Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of medical auxiliary equipment, in particular to a portable and adjustable ventricular drainage tube fixing device. Background Art
[0002] At present, external ventricular drain (EVD) is a commonly used invasive operation in neurosurgery. It refers to the drainage of blood and fluid in the ventricles to the outside of the brain to reduce intracranial pressure (ICP) and clear bloody or infected cerebrospinal fluid. It is widely used in the drainage of intraventricular hemorrhage and hydrocephalus. EVD technology is also widely used in neurosurgery in my country.
[0003] The ventricular drainage tube is an important channel after EVD surgery. The safe care of the drainage tube is directly related to the patient's prognosis. The proper fixation and effective drainage of the drainage tube are the top priority of postoperative care for cranial surgery, which is directly related to the success or failure of the operation and affects the occurrence of postoperative complications in patients.
[0004] In the clinical nursing process, the placement height of the ventricular drainage tube has an extremely important impact on EVD and ICP, and the slightest carelessness may even endanger the patient's life. Normally, the ventricular drainage tube should be hung at the head of the bed, with the highest point of the drainage tube 10 cm to 15 cm above the plane of the lateral ventricle (lying flat: the horizontal plane of the midpoint of the line connecting the lateral canthus and the external auditory canal; lying on the side: the midsagittal plane). If the drainage tube is too high, it may lead to poor drainage, which will not reduce ICP, and there is a risk of tube blockage; if the drainage tube is too low, it may lead to excessive drainage, resulting in low ICP, and even intracranial hemorrhage or brain herniation in severe cases.
[0005] However, during the nursing process, since patients often need to change their body positions during treatment and nursing, the height of the drainage tube needs to be re-evaluated and measured after each position change. In addition, doctors also need to dynamically adjust the height of the ventricular drainage tube according to the patient's condition, ICP, and EVD. At present, the height of the ventricular drainage tube is often measured clinically using a ruler or a soft ruler. On the one hand, repeated measurements increase the time spent by nurses. On the other hand, this measurement method is highly arbitrary, there are human errors, and the data is not rigorous enough.
[0006] In addition, there is a consensus among experts that the intra-hospital transfer of patients with severe craniocerebral injury is also a risk factor for aggravating secondary brain injury. It is not recommended to routinely clamp the external ventricular drainage tube during intra-hospital transfer to avoid intracranial complications caused by clamping the drainage tube during transfer, especially for patients whose ventricular drainage tubes are open before transfer, whose ICP>15mmHg before transfer, and whose ICU has a large hourly cerebrospinal fluid drainage volume. At the same time, when transporting EVD patients, it is recommended to use a dedicated bracket to fix the sensor and drainage system. At present, the fixation of ventricular drainage tubes in clinical practice often uses cotton ropes to tie the drainage tubes and hang them on the ward oxygen inhalation device or infusion stand. It takes a long time to adjust the position of the drainage tubes, so it is not convenient for intra-hospital transfer and examination. When patients go out for examination and transfer, the drainage tubes are clamped and placed on the transfer bed, which also poses a greater risk of transfer. Summary of the invention

DETAILED DESCRIPTION
[0018] The utility model is further described below in conjunction with the accompanying drawings.
[0019] The portable and adjustable ventricular drainage tube fixing device of the utility model is as follows Figure 1 and Figure 2 As shown, it includes a pole 1, a holder 2 and a laser pen 3 arranged for horizontal irradiation. The lower end of the pole 1 is fixedly connected to the holder 2. The holder 2 and the pole 1 can be made of stainless steel. The lower end of the pole 1 can be welded to the holder 2. The laser pen 3 is arranged on the holder 2. The laser pen 3 is a product of the prior art. Figure 1As shown, the vertical pole 1 is provided with scales 101 arranged in the vertical direction, that is, the scale lines of the scales 101 are arranged in the vertical direction, and the vertical pole 1 is provided with a sliding sleeve of an adjustment seat 4, and the adjustment seat 4 is fixedly connected with a hook 5. The adjustment seat 4 and the hook 5 can be made of stainless steel, and one end of the hook 5 can be welded to the outer wall of the adjustment seat 4, and the adjustment seat 4 is screwed with a locking screw 7, and the adjustment seat 4 can be fixed on the vertical pole 1 through the locking screw 7. Specifically, the locking screw 7 is screwed through the wall of the adjustment seat 4, so that one end of the locking screw 7 can contact the vertical pole 1. When the locking screw 7 is tightened, the adjustment seat 4 is positioned on the vertical pole 1 through the friction between the vertical pole 1 and the inner wall of the adjustment seat 4 and the friction between the end of the locking screw 7 and the vertical pole 1. Since the vertical pole 1, the clamping seat 2 and the adjustment seat 4 are all made of stainless steel, they are durable, firm and not easy to deform or damage.
