Description

Technical Field

[0001] The present application relates to the field of drainage catheter auxiliary instruments, and in particular to a pendulum-type anti-slip surgical drainage catheter fixer. Background Art

[0002] A surgical drain, also known as a drainage catheter, is a medical catheter placed into the body cavity, tissue space, organ, or wound surface through surgery or puncture. It is used to drain fluid, gas, or necrotic tissue, prevent postoperative infection, promote wound healing, and monitor the condition. It is a common surgical treatment measure.

[0003] Unplanned extubation (UEX) refers to the accidental slippage of the intubation tube. The patient removes the tube without the consent of the medical staff and without meeting the extubation indications. This includes accidental extubation caused by improper operation of the medical staff. Among them, excessive traction caused by the patient's daily activities is also an important cause of unplanned extubation.

[0004] Currently, surgical drainage tubes are fixed clinically based on suture fixation, using surgical sutures to fix the drainage tube to the skin around the drainage tube opening, supplemented by various new medical dressings such as medical tape and hydrocolloid dressings for secondary fixation.

[0005] However, relying solely on this fixing method to fix the drainage tube is prone to unplanned extubation in actual applications. Specifically, when the patient is in bed, the drainage bag connected to the drainage tube is generally fixed on one side of the bed. In this way, when the patient turns over, gets out of bed, or moves around in bed, unplanned extubation may easily occur due to tube traction. Therefore, there is room for improvement. Summary of the Invention

[0006] In order to solve at least one of the technical problems mentioned in the background technology, the purpose of the present application is to provide a pendulum-type anti-slip surgical drainage catheter holder.

[0007] To achieve the above objectives, this application provides the following technical solutions.

[0009] A base body, wherein the base body includes a first surface and a second surface on opposite sides along a first direction;

[0010] A carrier plate is disposed on the first surface of the base, the carrier plate being provided with one or more embedding grooves for embedding the drainage catheter, the embedding grooves being provided with clamping members for clamping the drainage catheter; the carrier plate being capable of rotating in two directions relative to the base around the first axis from an initial position to form an arc-shaped rotation trajectory, wherein the maximum rotation angle of the carrier plate relative to the base in both directions does not exceed 90°, and in the initial position, the embedding grooves extend in a direction perpendicular to a line connecting the two ends of the arc-shaped trajectory;

[0011] The attachment is provided on the second surface of the base and is used for attaching the base to a human body.

[0012] As an optional embodiment of the present application, the base and the carrier are located on opposite side surfaces, one of which is provided with a limiting protrusion and the other is provided with an arc-shaped track groove, the center of the arc-shaped track groove coincides with the first axis; the limiting protrusion is at least partially inserted into the arc-shaped track groove and can move in the arc-shaped track groove; the central angle formed by the two ends of the arc-shaped track groove to the center of the circle does not exceed 180°, and in the initial position, the extension direction of the embedded groove is perpendicular to the line connecting the two ends of the arc-shaped track groove.

[0013] As an optional embodiment of the present application, the attachment includes an adhesive attached to the second surface of the base, and the surface of the adhesive away from the base is sticky; and / or the attachment includes a strap, the two ends of the strap are adhered to each other by a Velcro structure, and the base is arranged on the strap.

[0014] As an optional embodiment of the present application, the fixer also includes a reminder mechanism, which includes a pressure sensor and a warning member; the pressure sensor is used to detect the pressure value of the substrate and / or the carrier from a first direction, and the warning member is configured to send a warning signal when the pressure value detected by the pressure sensor is greater than or equal to a set value.

[0015] As an optional implementation of the present application, the warning signal includes at least one of a vibration signal that causes the fixer to vibrate, a light signal, and a sound signal.

[0016] As an optional embodiment of the present application, the clamping member includes a first protrusion, the embedding groove is located on two side groove walls on opposite sides, at least one of which is provided with the first protrusion; and / or the clamping member includes a flexible clamping block, the flexible clamping block is provided with a clamping groove for embedding the drainage catheter, and the clamping block is used to embed in the embedding groove; in the assembled state, the drainage catheter is embedded in the clamping groove, and the clamping block is embedded in the embedding groove with an interference fit so that the drainage catheter is clamped in the clamping groove.

