Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of medical devices, in particular to a device for measuring the placement height of a drainage tube after craniotomy. Background Art
[0002] Craniotomy is used to treat severe craniocerebral injuries, intracranial tumors and other diseases, but it is a high-difficulty and high-risk operation, and it also causes a high degree of tissue damage to the patient. After surgery, various drainage tubes need to be left in place to drain blood and fluid in the brain, which can reduce intracranial pressure and clear bloody or infected cerebrospinal fluid. Drainage tubes have different names depending on the placement of the end of the catheter. For example, common drainage tubes after craniotomy in clinical practice include ventricular drainage tubes, subdural drainage tubes, epidural drainage tubes, and wound cavity drainage.
[0003] Different drainage tubes have different nursing requirements and placement height requirements. For example, in the supine position, the opening of the ventricular drainage tube is required to maintain a height difference of 15 cm with the ventricular plane. In the lateral position, the opening of the ventricular drainage tube is required to be 15 to 18 cm higher than the mid-sagittal plane to maintain normal intracranial pressure and promote drainage. Subdural drainage tubes are mainly used to empty the bloody fluid or blood clots remaining in the sac to facilitate brain tissue expansion and eliminate dead space. The drainage bottle is required to be 30 cm lower than the wound cavity. Wound drainage in other parts of the body can be kept flush with the wound cavity or cared for as directed by the doctor.
[0004] Because the skull is hard and the cranial cavity is narrow, whether the drainage is smooth after surgery directly affects the patient's life safety and prognosis quality of life. In neurosurgery nursing work, the correct care of the drainage tube is the key to ensuring the success of treatment and improving the quality of patient prognosis, so it is also regarded as one of the important nursing quality indicators for measuring neurosurgery.
[0005] At present, various tools such as rulers and tape measures, or manual visual estimation are often used to fix the height of the drainage tube in clinical practice. This has the disadvantages of being inconvenient to use, inaccurate height of the drainage tube, and not meeting quality control requirements or medical advice requirements.
[0006] In addition, the height difference between the drainage tube outlet and the lateral ventricle or wound cavity often changes, such as turning over and patting the back, changing body position, returning to the ward after an outpatient checkup, or transferring to another department, which all require re-measurement and re-fixation of the drainage tube. After craniotomy, the patient's condition is serious, and the height of the drainage tube needs to be readjusted after repeated outpatient checkups, changes in body position, and various nursing operations, which undoubtedly increases the work pressure of clinical nurses in related departments.
[0007] Therefore, the above-mentioned prior art has at least the following technical problems: the method for determining the placement position of the drainage tube after craniotomy in the prior art is inconvenient and has low accuracy. Utility Model Content
[0008] The embodiment of the present application solves the technical problem that the method for determining the placement position of the drainage tube after craniotomy in the prior art is inconvenient and has low accuracy by providing a device for measuring the height of the drainage tube after craniotomy.

[0011] A scale, the inner end of which is rotatably disposed on the left end of the sliding plate, the scale being provided with scales for measuring distance, and the scales extending from the inner end of the scale to the outer end of the scale;
[0012] During the process of the scale rotating relative to the sliding plate, the scale has a first position, a second position and a third position; when the scale is at the first position, the scale is perpendicular to the sliding plate, and the scale is located above the sliding plate; when the scale is at the second position, the scale is collinear with the sliding plate; when the scale is at the third position, the scale is perpendicular to the sliding plate, and the scale is located below the sliding plate.
[0013] Furthermore, the scale can be slid left and right on the sliding plate.
[0014] Furthermore, the sliding plate is provided with a sliding groove extending in the left-right direction, a rotating shaft is slidably provided in the sliding groove, and the scale is rotatably arranged on one end of the rotating shaft.
[0015] Furthermore, a plug is provided on the other end of the rotating shaft to prevent the rotating shaft from slipping out of the sliding groove.
[0016] Furthermore, the slide groove is a waist groove.
[0017] Furthermore, the sliding plate is provided with an indication structure for aligning the reference object, and the indication structure is flush with the zero point of the scale.
[0018] Further, the indicating structure is an arrow arranged on the right end of the sliding plate.
[0019] Furthermore, the measuring range of the scale is 30 cm.
[0020] Furthermore, the length of the sliding plate along the left-right direction is 25 to 30 cm.
[0021] Furthermore, the length of the slide groove along the left-right direction is 15 to 20 cm.
