Description

Technical Field

[0001] This application relates to the field of drainage catheter auxiliary instruments, and particularly to a pendulum-type anti-slip surgical drainage catheter fixator. Background Art

[0002] A surgical drain, also known as a drainage catheter, is a medical catheter inserted into the body cavity, tissue space, internal organ, or wound surface of the human body through surgery or puncture, used to drain fluids, gases, or necrotic tissues, prevent postoperative infections, promote wound healing, and observe the condition of the disease, which is a common surgical treatment measure.

[0003] Unplanned Extubation (UEX) refers to the accidental slippage of the intubation tube, and the patient removes the tube without the consent of medical staff and without meeting the extubation criteria, including accidental removal caused by improper operation of medical staff; among them, excessive traction caused by the patient's daily activities is also an important reason for unplanned extubation.

[0004] Currently, in clinical practice, the surgical drainage tube is fixed based on the suture fixation method. The drainage tube is fixed to the skin around the drainage orifice using surgical sutures, and various new medical dressings such as medical tapes and hydrocolloid dressings are used for secondary fixation.

[0005] However, relying solely on this fixation method to fix the drainage tube, in actual application, unplanned extubation is likely to occur. Specifically, when the patient is in bed, the drainage bag connected to the drainage tube is generally fixed and hung on one side of the hospital bed. In this way, when the patient turns over, gets out of bed, or moves in bed, it is easy for unplanned extubation events to occur due to the pulling of the pipeline, so there is still room for improvement. Summary of the Invention

[0006] In order to solve at least one technical problem mentioned in the background art, the purpose of this application is to provide a pendulum-type anti-slip surgical drainage catheter fixator.

[0007] To achieve the above purpose, the present application provides the following technical solutions.

[0008] A pendulum-type anti-slip surgical drainage catheter fixator, comprising: A base body, along a first direction, the base body includes a first surface and a second surface on opposite sides; A carrier plate is provided on the first surface of the base body. One or more grooves for embedding a drainage catheter are provided on the carrier plate, and a clamping member for clamping the drainage catheter is provided in the groove; the carrier plate can rotate relative to the base body around a first axis from an initial position to both sides to form an arc-shaped rotation trajectory. Among them, the maximum rotation angle of the carrier plate relative to the base body rotating to both sides does not exceed 90°, and in the initial position, the extending direction of the groove is perpendicular to the connection line of both ends of the arc-shaped trajectory; An attachment member is provided on the second surface of the base body for attaching the base body to the human body.

[0009] As an optional implementation manner of the present application, on the side surfaces of the base body and the carrier plate that are on the opposite sides, a limiting protrusion is provided on one of them, and an arc-shaped track groove is provided on the other. The center of the arc-shaped track groove coincides with the first axis; at least a part of the limiting protrusion is inserted into the arc-shaped track groove and can move in the arc-shaped track groove; the central angle formed by both ends of the arc-shaped track groove to the center does not exceed 180°, and in the initial position, the extending direction of the groove is perpendicular to the connection line of both ends of the arc-shaped track groove.

[0010] As an optional implementation manner of the present application, the attachment member includes an adhesive member fixed on the second surface of the base body, and the surface of the adhesive member away from the base body has adhesiveness; and / or the attachment member includes a strap, and both ends of the strap are adhered through a Velcro structure, and the base body is provided on the strap.

[0011] As an optional implementation manner of the present application, the fixator further includes a reminder mechanism, and the reminder mechanism includes a pressure sensor and a warning member; the pressure sensor is used to detect the pressure value from the first direction on the base body and / or the carrier plate, and the warning member is configured to emit a warning signal when the pressure value detected by the pressure sensor is greater than or equal to a set value.

[0012] As an optional implementation manner of the present application, the warning signal includes at least one of a vibration signal, an optical signal, and a sound signal that causes the fixator to vibrate.

[0013] As an optional implementation manner of the present application, the clamping member includes a first protrusion, and at least one of the two groove walls on the opposite sides of the groove is provided with the first protrusion; and / or the clamping member includes a flexible clamping block, and a slot for embedding the drainage catheter is provided on the flexible clamping block, and the clamping block is used to be embedded in the groove; in the assembled state, the drainage catheter is embedded in the slot, and the clamping block is press-fitted in the groove so that the drainage catheter is clamped in the slot.

