Description

Technical Field

[0001] This invention belongs to the field of ophthalmic medical device technology and relates to an intraocular perfusion fluid infusion alarm device. Background Technology

[0002] During cataract, vitreous, and retinal surgeries, ophthalmologists need to continuously infuse the eye with balanced salt solution (BSS) to stabilize intraocular pressure, support the normal shape of the eyeball, prevent sudden drops in intraocular pressure and eyeball collapse during surgery, and effectively avoid the occurrence of various serious intraoperative complications.

[0003] Currently, doctors typically rely on nurses to manually monitor the infusion during surgery. However, during surgery, medical staff may be preoccupied with other matters and neglect to monitor the infusion fluid, which can easily lead to serious complications during the operation.

[0004] Most existing surgeries rely on manual monitoring. For monitoring medical bottled fluids, this is typically done on the infusion set. For example, Chinese patent application [Patent No.: 202420017772.5] discloses a multifunctional infusion stand, including a base, a support mounted on the base, an electric telescopic rod on the top of the support, a drug protective shell on the output end of the electric telescopic rod, a support column inside the drug protective shell, a weighing sensor at the bottom of the support column, a drug bottle hook on the side of the weighing sensor away from the support column, a first rotating shaft rotatably connected to the drug protective shell, a baffle mounted on the first rotating shaft, and an indicator light on the support near the bottom of the electric telescopic rod.

[0005] The aforementioned structure uses a weighing sensor in conjunction with a medication hook to detect the weight of the infusion bottle. When the detected weight is below a certain value, the weighing sensor sends a signal to an indicator light, which flashes to alert nurses and patients. However, relying solely on gravity detection, which depends on a single weighing sensor, can lead to misjudgments after prolonged use. Furthermore, the detection structure may be inaccurate when detecting small amounts of fluid, affecting the accuracy of the detection. During surgery, precise detection is often required, and different sizes of infusion bottles are needed for different surgical procedures. Therefore, the detection device needs to be adaptable to different infusion bottles and provide accurate detection and alarms. Summary of the Invention

[0006] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing an intraocular perfusion fluid alarm device. The technical problem to be solved by this invention is: how to improve the applicability of the perfusion alarm device while enhancing detection accuracy.

[0007] The objective of this invention can be achieved through the following technical solutions:

[0008] An intraocular irrigation fluid infusion alarm device includes a base and a placement platform. The base has a placement groove, and a pressure sensor is installed at the bottom of the groove. The placement platform is placed in the groove and presses against the pressure sensor. The device is characterized by an adjusting tube rotatably connected to the base, a long, narrow positioning sleeve fitted onto the adjusting tube, and multiple positioning holes vertically formed on the positioning sleeve. An elastic positioning element, partially inserted into the positioning holes, is located inside the adjusting tube. The alarm device also includes a horizontally arranged connecting plate and a vertically arranged plate whose lower end can extend into... The detection rod is inserted into the filling bottle. One end of the connecting plate is fixedly connected to the positioning sleeve, and the other end is slidably connected to the detection sleeve, which is sleeved on the detection rod. The outer side wall of the upper end of the detection rod protrudes circumferentially to form a limiting stop, which can abut against the upper end surface of the detection sleeve. Both the positioning sleeve and the detection sleeve are provided with adjusting racks. The connecting plate is rotatably connected to a synchronous belt that meshes with the two adjusting racks. A float that can move vertically along the detection rod is sleeved on the detection rod. A liquid level sensor is provided on the detection rod to detect the position of the float.

[0009] The filling bottle is placed on the platform. A pressure sensor detects the weight of the liquid inside the bottle. First, the detection rod is pulled upwards, moving it relative to the detection sleeve. The adjusting tube is rotated, causing the positioning sleeve, connecting plate, detection sleeve, and detection rod to move synchronously. The rotation continues until the detection rod and detection sleeve are directly above the bottle opening. Then, the detection rod is moved downwards until its upper limit stop abuts against the detection sleeve. At this point, the float on the detection rod is inside the bottle opening. When the filling bottle is in use, as the liquid level decreases, the float also descends. A level sensor on the detection rod directly detects the float's position, allowing for real-time monitoring of the liquid level in the filling bottle from both gravity and level perspectives, improving the monitoring effect. For filling bottles of different sizes, pressing the elastic positioning element moves the positioning sleeve vertically along the adjusting tube. The positioning sleeve moves the connecting plate synchronously, causing the synchronous belt on the connecting plate to move relative to the adjusting rack on the adjusting tube. When the synchronous belt rotates, it drives the adjusting rack on the detection sleeve to rotate. At this time, the detection sleeve and the positioning sleeve move synchronously in opposite directions, so that no matter how the positioning sleeve and the connecting plate move to make room, the height of the detection rod always remains in the original position. This ensures that the detection rod is always in the same position when detecting the liquid level in the filling bottle, thus ensuring detection accuracy. The synchronous belt engages with the corresponding adjusting rack to ensure that the moving distance of the positioning sleeve and the detection sleeve is equal. However, backlash error can easily occur when the synchronous belt and the adjusting rack move together. Therefore, during adjustment, the elastic positioning element is inserted into the corresponding positioning hole, so that the moving distance of the positioning sleeve is achieved through two adjacent positioning holes, ensuring the accuracy of the positioning sleeve's displacement. Furthermore, when the positioning sleeve and the connecting plate make room for the filling bottle, the detection sleeve and the detection rod can maintain a constant height. This allows for stable and accurate liquid level detection for filling bottles of different sizes, improving the applicability of the filling alarm device and thus improving its detection accuracy.

