Body external diameter at described positioning gasbag rear portion is provided with the centring ring that a damping is slided, and described centring ring has the large and small end face of different-diameter, and wherein said large end face radially is provided with some apertures.

Reasonablely be, it is the length mark of benchmark that described body external diameter surface indicates with described positioning gasbag middle part, and the small end face of described centring ring can be discerned its axial location on described body surface by this length mark.

Reasonable is that described top guide comprises shark's lip shape termination multilamellar conduction hole top guide.

Reasonable is that described top guide comprises the top guide of common termination.

Reasonable is that described intrathoracic drain comprises the silica gel material.

This intrathoracic drain provides a kind of convenient and reliable chest drainage apparatus for the clinician.Reduce the risk of chest drainage, improved quality of medical care.

The specific embodiment

Embodiment 1

See also accompanying drawing 1,1 (a) and shown in 2, body 1, top guide 2, positioning gasbag 3, centring ring 4, chamber 5 and the one-way cock 6 of can two-way localized intrathoracic drain comprising of the present utility model formed.

Wherein, include the full chamber 12 of drainage lumens 11 and air bag in body 1, be connected with the full hole 13 of an air bag mutually with the full chamber 12 of air bag, in addition, it is the length mark 14 of benchmark that body 1 external diameter surface indicates with positioning gasbag 3 middle parts.

Front end at body 1 is provided with a top guide 2, and top guide 2 has axial conduction hole 21 that communicates with body drainage lumens 11 and the some radially conduction holes 22 that communicate with axial conduction hole 21.

Positioning gasbag 3 is arranged at the symmetric position in the full hole 13 of air bag of the middle front part of body.The sheathed centring ring 4 of external diameter at the body 1 at positioning gasbag 3 rear portions.

Centring ring 4 structures see Fig. 3 (a) and 3 (b) for details, comprise large end face 41 and small end face 42, be close to patient's breast outer wall in clinical use, the profile of large end face 41 can be circle or other is non-circular, and small end face 42 indication centring rings 4 are at the length mark of the corresponding body 1 of axial location on body 1 surface.Some apertures 43 at centring ring 4 edges can be stitch-bonded to patient's chest wall 100 with centring ring 4.Centring ring 4 makes centring ring 4 that the slip of damping can be arranged at body 1 external diameter surface via the internal diameter Φ d size of three ribs control and the suitable interference of body 1 external diameter.

The rear end of body 1 is provided with chamber 5, and chamber 5 is made up of the full chamber of air bag that communicates with the full chamber 12 of body air bag respectively 52 and the drainage lumens that communicates with body drainage lumens 11 51.52 end is useful on the one-way cock 6 to positioning gasbag 3 full normal saline in the full chamber of air bag.

Positioning gasbag 3 in clinical after normal saline is full, patient thoracic cavity inwall is close on its right side.Centring ring large end face 41 is close to patient's breast outer wall, and the length mark of small end face 42 corresponding bodys 1 is represented the insertion depth position that intrathoracic drain of the present utility model is current.Guarantee that under positioning gasbag 3 and centring ring 4 co-located effects intrathoracic drain is not to inside and outside displacement of patient's body or unexpected coming off.

Intrathoracic drain of the present utility model can be made by medical silica-gel, with tissue, tissue fluid good biocompatibility, prevents the generation of adhesion and infection effectively, and indwelling time can reach 29 days.The also available material that other is suitable for.

Embodiment 2

See also Fig. 4,4 (a) and Fig. 5, than embodiment 1 different be that the top guide 2 of this intrathoracic drain is changed into the drainage tube of Trichiurus haumela lip termination multilamellar conduction hole top guide.Other structures are all identical in embodiment 1.

This utility model is when clinical use, after intrathoracic drain inserted the thoracic cavity, charge into the normal saline of rated capacity, pull intrathoracic drain backward to positioning gasbag 3 by one-way cock 6, make the positioning gasbag 3 after filling be affixed on the intrathoracic wall of patient, be close to patient's breast outer wall being pushed into before the centring ring 3.Aperture by centring ring 4 edges (not shown go out) is stitch-bonded to chest wall 100 with centring ring 3, or with suitable method fixing with patient's breast outer wall.Connect the hydrops bag in the end of drainage lumens 51 to store the body fluid of drain.

In case intrathoracic drain on position of the present utility model changes, the medical worker can judge the position of current intrathoracic drain immediately from the change in location of length mark on the body of small end face 42 correspondences of centring ring 4, whether should take suitable technical measures with decision.

More than all embodiment only for the explanation this utility model usefulness, but not to restriction of the present utility model, person skilled in the relevant technique, under the situation that does not break away from spirit and scope of the present utility model, can also make various conversion or variation, so all technical schemes that are equal to also should belong to category of the present utility model and should be limited by each claim.
