In the utility model, an adapting pipe 1 and an inserting pipe 2 are stuck and connected with each other; one section the inserting pipe 2 being inserted in human bodies is of a curled shape and is provided with length marking line 4; the limiting value of the maximum outside diameter of the inserting pipe 2 can be contained by edge opening needles. The utility model has the advantages of fast draining process, easy control of the depth of the insertion pipe being inserted in thoracic cavity, fluent and fast draining, no discomfort of patient, etc. and is an ideal thoracic cavity occlusion drain device.

Description

With opening the integral type intrathoracic drain that the limit needle guide is gone into

This utility model relates to the medical devices technology, is specifically related to thoracic cavity inaccessible drain equipment technology.

The inaccessible drainage tube in existing thoracic cavity, as Chinese patent application number is 99228930.0, and it is described like that the application name is called the description of " the reassembling type intrathoracic drain that imports with biopsy needle ", exists patient's misery, deficiencies such as cross infection easily take place in general difficult grasp of surgical drainage.And above-mentioned " with the reassembling type intrathoracic drain of biopsy needle importing " that Chinese patent provided though can overcome the deficiencies in the prior art comprehensively, in clinical practice, still exists the intervention pipe and is easy to slippage from the endoporus of union joint or adapting pipe; Get involved pipe and insert patient's chest depth difficult grasp that put in place; Get involved pipe insertion patient thoracic cavity and can directly sting internal organs, and patient often feels uncomfortable; The pore footpath is less with getting involved, and the smooth prompt degree of drain is not good enough to wait deficiency.

The purpose of this utility model is to overcome the deficiency that above-mentioned application number is 99228930.0 patents, disposablely do not need to do the vascular forceps separating muscle and organizes implant surgery and provide a kind of, and with opening the integral type intrathoracic drain that the limit needle guide is gone into.

The purpose of realization this utility model has been taked following technical scheme: it still is made up of adapting pipe and intervention pipe institute, on the sidewall of getting involved the human body section of intervention pipe, is provided with a conduction hole that connects with its endoporus at least.And its improvement is, said adapting pipe becomes bonding with the intervention pipe and is connected, thereby formation one, the intervention human body section that gets involved pipe is curls shape, and be carved with the length mark line getting involved on the human body section of intervention pipe, and the maximum outside diameter of intervention pipe is its ultimate value with the endoporus institute that can be opened the limit pin normal the containing.

The virtual condition of opening limit pin habitual according to present hospital.The external diameter that this utility model is preferably got involved pipe is 2.5～5mm.

What should be illustrated here is that what is called is opened the limit pin, is apparatus commonly used in the general nephropathy operation.See also accompanying drawing 4 and accompanying drawing 5.

This utility model is that 99228930.0 disclosed technology are compared with number of patent application particularly with prior art, obviously exists to get involved the Guan Buhui slippage, and the drain process is smooth; Get involved pipe and insert the grasp that puts in place of patient's chest depth; Get involved Guan Buhui and directly stinging internal organs, and patient does not have uncomfortable sensation; It is bigger to get involved the pore footpath, characteristics such as the smooth victory of drain.

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

Fig. 1 is a configuration state schematic diagram of the present utility model;

Fig. 2 is the B-B cutaway view of Fig. 1;

Fig. 3 is the A-A cutaway view of Fig. 1;

Fig. 4 is the medical front view of opening the limit pin.

Fig. 5 is the right cutaway view of Fig. 4.

See also Fig. 1,2 and 3, this utility model is by adapting pipe 1 and get involved pipe 2 and be connected via cyclohexanone is bonding, and leakage problem must not take place.The intervention human body section that gets involved pipe 2 is curls shape, and its state of curling can be realized by adding thermal finalization.Being provided with 5 tangible length mark lines 4 on the outer wall of getting involved pipe 2, is equidistant between each markings, phase spacing 50mm, and getting involved pipe 2 is the no-toxicity medical polrvinyl chloride hollow tube of φ 3 * 0.3mm (wall thickness), and its two ends connect mutually.On the sidewall of getting involved pipe 4 intervention human body sections, be provided with the two row conduction holes 3 symmetrical, and every row is provided with 3 six of conduction holes with its axis.

This utility model product is a plastic.Adapting pipe 1 with get involved pipe 2 mutually bonding after, with the encapsulation of plastic film bag single-piece, behind the sterilizing of strictness, dispatch from the factory and use for hospital clinical.

Application state of the present utility model explanation is: the chest under patient's local anaesthesia cuts about 2～5mm skin layer tissue, will open the limit pin again and pass muscular tissue and thrust the patient thoracic cavity, then with intervention pipe 2 of the present utility model by opening limit pin endoporus, insertion patient thoracic cavity.According to each one personal feature, the selected insertion length that gets involved pipe 2 can be controlled by being located at the length mark line of getting involved on the pipe 24.After waiting to get involved pipe 2 and inserting the patient thoracic cavities and put in place, be about to out the limit pin and extract, and make and get involved pipe 2 and withdraw from by opening in the set vertically slotted eye of limit pin from patient's chest.Adapting pipe 1 being pegged graft with the glass tubing of drain vial is communicated with again, and just promptly implements normal surgical drainage.

Practical ranges of the present utility model is not subjected to the restriction of the foregoing description and application state explanation.

Claims (2)

1, a kind of usefulness is opened the integral type intrathoracic drain that the limit needle guide is gone into, it is made up of adapting pipe (1) and intervention pipe (2), on the sidewall of the intervention human body section that gets involved pipe (2), be provided with a conduction hole (3) at least, it is characterized in that, said adapting pipe (1) becomes bonding with intervention pipe (2) and is connected, the intervention human body section that gets involved pipe (2) is curls shape, and on the intervention human body section that gets involved pipe (2), be carved with length mark line (4), and get involved the maximum outside diameter of managing (2), be its ultimate value with the endoporus containing that can be opened the limit pin.