[0014] As an alternative embodiment of the present application, the fixator further includes a cover body, which is detachably covered on the top of the carrier; an avoidance opening for avoiding the drainage catheter is provided on the side wall of the cover body.

[0015] As an alternative embodiment of the present application, a second protrusion for pressing the drainage catheter is provided on the inner wall of the cover body facing the carrier at a position corresponding to the embedding groove; and / or an identification area for identifying the information of the drainage catheter is provided on the top wall of the cover body at a position corresponding to the embedding groove.

[0016] As an alternative embodiment of the present application, a positioning portion is formed on the peripheral wall of the cover body, and a positioning groove for inserting the positioning portion along the first direction is provided on the peripheral wall of the carrier. When the positioning portion is inserted into the positioning groove, the avoidance opening is aligned with the embedding groove.

[0017] As an alternative embodiment of the present application, an elastic arm is provided on the positioning portion, a clamping step is formed on the inner side surface of the elastic arm, and a clamping groove for the clamping step to be clamped into is provided on the groove wall of the positioning groove at a position corresponding to the clamping step.

[0018] Compared with the prior art, the present application has the following beneficial effects: In the present application, a carrier capable of rotating relative to the base body is provided, and the embedding groove on the carrier is cooperated with the clamping member for clamping; thus, when fixing the drainage catheter, the drainage catheter can be clamped and fixed in the embedding groove through the clamping member, and the clamping position of the clamping member is recorded as the clamping point; the entire fixator is fixed to the patient's body or clothing through the attachment member, so that the drainage catheter is 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 exits 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 and the drainage bag connected to the drainage catheter.

[0019] Generally speaking, the first section of the aforementioned drainage catheter is generally not easily subjected to excessive pulling, and the second section of the drainage catheter is easily subjected to pulling. Since the second section of the drainage catheter is clamped at the clamping point position, even if the second section of the drainage catheter is pulled, the generated pulling force will only act on the clamping point position and will basically not act on the first section of the drainage catheter. Thus, the occurrence probability of the unplanned extubation of the drainage catheter caused by pulling is effectively reduced.

[0020] In addition, in the present application, the carrier can rotate or swing to both sides based on the initial position. Thus, when the patient lies in bed and the second section of the drainage catheter is pulled due to turning over, the carrier can rotate towards the pulled side to adapt to the pulling force, thereby playing a buffering role and reducing the pulling force generated on the clamping point.

[0021] In addition, in the design of such a rotating carrier tray, even if the drainage catheter sways left and right under the action of gravity, the rotation of the carrier tray can also freely rotate and turn accordingly, so that the drainage catheter will not slip off at the clamping point position.

[0022] Finally, in the present application, the maximum rotation angle of the carrier tray is limited, that is, the left and right rotations do not exceed 90°; with such a setting, it is possible to prevent the occurrence of the problem of unplanned extubation due to excessive rotation of the carrier tray. Specifically: if the rotation angle of the carrier tray is too large, the first section of the drainage catheter will be greatly pulled due to the rotation of the carrier tray, so that a large traction force will be generated on the first section of the drainage catheter, resulting in the problem of unplanned extubation.

[0023] It should be understood that the content described in this part is not intended to identify the key or important features of the embodiments of the present application, nor is it used 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

Specific embodiments

[0026] To make the objectives, features, and advantages of the present application more obvious and understandable, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative efforts belong to the scope of protection of the present application.

[0027] Refer to Figure 1-12 As shown, this embodiment provides a pendulum-type anti-slip surgical drainage catheter fixator, which is mainly used to fix the drainage catheter (referred to as the drainage tube) and reduce the occurrence probability of unplanned extubation. For the convenience of understanding, in this embodiment, a brief introduction to the drainage catheter is first given. Generally speaking, one end of the drainage catheter is connected to a drainage bag, and the other end is inserted into the human body for drainage. After the drainage catheter is drawn out from the human body, the drainage catheter is fixed on the skin around the drainage orifice using surgical sutures, and various new medical dressings such as medical adhesive tapes and hydrocolloid dressings are used for secondary fixation.