[0022] One or more technical solutions provided in the embodiments of the present application have at least the following technical effects or advantages:
[0023] By setting the sliding plate to align with a reference object (such as the ventricular plane or the wound cavity) and setting a ruler to measure the distance relative to the sliding plate, the placement position of the drainage tube after craniotomy can be determined. Since the sliding plate is used for alignment, alignment by visual inspection alone is avoided, and a ruler integrated with the sliding plate is set for distance measurement, the accuracy of distance measurement and the convenience and efficiency of determining the placement position of the drainage tube can be effectively improved, thereby reducing the workload of clinical nurses in related departments.

[0032] The embodiment of the present application solves the technical problem that the method for determining the placement position of the drainage tube after craniotomy in the prior art is inconvenient and has low accuracy by providing a device for measuring the height of the drainage tube after craniotomy.
[0033] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.
[0034] like Figures 1 to 4 As shown, one or more embodiments of the present application provide a device for measuring the placement height of a drainage tube after craniotomy, the measuring device comprising:
[0035] A sliding plate 10 extending left and right, and the sliding plate 10 is used to align a reference object;
[0036] A scale 20, the inner end of which is rotatably disposed on the left end of the sliding plate 10, the scale 20 being provided with scales for measuring distance, and the scales extending from the inner end of the scale 20 to the outer end of the scale 20;
[0037] During the rotation of the scale 20 relative to the sliding plate 10, the scale 20 has a first position, a second position and a third position. When the scale 20 is at the first position, the scale 20 is perpendicular to the sliding plate 10, and the scale 20 is located above the sliding plate 10; when the scale 20 is at the second position, the scale 20 is collinear with the sliding plate 10; when the scale 20 is at the third position, the scale 20 is perpendicular to the sliding plate 10, and the scale 20 is located below the sliding plate 10.
[0038] From the above description, it can be known that the embodiment of the present application sets the sliding plate 10 to align with the reference object (such as the ventricular plane or the wound cavity), and sets the scale 20 to measure the distance relative to the sliding plate 10, so as to determine the placement position of the drainage tube after craniotomy. Since the sliding plate 10 is used for alignment, alignment only by visual inspection is avoided, and a scale 20 integrated with the sliding plate 10 is set for distance measurement, which can effectively improve the accuracy of distance measurement and the convenience and efficiency of determining the placement position of the drainage tube, thereby reducing the workload of clinical nurses in related departments.
[0039] In addition, since the scale 20 can rotate relative to the sliding plate 10, the relative position between the scale 20 and the sliding plate 10 can be adjusted to meet various measurement modes, thereby realizing the position determination of various drainage tubes, which is very practical.
[0040] For example, the requirements for the opening of the ventricular drainage tube are: when lying on the back, the height difference with the ventricular plane is maintained at 15 cm, and when lying on the side, the height difference is 15 to 18 cm higher than the midsagittal plane. Figure 1 As shown, in the supine position, align the sliding plate 10 with the ventricular plane, and then measure the distance of 15 cm relative to the sliding plate 10 by the ruler 20, which is the placement position of the ventricular drainage tube; in the lateral position, align the sliding plate 10 with the midsagittal plane, and measure the distance of 15 to 18 cm relative to the sliding plate 10 by the ruler 20, which is the placement position of the ventricular drainage tube.
[0041] For another example, the requirement for the opening of the wound cavity drainage tube is to keep it flush with the wound cavity. Therefore, the scale 20 is rotated to the second position, such as Figure 2 Or as shown in FIG. 3 , align the sliding plate 10 with the wound cavity, and the position of the wound cavity drainage tube is located at the position parallel to the wound cavity (or the sliding plate 10 and the scale 20 ).
[0042] For example, the subdural drainage tube opening requirement is: 30 cm below the wound cavity, therefore, the scale 20 is rotated to the third position, such as Figure 4 As shown, the sliding plate 10 is aligned with the wound cavity, and the position of the subdural drainage tube is measured by a ruler 20 to be 30 cm below the sliding plate 10 .
[0043] In summary, the embodiments of the present application effectively solve the technical problem in the prior art that the method for determining the placement of the drainage tube after craniotomy is inconvenient and has low accuracy.
[0044] It should be noted that, in the embodiment of the present application, the scale 20 can rotate 360° relative to the sliding plate 10 .
[0045] It is to be understood that, in the various embodiments of the present application, if terms indicating orientation or positional relationship such as "top", "bottom", "up", "down", "high", "low", "inside", "outside" etc. appear, they are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present application.
[0046] In one embodiment of the present application, Figures 1 to 4As shown, the sliding plate 10 is provided with an indication structure 12 for aligning a reference object, and the indication structure 12 is flush with the zero point of the scale 20 .
