Abstract

The utility model relates to an indwelling drainage needle which comprises a needle core and a needle tubing. The needle core is installed in the needle tubing, one end of the needle core is arranged as a cusp, the cusp extends out of the needle tubing, and the other end of the needle core is connected with a needle holding handle. The needle holding handle is arranged outside the needle tubing, a plurality of drainage holes are formed in the outer wall, close to the needle core, of the needle tubing of the cusp. The end of the needle tubing close to the needle holding handle is provided with a catheter, one end of the catheter is communicated with the inner side of the needle tubing, and the other end of the catheter is provided with a connecting cap. According to the indwelling drainage needle, the needle tubing is brought into a to-be-drained position by the needle core with the cusp, and then the needle core is pulled out, the needle tubing is left in the to-be-drained position and a negative-pressure system is inserted, and therefore the drainage is conducted. Drainage effect is good due to arrangement of drainage holes in the needle tubing. According to drainage structure, the needle tubing is matched with the catheter, and the drainage and cleaning of injured areas can be conducted in a matching mode. The indwelling drainage needle is convenient to use, wide in application scope, simple in operation and small in trauma.

Description

A kind of drainage from indwelling pin

Technical field

This utility model relates to a kind of drainage from indwelling pin, particularly a kind ofly is applicable to process the hematocele of closed injury place and the drainage from indwelling pin of hydrops, belongs to the medical apparatus technical field.

Background technology

Skin is the tissue that covers human body surface, is easy at the volley to be subject to the damage due to the violence; Closed injury is that the skin mucosa of injury keeps integrity, and deep tissues does not have exposed damage; Or when spraining, if the paranormal abnormal movement in joint and cause the damage of juxtra-articular ligament and joint capsule.Damage location hematocele hydrops can appear in closed injury usually, the symptoms such as arthroedema, and these liquid then need excrete; When and for example producing the exfoliative damage of limbs, skin and subcutaneous 's hematocele hydrops need to be discharged, skin is resetted and be adjacent to muscle and gradually healing; At this moment just need to use the drainage needle of these closed injurys for the treatment of; When usually processing the hematocele hydrops of above position, need to carry out the repeated localised puncture suction to the part with ordinary syringe, need patient's compounding practice, and drain be not thorough, often need how long to puncture, especially can not finely cooperate for the child, have very large danger; If use needle tubing one to extract, too loaded down with trivial details again, repeated localised puncture has caused unnecessary wound to human body with managing.

The utility model content

This utility model purpose is that a kind of be applicable to the process hematocele of closed injury place and the drainage from indwelling pin of hydrops are provided in order to overcome the deficiencies in the prior art.

For achieving the above object, the technical solution adopted in the utility model is: a kind of drainage from indwelling pin comprises nook closing member, needle tubing; Described nook closing member is arranged in the needle tubing; One end of described nook closing member is arranged to tip; Described tip stretches out needle tubing, the other end of nook closing member with hold needle handle and link to each other; Describedly hold the outside that needle handle is positioned at needle tubing; The needle tubing outer wall of one end of the tip of described close nook closing member is provided with a plurality of conduction holes; Described needle tubing near holding an end of needle handle is provided with conduit; One end of described conduit communicates with the inside of needle tubing, and the other end of conduit is provided with attachment cap.

Preferably, the tip of described nook closing member is prismatic.

Preferably, described a plurality of conduction hole evenly distributes.

Preferably, described a plurality of conduction hole is evenly distributed on the needle tubing outer wall.

Because the utilization of technique scheme, this utility model compared with prior art has following advantages:

The drainage from indwelling pin of this utility model scheme by needle tubing being brought into the position that needs drain with acuminous nook closing member, is extracted nook closing member again, and needle tubing is stayed needs drain place, and can easily carry out drain at needle tubing access negative pressure system this moment; This drainage from indwelling pin is easy to use, applied widely, and simple to operate, and syringe needle can reduce wound with prismatoidal design, and the conduction hole that arranges on the needle tubing can make the drainage effect of this drainage from indwelling pin better; The flow guiding structure that needle tubing cooperates with conduit can make drain and the flushing of injury cooperated and carry out.

Description of drawings

Below in conjunction with accompanying drawing technical solutions of the utility model are described further:

Accompanying drawing 1 is the front view of drainage from indwelling pin described in the utility model;

Accompanying drawing 2 is the partial sectional view of drainage from indwelling pin described in the utility model;

Wherein: 1, nook closing member; 2, needle tubing; 3, hold needle handle; 4, conduction hole; 5, conduit; 6, attachment cap.

The specific embodiment

The utility model is described in further detail below in conjunction with drawings and the specific embodiments.

Accompanying drawing 1-2 is a kind of drainage from indwelling pin described in the utility model, comprises nook closing member 1, needle tubing 2; Described nook closing member 1 is arranged in the needle tubing 2, and needle tubing 2 braces nook closing member 1; The pin heart 1 is the metal needle heart, and needle tubing 2 is flexible pipe; One end of described nook closing member 1 tip stretches out needle tubing 2, and the tip of nook closing member 1 is prismatic; The other end of described nook closing member 1 with hold needle handle 3 and link to each other; Describedly hold the outside that needle handle 3 is positioned at needle tubing 2; On the described needle tubing 2, an end of the tip of close nook closing member 1 is provided with a plurality of equally distributed conduction holes 4; The described uniform length of conduction hole 4 on the outer wall of needle tubing 2 has different size; Described each conduction hole 4 is through hole; On the described needle tubing 2, be provided with conduit 5 near an end of holding needle handle 3; One end of described conduit 5 communicates with the inside of needle tubing 2, and the other end of conduit 5 is provided with attachment cap 6; Can connect negative pressure system on described conduit 5 or the needle tubing 2 and carry out drain, the reason of perhaps delivering a child saline etc. washes.