[0028] As Figure 1 shown, the fixator provided in this embodiment mainly includes a base body 1, a carrier tray 2, and an attachment member 4. The following is a specific description of each component: The base body 1 can be made of a hard material, such as plastic, or a flexible material, such as rubber, etc. Its shape is basically circular, or it can be other shapes, which can be selected according to actual needs; in addition, along the first direction D1, the base body 1 includes a first surface and a second surface on the opposite sides. Here, the first direction D1 can also be understood as the axial direction of the base body 1. Taking the perspective shown in the figure as an example, the top surface of the base body 1 constitutes the first surface, and the bottom surface of the base body 1 constitutes the second surface.

[0029] In some embodiments, the carrier plate 2 has a disc structure. The carrier plate 2 is disposed on the first surface of the base body 1, that is, the carrier plate 2 is disposed on the top of the base body 1, and the carrier plate 2 can rotate relative to the base body 1 about a first axis. 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.

[0030] The rotation angle of the carrier plate 2 about the first axis is limited within a certain range. Specifically, the carrier plate 2 rotates from the initial position to both sides to form an arc-shaped rotation trajectory. Combining Figure 10 As shown, this description can also be understood as follows. Taking one of the diameter lines of the carrier plate 2 as the reference line L1, the initial position of the carrier plate 2 can be understood as the initial position of this reference line L1. This reference line L1 can rotate clockwise from the initial position about the first axis to the first position, or can rotate counterclockwise from the initial position about the first axis 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, and this arc-shaped rotation trajectory can also be understood as Figure 10 the arc-shaped track groove 22 in

[0031] In addition, the maximum rotation angle of the carrier plate 2 relative to the base body 1 rotating from the initial position to both sides does not exceed 90°, that is, the maximum rotation angle of the reference line L1 from the initial position to both sides does not exceed 90°. Taking the maximum rotation angle of 90° as an example, it can be understood as follows. Taking the clock hour position as a reference, in the initial position, as Figure 10 shown, the reference line L1 points to the 6 o'clock position; the reference line L1 rotates 90° clockwise from the initial position to reach the first position, as Figure 11 shown, at this time the reference line L1 points to the 9 o'clock position; the reference line L1 rotates 90° counterclockwise from the initial position to reach the second position, as Figure 12 shown, at this time the reference line L1 points to the 3 o'clock position.

[0032] As Figure 4 shown, one or more grooves 21 for embedding a drainage catheter are provided on the carrier plate 2. The plurality of grooves 21 are arranged side by side, and the grooves 21 extend substantially in a horizontal straight line, and the top of the groove 21 is open; the specific number of the grooves 21 can be determined according to the actual number of drainage catheters to be fixed. For example, in this embodiment, the case of using 3 grooves 21 is shown, wherein one groove 21 is on the diameter line of the carrier plate 2, and the other two grooves 21 are respectively arranged side by side on both sides of the groove 21 on the diameter line.

[0033] In addition, in the initial position, as Figure 10As shown, the extending direction of the slot 21 is perpendicular to the connection line L2 between the two ends of the arc track. The extending direction of the slot 21 can also be understood as the length direction of the slot 21. Taking the above description as an example, the connection line L2 between the two ends of the arc track can also be understood as the connection line L2 between the first position and the second position. Taking the maximum rotation angle of 90° as an example, at this time, the connection line L2 between the first position and the second position is equivalent to one of the diameter lines of the carrier plate 2. When the carrier plate 2 is in the initial position, the reference line L1 is perpendicular to this diameter line.

[0034] Taking the slot 21 on the diameter line as an example, the maximum angle of rotation of this slot 21 with the turntable from the initial position in the clockwise direction is 90°, and the maximum angle of rotation in the counterclockwise direction is also 90°. A clamping member 3 for clamping the drainage catheter is provided in the slot 21.

[0035] During use, a partial pipe section of the drainage catheter is inserted into the slot 21 along the direction of the slot 21 and 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.

[0036] Since a partial pipeline of the drainage catheter extends along the length direction of the slot 21 and is clamped in the slot 21 by the clamping member 3, the position where the clamping member 3 presses the drainage catheter is equivalent to a clamping point.