[0010] Once the liquid level and weight are detected to the preset values, an alarm light or alarm voice can be installed on the base to provide real-time notification of the detected liquid level.

[0011] The filling fluid comes in two types of packaging: glass bottles or soft plastic bags. The soft plastic bags have a certain degree of rigidity.

[0012] In the above-mentioned intraocular irrigation fluid infusion alarm device, the synchronous belt is arranged in the transverse direction. The synchronous belt is a double-toothed synchronous belt. The front and rear sides of the connecting plate have mounting plates. Two rotating gears are hinged on the mounting plates. The synchronous belt is sleeved on the two rotating gears and meshes with the rotating gears.

[0013] The double-sided toothed synchronous belt further enhances the movement accuracy of the synchronous belt during rotation. Furthermore, by hinged a rotating gear on the mounting plate, the synchronous belt is limited by the rotating gear and the adjusting rack during movement, resulting in higher movement accuracy and improving the applicability of the filling alarm device.

[0014] In the above-mentioned intraocular irrigation fluid infusion alarm device, the other end of the connecting plate is provided with a clearance hole through which the upper end of the detection sleeve can pass, and the outer wall of the detection sleeve fits against the wall of the clearance hole.

[0015] The way the wall of the clearance hole fits against the outer wall of the detection sleeve can guide the vertical movement of the detection sleeve, ensuring that the detection sleeve only moves in the vertical direction when it moves. This improves the applicability of the filling alarm device while also increasing the adjustment accuracy.

[0016] In the above-mentioned intraocular irrigation fluid infusion alarm device, the elastic positioning element is a U-shaped spring sheet, which is disposed in the adjustment tube. The adjustment tube is provided with a limiting hole, and the tip of the U-shaped spring sheet can pass through the limiting hole and be inserted into one of the positioning holes.

[0017] U-shaped springs are relatively mature components, so during adjustment, you only need to move the tip of the U-shaped spring out of the positioning hole and then move the positioning slide vertically. This makes it easy to unlock and lock the position of the positioning slide, improving adjustment efficiency.

[0018] In the above-mentioned intraocular irrigation fluid infusion alarm device, the timing belt and the rotating gear are both located between two mounting plates.

[0019] Since the infusion alarm device is located in the operating room, and there are many instruments next to the operating table during surgery, the timing belt and rotating gear are shielded by a mounting plate to prevent medical staff from accidentally touching them, thereby improving the stability of the infusion alarm device.

[0020] In the above-mentioned intraocular infusion fluid infusion alarm device, the outer side wall of the lower end of the detection rod protrudes axially to form a stop edge, and the float can abut against the stop edge.

[0021] The design of the abutment edge allows the float to be restrained on the detection rod by abutting the edge when not in use, improving ease of use.

[0022] In the above-mentioned intraocular irrigation fluid infusion alarm device, the adjusting rack on the adjusting tube and the positioning hole are arranged radially opposite to each other along the positioning sleeve, and the positioning hole is arranged outward.

[0023] The design of this structure ensures that the presence of positioning holes does not affect the setting of the adjusting rack, making the spatial arrangement of each component more reasonable.

[0024] In the above-mentioned intraocular irrigation fluid infusion alarm device, one end of the connecting plate has two connecting arms arranged in parallel, the positioning sleeve is located between the two connecting arms and fixedly connected to the connecting arms, the inner sidewall of the connecting arm has an arc-shaped surface that fits with the positioning sleeve, and the positioning hole is located outside the connecting arm.

[0025] The connecting arm allows for a stable connection with the positioning sleeve and also allows for clearance of the positioning hole, making it easier for the positioning sleeve to move the end of the elastic positioning element out of the positioning hole when unlocking, thus improving the convenience of operation and the stability of the filling alarm device.

[0026] In the above-mentioned intraocular irrigation fluid infusion alarm device, an annular mounting groove is provided at the corner of the base, and the lower end of the adjusting tube is embedded in the mounting groove.

