Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a drainage tube clamp. Background Art

[0002] Drainage tubes are commonly used in medical drainage. One end of the drainage tube is inserted into the human body, and the other end is connected to a drainage bag. The fluid in the human body flows into the drainage bag through the drainage tube. When replacing the drainage bag, the drainage tube needs to be closed first to prevent air from entering the human body through the drainage tube. Figure 1 As shown in the figure, the opening and closing of the drainage tube is controlled by pushing the drainage tube to the through hole and the narrow slit. However, when the sheet-type drainage tube clamp is pushed, the drainage tube clamp is almost perpendicular to the drainage tube and lacks support on the left and right sides. As a result, the sheet-type drainage tube clamp is prone to tilting to both sides, causing inconvenience in operation. Utility Model Content

[0003] The purpose of the utility model is to provide a drainage tube clamp to address the deficiencies of the prior art.

[0004] The specific technical solutions are as follows:

[0005] A drainage tube clamp, comprising:

[0006] An arc-shaped plate and a U-shaped plate, the two ends of the arc-shaped plate are respectively fixedly connected to the two ends of the U-shaped plate to form an annular structure; a first through hole and a narrow slit are provided on the arc-shaped plate, the first through hole and the narrow slit are smoothly connected, and the drainage tube slides freely between the through hole and the narrow slit; a second through hole is provided at the bottom of the U-shaped plate, and the sides of the first through hole and the second through hole are respectively provided with entrances for the drainage tube to enter.

[0007] Optionally, a first reinforcing plate is provided on a side of the bottom of the U-shaped plate opposite to the inlet, and the first reinforcing plate is used to compensate for the weakening effect of the setting of the inlet on the overall structural strength.

[0008] Optionally, a second reinforcing plate is provided at the connection between one end of the arc-shaped plate with the narrow slit and the U-shaped plate. The second reinforcing plate is used to compensate for the weakening effect of the entrance setting on the overall structural strength, and the second reinforcing plate connects the arc-shaped plate and the U-shaped plate at the same time.

[0009] Optionally, anti-slip grooves are provided on the outer sides of both ends of the U-shaped plate.

[0010] Optionally, the arc-shaped plate and the U-shaped plate form a channel in which a drainage tube can be pre-installed.

[0011] Optionally, the first reinforcement plate and the second reinforcement plate are fixed to the U-shaped plate and the arc-shaped plate by welding or bolting.

[0012] Optionally, the anti-slip grooves are arranged continuously or at intervals to provide a stable grip and operating experience.

[0013] Optionally, the drainage tube clamp is made of medical-grade plastic or silicone.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] (1) The utility model forms a stable support structure by fixedly connecting the arc plate and the U-shaped plate. When the drainage tube clamp is in operation, it is not only supported by the four fingers and the U-shaped plate in the longitudinal direction, but also not easily tilted in the transverse direction due to the width of the arc plate, thereby ensuring the stability of the operation; the U-shaped plate bottom side opposite to the inlet and the end of the arc plate with a narrow slit at the connection with the U-shaped plate are both provided with reinforcement plates, which effectively compensate for the weakening effect of the inlet on the overall structural strength, so that the drainage tube clamp is more stable and not easily deformed when subjected to external force;

[0016] (2) The drainage tube clamp of the present invention can be pre-installed on the drainage tube, and can also be used on a pipe without a pre-installed drainage tube clamp, which increases the flexibility of use. The operator can hold the drainage tube with four fingers and use the thumb to control the sliding of the drainage tube between the first through hole and the narrow slit, or hold the drainage tube clamp with four fingers and swing the drainage tube with the index finger or thumb. Both gestures can be used in both directions, which improves the convenience and adaptability of operation. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features therein can be combined with each other.

[0022] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, but they are not intended to limit the present invention.

[0023] The utility model provides a drainage tube clamp, referring to Figure 2 , including: an arc-shaped plate 1 and a U-shaped plate 2, the two ends of the arc-shaped plate 1 are respectively fixedly connected to the two ends of the U-shaped plate 2 to form an annular structure, which provides lateral support for the control of the drainage tube and prevents the drainage tube clamp from tilting to both sides during operation; a first through hole 3 and a narrow slit 4 are provided on the arc-shaped plate 1, and the first through hole 3 and the narrow slit 4 are smoothly connected to form a sliding path for the drainage tube, and the opening and closing of the drainage tube is controlled by adjusting the sliding position of the drainage tube between the first through hole 3 and the narrow slit 4; a second through hole 5 is provided at the bottom of the U-shaped plate 2, which provides longitudinal support for the fixation and control of the drainage tube, and the sides of the first through hole 3 and the second through hole 5 are respectively provided with an entrance 6 for the drainage tube to enter, which facilitates the insertion and removal of the drainage tube, ensuring that the drainage tube can be quickly and accurately positioned between the through hole and the narrow slit 4.