[0017] As an optional embodiment of the present application, the holder further comprises a cover, which is detachably covered on the top of the carrier plate; wherein a relief opening for evacuating the drainage duct is provided on the side wall of the cover.

[0018] As an optional embodiment of the present application, a second protrusion for pressing the drainage catheter is provided at a corresponding groove position on the inner wall of the cover body facing the carrier; and / or an identification area for identifying drainage catheter information is provided at a corresponding groove position on the top wall of the cover body.

[0019] As an optional embodiment of the present application, a positioning portion is formed on the peripheral wall of the cover body, and a positioning groove is provided on the peripheral wall of the carrier plate for the positioning portion to be inserted along the first direction. When the positioning portion is inserted into the positioning groove, the avoidance opening is aligned with the embedding groove.

[0020] As an optional embodiment of the present application, an elastic arm is provided on the positioning portion, a locking step is formed on the inner side of the elastic arm, and a snap-in groove for the locking step to be inserted is provided on the groove wall of the positioning groove corresponding to the position of the locking step.

[0021] Compared with the prior art, this application has the following beneficial effects:

[0022] The present application provides a carrier that can rotate relative to the base, and the clamping of the clamping piece is coordinated with the embedding groove on the carrier. In this way, when fixing the drainage catheter, the drainage catheter can be clamped and fixed in the embedding groove by the clamping piece, and the clamping position of the clamping piece is recorded as the clamping point; the entire fixer is fixed to the patient's body or clothing through the attachment, so that the drainage catheter is equivalent to being divided into two sections with the clamping point of the carrier as the boundary, the first section is the pipe section between the position where the drainage catheter is led out of the human body and the clamping point of the carrier, and the second section is the pipe section between the clamping point of the carrier to the drainage bag connected to the drainage catheter.

[0023] Generally speaking, the first section of the aforementioned drainage catheter is generally not susceptible to excessive traction, and the second section of the drainage catheter is susceptible to traction. Since the second section of the drainage catheter is clamped at the clamping point, even if the second section of the drainage catheter is pulled, the resulting traction force will only act on the clamping point and will basically not act on the first section of the drainage catheter. This effectively reduces the probability of unplanned extubation of the drainage catheter due to traction.

[0024] In addition, in the present application, the carrier plate is capable of rotating or swinging to both sides based on the initial position. In this way, when the patient is lying in bed and the second section of the drainage catheter is pulled due to turning over, the carrier plate can adapt to the pulling force and rotate toward the pulled side, thereby playing a buffering role and reducing the pulling force generated on the clamping point.

[0025] In addition, with this rotating carrier plate design, even if the drainage catheter shakes left and right under the action of gravity, the carrier plate can rotate freely along with it, so that the drainage catheter will not slip off at the clamping point.

[0026] Finally, in this application, the maximum rotation angle of the carrier plate is limited, that is, the left and right rotations do not exceed 90°; this setting prevents the occurrence of unplanned extubation due to excessive rotation of the carrier plate. Specifically: if the rotation angle of the carrier plate is too large, the first section of the drainage catheter will be greatly pulled due to the rotation of the carrier plate, which will cause the first section of the drainage catheter to generate a large traction force, thereby causing the problem of unplanned extubation.

[0027] It should be understood that the content described in this section is not intended to identify the key or important features of the embodiments of the present application, nor is it intended to limit the scope of the present application. Other features of the present application will become easily understood through the following description. BRIEF DESCRIPTION OF THE DRAWINGS

[0050] In order to make the purpose, features, and advantages of this application more obvious and easy to understand, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without making creative efforts shall fall within the scope of protection of this application.

[0051] Reference Figure 1-12 As shown, this embodiment provides a pendulum-type anti-slip surgical drainage catheter fixer, which is mainly used to fix the drainage catheter (referred to as the drainage tube) and reduce the probability of unplanned extubation. To facilitate understanding, this embodiment first briefly introduces the drainage catheter. Generally speaking, one end of the drainage catheter is connected to a drainage bag, and the other end is connected to the human body for drainage. After the drainage catheter is led out of the human body, surgical sutures are used to fix the drainage catheter to the skin around the drainage tube opening, supplemented by the use of various new medical dressings such as medical tape and hydrocolloid dressings for secondary fixation.

