it is characterized in that: have the cavity that runs through needle handle in the described needle handle, described needle handle has opening respectively in two ends up and down, described opening is communicated with cavity, and described needle handle is provided with a plurality of apertures, and described syringe needle is the taper syringe needle.

Be this utility model technical scheme more specifically below:

The lower end of described needle handle is provided with switch.

The external diameter of described needle handle is that 4mm, internal diameter are that 3mm, length are 12cm.

Beneficial effect: this utility model adopts above technical scheme, be provided with cavity in the needle handle, the two ends of needle handle are provided with opening, and this device is with the abdominal paracentesis pin and put two kinds of devices of pipe box pin and combine, and do not need independent operation during use, needle handle is provided with a plurality of apertures, drain is more unobstructed, is difficult for stopping up, so use more convenient, also can avoid syringe nipple to deviate to cause the air admission abdominal cavity, relatively safety.

The utility model is described in further detail below in conjunction with drawings and Examples.

Description of drawings

Accompanying drawing is the structural representation of this utility model embodiment.

The specific embodiment

Specific embodiment, as shown in the figure, abdominal paracentesis lavation pin, comprise needle handle 1, syringe needle 2, has the cavity 3 that runs through needle handle 1 in the described needle handle 1, described needle handle has opening respectively in two ends about in the of 1, and described opening is communicated with cavity 3, and described needle handle 1 is provided with a plurality of apertures 4, described syringe needle 2 is the taper syringe needle, the lower end of described needle handle 1 is provided with switch 5, and the external diameter of described needle handle 1 is that 4mm, internal diameter are that 3mm, length are 12cm, during operation, abdominal paracentesis lavation pin is inserted in the abdominal cavity otch, connect drainage tube, open switch and carry out drain, whole device is convenient, safety.