[0037] The entire drainage catheter is equivalent to being divided into two sections with the clamping point of the carrier plate 2 as the boundary. The first section is the pipe section between the position where the drainage catheter exits the human body and the clamping point of the carrier plate 2, denoted as the first section of the drainage catheter; the second section is the pipe section between the clamping point of the carrier plate 2 and the drainage bag connecting the drainage catheter, denoted as the second section of the drainage catheter.

[0038] Generally speaking, the first section of the aforementioned drainage catheter is generally not easily subjected to excessive pulling, and it is the second section of the drainage catheter that is easily pulled. Since the second section of the drainage catheter is clamped at the clamping point position, even if the second section of the drainage catheter is pulled, the generated pulling force will only act on the clamping point position and will basically not act on the first section of the drainage catheter. In this way, the probability of unplanned extubation of the drainage catheter caused by being pulled is effectively reduced.

[0039] In addition, in this embodiment, the carrier plate 2 can rotate or swing to both sides based on the initial position. In this way, when the patient is in bed and the second section of the drainage catheter is pulled due to turning over activities, the carrier plate 2 can rotate towards the pulled side to adapt to this pulling force, thereby playing a buffering role and reducing the pulling force generated on the clamping point.

[0040] In addition, with such a design of the rotating carrier 2, even if the drainage catheter sways left and right under the action of gravity, the rotation of the carrier 2 can freely rotate and turn accordingly, so that the drainage catheter will not slip off at the clamping point.

[0041] In addition, it can be understood that when clamping the drainage catheter, it is necessary to ensure that there is enough margin in the first section of the drainage catheter to adapt to the maximum rotation of the carrier 2 by 90°, that is, when the carrier 2 rotates clockwise or counterclockwise to the maximum angle position, the first section of the drainage catheter will not be tensioned.

[0042] The attachment 4 in this embodiment is mainly used to attach the base 1 or the entire fixator to the human body, and the human body here can be the human skin or the clothing worn on the human body. Among them, the attachment 4 is provided on the second surface of the base 1.

[0043] In order to limit the maximum rotation angle of the carrier 2 relative to the base 1, in some embodiments, in combination Figure 5 and Figure 10 As shown, on the opposite side surfaces of the base 1 and the carrier 2, a limiting protrusion 12 is provided on one of them, and an arc-shaped track groove 22 is provided on the other. The center of the arc-shaped track groove 22 coincides with the first axis, that is, the arc-shaped track groove 22 is concentric with the carrier 2.

[0044] Specifically, as shown in the present embodiment, as Figure 5 shown, the arc-shaped track groove 22 is provided on the bottom surface of the carrier 2, as Figure 1 shown, the limiting protrusion 12 is provided on the top surface of the base 1; and at least part of the limiting protrusion 12 is inserted into the arc-shaped track groove 22 and can move in the arc-shaped track groove 22; as Figure 10 shown, the central angle formed by both ends of the arc-shaped track groove 22 to the center does not exceed 180°, preferably this central angle is 180°, that is, the connecting line L2 of both ends of the arc-shaped track groove 22 passes through the center of the carrier 2; and in the initial position, as Figure 10 shown, the extending direction of the embedding groove 21 is perpendicular to the connecting line L2 of both ends of the arc-shaped track groove 22, and it can also be understood that the extending direction of the embedding groove 21 is parallel to the aforementioned reference line L1.

[0045] In this way, it is limited that the maximum clockwise rotation angle of the carrier 2 from the initial position is 90°, and the maximum counterclockwise rotation angle is also 90°; in short, the maximum rotation angle of the carrier 2 to the left and right in the initial position is 90°.

[0046] The significance of such a setting is to prevent the occurrence of unplanned extubation caused by excessive rotation of the carrier plate 2. Specifically: if the rotation angle of the carrier plate 2 is too large, the first section of the drainage catheter will be greatly pulled due to the large-angle rotation of the carrier plate 2. In this way, a large traction force will be generated on the first section of the drainage catheter, resulting in the problem of unplanned extubation.