[0052] like Figure 1 As shown, the fixture provided in this embodiment mainly includes a base 1, a carrier plate 2 and an attachment 4. The following is a detailed description of each component:

[0053] The base 1 can be made of a hard material, such as plastic, or a flexible material, such as rubber. Its shape is generally circular, but other shapes are possible depending on actual needs. Furthermore, along a first direction D1, the base 1 includes a first surface and a second surface on opposite sides. The first direction D1 herein can also be understood as the axial direction of the base 1. For example, from the perspective shown in the figure, the top surface of the base 1 constitutes the first surface, and the bottom surface of the base 1 constitutes the second surface.

[0054] In some embodiments, the carrier plate 2 is a disc structure, and the carrier plate 2 is arranged on the first surface of the base 1, that is, the carrier plate 2 is arranged on the top of the base 1, and the carrier plate 2 can rotate around the first axis relative to the base 1. Specifically, a rotating shaft 11 is provided on the carrier plate 2, and the carrier plate 2 is rotatably connected to the rotating shaft 11 through a bearing, wherein the axis of the rotating shaft 11 constitutes the first axis.

[0055] The rotation angle of the carrier plate 2 around the first axis is limited to a certain range. Specifically, the carrier plate 2 rotates from the initial position to both sides to form an arc-shaped rotation trajectory. Figure 10 As shown, this description can also be understood as follows: one of the diameter lines of the carrier 2 is used as the reference line L1. The initial position of the carrier 2 can be understood as the initial position of the reference line L1. The reference line L1 can be rotated clockwise around the first axis from the initial position to the first position, or can be rotated counterclockwise around the first axis from the initial position to the second position. The rotation path of the reference line L1 between the first position and the second position constitutes the aforementioned arc-shaped rotation trajectory, which can also be understood as Figure 10 Middle arc-shaped track groove 22.

[0056] In addition, the maximum rotation angle of the carrier 2 relative to the base 1 from the initial position to the sides does not exceed 90 degrees, that is, the maximum rotation angle of the reference line L1 from the initial position to the sides does not exceed 90 degrees; taking the maximum rotation angle of 90 degrees as an example, it can be understood as follows: with the clock position as a reference, in the initial position, if Figure 10 As shown, the reference line L1 points to the 6 o'clock position; the reference line L1 rotates 90° clockwise from the initial position to the first position, as shown Figure 11 As shown, the reference line L1 now points to the 9 o'clock position; the reference line L1 rotates 90° counterclockwise from the initial position to the second position, as shown Figure 12 As shown, the reference line L1 now points to the 3 o'clock position.

[0057] like Figure 4As shown, the carrier plate 2 is provided with one or more embedding grooves 21 for embedding the drainage catheter. The multiple embedding grooves 21 are arranged side by side, and the embedding grooves 21 extend substantially in a horizontal straight line, with the tops of the embedding grooves 21 open. The specific number of the embedding grooves 21 can be determined according to the actual number of drainage catheters to be fixed. For example, this embodiment shows the use of three embedding grooves 21, one of which is located on the diameter line of the carrier plate 2, and the other two embedding grooves 21 are respectively arranged side by side on both sides of the embedding groove 21 on the diameter line.

[0058] In addition, in the initial position, Figure 10 As shown, the extending direction of the embedding groove 21 is perpendicular to the line L2 connecting the two ends of the arc-shaped trajectory. The extending direction of the embedding groove 21 can also be understood as the length direction of the embedding groove 21. Taking the above description as an example, the line L2 connecting the two ends of the arc-shaped trajectory can also be understood as the line L2 between the first position and the second position. Taking the maximum rotation angle of 90° as an example, the line L2 between the first position and the second position is equivalent to one of the diameter lines of the carrier 2. When the carrier 2 is in the initial position, the reference line L1 is perpendicular to this diameter line.

[0059] Taking the embedding groove 21 on the diameter line as an example, the embedding groove 21 rotates clockwise from the initial position to a maximum angle of 90 degrees, and the maximum angle of counterclockwise rotation is also 90 degrees. A clamping member 3 for clamping the drainage catheter is provided in the embedding groove 21.

[0060] When in use, a portion of the drainage catheter is inserted into the embedded groove 21 along the direction of the embedded groove 21, and is clamped and fixed by the clamping member 3, and the entire fixator is attached to the human skin (such as the abdomen) or clothing through the attachment member 4, so that the fixator is fixed.