[0047] Specifically, by arranging the indicating structure 12 to align with the reference object, the accuracy of height measurement can be further improved. The scale 21 gradually increases from the inner end to the outer end of the scale 20 , and the zero point of the scale 20 is located at the innermost end of the scale 20 .
[0048] For example, Figures 1 to 4 As shown, the indicating structure 12 is an arrow disposed on the right end of the sliding plate 10. Of course, the indicating structure 12 can also be a protrusion, a convex point, a groove, a line or the like, as long as it can play an alignment role, and is not limited here.
[0049] In one embodiment of the present application, the measuring range of the scale 20 is 30 cm.
[0050] It can be understood that the drainage tube after craniotomy mainly refers to the ventricular drainage tube, the wound cavity drainage tube and the subdural drainage tube, and the distance between them and their respective reference objects is 15 to 30 cm. Therefore, setting the measuring range of the scale 20 to 30 cm can meet specific needs and avoid affecting other operations due to the excessive length of the scale 20.
[0051] In an embodiment of the present application, the scale 20 is slidably disposed on the sliding plate 10 .
[0052] It can be understood that the scale 20 can be moved left and right on the sliding plate 10, so that the position of the scale 20 on the sliding plate 10 can be adjusted to adapt to various usage scenarios. For example, when the drainage tube is located on the right and the wound is located on the left, the scale 20 needs to be slid to the left end; conversely, when the drainage tube is located on the left and the wound is located on the right, the scale 20 needs to be slid to the right end.
[0053] Further, such as Figures 1 to 4 As shown, the sliding plate 10 is provided with a slide groove 11 extending in the left-right direction, a rotating shaft is slidably provided in the slide groove 11, and the scale 20 is rotatably arranged on one end of the rotating shaft. In this way, the scale 20 can be rotated relative to the sliding plate 10, and can also be moved on the sliding plate 10, meeting actual needs.
[0054] In one embodiment of the present application, Figures 1 to 4 As shown, a plug 30 is provided on the other end of the rotating shaft to prevent the rotating shaft from slipping out of the sliding groove 11, so as to improve the effectiveness of the measuring device.
[0055] For example, Figures 1 to 4 As shown, the slide groove 11 is a waist groove. Specifically, the smooth curve of the waist groove can reduce stress concentration points and reduce wear when contacting the rotating shaft, thereby extending the service life and making the scale 20 smoother when moving.
[0056] In an embodiment of the present application, the length of the sliding plate 10 along the left-right direction is 25 to 30 cm, and the length of the sliding groove 11 along the left-right direction is 15 to 20 cm.
[0057] Specifically, the above dimensions are suitable for actual clinical occasions, can meet specific needs, and are practical.
[0058] An exemplary method of using the device for measuring the height of drainage tube placement after craniotomy provided in the embodiment of the present application is as follows:
[0059] Step 1: Make the indicating structure 12 on the sliding plate 10 level with the position of the lateral ventricle, rotate the scale 20, and rotate the scale 20 to form an angle of 90° with the sliding plate 10, that is, the scale 20 is located at the first position, such as Figure 1 Slide the scale 20 left and right to adapt to the position of the hook for hanging the ventricular drainage tube; hang the ventricular drainage bag corresponding to 15cm on the scale 20 and connect the ventricular drainage tube.
[0060] Step 2: Make the indicating structure 12 on the sliding plate 10 level with the wound cavity; rotate the scale 20 until it forms an angle of 0° or 180° with the sliding plate 10, i.e. the scale 20 is at the second position, such as Figure 2 Or as shown in 3; hang the wound cavity drainage bag horizontally at the wound cavity position and connect the wound cavity drainage tube.
[0061] Step 3: Make the indicating structure 12 on the sliding plate 10 level with the wound cavity; rotate the scale 20 until it forms a 90° angle with the sliding plate 10, i.e. the scale 20 is located at the third position, such as Figure 4 As shown; slide the scale 20 left and right to adapt to the position of the hook for hanging the subdural drainage tube; hang the subdural drainage bag 30cm below the corresponding scale 20 and connect the subdural drainage tube.
[0062] It should be understood that although the terms "first", "second", etc. may be used herein to describe various units, these units should not be limited by these terms. These terms are used only to distinguish one unit from another. For example, a first unit may be referred to as a second unit, and similarly, a second unit may be referred to as a first unit without departing from the scope of the exemplary embodiments.

They are relative concepts and may change accordingly according to different positions and different usage conditions. Therefore, these or other directional terms should not be interpreted as restrictive terms.