[0027] The mounting groove design allows the lower end of the regulating tube to be simply inserted into the mounting groove for a tight fit, facilitating the installation of the regulating tube. Furthermore, the groove wall can guide and limit the rotation of the regulating tube, improving the stability of the rotation.

[0028] In the above-mentioned intraocular infusion alarm device, the sidewall of the placement groove has multiple ring-shaped positioning bosses that can be used to place the infusion bottle, and the diameter of the multiple positioning bosses gradually decreases from top to bottom.

[0029] The positioning boss facilitates the placement of filling bottles of different diameters, allowing it to accommodate filling bags or bottles of different sizes and preventing them from tipping over, thus improving the practicality of the alarm device.

[0030] Compared with existing technologies, this intraocular perfusion fluid alarm device has the following advantages:

[0031] 1. For filling bottles of different sizes, pressing the elastic positioning element causes the positioning sleeve to move vertically along the adjusting tube. The positioning sleeve drives the connecting plate to move synchronously. At this time, the synchronous belt on the connecting plate moves relative to the adjusting rack on the adjusting tube, causing the synchronous belt to rotate. This rotates the adjusting rack on the detection sleeve, causing the detection sleeve and the positioning sleeve to move synchronously in opposite directions. This ensures that no matter how the positioning sleeve and the connecting plate move, the height of the detection rod remains in its original position, guaranteeing that the detection rod is always in the same position when detecting the liquid level in the filling bottle, thus ensuring detection accuracy. The synchronous belt engages with the corresponding adjusting rack to ensure accuracy. The positioning sleeve and the detection sleeve move the same distance. However, backlash error can easily occur when the synchronous belt and the adjusting rack move together. Therefore, during adjustment, the elastic positioning element is inserted into the corresponding positioning hole, so that the movement distance of the positioning sleeve is achieved through two adjacent positioning holes. This ensures the accuracy of the positioning sleeve's movement displacement. Furthermore, when the positioning sleeve and the connecting plate make way for the filling bottle, the detection sleeve and the detection rod can maintain a constant height. This allows for stable and accurate liquid level detection for filling bottles of different sizes, improving the applicability of the filling alarm device and thus enhancing its detection accuracy.

[0032] 2. The connecting arm enables a stable connection with the positioning sleeve and also allows for clearance of the positioning hole, making it easier for the positioning sleeve to move the end of the elastic positioning element out of the positioning hole when unlocking, thus improving the convenience of operation and the stability of the filling alarm device.

[0039] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings to further illustrate the technical solutions of the present invention. However, the present invention is not limited to these embodiments.

[0040] like Figure 1-3 As shown, the intraocular infusion fluid infusion alarm device includes a base 1 and a placement platform 2. A placement groove 11 is provided on the base 1, and a pressure sensor 12 is provided at the bottom of the placement groove 11. The placement platform 2 is placed in the placement groove 11 and presses against the pressure sensor 12.

[0041] Specifically, such as Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, an adjusting tube 3 is rotatably connected to the base 1. A long, narrow positioning sleeve 4 is fitted onto the adjusting tube 3. The positioning sleeve 4 has multiple positioning holes 41 vertically. An elastic positioning element 5 is provided inside the adjusting tube 3, which can partially pass through the positioning holes 41. This alarm device also includes a connecting plate 6 arranged horizontally and a detection rod 7 arranged vertically, the lower end of which can extend into the filling liquid bottle. One end of the connecting plate 6 is fixedly connected to the positioning sleeve 4, and the other end is slidably connected to a detection sleeve 71. The detection sleeve 71 is fitted onto the detection rod 7. The outer side wall at the upper end protrudes circumferentially to form a limiting stop 74, which can abut against the upper end surface of the detection sleeve 71. Both the adjusting tube 3 and the detection sleeve 71 are provided with adjusting racks 8. The positioning sleeve 4 is provided with a clearance notch 42 that allows the adjusting rack 8 on the adjusting tube 3 to be partially exposed. The connecting plate 6 is rotatably connected with a synchronous belt 9 that meshes with the two adjusting racks 8. A float 72 that can move vertically along the detection rod 7 is sleeved on the detection rod 7. A liquid level sensor 73 is provided on the detection rod 7 to detect the position of the float 72.