[0047] In some embodiments, the attachment member 4 includes an adhesive member fixed on the second surface of the base body 1, and the surface of the adhesive member away from the base body 1 has adhesiveness; for example, as Figure 2 shown, the adhesive member can be a medical dressing 41, which is made of spunlace non-woven fabric coated with medical acrylate adhesive; that is, one side of the dressing 41 is fixedly adhered to the bottom surface of the base body 1 through glue, and the other is coated with glue and covered with release paper; when in use, the release paper is torn off, and the dressing 41 is adhered to the human abdominal skin, so that the entire fixator can be fixed at the human abdominal position.

[0048] Of course, in some other alternative embodiments, in combination with Figure 3 shown, the attachment member 4 can also be a strap 42, preferably an elastic strap 42; the two ends of the strap 42 are adhered through a Velcro structure, and the Velcro structure mainly includes a first part with a fuzzy surface and a second part with a hook-and-spine surface that can adhere to the fuzzy surface. The first part and the second part are respectively provided at the two ends of the strap 42; and the base body 1 is fixed on the strap 42. In this way, when in use, the strap 42 can be strapped and worn at the human abdominal position, so that the entire fixator can also be fixed at the human abdominal position.

[0049] Of course, the attachment member 4 can also be a combination of the aforementioned dressing 41 and the strap 42, as Figure 3 shown, the base body 1 is adhered to the strap 42 through the dressing 41. In this way, after use, the entire fixator can be removed from the strap 42.

[0050] In some embodiments, the clamping member 3 includes one or more. Specifically, the clamping member 3 includes a first protrusion 31, and the first protrusion 31 can be made of plastic or rubber.

[0051] As Figure 4 shown, on the two side walls of the opposite sides of the slot 21, at least one of them is provided with the first protrusion 31. Preferably, the first protrusions 31 are arranged oppositely on the two side walls of the slot 21, and the drainage catheter is clamped in the slot 21 by the first protrusions 31 on both sides together.

[0052] In practical applications, some drainage catheters may not be able to be clamped by the first protrusion 31 due to their too small own diameter; thus, in some embodiments, as Figure 4As shown, the clamping member 3 further includes a flexible clamping block 32, such as a clamping block 32 made of rubber material; a card slot 321 for embedding the drainage catheter is formed on the flexible clamping block 32, so that the whole clamping block 32 is generally in a U-shaped structure.

[0053] 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 card slot 321, and the clamping block 32 is press-fitted in the embedding groove 21 so that the drainage catheter is clamped in the card slot 321. That is, when the clamping block 32 is embedded in the embedding groove 21, the two sides of the clamping block 32 will be squeezed to gather towards the middle, so that the side walls on both sides of the clamping block 32 will hold the embedded drainage catheter tightly; in this way, the clamping of the drainage catheter is realized.

[0054] Among them, the clamping block 32 can be one or more. As a spare part, the clamping block 32 can be designed in a variety of different model sizes to respectively correspond to different size models of drainage catheters.

[0055] In order to prevent the part of the drainage catheter embedded in the embedding groove 21 from being accidentally squeezed, in some embodiments, as Figure 1 shown, the fixator further includes a cover body 5, and the cover body 5 is detachably covered on the top of the carrier plate 2. For example, the cover body 5 is covered on the top of the carrier plate 2 in the form of snap connection or screw connection.

[0056] In addition, in order to enable the drainage catheter to pass through the cover body 5 smoothly, in some embodiments, an avoidance opening 51 for avoiding the drainage catheter is formed on the side wall of the cover body 5. In this way, the presence of the cover body 5 can form a block for the part of the drainage catheter embedded in the embedding groove 21 to prevent this part of the pipe section from being accidentally squeezed.

[0057] In addition, in order to further improve the fixing effect on the drainage catheter, in some embodiments, as Figure 8 shown, a second protrusion 52 for pressing the drainage catheter is provided on the inner wall of the cover body 5 facing the carrier at the position corresponding to the embedding groove 21. In this way, after the cover body 5 is covered, the second protrusion 52 will generate a pressing force towards the carrier plate 2 on the drainage catheter. In this way, with the clamping of the first protrusion 31, the two are clamped together, thus improving the fixing effect.

