Claims

1. A pressure-regulated balloon apparatus positioned in a cavity to prevent negativities caused by cavities formed in the brain after brain and nerve surgery, characterized by comprising: a main balloon which provides a soft support to the brain with air/water pumped into it; a security balloon outside the skull; a double-channel probe pumping air/water into the security balloon with said main balloon and draining the existing air/water; a valve positioned on the probe to throw out the air/water in the main balloon by opening automatically when the brain pressure exceeds the normal.

2. The pressure-regulated balloon apparatus according to claim 1, further comprising a neck positioned between the main balloon and the security balloon, remaining in between the cortex, bone and scalp to prevent the pressure-regulated balloon apparatus from sliding in and out.

3. The pressure-regulated balloon apparatus according to claim 1, wherein said valve comprises a piston that moves according to the pressure created in the brain, a spring that moves the piston forward by compressing in case the cylinder exceeds the brain pressure and that prevents the output of the air/water by opening when the pressure decreases and an output end from which the air/water is drained.

4. The pressure-regulated balloon apparatus according to claim 1, further comprising a reserve valve positioned at the end of the valve, opening while pushing the reserve air/water and then closing to prevent the reserve from being deflated.

5. The pressure-regulated balloon apparatus according to claim 1, wherein said reserve valve is obtained by inverting the valve.

6. The pressure-regulated balloon apparatus according to claim 1, wherein said probe is a Foley probe.

DETAILED DESCRIPTION OF THE INVENTION

[0040] In this detailed description, the pressure-regulated balloon apparatus (Dadalon) (10), positioned in said cavity to prevent the negativities caused by the cavities formed in the brain (B) after the brain and nerve surgery is merely described for a better understanding of the subject and without any limiting effects.

[0041] The pressure-regulated balloon apparatus (10) of the invention provided in FIG. 1, in terms of its general structure, consists of the main balloon (11) providing a soft support to the brain (B) with the air/water pumped into it, the security balloon (13) outside of the skull (K), the double-channel probe (14) pumping air/water into the security balloon with said main balloon (11) and draining the existing air/water, the valve (15) positioned on the probe to throw out the air/water in the main balloon (11) by opening automatically when the brain (B) pressure exceeds the normal.

[0042] The main balloon (11) of the pressure-regulated balloon apparatus (10) is a normal balloon which is positioned in the brain (B) and in which the probe (14) is inserted after being sterilized. Said probe (14) is the Foley probe. The main balloon (10) is inflated such that it fills the cavity formed in the brain (B) by means of air/water through the probe (14). Then, the security balloon (13) which is outside the skull (K), is also inflated by giving air/water with the probe (14). In FIG. 4, a representative view of the pressure-regulated balloon apparatus (Dadalon) (10) applied to the brain (B) after the removal of cyst and tumor is provided.

[0043] The neck (12) positioned between the main balloon (11) and the security balloon (13) is located between the brain membranes, bone and scalp to prevent the pressure-regulated balloon apparatus (Dadalon) (10) from sliding in and out.

[0044] In FIG. 2, when the brain pressure is low, the valve (15) whose general view is given, is pressure regulated, and comprises the piston (151) moving according to the pressure formed in the brain (B), the spring (152) moving the piston (151) forward (A direction) by compressing in case of the cylinder exceeds the brain pressure and preventing the output of the air/water by opening when the pressure decreases and the output end (153) from which the air/water is drained.

[0045] The valve (15) is pressure-regulated and the spring (152) is compressed when the pressure exceeds 15 cm of water where the pressure-regulated balloon apparatus (10) is the exit foramen of the pressure-regulated balloon apparatus (10) in the brain (B), and the piston (151) moves forward (A direction) to throw away the air/water in the main balloon (11) from the output end (153). Thus, in order to prevent the increase of intracranial pressure to be formed by the expanding brain and to prevent the brain (B) from being under pressure, the volume of the main balloon (11) is shrinking in the X direction and an expansion in the brain (B) is provided. The diameter of the main balloon (11) shrinking by itself in this way is removed when it is less than 2 cm in few days. In FIG. 3, the general view of the valve (15) when the brain pressure increases is provided. In FIG. 5, the representative view of the pressure-regulated balloon movement (10) during the normalization process of the brain (B).

[0046] There is a non-automated reserve valve (16) with 30 cm water pressure-regulated at the end of the valve (14), where the security balloon (13) has an exit foramen, opening while pushing the reserve air/water and then closing to prevent the reserve from being deflated. The reserve valve (16) is obtained by inverting the valve (15).

[0047] The application of the pressure-regulated balloon apparatus (Dadalon) (10) has provided very successful results in the use after the cysts and tumor surgeries. It prevents the intracranial pressure increase to be formed by the expanding brain (B) and the pressure of the brain (B) and provides expansion in the collapsed brain (B). The main balloon (11) which is under the increased pressure shrinks by itself in X direction and prevents the complications such as pressure increase in the brain (B), bleeding, folding of the brain vessels and decreasing of the flow and stopping.

[0048] The pressure-regulated balloon apparatus (10) of the invention can be used after the brain hemorrhage surgeries.