[0061] Since part of the drainage catheter extends along the length direction of the embedding groove 21 and is clamped in the embedding groove 21 by the clamping member 3, the position where the clamping member 3 presses the drainage catheter is equivalent to a clamping point.

[0062] The entire drainage catheter is divided into two sections with the clamping point of the carrier plate 2 as the boundary. The first section is the section of the tube from the position where the drainage catheter is led out of the human body to the clamping point of the carrier plate 2, which is recorded as the first section of the drainage catheter; the second section is the section of the tube from the clamping point of the carrier plate 2 to the drainage bag connected to the drainage catheter, which is recorded as the second section of the drainage catheter.

[0063] Generally speaking, the first section of the aforementioned drainage catheter is generally not susceptible to excessive traction, and the second section of the drainage catheter is susceptible to traction. Since the second section of the drainage catheter is clamped at the clamping point, even if the second section of the drainage catheter is pulled, the resulting traction force will only act on the clamping point and will basically not act on the first section of the drainage catheter. This effectively reduces the probability of unplanned extubation of the drainage catheter due to traction.

[0064] In addition, in this embodiment, the carrier plate 2 is capable of rotating or swinging to both sides based on the initial position. In this way, when the patient is lying in bed and the second section of the drainage catheter is pulled due to turning over, the carrier plate 2 can adapt to the pulling force and rotate toward the pulled side, thereby playing a buffering role and reducing the pulling force generated on the clamping point.

[0065] In addition, with such a rotating carrier plate 2 design, even if the drainage catheter shakes left and right under the action of gravity, the carrier plate 2 can rotate freely along with it, so that the drainage catheter will not slip off at the clamping point.

[0066] In addition, it can be understood that when clamping the drainage catheter, it is necessary to ensure that the first section of the drainage catheter has sufficient margin to accommodate the carrier plate 2 when it is rotated to the maximum rotation of 90°, that is, when the carrier plate 2 is rotated clockwise or counterclockwise to the maximum angle position, the first section of the drainage catheter will not be tensioned.

[0067] The attachment 4 in this embodiment is mainly used to attach the base 1 or the entire fixture to a human body, where the human body can be the skin of the human body or clothing worn on the human body.

[0068] In order to limit the maximum rotation angle of the carrier 2 relative to the base 1, in some embodiments, Figure 5 and Figure 10 As shown, the base 1 and the carrier plate 2 are located on opposite sides, one of which is provided with a limiting protrusion 12, and the other is provided with an arcuate track groove 22, the center of the arcuate track groove 22 coincides with the first axis, that is, the arcuate track groove 22 and the carrier plate 2 are in a concentric state.

[0069] Specifically, what is shown in this embodiment is that Figure 5 As shown, the arc-shaped track groove 22 is provided on the bottom surface of the carrier plate 2. Figure 1 As shown, the limiting protrusion 12 is provided on the top surface of the base 1; and the limiting protrusion 12 is at least partially inserted into the arc track groove 22 and can move in the arc track groove 22; Figure 10 As shown, the central angle formed by the two ends of the arc-shaped track groove 22 to the center of the circle does not exceed 180°. Preferably, the central angle is 180°, that is, the line L2 connecting the two ends of the arc-shaped track groove 22 passes through the center of the carrier 2; and in the initial position, as shown Figure 10 As shown, the extending direction of the embedding groove 21 is perpendicular to the connecting line L2 of the two ends of the arc-shaped track groove 22 . It can also be understood that the extending direction of the embedding groove 21 is parallel to the aforementioned reference line L1 .

[0070] Thus, the maximum clockwise rotation angle of the carrier plate 2 from the initial position is limited to 90°, and the maximum counterclockwise rotation angle is also 90°; in short, the maximum left and right rotation angles of the carrier plate 2 from the initial position are both 90°.

[0071] The significance of such a setting is to prevent the occurrence of unplanned extubation due to excessive rotation of the carrier plate 2. Specifically, if the carrier plate 2 rotates too much, the first section of the drainage catheter will be greatly pulled due to the large rotation angle of the carrier plate 2. This will cause the first section of the drainage catheter to generate a large traction force, thereby causing the problem of unplanned extubation.

