Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a measuring rack for placing a drainage tube after craniotomy. Background Art

[0002] Craniotomy is used to treat diseases such as severe craniocerebral injury and intracranial tumors. However, it is a high-difficulty and high-risk operation, and it also causes a relatively high degree of tissue damage to patients. After the operation, various drainage tubes need to be indwelled to drain intracranial blood and effusion, which plays a role in reducing intracranial pressure and clearing bloody or infected cerebrospinal fluid. Drainage tubes have different names according to the different placement positions of the catheter ends. For example, clinically common drainage tubes after craniotomy include ventricular drainage tubes, subdural drainage tubes, epidural drainage tubes, and cavity drainage.

[0003] The nursing requirements and placement height requirements of different drainage tubes are different. For example: when in the supine position, the opening of the ventricular drainage tube is required to maintain a 15-cm height difference from the ventricular plane; when in the lateral position, the opening of the ventricular drainage tube is required to be 15-18 cm higher than the mid-sagittal plane to maintain normal intracranial pressure and promote drainage; the subdural drainage tube is mainly used to drain the remaining bloody fluid or blood clots in the cyst to facilitate the bulging of the brain tissue and eliminate the dead space, and it is required that the drainage bottle is 30 cm lower than the cavity; the cavity drainage in other parts can be flush with the cavity or be nursed according to the doctor's advice.

[0004] Due to the hardness of the skull and the narrowness of the cranial cavity, whether the postoperative drainage is unobstructed directly affects the patient's life safety and prognosis survival quality. In neurosurgical nursing work, the correct nursing of the drainage tube is the key to ensuring the success of treatment and improving the prognosis quality of patients, so it is also used as one of the important nursing quality indicators to measure neurosurgery.

[0005] At present, various tools such as straight rulers and tape measures, or manual visual estimation methods are mostly used clinically to fix the height of the drainage tube, which have problems such as inconvenient use, inaccurate height of the drainage tube, and not meeting the quality control requirements or doctor's order requirements.

[0006] In addition, the height difference between the drainage tube outlet and the lateral ventricle or cavity often changes. For example, after turning over and patting the back, changing the body position, the patient returns to the ward after going out for an examination, or after transferring to another department, etc., it is necessary to re-measure and re-fix the drainage tube. The condition of patients after craniotomy is serious, and the height of the drainage tube needs to be re-adjusted after repeated going out for examinations, body position changes, and various nursing operations, which undoubtedly increases the work pressure of clinical nurses in relevant 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. Content of the Utility Model

[0014] The tail end of the first adjusting bolt is exposed outside the measuring plate. By rotating the tail end of the first adjusting bolt, the head end of the first adjusting bolt approaches or moves away from the outer surface of the rack body, so as to lock or unlock the position of the measuring plate on the rack body.

[0015] Further, the alignment part is a laser lamp arranged on the measuring plate, and the laser beam emitted by the laser lamp is perpendicular to the rack body.

[0016] The laser lamp is provided with a switch. By turning on the laser lamp and moving the position of the measuring plate, the laser beam emitted by the laser lamp can be aligned with the reference object.

[0036] By providing a measuring rack for placing a drainage tube after craniotomy in an embodiment of the present application, the technical problem in the prior art that the method for determining the placement position of the drainage tube after craniotomy is inconvenient and has low accuracy is solved.

[0037] 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 of the specification and specific implementation manners.

[0038] As Figures 1 to 4 shown, in one or more embodiments of the present application, a measuring rack for placing a drainage tube after craniotomy is provided. The measuring rack includes a rack body 10. A ventricular drainage tube hook 20, a cavity drainage tube hook 30, and a subdural drainage tube hook 50 are sequentially arranged on the rack body 10 from top to bottom. The ventricular drainage tube hook 20, the cavity drainage tube hook 30, and the subdural drainage tube hook 50 are all slidable up and down and lockably arranged on the rack body 10 to adjust the placement position on the rack body 10;

[0039] A measuring device 40 is slidable up and down and lockably arranged on the rack body 10. The measuring device 40 includes an alignment part for aligning with a reference object and a measuring part for measuring the distance relative to the alignment part, so as to respectively determine the placement positions of the ventricular drainage tube hook 20, the cavity drainage tube hook 30, and the subdural drainage tube hook 50 on the rack body 10 based on the measuring device 40.

[0040] As described above, in the embodiment of the present application, the alignment part can align with a reference object (such as the ventricular plane or the cavity of the wound), and the measuring part measures the distance relative to the alignment part to the target distance, so as to determine the placement positions of the ventricular drainage tube hook 20, the cavity drainage tube hook 30 or the subdural drainage tube hook 50 on the frame body 10. Then, by moving the ventricular drainage tube hook 20, the cavity drainage tube hook 30 or the subdural drainage tube hook 50 to the corresponding placement positions and locking them, the placement of the ventricular drainage tube hook 20, the cavity drainage tube hook 30 or the subdural drainage tube hook 50 on the frame body 10 can be realized. Since a dedicated measuring device 40 is used, not only the accuracy is relatively high, but also it is convenient to use, reducing the work pressure of clinical nurses in relevant departments, and effectively solving the technical problems of inconvenient and low-accuracy methods for determining the placement positions of drainage tubes after craniotomy in the prior art.

