Abstract

The utility model discloses a disassembling and assembling type thoracic cavity drain pipe which is led in by abiopsy needles. In the utility model, the maximum limiting value of the outer diameter of an insertion pipe can pass through an inner hole of the biopsy needle. The utility model is matched with a biopsy needle for disposable use for simplifying existing thoracic cavity drain operation, has the advantages of small wound of patient, basically no pain, no occurrence of cross infection by disposable use and is an ideal thoracic cavity occlusion drain medical device for clinic at present.

Description

Reassembling type intrathoracic drain with the biopsy needle importing

This utility model relates to the medical devices technology, is specifically related to a kind of chest drainage equipment technology.

The inaccessible drainage tube in existing medical thoracic cavity is " mushroom " shape, and the diameter of its " mushroom head " has 15～20mm approximately, " mushroom bar "---and promptly getting involved its diameter of pipe has 10mm approximately, is druggist rubber sundrier, uses in clinical repeated multiple times.This prior art when hospital clinical uses, needs to implement the chest incision implant surgery.Existing undoubtedly this technology exists following deficiency: wound is big first, and 1～2cm is arranged, and has increased misery to patient; Second will do vascular forceps separating muscle tissue, after reaching the thoracic cavity, reuse vascular forceps clamping " mushroom head " part makes it to implant the thoracic cavity, and the general doctor of this operation is difficult for grasping; Three because of drainage tube uses repeatedly, and easily cross infection takes place.

The purpose of this utility model is to provide a kind of reassembling type disposable thoracic drainage pipe that imports with biopsy needle of it goes without doing chest incision implant surgery, thereby fundamentally solves the deficiencies in the prior art.

Specifically, the purpose of this utility model is to take following two technical schemes that come from an inventive concept to realize.

One of technical scheme: it is made up of adapting pipe, connection tube, union joint and intervention pipe.The connection tube two ends respectively with bonding connection of shell of the endoporus and the union joint of adapting pipe, become the stressed joint of pegging graft movingly with the endoporus of union joint and get involved pipe, get involved the hollow tube that pipe connects for two ends, its external diameter be its maximum limit passing through the biopsy needle endoporus, on the sidewall at the intervention torso model position of getting involved pipe, be provided with a conduction hole that connects with its mesopore at least.

Two of technical scheme: it is made up of adapting pipe 1 and intervention pipe, and get involved pipe and become the stressed joint of pegging graft movingly with the endoporus of adapting pipe 1, get involved the hollow tube that pipe connects for two ends, its external diameter be its maximum limit passing through the biopsy needle endoporus, on the sidewall at the intervention torso model position of getting involved pipe, be provided with a conduction hole that connects with its mesopore at least.

This utility model adopts hospital's biopsy needle commonly used that it is imported the thoracic cavity, and its operation is simple; Patient's wound is little, basic no pain; Characteristics such as cross infection can not take place in disposable use, are conspicuous.

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

Fig. 1 is the schematic diagram of a kind of structure of the present utility model;

Fig. 2 is the A-A cutaway view Amplified image of Fig. 1;

Fig. 3 is the schematic diagram of another kind of structure of the present utility model, and its B-B face cutaway view is as (providing its diagrammatic sketch no longer in addition) shown in Figure 2.

Fig. 4 is a present hospital biopsy needle schematic diagram commonly used.

One of embodiment; See also Fig. 1,2.This utility model it by with glass or the banded adapting pipe 1 of lucite pipe socket joint, connection tube 2, the union joint 3 of the disposable monotype water-sealed drainage bottle of inaccessible drain vial or up-to-date use with get involved 4 of pipes and form.Getting involved pipe 4 be the soft no-toxicity medical polrvinyl chloride hollow pipe that φ 2.5 * 0.3mm two ends connect, and is getting involved on the sidewall of managing 4 intervention torso model position, and it is 12mm and diameter is the conduction hole 5 of 1.2mm that both sides respectively are provided with 3 phase spacings.The bonding binding of cyclohexanone is adopted with the endoporus of adapting pipe 1 and the shell of union joint 3 respectively in connection tube 2 two ends, and guarantees never to leak.Get involved pipe 4 then with the stressed joint of pegging graft movingly of 3 one-tenth of union joints.All products of this utility model are plastic.This utility model manufactured goods adopt the encapsulation of single piece of plastic bag film, and use for hospital clinical through dispatching from the factory behind the strict sterilizing.

Two of embodiment; See also Fig. 3, this utility model it by being used for pegging graft and getting involved the insertion pipe 1-1 of pipe 4 except established one section more, other is all formed with corresponding to adapting pipe 1 shown in Figure 1 and intervention pipe 4, and its correlation behavior explanation is consistent with the state description of one of the foregoing description.The structure of Fig. 3 wants simple than above-mentioned Fig. 1,2 structure, but can realize the purpose of this utility model equally.

Being described as follows of application state of the present utility model, the biopsy of pleura pin (see figure 4) that adopts the production of Jiading, Shanghai City Intelligent Instrument Watch Factory is as importing utensil.At first make its nook closing member insert needle tubing, extract nook closing member out after waiting to thrust the thoracic cavity, to get involved pipe 4 again and insert the patient thoracic cavity by the needle tubing endoporus, waiting to get involved pipe 4 inserts in the thoracic cavities and after putting in place, the biopsy needle needle tubing is extracted in the patient body, and withdraw from by exsertion part one end of getting involved pipe 4 then, and then will get involved the endoporus that pipe 4 inserts the insertion pipe 1-1 of union joint 3 (Fig. 1) or adapting pipe 1 (Fig. 3), can implement surgical drainage.In order to prevent exempting to get involved pipe 4 slippage from the endoporus of the insertion pipe 1-1 of union joint 3 or adapting pipe 1, it is fixing that available adhesive tape will be got involved pipe 4.

Clinical application range of the present utility model is not subjected to the restriction of above description.