[0072] In some embodiments, the attachment 4 includes an adhesive attached to the second surface of the substrate 1, and the surface of the adhesive away from the substrate 1 is sticky; for example, Figure 2 As shown, the adhesive attachment can be a medical patch 41, which has a spunlace non-woven fabric coated with medical acrylic adhesive as its base material; that is, one side of the patch 41 is fixed to the bottom surface of the base 1 by gluing, and the other side is coated with glue and covered with release paper; when in use, the release paper is torn off and the patch 41 is adhered to the skin of the human abdomen so that the entire fixator can be fixed to the human abdomen.

[0073] Of course, in combination with some other optional embodiments, Figure 3 As shown, the attachment 4 can also be a strap 42, preferably an elastic strap 42; the two ends of the strap 42 are bonded together by a Velcro structure, which mainly includes a first portion with a fleece surface and a second portion with a barbed surface capable of adhering to the fleece surface, the first portion and the second portion being respectively provided at the two ends of the strap 42; and the base 1 is fixed to the strap 42. When used in this manner, the strap 42 can be tied and worn on the abdomen of the human body, thereby also achieving the purpose of fixing the entire fixator on the abdomen of the human body.

[0074] Of course, the attachment 4 can also be a combination of the aforementioned patch 41 and the strap 42, such as Figure 3 In the state shown, the base body 1 is adhered to the strap 42 by the patch 41. After use, the entire fastener can be removed from the strap 42.

[0075] In some embodiments, the clamping member 3 includes one or more members. Specifically, the clamping member 3 includes a first protrusion 31 . The first protrusion 31 can be made of plastic or rubber.

[0076] like Figure 4 As shown, the embedding groove 21 is located on two side groove walls on opposite sides, at least one of which is provided with the first protrusion 31. Preferably, the groove walls on both sides of the embedding groove 21 are provided with oppositely arranged first protrusions 31, and the drainage catheter is clamped in the embedding groove 21 by the first protrusions 31 on both sides.

[0077] In actual applications, some drainage catheters may not be clamped by the first protrusion 31 due to their own small diameter; therefore, in some embodiments, such as Figure 4 As shown, the clamping member 3 further includes a flexible clamping block 32, for example, a clamping block 32 made of rubber material; the flexible clamping block 32 is provided with a clamping groove 321 for the drainage catheter to be embedded, so that the entire clamping block 32 is roughly U-shaped.

[0078] The clamping block 32 is used to be embedded in the embedding groove 21; in the assembled state, the drainage catheter is embedded in the clamping groove 321, and the clamping block 32 is embedded in the embedding groove 21 with an interference fit so that the drainage catheter is clamped in the clamping groove 321, that is, when the clamping block 32 is embedded in the embedding groove 21, it will squeeze the two sides of the clamping block 32 to gather towards the middle, so that the side walls on both sides of the clamping block 32 tightly embrace the drainage catheter embedded therein; in this way, the drainage catheter is clamped.

[0079] There may be one or more card blocks 32 , and as spare parts, the card blocks 32 may be designed in a variety of different models and sizes to correspond to drainage catheters of different sizes and models.

[0080] In order to prevent the portion of the drainage catheter embedded in the embedding groove 21 from being accidentally squeezed, in some embodiments, such as Figure 1 As shown, the fixture further includes a cover 5, which is detachably covered on the top of the carrier plate 2, for example, by being clamped or screwed.

[0081] Furthermore, to allow the drainage tube to pass smoothly through the cover 5, in some embodiments, a relief opening 51 for the drainage tube is provided on the sidewall of the cover 5. The presence of the cover 5 can block the portion of the drainage tube embedded in the groove 21, preventing this portion of the tube from being accidentally squeezed.

[0082] In addition, in order to further improve the fixation effect of the drainage catheter, in some embodiments, such as Figure 8 As shown, a second protrusion 52 for pressing the drainage tube is provided on the inner wall of the cover body 5 facing the carrier side at a position corresponding to the embedding groove 21. In this way, after the cover body 5 is closed, the second protrusion 52 will generate a pressing force on the drainage tube toward the carrier 2. In this way, combined with the clamping of the first protrusion 31, the two are clamped together to improve the fixing effect.

