Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention is intended for use as a fixation table for ventricular drainage, and more specifically, for the purpose of controlling intracranial pressure by removing cerebrospinal fluid. This relates to a fixing table for continuous drainage of the ventricles, cerebral cisterns, and spinal cavities (hereinafter collectively referred to as ventricles).

[Prior Art] In the field of neurosurgery, continuous drainage of the ventricles, cisterns, and spinal cavities is used to control intracranial pressure when it increases due to various causes.

Shunt surgery is indicated for this type of ventricular drainage when there is increased intracranial pressure that cannot be controlled with drugs, or when it is necessary to remove blood-producing cerebrospinal fluid and infected cerebrospinal fluid over time. cases where this is not possible and there is an urgent need to reduce intracranial pressure for a period of time, cases where the configured system is used for the purpose of intracerebrospinal fluid infusion of antibiotics or hematoma lytic agents, etc.

This drainage method has a wide range of applications, and can be installed by a relatively simple surgery as an emergency treatment, so it is now widely used and its importance is increasing.

However, such drainage methods sometimes have management problems, such as blockage of the circuit, infection due to communication of the cerebrospinal fluid cavity with the outside world, and acute low spinal cord pressure due to rapid drainage of cerebrospinal fluid. .

Furthermore, with conventional drainage systems, fixing the drainage is complicated, pressure settings are not completely accurate, there are safety issues, and it is not always easy and reliable when multiple scales are required. Ta.

FIG. 5 shows a conventional drainage fixation method, in which the drainage is composed of a puncture section 10, a tube 11, a siphon section 12, and a drainage bag 13.

Conventionally, using the drainage with the above configuration, the puncture part 10 is inserted into the patient's ventricle 14, and the patient's external auditory foramen is aligned as the zero (0) point using the spirit level 15. The siphon part 12 was fixed to a board at the head of the bed with a bandage, and the drain bag 13 was fixed to the bed.

[Problems to be solved by the invention] However, the conventional drainage method described above poses the following problems.

Since it is fixed to a plate, it is difficult to know exactly how many centimeters the current pressure is being maintained, and changing the pressure is complicated.

Since the siphon part 12 is fixed with a bandage, there is a possibility that it may come off and fall, causing rapid drainage of cerebrospinal fluid, resulting in a lack of safety.

Fixing with a bandage is troublesome and does not look good. Furthermore, it is inefficient as it takes time to replace the bag.

If two drainage tubes are inserted, the above problems are doubled.

[Means for solving the problems] Therefore, in view of the above-mentioned conventional problems, the present inventor proposed the following:
As a result of extensive research in order to obtain a drainage system that can accurately measure the current pressure and easily change the pressure, we have arrived at the present invention.

That is, according to the present invention, a vertical rod having casters, and one or more scales held by the vertical rod and suspended vertically, the drainage siphon part suspension being movable up and down. A scale that is provided with a clip-like hook for lowering and is movably provided with a holding member that fits into and holds a tube below the drainage siphon;
A fixation stand for ventricular drainage is provided, comprising: a transverse rod having a spirit level connected to the zero point of the scale.

[Examples] The present invention will be described in more detail below based on the illustrated embodiments, but it will be clear that the present invention is not limited to these embodiments.

FIG. 1 and FIG. 2 each show an embodiment of the fixing table for ventricular drainage according to the present invention.
FIG. 1 is a perspective view, and FIG. 2 is a schematic explanatory diagram.

In the figure, 20 is a vertical rod stand having casters 21, 22 is two scales installed parallel to and perpendicular to the stand 20, and 23 is a drainage siphon part suspension that is attached to the scale 22 and is movable up and down. A lowering hook 24 is a horizontal rod formed by connecting the 0 points of two scales 22, respectively.
Reference numeral 5 indicates a level provided on the horizontal rod 24 or the stand 20, and reference numeral 26 indicates a hanger provided below the stand 20 for fixing the drain bag. Further, 27 indicates a drainage siphon part, 28 indicates a drainage bag, 29 indicates the 0 point of the scale, and 30 indicates the graduation of the scale.

