Description

Technical Field

[0001] This utility model relates to fixation devices, and in particular to a fixation device for external drainage of cerebrospinal fluid. Background Technology

[0002] Cerebrospinal fluid (CSF) is a colorless and transparent fluid found in the ventricles and subarachnoid space of the brain. External drainage of CSF is a clinical treatment method that drains cerebrospinal fluid through lumbar puncture. It is often used to drain hemorrhagic CSF, inflammatory CSF, and to control rapidly progressing hydrocephalus in a short period of time.

[0003] During external cerebrospinal fluid drainage, the drainage tubing, drip bottle, collection bag, and intracranial pressure gauge used for drainage need to be fixed in place, maintaining the drainage height and neutral position. Current fixation devices are inconvenient to use when supporting and securing the drainage equipment, and they cannot quickly and accurately locate the horizontal position of the patient's external auditory canal when determining the drainage height. Therefore, a new external cerebrospinal fluid drainage fixation device is proposed to address these issues. Utility Model Content

[0004] This embodiment provides a cerebrospinal fluid external drainage fixation device to address the problems mentioned in the background art.

[0005] According to one aspect of this utility model, a cerebrospinal fluid external drainage fixation device is provided, including a fixed support plate and a connecting plate. The connecting plate is fixed to the bottom end of one side of the fixed support plate by bolts. An elastic hanging plate is fixed to the top end of the connecting plate. An intracranial pressure scale is provided on the other side of the fixed support plate, and a marking block is provided on the intracranial pressure scale. Fixed parts are installed at both the upper and lower ends of one side of the intracranial pressure scale, and a lead screw is rotatably arranged between the fixed parts. A lead screw nut that can make horizontal linear movement on the lead screw is sleeved on the lead screw, and a laser pointer is installed on the lead screw nut. An upper hanging plate is fixed to the top end of the intracranial pressure scale and is hung on a support rod. The side of the support rod is fixed to the fixed support plate. Lower support plates are engaged at the bottom ends of both sides of the intracranial pressure scale and are fixed to the fixed support plate. A hanging groove that cooperates with the support rod is opened inside the upper hanging plate.

[0006] Furthermore, the height of the fixed support plate is greater than the sum of the heights of the intracranial pressure scale and the upper hanging plate, the width of the fixed support plate is greater than the width of the intracranial pressure scale, and both the fixed support plate and the connecting plate have fixing holes inside.

[0007] Furthermore, the elastic hanging plate is configured as an inverted "J" shape, and an anti-slip pad is glued to the bottom upper part of the elastic hanging plate, and the width of the anti-slip pad is equal to the width of the elastic hanging plate.

[0008] Furthermore, the intracranial pressure scale has limiting plates engaged at the middle of both sides, and the sides of the limiting plates are fixed to the fixed support plate. Both limiting plates are configured as horizontally placed "L" shapes that cooperate with the intracranial pressure scale.

[0009] Furthermore, the lower diameter of the hanging groove is larger than the upper diameter of the hanging groove.

[0010] Furthermore, both of the lower support plates are configured in an "L" shape to mate with the bottom of the intracranial pressure scale.

[0011] The above embodiments of this utility model employ a clip-on fixing component. The fixing support plate can be hung on the edge rail of the hospital bed through the elastic hanging plate. The laser pointer that can move up and down can help to quickly and accurately find the horizontal position of the patient's external auditory canal, which greatly improves the convenience of using the fixing device and makes it easier to maintain the drainage height.

[0023] Please see Figure 1-3 As shown, the cerebrospinal fluid external drainage fixation device includes a fixing support plate 1 and a connecting plate 2. The connecting plate 2 is fixed to the bottom end of one side of the fixing support plate 1 by bolts; an elastic hanging plate 3 is fixed to the top end of the connecting plate 2; an intracranial pressure scale 6 is provided on the other side of the fixing support plate 1, and a marking block 11 is provided on the intracranial pressure scale 6. Fixing parts 5 are installed at both the upper and lower ends of one side of the intracranial pressure scale 6, and a lead screw 10 is rotatably arranged between the fixing parts 5. A sleeve is fitted on the lead screw 10. There is a lead screw nut 14 that can make horizontal linear motion on the lead screw 10, and a laser pointer 15 is installed on the lead screw nut 14. The top of the intracranial pressure scale 6 is fixed with an upper hanging plate 7, and the upper hanging plate 7 is hung on the support hanging rod 8. The side of the support hanging rod 8 is fixed on the fixed support plate 1. The bottom ends of both sides of the intracranial pressure scale 6 are engaged with lower support plates 9, and the side of the lower support plates 9 is fixed on the fixed support plate 1. The upper hanging plate 7 has a hanging groove 12 that cooperates with the support hanging rod 8.

[0024] This invention uses a micro motor to drive the lead screw 10 to rotate, causing the lead screw nut 14 to move horizontally linearly on the lead screw 10, which in turn moves the laser pointer 15 up and down. The vertically movable laser pointer 15 allows the intracranial pressure scale 6 to be quickly aligned with the patient's external auditory canal.

[0025] In this embodiment, the height of the fixing support plate 1 is greater than the sum of the heights of the intracranial pressure scale 6 and the upper hanging plate 7, and the width of the fixing support plate 1 is greater than the width of the intracranial pressure scale 6. Fixing holes are provided inside both the fixing support plate 1 and the connecting plate 2. This ensures that the fixing support plate 1 can protect the intracranial pressure scale 6 and facilitates the fixing of the fixing support plate 1 and the connecting plate 2.

[0026] In this embodiment, the elastic hanging plate 3 is configured as an inverted "J" shape, and an anti-slip pad 4 is glued to the bottom of the upper part of the elastic hanging plate 3, and the width of the anti-slip pad 4 is equal to the width of the elastic hanging plate 3; the anti-slip pad 4 can increase the friction between the elastic hanging plate 3 and the bed frame.

[0027] In this embodiment, the midpoints of both sides of the intracranial pressure scale 6 are engaged with limiting plates 13, and the sides of the limiting plates 13 are fixed on the fixed support plate 1. Both limiting plates 13 are configured as horizontally placed "L" shapes that cooperate with the intracranial pressure scale 6.

[0028] In this embodiment, the lower diameter of the hanging groove 12 is larger than the upper diameter of the hanging groove 12; this facilitates the hanging plate 7 being hung on the support rod 8.

[0029] In this embodiment, both lower support plates 9 are configured as "L" shapes that mate with the bottom of the intracranial pressure scale 6.

[0030] When using this utility model, if a fixing device is required, first, the intracranial pressure scale 6 is fitted onto the bed rail, then the patient's external auditory canal is positioned horizontally using the laser pen 15, and then the intracranial pressure scale 6 is inserted into the limiting plate 13. At the same time, the upper hanging plate 7 is hung on the support hanging rod 8.

[0031] The circuits, electronic components, and modules involved are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated upon. The content protected by this utility model does not involve any improvement to the software and methods.

[0032] The above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