[0020] The following is a brief description of the method of using the portable adjustable ventricular drainage tube fixing device of the utility model: For patients with indwelling ventricular drainage tubes, the ventricular drainage tube fixing device of the utility model can be used to fix the ventricular drainage tube (referring to fixing the height position of the ventricular drainage tube). Specifically, firstly, the adjustment seat 4 is adjusted to the corresponding scale position according to the ventricular drainage tube height required by the doctor, and the locking screw 7 is tightened, that is, at this time, the distance between the hook 5 and the laser pen 3 has been properly fixed, so by observing the scale 101 and By operating and adjusting the position adjustment seat 4, the appropriate position of the hook 5 can be quickly and accurately set, and then the laser pen 3 is turned on, and the laser position is adjusted to the horizontal position of the lateral ventricle plane. During this period, the laser can be directly irradiated to the head, which is conducive to accurately adjusting the holder 2, keeping the laser position at the horizontal position of the lateral ventricle plane and fixing the holder 2 on the bedside infusion stand or other brackets, and then hanging the highest point of the drainage bottle on the hook 5. At this time, the height position of the laser emitted by the laser pen 3 to the distance from the highest point of the drainage bottle meets the doctor's requirements, and then the laser pen 3 is turned off. When the patient adjusts the body position, first turn on the power of the laser pen 3 on the holder 2, then move the holder 2 up and down to adjust the laser position to the horizontal position of the lateral ventricle plane, and finally fix the holder 2 again. Since the relative position of the laser pen 3 and the position adjustment seat 4 has been appropriately set according to the requirements, the relative position of the position adjustment seat 4 and the laser pen 3 does not need to be adjusted again. When the patient needs to be transferred, the holder 2 can be directly disassembled from the infusion stand or other brackets, so that the ventricular drainage tube fixing device of the utility model can be transferred with the patient. Specifically, the holder 2 can be fixed to the infusion pole of the transfer bed. During this period, the ventricular drainage tube can be quickly and appropriately moved to the transfer bed by only finding the position through the laser pen 3, without re-adjusting the relative position of the adjustment seat 4 and the laser pen 3, so that the ventricular drainage tube can maintain a normal working state when the patient is transferred. As can be seen from the above, the ventricular drainage tube fixing device of the utility model can accurately and quickly adjust the height of the ventricular drainage tube, and has good portability.
[0021] Furthermore, if Figure 2 As shown, the card base 2 includes a middle plate 21, a first side plate 22 and a second side plate 23. The two ends of the middle plate 21 are respectively connected to the first side plate 22 and the second side plate 23. The card base 2 is formed with a card slot entrance 201, and the card slot entrance 201 is arranged opposite to the middle plate 21. The first side plate 22 is screwed with a clamping hand wheel 6. The vertical rod 1 is fixedly connected to the outer side of the second side plate 23. Therefore, in the process of installing the card base 2, the card base 2 is first clamped on the pillar 99. The pillar 99 is arranged vertically. For example, the pillar 99 can be an infusion stand. That is to say, the pillar 99 relatively passes through the card slot entrance 201 to enter the card base 2, and then the clamping hand wheel 6 is tightened by hand. Make the inner end of the screw part of the clamping hand wheel 6 contact and press the pillar 99, so that the holder 2 is fixed on the pillar 99; when it is necessary to adjust the height position of the holder 2 to adjust the laser position to the horizontal position of the lateral ventricle plane, first loosen the clamping hand wheel 6, and then move the holder 2 up and down by hand, and the holder 2 slides on the pillar 99. When the position adjustment of the holder 2 is completed, retighten the clamping hand wheel 6; when it is necessary to transfer the ventricular drainage tube fixing device, first loosen the clamping hand wheel 6, and then pull the holder 2 away from the pillar 99 in the horizontal direction; by providing the above-mentioned holder 2, the portable and adjustable ventricular drainage tube fixing device of the utility model is convenient for assembly, disassembly, adjustment and carrying. The pillar 99 can be a square tube or a round tube, Figure 2 The case where the support 99 is a square tube is schematically shown.
[0022] Furthermore, if Figure 2 As shown, the laser pen 3 is arranged on the outer side of the middle plate 21. For example, a blind hole can be processed on the outer side of the middle plate 21. The tail of the laser pen 3 is adapted to be inserted into the above-mentioned blind hole and fixed by glue. Since the clamping handwheel 6 is arranged on the first side plate 22 and the vertical pole 1 is arranged on the second side plate 23, the laser pen 3 is arranged on the outer side of the middle plate 21 to prevent the vertical pole 1 or the clamping handwheel 6 from interfering with the observation and operation of the laser pen 3.
[0023] Furthermore, if Figure 1 As shown, the hook 5 is formed with a hook bottom end 501, the lower end of the adjustment seat 4 is arranged at the same height as the hook bottom end 501, the scale 101 includes a scale zero position 1011, and the laser pen 3 is arranged at the same height as the scale zero position 1011, which specifically refers to the laser emitted by the laser pen 3 and the scale zero position 1011 being arranged at the same height. When the drainage tube is hung on the hook 5, since the upper end of the drainage tube is at the position of the hook bottom end 501, the position of the drainage tube relative to the laser pen 3 can be known by observing the reading at the lower end of the adjustment seat 4, so that the distance from the scale zero position 1011 of the vertical pole 1 to the lower end of the adjustment seat 4 (that is, the reading of the lower end of the adjustment seat 4 on the scale 101) represents the height from the drainage tube to the plane of the lateral ventricle, so that the nurse can accurately adjust the height of the drainage tube to the plane of the lateral ventricle according to the doctor's requirements to avoid mistakes.
[0024] like Figure 1 As shown, at least two hooks 5 are distributed around the vertical pole 1, so that it is convenient for the nurse to hang the drainage tube on the hook 5 at a suitable position.
[0025] In summary, the utility model solves the shortcomings of conventional and existing ventricular drainage tube fixing methods and height adjustment methods, facilitates timely and accurate adjustment of the height of the ventricular drainage tube, reduces the workload of nurses, provides more accurate and effective information for doctors to diagnose and evaluate the patient's condition, reduces the occurrence of complications, and ensures patient safety; the disassembly and adjustment operation of the ventricular drainage tube fixing device of the utility model is simple, easy to master, and convenient to transport and carry.
