Anti-siphon device for hydrocephalus drainage tube

The present invention relates to an anti-siphon device for a hydrocephalus drainage tube, and particularly to a hydrocephalus drainage tube for draining a patient, which prevents the patient from sitting up or standing up in the hydrocephalus drainage tube. Larger siphoning action to avoid excessive suction of hydrocephalus anti-siphon device.

According to the appearance of hydrocephalus, the circulation pathway of cerebrospinal fluid (CSF) is blocked, and the absorption and secretion of cerebrospinal fluid are not balanced, causing excessive cerebrospinal fluid to be absorbed by the human body and accumulated in the ventricles. In most cases, the hydrocephalus cannot be cured and exists for life. However, by diverting the cerebrospinal fluid to other parts of the body through surgery, it can usually improve the patient's overall improvement.

Today, the most standard method for treating hydrocephalus is ventriculo-peritoneal shunt surgery. The operation usually diverts excess cerebrospinal fluid to the abdominal cavity and is absorbed by the body. Please refer to Figure 1 to install a ventricle drainage in the ventricle. a tube 11 and a peritoneal drainage tube 12 is disposed in the abdominal cavity. A unidirectional control valve 13 is disposed between the ventricular drainage tube 11 and the abdominal drainage tube 12, so that excess cerebrospinal fluid in the ventricle can pass through the ventricular drainage tube. The one-way control valve 13 and the abdominal drainage tube 12 are drained to the abdominal cavity and absorbed by the human body. The one-way control valve 13 can control the cerebrospinal fluid flow, flow direction and pressure, and the doctor can set the patient according to the condition. The one-way control valve 13 is of different pressure to guide the cerebrospinal fluid to the abdominal cavity in.

However, when the patient is lying down, sitting or standing, the negative pressure of different siphon action is generated in the ventricular drainage tube 11 and the abdominal drainage tube 12, especially the patient is converted from sitting to standing or standing. In the posture, the ventricular drainage tube 11 and the abdominal drainage tube 12 generate a large siphon effect, and excessive drainage is relatively inconvenient.

It can be seen that there are still many shortcomings in the above-mentioned household items, which is not a good designer and needs to be improved.

In view of the shortcomings of the aforementioned prior art, the creator is based on the experience and technical accumulation of various medical supplies, and carefully researches various solutions to the above-mentioned problems. After continuous research, experimentation and improvement, the author finally develops and designs the creation. The creation of an anti-siphon device for a new type of hydrocephalus drainage tube, in order to eliminate the lack of prior art.

The main purpose of this creation is to provide an anti-siphon device for hydrocephalus drainage tube, which is used to prevent the patient from sitting up or standing up in the hydrocephalus drainage tube when the hydrocephalus drainage tube drains the hydrocephalus of the patient. Produces a larger siphon effect to avoid excessive aspiration of hydrocephalus.

According to the above object, the anti-siphon device of the brain hydrocephalus drainage tube of the present invention mainly comprises: a ventricle drainage tube, a abdominal drainage tube, a one-way control valve and an anti-siphon device; wherein the ventricular drainage tube The device is installed in the ventricle; the abdominal drainage tube is installed in the abdominal cavity, and is connected to the ventricular drainage tube; the one-way control valve is disposed between the ventricular drainage tube and the abdominal drainage tube, and controls the cerebrospinal fluid flow Flow direction (flow from the ventricle to the abdominal cavity) and pressure; the anti-siphon device is provided with a guiding tube, the guiding tube is disposed on the one-way control valve, the abdominal cavity Between the flow tubes, the guiding tube is provided with an inflow tube, the inflow tube is in communication with a ring tube, and the annular tube is in communication with the two symmetric middle tubes, and the two tubes are connected to the first-stage tube, so that The one-way control valve enters the cerebrospinal fluid, and can flow into the annular tube through the inflow tube, and then flows from the two symmetric middle tube to the outflow tube, and finally flows out from the outflow tube to the abdominal drainage tube; An upper cover body and a lower cover body are disposed on the upper and lower cover bodies to directly and downwardly cover the surface of the guide tube and press on the upper and lower sides of the annular tube, thereby relieving the flow rate of the cerebrospinal fluid by pressing; Thereby, when the hydrocephalus of the draining patient is performed, the cerebrospinal fluid of the hydrocephalus can be slowed down by the compression of the upper and lower covering bodies to prevent the hydrocephalus drainage tube from sitting or standing up due to the patient. Produces a larger siphon effect to avoid excessive aspiration of hydrocephalus.

The third figure is an exploded view of the anti-siphon device of the creative hydrocephalus drainage tube.

Fig. 4 is a schematic view showing the use of the anti-siphon device of the creative hydrocephalus drainage tube.

This creation is about an anti-siphon device for hydrocephalus drainage tubes. Please refer to Figures 2 and 3 for the anti-siphon of the created hydrocephalus drainage tube. The device 20 mainly comprises a ventricle drainage tube 21, a peritoneal drainage tube 22, a one-way control valve 23 and an anti-siphon device 24.

The ventricular drainage tube 21 is installed in the ventricle.

The abdominal drainage tube 22 is mounted in the abdominal cavity and is connected to the ventricular drainage tube 21.

The one-way control valve 23 is disposed between the ventricular drainage tube 21 and the abdominal drainage tube 22, and controls cerebrospinal fluid flow, flow direction (flow from the ventricle to the abdominal cavity), and pressure.

The anti-siphon device 24 is provided with a guiding tube 25 disposed between the one-way control valve 23 and the abdominal drainage tube 22. The guiding tube 25 is provided with an inflow tube 251, and the inflow tube 251 is A ring-shaped tube 252 is in communication with the two-symmetric middle tube 253, and the two-way tube 253 is in communication with the first-stage outlet tube 254, so that the cerebrospinal fluid entering the one-way control valve 23 can be The annular tube 252 flows into the annular tube 252 through the inflow tube 251, and then flows from the two symmetric middle tube 253 to the outflow tube 254, and finally flows out to the abdominal drainage tube 22 from the outflow tube 254. Further, the guiding tube 25 is provided with an upper cover. The body 26 and the lower cover body 27, the upper and lower cover bodies 26, 27 cover the surface of the guide tube 25 just above and below, and are pressed against the upper and lower sides of the annular tube 252, thereby relieving the cerebrospinal fluid by pressure. Flow rate.

By means of the composition of the above components, as shown in Fig. 4, when the hydrocephalus of the draining patient is performed, the cerebrospinal fluid of the hydrocephalus can be relieved by the pressure of the upper and lower covering bodies 26, 27 to prevent the flow. The patient sits up or stands up to produce a larger siphon effect in the hydrocephalus drainage tube to avoid excessive aspiration of hydrocephalus.

Referring to Figures 2 and 3, the upper and lower covers 26, 27 may be an elastic silicone material.

The anti-siphon device of the hydrocephalus drainage tube provided by the present invention has the following advantages when compared with the conventional techniques described above: 1. When the hydrocephalus drainage tube drains the hydrocephalus of the patient, the patient can be prevented from being affected by the patient. Sit up or stand up to create a larger siphon in the hydrocephalus drainage tube to avoid excessive aspiration of hydrocephalus.

In summary, the anti-siphon device of the created hydrocephalus drainage tube has an unprecedented innovative structure, which has not been seen in any publication, and there is no similar product on the market, so it is novel. It should be undoubted. In addition, the unique features and functions of this creation are far from comparable to the conventional ones, so it is indeed more progressive than the application, and it meets the requirements of the application requirements of the new patents in the Chinese Patent Law, and is legally filed.
