Description

Technical Field

[0001] The utility model relates to the technical field of medical devices for drainage, and more specifically, to a drainage system capable of accurately positioning a drainage drip bottle. Background Art

[0002] A cranial pressure monitoring and regulating device usually includes a scale and a drainage drip bottle. The drainage drip bottle is fixed on a sliding block and slides on the scale through the sliding block. The drainage drip bottle includes a liquid inlet and a liquid outlet, and a liquid inlet marking line is provided on the bottle body corresponding to the position of the liquid inlet. The "0" on the scale corresponds to the reference scale line. Before drainage, the reference scale line is adjusted to be at the same height as the "zero point" position of the intracranial pressure in the patient's body (the external auditory canal when lying supine). When the liquid flow rate at the liquid inlet pipe is close to 0, the reading corresponding to the liquid inlet marking line is the intracranial pressure of the patient at this time. Therefore, the positioning accuracy of the drainage drip bottle directly affects the reading accuracy of the intracranial pressure, and the position positioning of the drainage drip bottle on the sliding block is extremely important.

[0003] Chinese patents such as Chinese Patent CN220860444U, CN219185163U, CN220801588U, etc. have all disclosed a drainage bottle for cranial drainage. The outer surfaces of the bottle bodies of these drainage bottles are regular, and no corresponding positioning structure is provided for the positioning and fixing of the drainage bottle. When fixing this type of drainage bottle, it depends on visual observation and alignment, with many accidental factors, high requirements for operators, inconvenient use, and affecting the accuracy of intracranial pressure readings, thus having an adverse effect on the treatment effect. Summary of the Utility Model

[0004] The purpose of the utility model is to overcome the deficiencies in the prior art and provide a drainage system capable of accurately positioning a drainage drip bottle, which can effectively, accurately and quickly position the position of the drainage drip bottle and help accurately read the intracranial pressure reading.

[0005] To solve the above technical problems, the technical solution adopted by the utility model is:

[0006] Provide a drainage system capable of accurately positioning a drainage drip bottle, including a drainage drip bottle and a fixing device. The fixing device includes a positioning block, and the drainage drip bottle is installed on the fixing device and the top surface of the drainage drip bottle is in contact with the lower surface of the positioning block.

[0007] The drainage system capable of accurately positioning the drainage drip bottle of the present utility model. When the top surface of the drainage drip bottle contacts the lower surface of the positioning block, the uppermost installation position of the drainage drip bottle relative to the fixing device can be determined, and no upward relative displacement will occur. Then, the drainage drip bottle is fixed at this installation position through the fixing device, and the accurate positioning of the drainage drip bottle can be achieved. The drainage system capable of accurately positioning the drainage drip bottle of the present utility model effectively, accurately and quickly positions the position of the drainage drip bottle, which helps to accurately read the intracranial pressure reading.

[0008] Further, the fixing device includes a clamping assembly, and the drainage drip bottle is clamped by the clamping assembly. The clamping assembly is used for fixing the drainage drip bottle, with simple operation and stable clamping.

[0009] Further, the drainage drip bottle includes a bottle body and a positioning platform provided on the outer periphery of the bottle body. The positioning platform abuts against the clamping assembly and the bottom surface of the positioning platform and the upper surface of the clamping assembly are in the same plane. This positioning platform can be located at different heights of the drainage drip bottle. The bottom surface of the positioning platform and the upper surface of the clamping assembly are in the same plane, which can determine the lowermost installation position of the drainage drip bottle relative to the fixing device, and no downward relative displacement will occur. Cooperating with the contact between the top surface of the drainage drip bottle and the lower surface of the positioning block, the positioning of the drainage drip bottle in the up and down directions is realized, which is more accurate.

[0010] Further, the positioning platform abuts against the positioning block and the upper surface of the positioning platform and the lower surface of the positioning block are in the same plane. At this time, the top surface of the positioning platform and the top surface of the drainage drip bottle are in the same plane.

[0011] Further, the positioning platform is an ear-shaped structure for fixing the liquid inlet pipe, and the ear-shaped structure is provided on the outer periphery of the bottle body. This positioning platform not only plays a positioning role but also can play a role in fixing the liquid inlet pipe.

[0012] Further, the positioning platform is an annular structure surrounding the outer periphery of the bottle body. This annular structure can specifically be a cover detachably connected to the bottle body, and the diameter of the cover is larger than the diameter of the bottle body, so as to form a positioning step at the connection between the cover and the bottle body.

