Background
Neurosurgery is mainly used for treating diseases of nervous systems of brain, spinal cord and the like caused by trauma, such as life threatening due to cerebral hemorrhage and bleeding amount, brain trauma caused by car accidents, or operation treatment required by brain tumor compression. In neurosurgery of each large hospital, when carrying out the treatment processes such as brain tumour, serious intracranial injury and hypertension cerebral hemorrhage to patient, can produce a large amount of hydrops (blood or liquid medicine etc.), often need use drainage device to carry out the drainage to the hydrops (blood or liquid medicine etc.) that patient's cranium oozed, must use drainage device.
At present, the used drainage device of each big hospital adopts the drainage bag that uses soft materials to make more, be equipped with the drainage tube on the drainage bag, this kind of drainage bag simple structure, low cost, can reduce patient's medical cost, but this kind of drainage bag exists the imbibition effect relatively poor, place the position requirement also higher to the drainage bag during use, need medical personnel in time to observe simultaneously, the situation that can't carry out effective drainage prevents to appear, influence going on of patient's recovery and operation, make medical personnel's intensity of labour greatly increased, and present automatic drainage equipment structure is complicated, the volume ratio is bigger, inconvenient receive and release and carry.
The utility model discloses a chinese utility model patent application publication number is CN209933595U discloses a drainage device for neurosurgery, the on-line screen storage device comprises a base, rubber support pad is installed to the bottom of base, and the both sides of base install the handle, install switch board and waste liquid collection tank on the base, switch board internally mounted has storage battery and controller, and the negative pressure pump is installed at the top of switch board, sealed lid is installed at the top of waste liquid collection tank, and waste liquid collection tank top portion intercommunication has negative pressure pipe and is responsible for, the negative pressure pipe is kept away from the one end of waste liquid collection tank and is linked to each other with the negative pressure pump, and the one end of being responsible for keeping away from the waste liquid.
The utility model discloses a shortcoming that exists: above-mentioned utility model is after the waste liquid drainage, the drainage tube still has the waste liquid, can appear the problem of waste liquid refluence, leads to the drainage not thorough.
Therefore, the inventor provides a drainage device for neurosurgery by taking the experience of abundant design development and actual manufacturing in the related industry for years as a basis and researching and improving the existing structure and deficiency, so as to solve the problems.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve traditional drainage device after the waste liquid drainage, the drainage tube still has the waste liquid, can appear the problem of waste liquid refluence.
In order to achieve the purpose, the utility model discloses a basic scheme provides a drainage device for neurosurgery, including holding the liquid bottle, can dismantle on holding the liquid bottle and be equipped with the end cover, end cover one side is run through and is equipped with the negative pressure pipe, and negative pressure pipe one end is located and holds the liquid bottle, and the other end is equipped with the negative pressure pump, is equipped with the air-vent valve on the negative pressure pipe, and the end cover middle part is equipped with the manometer, and the end cover runs through with negative pressure pipe relative one side and is equipped with the adapter sleeve, and it has the through-hole to open in the adapter sleeve.
The principle and effect of this basic scheme lie in:
the utility model discloses the body type is small and exquisite, conveniently carry, adopt when using simply fixed can, arrange the position that needs the drainage in the current-limiting room, through the air-vent valve, the negative pressure pump passes through the negative pressure pipe and adjusts the atmospheric pressure that holds in the liquid bottle, through the atmospheric pressure in the barometer real-time detection holds the liquid bottle, the atmospheric pressure that makes the liquid bottle that holds is less than external atmospheric pressure, external atmospheric pressure presses the waste liquid into from the current-limiting room through the drainage tube and holds the liquid bottle, after the drainage finishes or when needing to change the drainage position, lift the drainage tube, the waste liquid refluence in the drainage tube can effectively be prevented to the check valve in the current-limiting room, traditional drainage device has been solved after the waste liquid drainage, the waste liquid.
Further, a sealing ring is fixedly arranged between the end cover and the bottle mouth of the liquid storage bottle. The air pressure in the liquid storage bottle is prevented from leaking from the joint of the end cover and the liquid storage bottle, so that the failure of air pressure regulation is avoided.
Furthermore, sealing sleeves are arranged at the contact parts of the negative pressure pipe, the pressure gauge and the connecting sleeve with the end cover. The air pressure in the liquid storage bottle is prevented from leaking from the contact part of the negative pressure pipe, the pressure gauge and the connecting sleeve and the end cover, so that the air pressure regulation is disabled.
Furthermore, a dial is arranged on the surface of the liquid storage bottle, and a maximum liquid level line is arranged on the dial. The waste liquid volume is conveniently observed to the calibrated scale, and the biggest liquid level line is used for warning medical personnel, prevents to spill over the negative pressure pump and leads to the negative pressure pump to damage after the accumulator bottle fills with.
Further, the liquid storage bottle is in threaded connection with the end cover. Convenient dismantlement, the drainage is finished the back and is just poured the waste liquid.
