Description

Drainage and local hypothermia treatment device {DRAINAGE AND LOCAL HYPOTHERMIC TREATMENT DEVICE}

The present invention relates to a drainage and local hypothermia treatment apparatus, and more particularly, to a drainage and local hypothermia treatment apparatus for drainage and hypothermia treatment of a surgical site of the brain after decompressive craniectomy or craniotomy. will be.

Hypothermia treatment is performed to induce hypothermia in patients with traumatic brain injury, acute cardiac arrest, ischemic stroke, and cerebral hemorrhage, thereby reducing cerebral blood flow and lowering brain metabolism and intracranial pressure, thereby minimizing brain damage and inducing neurological symptom recovery. Hypothermia treatment, which lowers the temperature of the brain, can alleviate cerebral edema and increased brain pressure.

Since the brain is protected by the skull and scalp, it is difficult to effectively lower the temperature of the brain through local hypothermia therapy. In general, systemic hypothermia therapy is performed to lower the body temperature of the whole body in order to lower the temperature of the brain. However, when systemic hypothermia is performed to lower the temperature of the brain, the body temperature of other parts of the patient's body in addition to the brain region requiring hypothermia is lowered, so there is a risk of complications.

On the other hand, in the case of decompressive craniectomy, craniotomy, etc., since the patient's brain is exposed to the outside, local hypothermia treatment that lowers the temperature of the brain, not the whole body, may be considered. In addition, exudate accumulates at the surgical site after craniotomy. If the exudate is not removed, infection and swelling may occur. In order to prevent this, a drainage pipe that discharges the exudate to the outside is used. The drainage tube is inserted into the surgical site and discharges the exudate out of the body through negative pressure.

In such a situation, there is a growing need to develop a treatment device that enables effective local hypothermia therapy at the same time as well as drainage of exudate accumulating at the surgical site after craniotomy.