[0013] Further, the clamping assembly includes a first elastic claw and a second elastic claw symmetrically arranged. A clamping space for clamping the drainage drip bottle is formed between the first elastic claw and the second elastic claw. The first elastic claw and the second elastic claw form a tightening ring, and the drainage drip bottle can be quickly clamped and fixed within the tightening ring.

[0014] Further, a liquid inlet and an air inlet are provided at the top of the drainage drip bottle, and the outer peripheries of the liquid inlet and the air inlet are both abutted against the side surface of the positioning block. When the drainage drip bottle is fixedly positioned in the fixing device, the outer peripheries of the liquid inlet and the air inlet are both abutted against the side surface of the positioning block, so that the drainage drip bottle can be effectively prevented from rotating, and when the drainage drip bottle is fixedly positioned, the liquid inlet marking line and the scale marking are just facing the user.

[0015] Further, the fixing device further includes a connecting plate, the positioning block is connected to the connecting plate, at least one side of the connecting plate is provided with a triangular scale indicating block, and a liquid inlet marking line is provided circumferentially on the drainage drip bottle. When the drainage drip bottle abuts and positions with the positioning block, the tip of the scale indicating block is located at the cross section where the liquid inlet marking line is located. After the drainage drip bottle is fixedly positioned by the fixing device, its liquid inlet marking line is exactly at the same horizontal plane as the tip of the scale indicating block, so that the current intracranial pressure value of the patient can be directly obtained by reading the pointing of the tip of the scale indicating block.

[0016] Further, a scale is also included, and the fixing device is slidably connected to the scale. After the drainage drip bottle is installed, the fixing device is slid on the scale to drive the drainage drip bottle to move and adjust the height of the drainage drip bottle to control the drainage speed. When the liquid flow rate at the liquid inlet of the drainage drip bottle is close to 0, the reading corresponding to the liquid inlet marking line or the scale line corresponding to the scale indicating block is the intracranial pressure of the patient at this time.

[0017] Compared with the prior art, the beneficial effects of the present utility model are:

[0018] The drainage system of the present utility model that can achieve accurate positioning of the drainage drip bottle restricts the movement of the drainage drip bottle, effectively, accurately and quickly positions the position of the drainage drip bottle, helps to accurately read the intracranial pressure reading, and thus helps to control the treatment effect.

[0026] Embodiment 1

[0027] This embodiment is the first embodiment of a drainage system that can accurately position the drainage drip bottle 100, including the drainage drip bottle 100 and a fixing device 200. The fixing device 200 includes a positioning block 230. The drainage drip bottle 100 is installed on the fixing device 200, and the top surface of the drainage drip bottle 100 is in contact with the lower surface of the positioning block 230.

[0028] Specifically, in this embodiment, the top surface of the drainage drip bottle 100 serves as the first positioning plane 151. The first positioning plane 151 intersects with the axis of the drainage drip bottle 100, such as Figure 1As shown in the figure. The first positioning plane 151 intersects with the axis of the drainage drip bottle 100 instead of being parallel. The positioning block 230 on the fixing device 200 abuts against the first positioning plane 151, so as to determine the installation position of the drainage drip bottle 100 relative to the uppermost end of the fixing device 200, and no upward relative displacement will occur. Then, the drainage drip bottle 100 is fixed at this installation position through the fixing device 200, and the accurate positioning of the drainage drip bottle 100 can be realized. The intersection in this embodiment means that an included angle is formed between the first positioning plane 151 and the axis of the drainage drip bottle 100, and the two are not parallel. When the first positioning plane 151 is perpendicular to the axis of the drainage drip bottle 100, the best positioning effect can be obtained.

[0029] Among them, in this embodiment, as Figure 2 shown, the drainage drip bottle 100 includes a bottle body 110, and a liquid inlet 120 and a liquid outlet 130 provided at both ends of the bottle body 110. An air inlet 140 communicated with the bottle body 110 is provided beside the liquid inlet 120. The setting of the air inlet 140 can maintain the pressure balance when the drainage liquid enters and exits the drainage drip bottle 100, and avoid the siphon phenomenon. The drainage liquid enters the bottle body 110 through the liquid inlet 120 and flows out of the bottle body 110 through the liquid outlet 130. In order to ensure the cleanliness of the air entering the bottle body 110 through the air inlet 140, in this embodiment, an air filter is provided at the air inlet 140; in order to facilitate the installation and replacement of the air filter, the air filter can be detachably connected to the air inlet 140 in this embodiment.

