Description

Technical Field

[0001] The utility model relates to the technical field of brain surgery nursing, in particular to an ICU cranial brain cooling instrument. Background Art

[0002] Brain surgery generally refers to neurosurgery, which is a discipline that utilizes neurosurgery, mainly based on examination, surgery as a path, comprehensive treatment, and comprehensive evaluation. It is the youngest, most complex, and fastest-growing discipline in medicine. ICU, or Intensive Care Unit, provides isolation places and equipment for critically ill or comatose patients, and provides the best care. In brain surgery, the head temperature of patients with craniocerebral injury is usually proportional to the degree of brain injury. When the head temperature is too high, it is not conducive to the patient's recovery. Timely cooling of the brain can reduce the amount of cerebral hemorrhage and reduce intracranial pressure, so a craniocerebral cooling device is needed for cooling.

[0003] In most existing cranial and cerebral cooling devices, water cooling is used to cool the patient's head. If the water pressure inside the cranial and cerebral cooling device is too high, the water circulation of the cooling device will stop. In the ICU ward, medical staff are busy with work and it is difficult for them to find abnormalities in the cooling device. If the cranial and cerebral cooling device has abnormalities and is not handled in time, it will affect the patient's life safety. Therefore, an ICU cranial and cerebral cooling device is proposed to solve the above problem. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides an ICU cranial brain cooling device which can prevent excessive water pressure inside a body and can promptly warn of faults.

[0006] The pressure relief structure includes a connecting plate, which is fixedly installed on the right side of the water outlet pipe. A hydraulic cylinder is arranged at the bottom of the connecting plate, and a push block is fixedly installed at the piston end of the hydraulic cylinder. A pressure relief pipe is connected through the right side of the water outlet pipe, a switch plate is arranged on the right side of the pressure relief pipe, a drain pipe is arranged at the bottom of the pressure relief pipe, a containing plate is arranged on the top of the partition, and a connecting pipe is fixedly installed at the bottom of the containing plate.

[0007] Furthermore, a water inlet is provided on the top of the water storage tank, a through hole is provided on the top of the body, and an alarm is provided on the top wall of the body.

[0009] Furthermore, a flow meter is provided on the water inlet pipe, the water pump is fixedly mounted on the bottom wall of the machine body, a weight sensor is mounted on the containing plate, and the weight sensor is electrically connected to the alarm.

[0010] Furthermore, the water inlet pipe and the water inlet pipe are both fixedly connected to the ice cap, a cooling layer is provided on the surface of the ice cap, and the inner cavity of the cooling layer is a cavity.

[0011] Furthermore, a controller is fixedly installed on the top of the connecting plate, the pressure relief pipe is rotatably installed with a switch plate through a rotating shaft, and the rotating shaft sleeve is provided with a torsion spring, the connecting pipe is through-connected with the water inlet pipe, a leakage hole is provided on the containing plate, a submersible pump is provided in the water storage tank, and the water inlet pipe is connected to the submersible pump.

[0012] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0013] The ICU craniocerebral cooling instrument is provided with a pressure relief structure. If the water pressure in the craniocerebral cooling instrument is too high, the push block can be driven by the hydraulic cylinder output shaft to press down the switch plate, so that water can come out through the pressure relief pipe and the drain pipe. Moreover, since the switch plate is rotatably installed on the pressure relief pipe through a rotating shaft, and a torsion spring is sleeved on the rotating shaft, the switch plate is retracted due to the action of the torsion spring to close the pressure relief pipe, so that the outlet pipe can be intermittently depressurized to prevent excessive pressure relief. Excess water falls onto the containing plate through the drain pipe and enters the water inlet pipe through the connecting pipe, so as to prevent water waste. If the instrument is abnormal and the pressure cannot be relieved, the weight sensor will give an alarm signal when it cannot sense the impact of water, so that it will alarm, thereby reminding medical staff to repair the instrument in time. Through the above-mentioned settings, not only can the water pressure in the cooling instrument be prevented from being too high, but also the medical staff can be reminded in time to deal with it in case of abnormal pressure relief, so as to prevent the patient's life from being in danger.

[0022] A weight sensor is installed on the holding plate 127, and the weight sensor is electrically connected to the alarm. When the weight sensor cannot sense water, the alarm can be sounded. The water inlet pipe 10 and the water inlet pipe 8 are both fixedly connected to the ice cap 11. A cooling layer is provided on the surface of the ice cap 11, and the inner cavity of the cooling layer is a cavity.

[0023] When implementing, follow these steps:

[0024] 1) If the water pressure in the cooling device is too high, open the hydraulic cylinder 122 through the control console 2;

[0025] 2) Then the hydraulic cylinder 122 presses down the switch plate 125 through the push block 123 to open the valve of the pressure relief pipe 124, so that water can flow out through the pressure relief pipe 124 and the drain pipe 126;

[0026] 3) The switch plate 125 is then retracted due to the action of the torsion spring to close the pressure relief pipe 124, thereby intermittently relieving the pressure of the water outlet pipe 5;

If the instrument malfunctions and the pressure cannot be released, the weight sensor will send an alarm signal when it cannot sense the water impact.

[0028] In summary, the ICU craniocerebral cooling device is provided with a pressure relief structure 12.

Since the switch plate 125 is rotatably installed on the pressure relief pipe 124 through a rotating shaft, and a torsion spring is sleeved on the rotating shaft, the switch plate 125 is retracted due to the action of the torsion spring to close the pressure relief pipe 124, so that the water outlet pipe 5 can be intermittently depressurized to prevent In case of excessive pressure relief, excess water will fall onto the containing plate 127 through the drain pipe 126 and enter the water inlet pipe 8 through the connecting pipe 128, thereby preventing water waste. If the instrument malfunctions and the pressure cannot be relieved, the weight sensor will give an alarm signal when it cannot sense the impact of water, causing it to alarm, thereby reminding medical staff to repair the instrument in time. The above settings can not only prevent the water pressure in the cooling instrument from being too high, but also promptly remind medical staff to take measures in case of abnormal pressure relief, thereby preventing the patient's life from being in danger.