The siphon part hanging hook 23, which is a siphon part fixing device, is as shown in FIG.
so that it can be moved up and down to match the desired pressure setting.
It is fixed to the scale 22 with screws 33.
The shape of the hook 23 is so-called a clip shape, and its structure is such that the hook 23 has a clip 34.
It consists of a fastening piece 35 with a . By configuring the hook 23 as described above, this problem can occur in the case of a normal hook shape. The drainage siphon part 27 does not come off or fall off due to contact or movement, and the danger of acute low spinal cord pressure etc. in the event of falling off can be avoided.

In addition to the hook 23 for hanging the drainage siphon part described above, the scale 22 has a tube 36 directly below the drainage siphon part 27 (a tube 36a from the ventricle to the siphon part 27 and a siphon part), as shown in FIG. Drain bag 2 from 27
A magnetic plate 37 and a retaining spring 38 that hold the two tubes 36b (up to 8 tubes 36b) are fitted therein.
By removably providing the holding member 39, the siphon portion 27 is fixed vertically, preventing any movement to the left or right or forward, thereby ensuring secure fixation. In this embodiment, the holding member 39 is made up of a magnetic plate 37 and a retaining spring 38, but in place of the magnetic plate, for example, a retaining screw that can slide the scale 22 up and down may be provided. A slide plate etc. can be used. Also, scale 22 is from +30cm to -50cm
It has a scale every 1cm up to the point, and a number every 10cm.

In FIG. 1, the spirit level 25 is attached to the 0 point of the two scales 22, respectively.
0 regardless of whether the stand 20 is placed on either side of the patient.
This makes it easy to set points. The spirit level 25 is attached to a horizontal bar 24, which is normally bent at a bending part 31, as shown in FIG. Its tip is locked to. On the other hand, as shown in FIG.
If it is installed at 0, only one spirit level is required, which is reasonable and economical, and is preferable.

In the above case, the scale 22 and the spirit level 25
is attached to the stand 20 by the horizontal rod 24 and the upper horizontal rod 32 using suitable attachment means such as screws, so that the scale 22 and the level 25 can be slid up and down at the same time.

Furthermore, the drain bag fixing hanger 26 is attached and fixed at the foot of the stand 20 to the extent that it does not touch the floor surface, but the two drain bag fixing hangers 28 (28a
and 28b) on one hanger 26, it would be time consuming and inconvenient to replace the bags. Therefore, it is preferable to have separate hangers 26 for each number of drainage bags, that is, for each number of drainage bags. .

The procedure for using the fixed table for ventricular drainage having the above configuration is as follows:
7 on the hanging hook 23, and the drain bag 28 is attached to the hanger 26 for fixing the drain bag.

Next, the zero point of the spirit level 25 is set.
The horizontal rod 24 is not lengthened, but the level gauge 25 is lengthened. Horizontal rod 24 is scale 22
and a level 25 is fixed to the stand 20. Then, the spirit level 25 extends left and right,
Zero point setting can be easily performed from either the left or right side of the patient.

In addition, Fig. 2 shows an example in which the left and right scales are linked when adjusting the zero point, but when adjusting the zero point when two or more patients are not treated at the same time, each scale and level must be adjusted. It is preferable to use a type that allows the containers to be moved up and down separately.

When changing the set pressure, loosen the screw 33 and attach the hook 23 for hanging the drainage siphon part.
move up and down to quickly and accurately expel cerebrospinal fluid at the desired pressure.

Furthermore, with the fixing table of the present invention, even if two drainage tubes are inserted into one patient, they can be easily managed with one stand, and their operating status can be easily observed.

In this embodiment, the case where two scales are provided is shown, but it is also possible to use one scale or a plurality of three or more scales.

[Effects of the Invention] As explained above, according to the fixing table for ventricular drainage of the present invention, the drainage pressure can be set and changed easily, quickly, and accurately.