[0030] A liquid inlet marking line 160 is provided on the circumferential direction of the bottle body 110, and a scale marking 170 is provided below the liquid inlet marking line 160. The scale marking 170 is specifically a volume marking. Among them, the liquid inlet marking line 160 is specifically a double-headed arrow, and the plane where the double-headed arrow is located is perpendicular to the axis of the drainage drip bottle 100. There are often two scales on the scale ruler 400 in the drainage system, one is the water column scale and the other is the mercury column scale. The two arrows of the double-headed arrow respectively point to the water column scale and the mercury column scale; when there is only one scale, the liquid inlet marking line 160 can be set as a single-headed arrow pointing to this scale. When the liquid flow rate at the liquid inlet 120 of the drainage drip bottle 100 is close to 0, the reading corresponding to its liquid inlet marking line 160 is the intracranial pressure of the patient at this time; the scale marking 170 is used to read the volume of the liquid in the drainage drip bottle 100.

[0031] In addition, in this embodiment, as Figure 3As shown, the fixing device 200 includes a connecting plate 210, a clamping assembly 220 and a positioning block 230. The clamping assembly 220 and the positioning block 230 are both arranged on the connecting plate 210. Specifically, the clamping assembly 220 includes a first elastic claw 221 and a second elastic claw 222 symmetrically arranged on the connecting plate 210. A clamping space for clamping the drainage drip bottle 100 is formed between the first elastic claw 221 and the second elastic claw 222. The first elastic claw 221 and the second elastic claw 222 form a clamping ring, and the drainage drip bottle 100 can be quickly clamped and fixed within the clamping ring. The diameter of the clamping ring should be equal to or slightly smaller than the diameter of the drainage drip bottle 100 to ensure the stability of clamping. It should be noted that the clamping assembly 220 formed by the first elastic claw 221 and the second elastic claw 222 is not a limitation of the present utility model, and any other clamping mechanism that can clamp and limit the movement of the drainage drip bottle 100 in two opposite directions can be applied to the present utility model.

[0032] In this embodiment, the first positioning plane 151 and the top surface of the drainage drip bottle 100 are in the same plane, and the top surface of the drainage drip bottle 100 is in contact with the lower surface of the positioning block 230. The first positioning plane 151 is perpendicular to the axis of the drainage drip bottle 100, and the axial height of the drainage drip bottle 100 can be simply, effectively and accurately positioned.

[0033] In the existing craniocerebral pressure monitoring and regulating device, only by visually judging the alignment position of the liquid inlet marking line 160 and the scale line for reading, it is easy to produce errors, resulting in inaccurate reading, and the reading judgment is time-consuming and laborious. In order to conveniently read the intracranial pressure value, in this embodiment, at least one side of the connecting plate 210 is provided with a triangular scale indicating block 240. When the drainage drip bottle 100 is positioned and fixed, the tip of the scale indicating block 240 is located in the cross-section where the liquid inlet marking line 160 is located. When the drainage drip bottle 100 is fixed and positioned by the fixing device 200, its liquid inlet marking line 160 is exactly in the same horizontal plane as the tip of the scale indicating block 240, so that the intracranial pressure value of the patient at the moment can be directly obtained by reading the direction pointed by the tip of the scale indicating block 240.

[0034] For the convenience of reading the intracranial pressure value, this embodiment further includes a scale 400. The fixing device 200 is slidably connected to the scale 400, as Figure 4As shown. After the drainage dropper 100 is installed, the fixing device 200 is slid on the scale 400 to drive the drainage dropper 100 to move and adjust the height of the drainage dropper 100 to control the drainage speed. When the liquid flow rate of the liquid inlet 120 of the drainage dropper 100 is close to 0, the reading corresponding to the liquid inlet mark line 160 or the scale line corresponding to the scale indicator block 240 is the intracranial pressure of the patient at this time. In this embodiment, the fixing device 200 can be directly slidably connected to the scale 400, or it can be slidably connected to the scale 400 through the sliding block 300. Specifically, the drainage dropper 100 is installed on the clamping assembly 220, the connecting plate 210 is provided on the sliding block 300, and the sliding block 300 is slidably connected to the scale 400.