[0041] Specifically, the requirements for the opening of the ventricular drainage tube are as follows: when in the supine position, it should maintain a height difference of 15 cm from the ventricular plane; when in the lateral position, with the median sagittal plane as the baseline, it should be 15 - 18 cm higher. Therefore, when in the supine position, the alignment part can align with the ventricular plane, and the position where the distance measured by the measuring part relative to the alignment part is 15 cm is the placement position of the ventricular drainage tube hook 20; when in the lateral position, the alignment part can align with the median sagittal plane, and the position where the distance measured by the measuring part relative to the alignment part is 15 - 18 cm is the placement position of the ventricular drainage tube hook 20. The cavity drainage tube can be flush with the cavity of the wound. Therefore, the alignment part can align with the cavity of the wound, and the position where the distance measured by the measuring part relative to the alignment part is 0 cm is the placement position of the cavity drainage tube hook 30. The subdural drainage tube requires the drainage bottle to be 30 cm lower than the cavity of the wound. Therefore, the alignment part can align with the cavity of the wound, and the position where the distance measured by the measuring part relative to the alignment part is 30 cm is the placement position of the subdural drainage tube hook 50.

[0042] Among them, the ventricular drainage tube hook 20 is used to hang the ventricular drainage tube, the cavity drainage tube hook 30 is used to hang the cavity drainage tube, and the subdural drainage tube hook 50 is used to hang the subdural drainage tube.

[0043] In an embodiment of the present application, as Figures 1 to 4 shown, the ventricular drainage tube hook 20 and the cavity drainage tube hook 30 are respectively located above the measuring device 40, and the subdural drainage tube hook 50 is located below the measuring device 40. Since the ventricular drainage tube is required to be 15 cm above the ventricular plane, and the subdural drainage tube is required to be 30 cm below the cavity of the wound, this setting is in line with the actual usage situation.

[0044] In an embodiment of the present application, as Figures 2 to 3As shown, the measuring device 40 includes a measuring plate 41, and a first clamp 47 is fixedly provided on the back surface of the measuring plate 41. The first clamp 47 is slidably sleeved on the frame 10;

[0045] A first adjusting bolt 46 is provided on the front surface of the measuring plate 41. The head end of the first adjusting bolt 46 rotatably passes through the measuring plate 41 and penetrates into the first clamp 47, and presses the frame 10 against the inner wall of the first clamp 47, so that the measuring plate 41 is positioned on the frame 10;

[0046] The tail end of the first adjusting bolt 46 is exposed outside the measuring plate 41. By rotating the tail end of the first adjusting bolt 46, the head end of the first adjusting bolt 46 approaches or moves away from the outer surface of the frame 10, so as to lock or unlock the position of the measuring plate 41 on the frame 10.

[0047] Further, as Figures 1 to 4 shown, the alignment part is a laser lamp 42 provided on the measuring plate 41, and the laser beam emitted by the laser lamp 42 is perpendicular to the frame 10; the laser lamp 42 is provided with a switch 43. By turning on the switch 43 and moving the position of the measuring plate 41, the laser beam emitted by the laser lamp 42 can be aligned with the ventricle plane or the cavity of the wound, etc. Then, by measuring the distance with the measuring part, the placement positions of the ventricle drainage tube hook 20, the cavity of the wound drainage tube hook 30 and the subdural drainage tube hook 50 can be determined.

[0048] It can be understood that by using the laser beam to assist in aligning the reference object and avoiding alignment only by visual inspection, the measurement accuracy can be effectively improved, thereby improving the effectiveness of the measuring device 40.

[0049] Further, the measuring part includes a scale rotatably provided on the measuring plate 41, and the zero point of the scale is flush with the laser beam.

[0050] It can be understood that by measuring the distance with the scale, the placement positions of the ventricle drainage tube hook 20, the cavity of the wound drainage tube hook 30 and the subdural drainage tube hook 50 on the frame 10 can be accurately determined, thereby improving the effectiveness of the measuring device 40.

[0051] Even further, as Figures 1 to 2 shown, the scale includes a first scale 44 and a second scale 45. Among them, the measuring range of the first scale 44 is 15 cm, and the measuring range of the second scale 45 is 30 cm.

[0052] It can be understood that the placement position of the ventricular drainage tube hook 20 can be directly determined through the first scale 44, and the placement position of the subdural drainage tube hook 50 can be directly determined through the second scale 45. There is no need to excessively read the scale. It can be directly judged by the first scale 44 and the second scale 45 themselves, with high efficiency and convenient use.

