Abstract

The utility model provides an encephalic compression hemostasis drainage catheter, and comprises a front end, a body end and a tail end of the drainage catheter. The drainage catheter is characterized in that a circular cuff is arranged at the front end of the catheter, and the cuff is communicated with a free air (water) charging device at the tail end of the drainage catheter through an air breather (water) catheter on the catheter wall. 2 to 3 long circular points distributed uniformly and accreted with the out wall of the drainage catheter are arranged on the circular cuff wall. A long circular hole arranged in the adhesive center penetrates through the cuff wall and the drainage catheter wall, and the hole is not communicated in the cuff, but is mutually communicated with a catheter inner cavity. 2 to 3 irregular invisible grooves arranged on the cuff wall are connected with the long circular hole. The utility model is characterized in that the catheter is put after encephalic haematoma is sucked and irrigated, then air (water) is filled to the cuff through the free air (water) charging device to lead the cuff to expand, blood capillary around a haematoma cavity is compressed, and the purpose of compression haemostasia is achieved. Through side holes at the front end of the drainage catheter, the invisible grooves and the long circular hole on the cuff drain peripheral blood oozing and accumulation liquid outside a skull, thereby playing the double functions of the compression haemostasia and drainage.

Description

Intracranial hemostasis by compression drainage catheter

Technical field:

This utility model belongs to medical apparatus, particularly a kind of intracranial hemostasis by compression drainage catheter.

Background technology:

The intracranial drainage catheter of present clinical use is existing multiple, purpose is by drainage catheter, and the hematoma that the intracranial a variety of causes is caused, hematocele, hydrops drain are to cranium, to avoid the hematoma compression cerebral tissue, cause that the cranium pressure increases and the functional areas afunction purpose of reach treatment, curing.But these conduits have drawback, when removing haematoma cavity, and when placing drainage tube, often can not rapid closing because of haematoma cavity, small blood capillary oozing of blood takes place often.Weight person, capable again surgical hemostasis, the lighter prolongs healing stage, convalescence, has increased the defective of patient's misery and health care expenditures.

Summary of the invention:

The technical problem that this utility model solves is to provide a kind of intracranial hemostasis by compression drainage catheter, after the broken suction of intracranial hematoma, removing, places this conduit, utilizes the special tectonic of conduit, can hemostasis by compression, and again can the drain hematocele, the dual purpose of hydrops.

The technical solution of the utility model realizes: a kind of intracranial hemostasis by compression drainage catheter, it has catheter proximal end, body end and the tail end of drainage tube, it is characterized in that: catheter proximal end has a circular cover capsule, its two ends adhere on the catheter wall, and this capsule is communicated with the free inflation of tail end of conduit (water) device by catheter wall, ventilation (water) conduit.The oval point-like and the catheter wall adhesion that on circular cyst wall, have 2-6 to be evenly distributed, adhesion central authorities have the Long Circle hole to run through cyst wall and catheter wall, and (this hole with capsule in be not communicated with) communicates with conduit cavity, has 2-6 bar stealth ditch to be connected with the Long Circle hole on the cyst wall.

Above-mentioned hemostasis by compression drainage catheter, preceding top are blind sharp nose circle, and side has two asymmetric oval foramens, continue the initial part of 0.3-0.5 centimetre for circular cover capsule and the adhesion of conduit annular backward.

Above-mentioned circular cover capsule two ends are the 2-4 centimetre apart from length, and capsule rear end and the adhesion of catheter wall annular are the rear portion.

2-3 oval point-like and catheter wall adhesion that is evenly distributed arranged on the above-mentioned circular cyst wall, and adhesion central authorities have the Long Circle hole to run through cyst wall and catheter wall communicates with conduit cavity, and wide footpath, Long Circle hole is the 0.1-0.2 centimetre, and major diameter is the 0.15-0.3 centimetre.

The irregular stealthy ditch of 2-3 bar is arranged on the above-mentioned circular cyst wall, and the stealthy ditch in inflation (water) back appears, and diameter is the 0.1-0.3 centimetre.

Description of drawings

Accompanying drawing: this utility model intracranial hemostasis by compression drainage catheter structural representation.

As shown in the figure: a kind of utility model intracranial hemostasis by compression drainage catheter, it by conduit Fig. 1, conduit before the other oval foramen Fig. 2 of dome, circular cover capsule Fig. 3, cover ductus bursae Fig. 4, inflation (water) installation drawing 5, connect cyst wall, the Long Circle hole pattern 6 of catheter wall, stealthy ditch Fig. 7, scale Fig. 8, bell mouth shape tail end Fig. 9, drainage tube and lead core Figure 10 and form above-mentioned this utility model overall structure.

Embodiment:

A kind of novel intracranial hemostasis by compression drainage catheter, after the broken suction of the intracranial hematoma of being expert at, the removing, drainage tube is led core Figure 10 to be inserted in drainage tube Fig. 1 tube chamber as support, the degree of depth, centimetre number, metering drainage catheter scale Fig. 8 according to puncture needle insert haematoma cavity according to puncture needle direction, position, the degree of depth with conduit.Extract and lead core and according to the sucking-off quantity of hematoma, gas injection (water) in conductive pipe inflation (water) installation drawing 5, by cover ductus bursae Fig. 4, make the circular cover of catheter proximal end capsule Fig. 3 expansion, purpose is to make in the haematoma cavity that can not seal at once after the hematoma clearance flushing to form certain pressure, compressing stops haematoma cavity small blood capillary on every side, and oozing of blood forms hematoma defective (but gas injection (water) amount should be less than the 20-30 milliliter than sucking-off amount in the cover capsule).For residual blood, can pass through conduit bell mouth shape tail end Fig. 9 drain along the chamber to cranium external drainage bottle with the slotted hole Fig. 6 conductive pipe intracavity that connects cyst wall, catheter wall by oval foramen Fig. 2 before the conduit.Circular cover capsule peripheral blood, can be on cyst wall stealthy ditch Fig. 7 to slotted hole Fig. 6 drain.Hemostasis by compression cover capsule can be oppressed situation according to drain, and gas (water) volume in the cover capsule that successively decreases every day is beneficial to the haematoma cavity closure, and it is abundant to reach drain, avoids sending out the defective of hematoma again.

Intracranial hemostasis by compression drainage catheter is compared with existing drainage catheter, has useful effect to be, can drain oozing of blood hydrops, can oppress the dual function of small blood capillary oozing of blood again.