[0035] There are often two scales on the scale 400 in the drainage system, one is the water column scale and the other is the mercury column scale. In this case, the scale indicator blocks 240 are in two groups, which are respectively arranged on both sides of the connecting plate 210, and the tips of the two groups of scale indicator blocks 240 point to the water column scale and the mercury column scale respectively; when there is only one scale, the scale indicator blocks 240 are in one group, which are arranged on the side of the connecting plate 210 close to the scale of the scale 400, and the tips of the scale indicator blocks 240 point to the scale. When the liquid flow rate of the liquid inlet 120 of the drainage dropper bottle 100 is close to 0, the reading corresponding to the liquid inlet mark line 160 (i.e., the scale line corresponding to the scale indicator block 240) is the intracranial pressure of the patient at this time, and the reading is convenient, fast and accurate.

[0036] When the utility model is implemented, the drainage drip bottle 100 is first installed and positioned, the first elastic claw 221 and the second elastic claw 222 are opened, and the drainage drip bottle 100 is placed in the clamping space, and the position of the drainage drip bottle 100 is adjusted to the top surface of the drainage drip bottle 100 and the bottom surface of the positioning block 230, and the outer peripheral surface of the bottle body 110 and the side surface of the connecting plate 210 are in contact, so as to complete the positioning and fixation of the drainage drip bottle 100; after the drainage drip bottle 100 is installed, the sliding block 300 is slid on the scale 400 to drive the drainage drip bottle 100 to move and adjust the height of the drainage drip bottle 100 to control the drainage speed. When the liquid flow rate of the liquid inlet 120 of the drainage drip bottle 100 is close to 0, the reading corresponding to the liquid inlet mark line 160 or the scale line corresponding to the scale indicator block 240 is the patient's intracranial pressure at this time.

[0037] Embodiment 2

[0038] This embodiment is the second embodiment of the drainage system that can achieve accurate positioning of the drainage drip bottle 100. This embodiment is similar to the first embodiment. The difference is that the drainage drip bottle 100 includes a bottle body 110 and a positioning platform 150 provided on the outer periphery of the bottle body 110. The positioning platform 150 abuts against the clamping assembly 220, and the bottom surface of the positioning platform 150 and the upper surface of the clamping assembly 220 are located on the same plane, determining the lowest installation position of the drainage drip bottle 100 relative to the fixing device 200, and no downward relative displacement occurs. Combining with the contact between the top surface of the drainage drip bottle 100 and the lower surface of the positioning block 230, the positioning of the drainage drip bottle 100 in the up and down directions is realized, which is more accurate.

[0039] In order to achieve the simultaneous positioning of the top surface and the bottom surface of the positioning platform 150 to maintain the accuracy and stability of the positioning of the drainage drip bottle 100, in this embodiment, the positioning platform 150 abuts against the positioning block 230, and the upper surface of the positioning platform 150 and the lower surface of the positioning block 230 are located on the same plane. At this time, the upper surface of the positioning platform 150, the lower surface of the positioning block 230, the top surface of the drainage drip bottle 100, and the first positioning plane 151 are all on the same plane. The upper surface of the positioning platform 150 and the top surface of the drainage drip bottle 100 jointly abut against and limit the lower surface of the positioning block 230, which can increase the contact area between the two and improve the stability of the positioning of the drainage drip bottle.

[0040] The top surface of the positioning platform 150 is the first positioning plane 151, and the bottom surface of the positioning platform 150 is the second positioning plane 152. The settings of the first positioning plane 151 and the second positioning plane 152 limit the movement of the drainage drip bottle 100 in two opposite directions, effectively, accurately and quickly positioning the position of the drainage drip bottle 100, which helps to accurately read the intracranial pressure reading.

[0041] When this embodiment is implemented, a positioning space that cooperates with the positioning platform 150 is formed between the lower surface of the positioning block 230 and the upper surface of the clamping assembly 220. The first positioning plane 151 and the second positioning plane 152 are respectively abutted and positioned against the lower surface of the positioning block 230 and the upper surface of the clamping assembly 220, fixing both the upper and lower surfaces of the positioning platform 150. The drainage drip bottle 100 cannot move in the up and down directions. Through the clamping of the drainage drip bottle 100 by the clamping assembly 220, the position of the drainage drip bottle 100 is fixed, effectively, accurately and quickly positioning the position of the drainage drip bottle 100, which helps to accurately read the intracranial pressure reading, as Figure 1 shown.

