After the conventional intracerebroventricular hemorrhage person conducts intracerebroventricular catheterization drainage, or when the intracerebroventricular hemorrhage of a patient or intracerebral hematoma drainage is insufficient, hematoma recurrence is easily caused, when a thin drainage tube with good compliance is clinically applied, the tube is very easy to block, the treatment purpose cannot be achieved, and when a drainage tube with a large tube diameter is applied, the tail end of the drainage tube has poor compliance, and brain tissues are very easy to damage particularly during tube drawing. Sometimes diluted urokinase is needed to be repeatedly washed in a tube cavity, when a brain is washed, two drainage tubes are generally needed to be inserted into the head of a patient, one drainage tube is used for injecting washing liquid medicine, and the other drainage tube is used for drainage, so that operation wounds and risks are increased, the operation is complex, and the operation time is prolonged.
Although a double-cavity ventricular drainage tube appears in clinical use, the diameter of the cavity of the drainage tube is too small, so that the tube is easily blocked, and continuous drainage cannot be realized.

The double-cavity ventricular drainage tube better solves the problem of simultaneous drainage and flushing, but cannot solve the problem of blockage of the drainage tube.
For another example, patent ZL201320011610.2 discloses a pus drainage double-cavity tube, which comprises a flushing tube and a drainage tube, the flushing tube is divided into a head part, a body part and a tail part, the head part is round and blunt, the front end of the flushing tube is provided with two tube openings of the double-cavity tube, the tail part flushing tube and the drainage tube are separated into a Y shape, the tube wall of the head part of the double-cavity tube, which is positioned at one side of the drainage tube, is provided with a plurality of liquid inlet holes, and the peripheries of the tube openings and. The double-cavity drainage tube has the advantages that the drainage tube wall is provided with the plurality of liquid inlet holes, so that the problem of easy blockage can be solved, but the head of the double-cavity drainage tube is of a straight tube structure, and tissues and organs are easy to be accidentally injured during drainage.
In conclusion, the existing drainage tube has the problem of easy blockage, is particularly not well suitable for the drainage tube of pathological cavities in brain tissues, is very easy to block because the brain tissues are soft and fragile, and the thin drainage tube is very easy to block, but the thick drainage tube has poor compliance, and the brain tissues are very easy to be damaged when the drainage tube is pulled out to cause heavy bleeding, thereby greatly increasing the operation risk.
It will thus be seen that the prior art is susceptible to further improvements and enhancements.

Detailed Description
The present invention will be described in further detail with reference to the following drawings and specific examples, but the present invention is not limited to these examples.
As shown in FIGS. 1 to 3, a drain tube includes a drain tube body. The drainage tube body comprises a head part 1, a middle part 2 and a tail part 3 which are connected in sequence. The drainage tube body is internally provided with a washing cavity 4 and a drainage cavity 5.
The drainage cavity 5 comprises a drainage liquid inlet section 51, the drainage liquid inlet section 51 is located at the head of the drainage tube body, the head of the drainage tube body comprises a plurality of strip-shaped parts 12 which are mutually separated, a liquid seepage gap 11 is formed between every two adjacent strip-shaped parts 12, and each liquid seepage gap 11 is communicated with the drainage liquid inlet section 51. The drainage cavity 5 further comprises a drainage fluid outlet section 52, and the drainage fluid outlet section 52 is located at the tail 3 of the drainage tube body.
As shown in FIG. 5, when the head 1 of the drainage tube body has no external force, the strip parts 12 are scattered, and the liquid seepage gap 11 is enlarged. As shown in figure 4, when the head part 1 of the drainage tube body is restrained by external force, the strip parts 12 are gathered together, and the liquid seepage gap 11 is reduced. Moreover, under the action of external force constraint, the strip-shaped parts 12 are matched together to form a whole body in a round and blunt pointed cone shape, and the pointed cone shape is convenient for the insertion of the drainage tube.
The flushing cavity 4 comprises a working fluid inlet section 41, and the working fluid inlet section 41 is located at the tail 3 of the draft tube body. The flushing cavity 4 further comprises a working fluid outlet section 42, the working fluid outlet section 42 is located at the head of the drainage tube body, and the head of the drainage tube body is provided with a liquid seepage hole 43 communicated with the working fluid outlet section 42. The liquid-permeable hole 43 is opened in one of the strip-shaped portions 12.
It should be noted that the head 1 of the drainage tube body is not limited to be provided with one weep hole 43, and may be provided with a plurality of weep holes, each weep hole 43 may be opened on one of the strip-shaped portions 12, or each strip-shaped portion 12 may be provided with one or more weep holes 43.
In order to be conveniently butted with a clinical liquid pipeline, the tail end of the working liquid inlet section is provided with a pipe joint 6.
The working solution inlet section 41 and the drainage solution outlet section 52 are separated from each other, and the working solution inlet section 41, the drainage solution outlet section 52 and the middle part 2 of the drainage tube body are matched together to form a Y-shaped structure.
As shown in fig. 6, when the drainage tube is actually used to drain the brain intra-cavity space, before the drainage tube is inserted, a channel 7 is first pre-punctured in the cranium by using a clinical existing apparatus to communicate with a hematoma cavity 8; since the brain tissue 9 is soft, elastic tissue, the channel is closed after the instrument is withdrawn. Then the drainage tube is inserted into the cranium along the channel 7, in the insertion process, the head part 1 of the drainage tube body firstly enters the channel 7, due to the extrusion effect of the constraint force of the side wall of the brain tissue 9 (the direction of the arrow in fig. 6 shows the direction of the constraint force of the side wall of the brain tissue), each strip part 12 is contracted into a taper-shaped whole, and the head part 1 of the drainage tube body advances along the channel until entering the hematoma cavity 8. After entering the hematoma cavity 8, the constraining force of the side wall of the brain tissue disappears, the strip parts 12 of the head part 1 of the drainage tube body become a dispersed state, the working solution enters the hematoma cavity 8 through the washing cavity 4, and then after mixed cerebral hemorrhage, the working solution enters the drainage cavity 5 from the weeping gap 11 and flows out, so that the complete cleaning process is completed. When each strip-shaped part 12 of the head part 1 of the drainage tube body is in a scattering state, the liquid seepage gap between the strip-shaped parts is increased, so that the passing area of drainage liquid is increased, and the drainage efficiency is improved. When the drainage tube is pulled out, the above change process occurs in reverse order.