[0042] Place the filling bottle on the placement platform 2. The weight of the liquid inside the filling bottle is detected by the pressure sensor 12. First, pull the detection rod 7 upwards. The detection rod 7 moves upwards relative to the detection sleeve 71. Rotate the adjusting tube 3. The rotation of the adjusting tube 3 causes the positioning sliding sleeve 4, connecting plate 6, detection sleeve 71, and detection rod 7 to move synchronously. Rotate until the detection rod 7 and detection sleeve 71 are directly above the mouth of the filling bottle. Then, move the detection rod 7 downwards until the upper limit stop 74 of the detection rod 7 abuts against the detection sleeve 71. At this time, the float 72 of the detection rod 7 is located inside the mouth of the filling bottle. In use, as the liquid level in the bottle decreases, the float 72 also descends. A level sensor 73 on the detection rod 7 directly detects the position of the float 72, enabling real-time monitoring of the liquid level in the filling bottle from both gravity and liquid level perspectives, thus improving the monitoring effect. For filling bottles of different sizes, pressing the elastic positioning element 5 causes the positioning sliding sleeve 4 to move vertically along the adjusting tube 3. The positioning sliding sleeve 4 drives the connecting plate 6 to move synchronously. At this time, the synchronous belt 9 on the connecting plate 6 moves relative to the adjusting rack 8 on the adjusting tube 3. When the synchronous belt 9 rotates, it drives the adjusting rack 8 on the detection sleeve 71 to rotate. At this time, the detection sleeve 71 and the positioning sleeve 4 move synchronously in opposite directions, so that no matter how the positioning sleeve 4 and the connecting plate 6 move to make room, the height of the detection rod 7 always remains in the original position. This ensures that the detection rod 7 is always in the same position when the liquid level in the filling bottle is detected, thus ensuring detection accuracy. The synchronous belt 9 and the corresponding adjusting rack 8 are engaged to ensure that the moving distance of the positioning sleeve 4 and the detection sleeve 71 are equal. However, backlash error can easily occur when the synchronous belt 9 and the adjusting rack 8 move together. Therefore, during adjustment, the elastic positioning element 5 is inserted into the corresponding positioning hole 41 to position the positioning sleeve 4. The movement distance of the positioning sleeve 4 is achieved through two adjacent positioning holes 41, ensuring the accuracy of the movement displacement of the positioning sleeve 4. Furthermore, when the positioning sleeve 4 and the connecting plate 6 make way for the filling bottle, the detection sleeve 71 and the detection rod 7 can maintain a constant height. This enables stable and accurate liquid level detection for filling bottles of different sizes, improves the applicability of the filling alarm device, and thus improves the detection accuracy of the filling alarm device.

[0043] Once the liquid level and weight are detected to the preset values, an alarm light or alarm voice can be installed on the base 1 to provide real-time notification of the liquid level detection.

[0044] like Figure 3-5 As shown, the synchronous belt 9 is arranged in the transverse direction. The synchronous belt 9 is a double-toothed synchronous belt. The front and rear sides of the connecting plate 6 have mounting plates 61. Two rotating gears 62 are hinged on the mounting plates 61. The synchronous belt 9 is sleeved on the two rotating gears 62 and the synchronous belt 9 meshes with the rotating gears 62.

[0045] like Figure 3 and Figure 4 As shown, the other end of the connecting plate 6 is provided with a clearance hole 63 through which the upper end of the detection sleeve 71 can pass. The outer wall of the detection sleeve 71 fits against the wall of the clearance hole 63. The outer wall of the lower end of the detection rod 7 protrudes axially to form an abutment flange 75, and the float 72 can abut against the abutment flange 75.

[0046] like Figure 3 and Figure 4 As shown, the elastic positioning element 5 is a U-shaped spring sheet, which is installed inside the adjusting tube 3. The adjusting tube 3 has a limiting hole 31. The tip 51 of the U-shaped spring sheet can pass through the limiting hole 31 and be inserted into one of the positioning holes 41. The synchronous belt 9 and the rotating gear 62 are both located between the two mounting plates 61.

[0047] like Figure 4 and Figure 5 As shown, the adjusting rack 8 on the positioning sleeve 4 and the positioning hole 41 are arranged radially opposite to each other along the positioning sleeve 4, with the positioning hole 41 facing outward. One end of the connecting plate 6 has two parallel connecting arms 64. The positioning sleeve 4 is located between the two connecting arms 64 and is fixedly connected to the connecting arms 64. Specifically, the positioning sleeve 4 is fixedly connected to the connecting arm 64 radially by fastener 10. The inner sidewall of the connecting arm 64 has an arc-shaped surface 64a that fits with the positioning sleeve 4, and the positioning hole 41 is located outside the connecting arm 64.

[0048] like Figure 1 and Figure 3 As shown, an annular mounting groove 13 is provided at the corner of the base 1, and the lower end of the adjusting tube 3 is embedded in the mounting groove 13.

[0049] like Figure 1-3 As shown, the sidewall of the placement groove 2 has multiple ring-shaped positioning bosses 21 for placing filling bottles, and the diameter of the multiple positioning bosses 21 gradually decreases from top to bottom.

[0050] The specific embodiments described herein are merely illustrative of the spirit of the invention. Those skilled in the art to which this invention pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of the invention or exceeding the scope defined by the appended claims.
