Abstract
Description
TECHNICAL FIELD
[0001] The present application relates to the technical field of body fluid delivery, in particular to a ventricular drainage device measurement fixing device. BACKGROUND
[0002] Reference Figure 1 A common ventricular drainage device or ventricular drainage system is composed of at least a drainage pipeline 1, a drip bottle (ventricular drainage bottle) 2, and a collection container 3. An intracranial pressure scale should also be provided for the cerebrospinal fluid ventricular puncture external drainage collection device. According to the reference "Chinese Expert Consensus on External Cerebrospinal Fluid Drainage in Neurosurgery (2018 Edition) [J]. Chinese Journal of Medicine, 2018, 98(21): 1646-1649.", when performing ventricular drainage, the ventricular drainage bottle should be hung on the bedside, and the highest point of the drainage pipeline (located in the ventricular drainage bottle) should be 10-15 cm higher than the lateral ventricle plane. The daily cerebrospinal fluid drainage is generally not more than 500 ml (normal people secrete 400-500 ml / d), and most of the time, the drainage volume is controlled at about 200 ml per day, and the average drainage speed is <5-20 ml / h. The inventor found in the actual work process that because the conditions and physical conditions of each patient are different, medical staff will adjust the height of the ventricular drainage bottle according to the doctor's instructions. When adjusting, it is generally measured in centimeters. In order to ensure accuracy, a transparent scale is often used for measurement. This process requires a lot of time, and it is difficult to avoid errors due to visual measurement. CONTENT OF THE UTILITY MODEL
[0003] The main purpose of the present application is to provide a ventricular drainage device measurement fixing device capable of quickly and accurately adjusting the drainage height. To this end, the present application provides the following technical solution:
[0004] A ventricular drainage device measurement fixing device, comprising a hanging ruler and a clamping seat;
[0005] The hanging ruler comprises a strip plate and a tube clamp. The front surface of the strip plate is provided with a plurality of clamping holes arranged in a row along the length direction, and is provided with a scale capable of displaying the height of the clamping holes. The tube clamp is arranged on the back surface of the strip plate and can be clamped on the infusion support;
[0006] The clamping seat comprises a back plate and a bottle clamp. The bottle clamp is arranged on the front surface of the back plate and is used for clamping the ventricular drainage bottle. The back surface of the back plate is provided with a buckle which is detachably connected to the clamping hole.
[0007] In at least one embodiment, the clamping holes are equally spaced, and the distance between the lower edges of two adjacent clamping holes is 1 cm.
[0008] In at least one embodiment, the tube clamp and the bottle clamp are both claw-shaped and have elasticity. The tube clamp and the bottle clamp are both provided with two.
[0009] In at least one embodiment, at least one of the pipe clamps is threaded with a screw, the head of which is located on the outside of the pipe clamp and the tip extends to the inside of the pipe clamp.
[0010] In at least one embodiment, at least one of the bottle clamps is provided with a bolt, the open end of the bottle clamp being two parallel flat plates, and the bolt being threaded between the two flat plates.

[0020] The application will be described in detail below with reference to the exemplary embodiments in the drawings. It should be understood that the application can be realized in many different forms and should not be construed as being limited to the embodiments set forth herein. These embodiments are provided so that the disclosure of the application is complete and fully communicates the concept of the application to those skilled in the art.
[0021] In the description of the application, it should be understood that the terms "center", "transverse", "longitudinal", "front", "back", "left", "right", "up", "down", "vertical", "horizontal", "top", "bottom", "inner", "outer", and the like indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only for the purpose of facilitating the description of the application and simplifying the description, and do not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as limiting the scope of protection of the application.
[0022] As shown in Figures 2 to 4 The ventricular drain measuring device of Embodiment 1 includes a hanging ruler 4 and a clamping seat 5. The hanging ruler 4 includes a strip plate 41 and a tube clamp 42. The front surface of the strip plate 41 is provided with a plurality of clamping holes 43 arranged in a row along the length direction, and is provided with a scale 44 capable of displaying the height of the clamping holes 43. The tube clamp 42 is arranged on the back surface of the strip plate 41 and can be clamped on an infusion support. The clamping seat 5 includes a back plate 51 and a bottle clamp 52. The bottle clamp 52 is arranged on the front surface of the back plate 51 and is used to clamp the ventricular drainage bottle 2. The back surface of the back plate 51 is provided with a buckle 53 which is detachably clamped on the clamping hole 43.
[0023] The hanging ruler 4 and the clamping seat 5 can be made of ABS plastic, which can ensure the overall toughness and also give the buckle 53, the tube clamp 42 and the bottle clamp 52 a certain elasticity. The clamping holes 43 are equally spaced, and the distance between the lower edges of the two adjacent clamping holes 43 is 1 cm. In this way, the actual use condition of adjusting in centimeters as the basic adjustment unit can be adapted. The tube clamp 42 and the bottle clamp 52 should have different sizes according to the objects they need to clamp. In this embodiment, the tube clamp 42 and the bottle clamp 52 are both in the shape of a ring and are provided with two claws.
[0024] Snap-fit or latching connections are conventional connection methods in this field, and their specific forms vary. Commonly, plastic snap-fit connections are used, primarily utilizing the property that plastic can return to its original shape after elastic deformation, thus enabling quick and detachable connections. Without limitation, this embodiment provides a reference structure where the back of the strip 41 has a groove 46, the bottom of which connects to all the latches 43; the latch 53 is an elastically deformable cantilever with a protruding front end. When the latch 53 is engaged, its protruding front end passes through the latch 43 and hooks onto the edge of the latch 43 within the groove 46. Figure 4 As shown, the front protrusion of the latch 53 has a smoothly transitioned flat surface to facilitate insertion and removal.
[0025] Of course, the snap-fit method can also have other structures. For example, the buckle 53 can be set to be thicker than the width of the slot 43 and narrower than the width of the slot 43. When in use, it is first inserted horizontally into the slot 43, and then rotated 90° so that the buckle 53 is tightly snapped into the slot 43.
[0026] When in use, the highest point of drainage in the ventricle drainage bottle 2 should have a reference line, such as being at the same level as the buckle 53, or the upper edge of the back plate 51 (the upper edge should be an integer multiple of 1 cm from the buckle 53). Then, by inserting or removing the buckle 53 according to the scale, the highest point of drainage of the entire drainage system can be adjusted.
[0027] like Figure 5 As shown in the figure, this embodiment illustrates Embodiment 2 of the present application. The main difference between this embodiment and Embodiment 1 is that a fastening method has been added.
[0028] Specifically, a screw 45 is threaded onto one of the tube clamps 42, with the head of the screw 45 located on the outside of the tube clamp 42 and the tip penetrating to the inside of the tube clamp 42. A bolt 54 is provided on one of the bottle clamps 52, the open end of which consists of two parallel flat plates 55, and the bolt 54 is threaded between the two flat plates 55. By adding the screw 45, the tube clamp 42 can be more securely fixed to the infusion stand; by adding the bolt 54, the ventricle drainage bottle can be more securely fixed to the holder 5.
[0029] It should be understood that all the above embodiments are exemplary and not restrictive. Various modifications or variations made by those skilled in the art to the specific embodiments described above under the concept of this application should be within the protection scope of this application.
