DETAILED DESCRIPTION
[0021] The present application will be further described below in combination with specific drawings and embodiments.
[0022] Embodiment 1
[0023] As shown in the drawings, Figure 1 Figure 2 Embodiment 1 discloses a ventricular drainage tube fixing support device, which comprises a main support 1 and a drainage height regulator. The main support 1 is the support basis of the whole ventricular drainage tube fixing support device, and the main support 1 can adopt an existing infusion support that can meet the installation requirement in clinical use. The drainage height regulator is installed on the main support 1, and the purpose of the drainage height regulator is to place the drainage container 2 and adjust the height of the outlet of the ventricular drainage tube.
[0024] In this embodiment 1, the height regulator is mainly composed of zero point adjusting support 3 and height adjusting scale 5, the zero point adjusting support 3 is slidingly installed on the vertical rod 1.1 of the main support 1, the zero point adjusting support 3 is provided with locking knob 4 for locking the vertical rod 1.1 and zero setting mechanism for determining zero point; the zero setting mechanism comprises laser pen 6 and pen clamp 7, the pen clamp 7 is installed on the zero point adjusting support 3 through pin shaft with damping, the top of the pen clamp 7 is provided with level 8, and the laser pen 6 is clamped in the pen clamp 7. The height adjusting scale 5 is vertically slidingly installed on the zero point adjusting support 3, and the zero point adjusting support 3 is internally provided with scale lifting adjusting mechanism; the scale lifting adjusting mechanism comprises gear 9, rotating shaft 10 and adjusting hand wheel 11, the zero point adjusting support 3 is internally provided with installation cavity, the gear 9 is fixedly installed on the rotating shaft 10, the rotating shaft 10 is rotatably installed on the zero point adjusting support 3 at both ends, and the rotating shaft 10 is provided with adjusting hand wheel 11 at one end and extends out of the side wall of the zero point adjusting support 3 and is fixedly installed; the height adjusting scale 5 is installed beside the gear 9, and one side of the height adjusting scale 5 is provided with gear teeth engaged with the gear 9; the side wall of the height adjusting scale 5 is fixedly connected with cross rod 12, and the cross rod 12 is provided with container hook 13.
[0025] The working process and working principle of the ventricular drainage tube fixing support device are as follows:
[0026] 1. Initially, the drainage container 2 (drainage bottle or drainage bag) is hung on the container hook 13, and the top inlet of the drainage container 2 is connected with the outlet end of the ventricular drainage tube. Before adjusting, the patient's position is adjusted to a suitable position, and then the height regulator is adjusted.
[0027] 2. First, loosen the locking knob 4 to allow the zero point adjusting support 3 to move up and down along the vertical rod 1.1; then close the valve on the ventricular drainage tube, adjust the position of the zero point adjusting support 3 using the zero setting mechanism, so that the height of the zero point adjusting support 3 is flush with the lateral ventricle plane height (positioning the tragus when lying down, and positioning the nasal midline when lying on the side); the specific method is to first adjust the outgoing light of the laser pen 6 to be horizontal using the level 8, and then adjust the position of the zero point adjusting support 3 according to the outgoing light of the laser pen 6, which is convenient and fast to operate.
[0028] 3. Rotate the adjusting hand wheel 11 in the scale lifting adjusting mechanism, the adjusting hand wheel 11 drives the height adjusting scale 5 to move up and down through the gear 9, and when the height adjusting scale 5 moves, it will drive the drainage container 2 hung on the container hook 13 to move up and down synchronously, so that the drainage container 2 can be quickly and accurately adjusted to the appropriate height by combining the scale on the height adjusting scale 5, so that the cerebrospinal fluid is uniformly drained, and the height is adjusted according to the patient's condition in the later period.
[0029] As Figure 1 , Figure 2As shown, in this embodiment 1, auxiliary supports 14 are mounted at the upper and lower ends of the height adjustment scale 5. One end of the auxiliary support 14 is fixedly connected to the end of the height adjustment scale 5, and the other end of the auxiliary support 14 is provided with a sliding cylinder 14a, which is slidably connected to the vertical rod 1.1. This arrangement ensures that the height adjustment scale 5 is highly stable during the upward and downward movement, thereby improving the safety of ventricular drainage.
[0030] like Figure 1 、 Figure 2 As shown, in this embodiment 1, a drainage fluid observation and comparison board 15 is further mounted on the outer end of the crossbar 12. A ball head rod 16 is provided at the upper end of the drainage fluid observation and comparison board 15. A ball seat 17 with a locking nut is provided on the side wall of the crossbar 12. The ball head of the ball head rod 16 is embedded in the ball seat 17. With this arrangement, the drainage fluid observation and comparison board 15 can be folded away in another location that does not affect operation when not in use. When the color of the cerebrospinal fluid needs to be observed, the position of the drainage fluid observation and comparison board 15 only needs to be adjusted so that the drainage container 2 is close to the surface of the drainage fluid observation and comparison board 15, so that clear and accurate observation can be made.
[0031] Example 2
[0032] like Figure 3 As shown, Example 2 discloses a ventricular drainage tube fixing bracket device, which differs from Example 1 in that it provides another zeroing mechanism. In actual clinical applications, other instruments and equipment may be placed near the patient's bed. The placement of the main bracket 1 may prevent the laser pointer 6 from directly irradiating specific parts of the patient's body (such as the external ear tragus or the midline of the nose due to the obstruction of the bedside). In this case, zeroing using a traditional level is difficult.
[0033] Therefore, this embodiment 2 provides another zero calibration mechanism that can solve the above-mentioned problem. The zero calibration mechanism includes a kettle 18, an indicator liquid and a transparent hose 19. The kettle 18 is fixedly installed on the zero point adjustment support 3. The indicator liquid is contained in the kettle 18. The water outlet at the lower end of the kettle 18 is connected to the transparent hose 19. A clamp 20 is installed on the transparent hose 19. The kettle 18 is also provided with an air vent connected to the atmosphere. The air vent and the other end of the transparent hose 19 are covered with a breathable and water-blocking film.
[0034] When the zero-calibration mechanism is not used, the transparent hose 19 is stored in a storage bag which is hung on the main support 1. When the zero-calibration mechanism is needed, the transparent hose 19 is first taken out, and the clamping device 20 on the transparent hose 19 is opened, at this time, the indicating liquid in the water bottle 18 flows into the transparent hose 19 naturally; then the transparent hose 19 is pulled to the external auditory meatus or the nasal midline of the patient, and then the height of the zero-point adjusting support 3 is adjusted, so that the liquid level of the indicating liquid in the transparent hose 19 is flush with the external auditory meatus or the nasal midline of the patient, and the height of the zero-point adjusting support 3 is adjusted to the position. Since the air vent and the other end of the transparent hose 19 are both covered with a breathable water-blocking film, the indicating liquid can be prevented from splashing due to misoperation. In order to facilitate observation, the indicating liquid is preferably a colored liquid.
[0035] In addition, it should be noted that the zero-calibration mechanism in the embodiment 1 and the embodiment 2 of the present application can be selectively arranged, or can be arranged simultaneously.
[0036] The above description is only the preferred embodiment of the present application, and the above specific embodiments are not the limitation of the present application. Various modifications and changes can be made within the technical concept of the present application, and any modification, change or equivalent replacement made by those skilled in the art according to the above description shall fall within the scope of the present application.