[0083] In some embodiments, such as Figure 2As shown, an identification area 53 for identifying drainage catheter information is provided on the top wall of the cover body 5 at a position corresponding to the embedding groove 21. One identification area 53 corresponds to one embedding groove 21, and the identification area 53 is located directly above the corresponding embedding groove 21. The identification area 53 here can be a replaceable identification paper adhered to the cover body 5, and the identification information is recorded on the identification paper. The identification information includes the name of the drainage catheter, the length of the drainage catheter, the time of catheterization, etc.

[0084] In this embodiment, the cover 5 is clamped on the top of the carrier plate 2 as an example for specific description:

[0085] like Figure 9 As shown, the peripheral wall of the cover body 5 is formed with a positioning portion 54, and the specific formation of the positioning portion 54 can be that part of the peripheral wall of the cover body 5 is formed by protruding inward; Figure 4 As shown, a positioning groove 23 is provided on the peripheral wall of the carrier 2 for the positioning portion 54 to be inserted along the first direction D1. When the positioning portion 54 is inserted into the positioning groove 23, the avoidance opening 51 is aligned with the embedding groove 21, so as to play a positioning role in the installation of the cover body 5, ensuring that the avoidance opening 51 and the embedding groove 21 can be aligned and the two are not misaligned.

[0086] like Figure 9 As shown, the positioning portion 54 is provided with an elastic arm 541, and a locking step 542 is formed on the inner side surface of the elastic arm 541 (the side surface of the elastic arm 541 facing the carrier 2); Figure 4 As shown, the slot wall of the positioning slot 23 is provided with a snap-in slot 231 for the snap-in step 542 to snap into at the position corresponding to the snap-in step 542; when the positioning portion 54 of the cover 5 is aligned with the positioning slot 23 and continuously inserted downward, as shown in FIG. Figure 6 and Figure 7 As shown, when the latch moves to the latch groove 231 , the latch step 542 is latched into the latch groove 231 under the elastic force of the elastic arm 541 , thereby achieving latching and fixing, and the cover 5 is thus fastened to the carrier 2 .

[0087] In some embodiments, in order to drive the locking step 542 out of the locking slot 231 to achieve unlocking, a paddle 543 is provided on the outer wall of the elastic arm 541. When unlocking is required, the paddle 543 can be pushed outward with a finger to drive the elastic arm 541 to move outward, thereby causing the locking step 542 to be disengaged from the locking slot 231 to achieve unlocking.

[0088] Furthermore, when a patient is wearing the restraint and lying in bed, if the patient turns over and assumes a prone sleeping position, the patient may easily press on the drainage tube, thereby squeezing the drainage tube and affecting the drainage effect. Based on this, in some embodiments, in order to remind the patient to change his sleeping position, the restraint is further improved:

[0089] The holder also includes a reminder mechanism, which includes a pressure sensor 6, a controller (not shown in the figure), and a warning member (not shown in the figure); the pressure sensor 6 is used to detect the pressure value of the substrate 1 and / or the carrier plate 2 from the first direction D1, and the warning member is configured so that when the pressure value detected by the pressure sensor 6 is greater than or equal to the set value, the controller controls the warning member to send a warning signal.

[0090] Specifically, the pressure sensor 6 can be disposed on the top surface of the cover 5 or between the attachment 4 and the base 1 ; the pressure sensor 6 can be disposed within the base 1 ; furthermore, a battery for powering the pressure sensor 6 and the controller can be disposed within the base 1 , or the pressure sensor 6 and the controller can be powered directly by a mains connection, without specific limitations. The controller can be disposed within the base 1 .

[0091] In this way, when the patient is in a prone sleeping position, the entire fixator will be pressed under the body, thereby generating pressure on the fixator. The pressure is detected by the pressure sensor 6 to obtain a pressure value. When the pressure value is greater than or equal to the set value, the controller will control the warning element to send a warning signal to alert the patient or medical staff.

[0092] The warning signal includes at least one of a vibration signal that causes the fixator to vibrate, a light signal, and an audio signal. Specifically, the vibration signal can be generated by installing a vibration motor (not shown) within the base 1. The motor's vibration drives the fixator to vibrate, generating a vibration signal to alert the patient. Alternatively, a buzzer can be installed on the base 1 to generate an audio signal, or a signal light can be installed on the base 1 to generate an audio signal. The specific warning signal can be selected based on actual needs, with a vibration signal being preferred.
