Description

Chronic subdural hematoma washes drainage tube

Technical Field

The utility model belongs to the field of medical equipment, concretely relates to drainage tube is washed to chronic subdural hematoma.

Background

The existing chronic subdural hematoma flushing drainage tube is mostly a drainage tube with multiple side holes clinically, the flushing and the drainage share one tube cavity, after the drainage tube is placed at a proper position below a subdural membrane, a large-capacity injector is connected at the tail end of the flushing drainage tube, and sterile normal saline is injected into the drainage tube after air is exhausted so as to reach the subdural membrane, thereby playing a role in flushing the hematoma cavity. After a proper amount of normal saline is flushed, the injector is pulled out, the flushed old blood and saline flow out through the dura mater incision gap and the flushing drainage tube, then the injector is fully pumped with the normal saline again, and the flushing drainage tube is connected again. The flushing and drainage are repeated until the color of the drainage liquid becomes light.

During the flushing process, and when the syringe is connected and pulled out, air is easy to enter the subdural and brain tissue surface from the fissure of the dural incision carelessly. A small amount of gas can cause discomfort such as headache of a patient, if the gas leaks into the patient, tension type air skull and brain tissue compression can be caused, the patient has intracranial high pressure manifestations such as nausea, vomiting, disturbance of consciousness and the like, and the patient is seriously threatened to life.

In contrast, the current clinical preventive measures are to order the patient to lie on the side, fix the position of the skull with the head ring, make the drainage part of the drilled hole located at the highest position of the skull, and use gelatin sponge to fill the gap of the dura mater incision during flushing. However, as the flushing progresses, the tamponade is often flushed away by the flushing fluid, and after most of the hematoma is flushed out, the brain tissue of the patient cannot rebound immediately, but the brain tissue beats, and air can be sucked to continue to enter the subdural space and the surface of the brain. In addition, chronic subdural hematoma is often a local anesthesia operation, a patient is a patient of a larger age, the patient cannot endure the long-term maintenance of the same posture, the skull slightly rotates, and when the drilling drainage position is no longer at the highest position, gas can be drilled into brain tissue by means of a machine.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a drainage tube is washed to chronic subdural hematoma to solve chronic subdural hematoma drilling drainage operation in-process air and get into intracranial problem easily.

The technical scheme of the utility model is that: the utility model provides a chronic subdural hematoma washes drainage tube, includes the body, and the body both ends are open, and it has two gasbags to wrap up in the body periphery, and intercommunication each other between two gasbags, is connected with the gas tube on one of them gasbag, and the body is inside to be equipped with the interlayer, separates into two parallel lumens in the body, is washing pipe and drainage tube respectively, and the afterbody of washing pipe and drainage tube is equipped with the valve respectively.

As a further improvement of the utility model, a side hole is arranged on the head end of the flushing pipe to one section of the pipe wall of the air bag. The flushing water can flow out through the side holes on the flushing pipe, so that the flushing range is wider.

As a further improvement of the utility model, a side hole is arranged on the head end of the drainage tube to one section of the tube wall of the air bag. During drainage, the side hole on the drainage tube can also form a drainage channel to accelerate drainage.

As a further improvement of the utility model, the distance between the two air bags is 0.5 cm. The thickness of the skull of a general adult is 1.0cm, and the distance between the two air bags is set to be 0.5cm, so that the skull can be conveniently clamped between the two air bags and can be stably fixed.

As a further improvement of the utility model, the distance between the air bag and the head end of the pipe body is 6-8 cm.

As a further improvement of the utility model, the tail parts of the flushing pipe and the drainage pipe are mutually separated, so that the liquid supply device is convenient to connect and other operations are realized.

The utility model has the advantages that:

1. the utility model discloses set up two gasbags at the body periphery, the body head end is placed encephalically after, aerify to the gasbag through the gas tube, make the skull card between two gasbags, on the one hand, the gasbag plays the effect of fixing the body, on the other hand, two gasbags aerify the inflation, can play the effect of sealing the bone hole after closely contacting with the skull, through the structure of gasbag + barrier of liquid, cut off the route that gas got into encephalically from skull bone hole and dura mater operation incision, effectively reduced the gaseous possibility that gets into encephalically;

2. after the air bag and liquid barrier is formed, the change of the body position of a patient in the operation and the pulsation of brain tissue can not cause gas to enter the cranium from the bone hole and the dural operation incision;

3. the flushing pipe and the drainage pipe in the utility model are mutually independent, the flushing pipe can be connected with a large-capacity injector or a continuous liquid supply device, the valve on the drainage pipe is closed before flushing, when a certain flushing amount is reached, the valve on the flushing pipe is closed, the valve on the drainage pipe is opened for drainage, and then the flushing-drainage process is repeated, in the process, drainage can be carried out without pulling out the liquid supply device, the operation is convenient, and air is prevented from being introduced when the liquid supply device is connected and pulled out;

4. by using the utility model, extra gelatin sponge is not needed to be filled in the operation, the operation process is simplified, and the risk caused by the gelatin sponge being flushed out is eliminated;

5. the utility model discloses simple structure, it is with low costs, easily industrialization.