[0058] In some embodiments, as Figure 2 shown, an identification area 53 for identifying the information of the drainage catheter is provided on the top wall of the cover body 5 at the position corresponding to the embedding groove 21. One identification area 53 corresponds to one embedding groove 21, and the identification area 53 is directly above the corresponding embedding groove 21; the identification area 53 here can be an adhesive and replaceable identification paper attached to the cover body 5, and the identification information is recorded on the identification paper, and the identification information includes the name of the drainage catheter, the length of the drainage catheter, the indwelling time, etc.

[0059] In this embodiment, taking the case where the cover 5 is covered on the top of the carrier 2 in a snap - fit manner as an example, the specific description is as follows: As Figure 9 shown, a positioning portion 54 is formed on the peripheral wall of the cover 5. The specific formation of the positioning portion 54 can be that a part of the peripheral wall of the cover 5 bulges inward; as Figure 4 shown, a positioning groove 23 for the positioning portion 54 to be inserted along the first direction D1 is provided on the peripheral wall of the carrier 2. 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 5, ensuring that the avoidance opening 51 and the embedding groove 21 can be aligned and the two are not misaligned.

[0060] As Figure 9 shown, an elastic spring arm 541 is provided on the positioning portion 54, and a clamping step 542 is formed on the inner side surface of the spring arm 541 (the side surface of the spring arm 541 facing the carrier 2); as Figure 4 shown, a clamping groove 231 for the clamping step 542 to be clamped into is provided on the groove wall of the positioning groove 23 at the position corresponding to the clamping step 542; when the positioning portion 54 of the cover 5 is aligned with the positioning groove 23 and continuously inserted downward, as Figure 6 and Figure 7 shown, when the clamping progresses to the position of the clamping groove 231, under the elastic force of the spring arm 541, the clamping step 542 will be clamped into the clamping groove 231, thereby realizing clamping and fixing, and thus the cover 5 is clamped on the carrier 2.

[0061] In some embodiments, in order to be able to drive the clamping step 542 to escape from the clamping groove 231 to achieve unlocking, a dial 543 is provided on the outer wall of the spring arm 541. When unlocking is required, just use a finger to pull the dial 543 to move outward, which can drive the spring arm 541 to move outward, and then the clamping step 542 can escape from the clamping groove 231 to achieve unlocking.

[0062] In addition, when the patient lies in bed wearing the fixator, if the patient turns over into a prone sleeping position, the patient is very likely to press on the drainage catheter, thus causing extrusion of the drainage catheter and affecting the drainage effect. Based on this, in some embodiments, in order to be able to remind the patient to change the sleeping position, the fixator is further improved: The fixator further includes a reminder mechanism, and the reminder mechanism 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 from the first direction D1 received by the base 1 and / or the carrier 2, and the warning member is configured such 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 issue a warning signal.

[0063] Specifically, the pressure sensor 6 can be arranged on the top surface of the cover body 5 or at the position between the attachment member 4 and the base body 1; the pressure sensor 6 can be arranged inside the base body 1; in addition, a storage battery for supplying power to the pressure sensor 6 and the controller can be arranged inside the base body 1, or it can be directly connected to the mains power supply to supply power to the pressure sensor 6 and the controller, which is not specifically limited herein. The controller can be arranged inside the base body 1.

[0064] In this way, when the patient presents a prone sleeping position, the entire fixator will be pressed under the body, thereby generating a pressure on the fixator. This 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 member to emit a warning signal to remind the patient or medical staff.

[0065] The warning signal includes at least one of a vibration signal, a light signal, and a sound signal that cause the fixator to vibrate. Specifically, the generation of the vibration signal can be achieved by arranging a vibration motor (not shown in the figure) inside the base body 1, and driving the fixator to vibrate through the vibration of the motor to form a vibration signal to remind the patient. It can also be achieved by arranging a buzzer on the base body 1 to form a sound signal through the buzzing of the buzzer, or by arranging a signal lamp on the base body 1 to generate a light signal through the lighting of the signal lamp. Specifically, the specific warning signal can be selected according to actual needs, and preferably it is a vibration signal.