[0042] Alternatively, when fixedly installing the drainage drip bottle 100 in this embodiment, the lower surface of the positioning block 230 can also be in contact with a plane parallel to the first positioning plane 151 for positioning, and the upper surface of the clamping assembly 220 can also be in contact with a plane parallel to the second positioning plane 152 for positioning. With such an arrangement, the movement of the drainage drip bottle 100 in the up-and-down direction is restricted, and the rotation of the drainage drip bottle 100 backward (with the drainage drip bottle 100 in the front and the scale 400 in the back) is restricted. In addition to the clamping function of the clamping assembly 220, the movement of the drainage drip bottle 100 is restricted from three directions, effectively ensuring the accuracy of the position positioning of the drainage drip bottle 100 and the stability of maintaining the positioned position after positioning.

[0043] Embodiment III

[0044] This embodiment is the third embodiment of the drainage system capable of accurately positioning the drainage drip bottle 100. This embodiment is similar to Embodiment I or Embodiment II. The difference lies in that in this embodiment, the positioning platform 150 is an ear-shaped structure provided on the outer periphery of the bottle body 110. The liquid inlet 120 is connected with a liquid inlet pipe, and the ear-shaped structure is provided with a positioning hole 153 for the liquid inlet pipe to pass through, as Figure 1 shown. The positioning platform 150 of the ear-shaped structure not only plays a positioning role but also plays a role in fixing the liquid inlet pipe, avoiding interference of the liquid inlet pipe on the operation during the installation and movement of the drainage drip pipe. Among them, the upper surface of the ear-shaped structure, that is, the first positioning plane 151 of the positioning platform 150, is flush with the top surface of the drainage drip bottle 100.

[0045] Embodiment IV

[0046] This embodiment is the fourth embodiment of the drainage system capable of accurately positioning the drainage drip bottle 100. This embodiment is similar to Embodiment III. The difference lies in that in this embodiment, the positioning platform 150 is an annular structure surrounding the outer periphery of the bottle body 110. This annular structure can be a complete circular ring structure or a partial arc-shaped annular structure. When the positioning platform 150 is designed as a complete arc-shaped structure, the annular structure can specifically be a cover body detachably connected to the bottle body 110. The diameter of the cover body is larger than the diameter of the bottle body 110, so as to form a positioning step at the connection between the cover body and the bottle body 110. With such an arrangement, the positioning of the drainage drip bottle 100 can be realized by using the bottle cap itself, without separately setting the positioning platform 150, and its manufacturing cost is low and the manufacturing difficulty is low.

[0047] Embodiment V

[0048] This embodiment is the fifth embodiment of the drainage system capable of accurately positioning the drainage drip bottle 100. This embodiment is similar to Embodiments 1 to 4, except that in this embodiment, the side surface of the positioning block 230 abuts against the outer periphery of the liquid inlet 120 and the air inlet 140. Specifically, the positioning block 230 is provided with a third positioning plane perpendicular to the first positioning plane 151. The top of the drainage drip bottle 100 is provided with a liquid inlet 120 and an air inlet 140, and the outer peripheries of the liquid inlet 120 and the air inlet 140 both abut against the third positioning plane, as Figure 1 shown.

[0049] Specifically, in this embodiment, the plane where the axis of the liquid inlet 120 and the axis of the air inlet 140 are located is parallel to the connecting plate 210, and the positioning block 230 is perpendicular to the connecting plate 210. When the drainage drip bottle 100 is positioned and fixed in the positioning space, the outer peripheries of the liquid inlet 120 and the air inlet 140 both abut against the side surface of the positioning block 230. In this embodiment, when the drainage drip bottle 100 is fixed to the fixing device 200, the axes of the liquid inlet 120 and the air inlet 140 are in a plane perpendicular to the positioning block 230. At this time, the positions where the liquid inlet 120 and the air inlet 140 abut against the positioning block 230 form a limiting surface that restricts the rotation of the drainage drip bottle 100. In this way, this embodiment can not only restrict the movement of the drainage drip bottle 100, but also effectively restrict the rotation of the drainage drip bottle 100, and can also make the liquid inlet marking line 160 and the scale marking 170 just face forward, facing the user, which is convenient for the user's operation and the reading of the scale.

[0050] In the specific content of the above specific implementation manner, the technical features can be combined arbitrarily without contradiction. For the sake of brevity of description, not all possible combinations of the above technical features are described. However, as long as the combination of these technical features does not exist in contradiction, it should be considered to be within the scope described in this specification.

[0051] Obviously, the above embodiments of the present invention are only examples for clearly explaining the present invention, and are not limitations on the implementation manners of the present invention. For those of ordinary skill in the art, other different forms of changes or modifications can be made on the basis of the above description. It is not necessary and impossible to enumerate all the implementation manners here. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the claims of the present invention.