[0053] Specifically, the first scale 44 and the second scale 45 are rotatably arranged on the first adjusting bolt 46. It can be understood that when the first scale 44 rotates above the measuring plate 41 for distance measurement, the second scale 45 rotates below the measuring plate 41 for distance measurement. Therefore, through holes that can be sleeved on the first adjusting bolt 46 are respectively provided at the bottom end of the first scale 44 and the top end of the second scale 45. By controlling the aperture of the through holes, the first scale 44 and the second scale 45 can not only rotate on the first adjusting bolt 46, but also maintain the relative angle with the first adjusting bolt 46 after rotating a predetermined angle.

[0054] In an embodiment of the present application, as Figures 1 to 4 shown, the ventricular drainage tube hook 20, the cavity drainage tube hook 30 and the subdural drainage tube hook 50 are respectively fixed on their respective second clamping bodies 21, 31, 51;

[0055] Each of the second clamping bodies 21, 31, 51 is slidably arranged on the frame body 10. The head ends of the second adjusting bolts 22, 32, 52 are respectively rotatably screwed into the corresponding second clamping bodies 21, 31, 51 and press the corresponding frame body 10 against the inner walls of the second clamping bodies 21, 31, 51;

[0056] The tail ends of the second adjusting bolts 22, 32, 52 are exposed outside the corresponding second clamping bodies 21, 31, 51. By rotating the tail ends of the second adjusting bolts 22, 32, 52, the head ends of the second adjusting bolts 22, 32, 52 can approach or move away from the outer surface of the corresponding frame body 10, so as to lock or unlock the positions of the ventricular drainage tube hook 20, the cavity drainage tube hook 30 or the subdural drainage tube hook 50 on the frame body 10.

[0057] In an embodiment of the present application, the bottom end of the frame body 10 is fixed to an external object through a fixing device 60.

[0058] Exemplarily, as Figures 1 to 4As shown, the fixing device includes a bedrail fixing clip 61 provided on one side of the frame body 10. The bedrail fixing clip 61 can be clamped on the bedrail. The head end of the third adjusting bolt 62 is rotatably screwed into the bedrail fixing clip 61 and presses the bedrail against the inner wall of the bedrail fixing clip 61. The tail end of the third adjusting bolt 62 is exposed outside the bedrail fixing clip 61. By rotating the tail end of the third adjusting bolt 62, the head end of the third adjusting bolt 62 can approach or move away from the bedrail, thereby clamping or loosening the bedrail.

[0059] In an embodiment of the present application, the frame body 10 is in the shape of a long rod, and the cross-sectional shape of the frame body is rectangular, so that the outer side surface of the frame body 10 is a plane.

[0060] It can be understood that the outer side surface of the frame body 10 being a plane facilitates the setting of the first adjusting bolt 46 and the second adjusting bolts 22, 32, and 52 more conveniently.

[0061] In an embodiment of the present application, a fixed hook 70 is fixedly provided on the top end of the frame body 10. It can be understood that the fixed hook 70 with a fixed setting position facilitates hanging objects with low requirements for hanging position accuracy, such as hanging an intravenous infusion bottle, etc.

[0062] An exemplary usage method of the measuring frame for placing a drainage tube after craniotomy provided by the embodiment of the present application is as follows:

[0063] First step, fix the bedrail fixing clip 61 on the measuring frame to the bedrail and get as close as possible to the cranial part.

[0064] Second step, raise the head of the patient's bed (if there are no contraindications, raise the head of the bed by 30°), and rotate the first adjusting bolt 46 to turn on the laser lamp 42.

[0065] Third step, make the laser beam of the laser lamp 42 level with the position of the lateral ventricle. Rotate the first scale 44 upwards by 15 cm so that the position of the drainage tube is 15 cm higher than the plane of the lateral ventricle. Adjust the second adjusting bolt 22 of the ventricular drainage fluid hook so that the position of the ventricular drainage fluid hook is flush with the end of the first scale 44, fix the ventricular drainage fluid hook on the frame body 10, and hang the ventricular drainage tube on the ventricular drainage fluid hook.

[0066] Fourth step, turn on the laser lamp 42 to make the laser beam of the laser lamp 42 level with the position of the wound cavity. Adjust the second adjusting bolt 32 of the wound cavity drainage tube hook so that the wound cavity drainage tube hook 30 is flush with the end of the laser, fix the wound cavity drainage tube hook 30 on the frame body 10, and hang the wound cavity drainage tube on the wound cavity drainage tube hook 30.

[0067] Step 5: Turn on the laser lamp 42 to make the laser beam of the laser lamp 42 level with the position of the creation cavity. Rotate the second scale 45 with a length of 30 cm downward, and adjust the second adjustment bolt 52 of the subdural drainage tube hook 50 to make the subdural drainage tube hook 50 level with the end of the second scale 45. Then fix the subdural drainage tube hook 50 on the frame body 10, and hang the subdural drainage tube on the subdural drainage tube hook 50.

[0068] It should be understood that although the quantitative terms "first", "second", etc. may be used herein to describe various units, these units should not be limited by these terms. These terms are only used to distinguish one unit from another. For example, without departing from the scope of the exemplary embodiments, the first unit may be referred to as the second unit, and similarly, the second unit may be referred to as the first unit.