[0024] Reference Figure 2 Specifically, in this embodiment, the arc plate 1 is fixedly connected to both ends of the U-shaped plate 2 to form a stable annular structure, which provides all-round support for the drainage tube clamp and effectively prevents the drainage tube clamp from tilting during operation; the smooth transition design of the first through hole 3 and the narrow slit 4 enables the drainage tube to transition smoothly during the sliding process, reduces the resistance during operation, and improves the convenience of operation; the setting of the inlet 6 enables the drainage tube to be quickly and accurately inserted into the first through hole 3 or the narrow slit 4, thereby realizing rapid positioning and control of the drainage tube. Among them, the operator can hold the drainage tube with four fingers, push the drainage to the first through hole 3 or the narrow slit 4, and adjust the position of the drainage tube between the through hole and the narrow slit 4 to realize the opening and closing control of the drainage tube; and due to the annular structure design composed of the arc plate 1 and the U-shaped plate 2, it provides horizontal and vertical support, ensures the stability of the drainage tube clamp during operation, effectively prevents the drainage tube clamp from tilting, and improves the convenience and safety of operation. The utility model effectively solves the problem that the existing sheet-type sliding clamp is easy to tilt during operation, and improves the stability of drainage tube control and the convenience of operation.

[0025] In this device, refer to Figure 2 A first reinforcement plate 7 is installed on the bottom side of the U-shaped plate 2, opposite the inlet 6. The material and thickness of the first reinforcement plate 7 match the U-shaped plate 2, ensuring structural integrity and strength. The size and shape of the first reinforcement plate 7 are designed to compensate for the weakening of the U-shaped plate 2's overall structural strength caused by the inlet 6. By increasing the support force in this area, the drainage tube clamp's stability and durability are improved.

[0026] Specifically, refer to Figure 2A second reinforcing plate 8 is provided at the connection between one end of the curved plate 1 with the narrow slit 4 and the U-shaped plate 2. Similarly, the material and thickness of the second reinforcing plate 8 match the curved plate 1 and the U-shaped plate 2, ensuring the overall strength of the structure. The size and shape design of the second reinforcing plate 8 are intended to compensate for the weakening of the structural strength of the connection between the curved plate 1 and the U-shaped plate 2 caused by the setting of the inlet 6. By increasing the supporting force of the connection, the stability and durability of the drainage tube clamp are further improved. The second reinforcing plate 8 connects the curved plate 1 and the U-shaped plate 2 at the same time, ensuring that the drainage tube clamp can maintain structural stability and safety when subjected to external force or drainage tube pressure, thereby extending its service life.

[0027] Reference Figure 2 , anti-slip grooves 9 are provided on the outer sides of both ends of the U-shaped plate 2, and their design takes into account the contact area and friction requirements of the operator when gripping. The depth and spacing of the anti-slip grooves 9 have been optimized to ensure that the operator can obtain sufficient friction when gripping, and can maintain a stable grip even when the hands are wet or wearing gloves. By increasing the friction, the anti-slip grooves 9 effectively prevent the drainage tube clamp from sliding in the operator's hands when adjusting the opening and closing of the drainage tube, thereby improving the accuracy and safety of the operation. Especially in emergency medical operations or those that require high concentration, the provision of anti-slip grooves 9 can significantly reduce operational errors caused by sliding, ensuring the smooth progress of the medical process. The drainage tube clamp of the present invention not only enhances the structural stability by providing the first reinforcement plate 7 and the second reinforcement plate 8, but also further improves the operational stability by providing anti-slip grooves 9 on the outer sides of both ends of the U-shaped plate 2. Combined with these structural designs, the drainage tube clamp of the present invention not only ensures structural strength, but also provides a better operating experience and improves the convenience of use.

[0028] Specifically, the anti-slip grooves 9 are arranged continuously or at intervals to provide a stable grip and operating experience. The anti-slip grooves 9 can be arranged continuously, forming a continuous textured surface that provides uniform friction, suitable for scenarios requiring continuous and stable grip; or they can be arranged at intervals, forming a series of independent grooves. This arrangement can reduce hand discomfort during prolonged grip and is suitable for scenarios requiring intermittent grip. Whether arranged continuously or at intervals, the anti-slip grooves 9 can significantly increase the friction when the operator grips the device, providing a stable grip even with wet hands or wearing gloves, reducing operational errors caused by slippage and improving safety.

[0029] Specifically, refer to Figure 2The curved plate 1 and the U-shaped plate 2 form a channel for pre-installed drainage tubes. This channel's structural design allows for stable movement of the tube along a pre-set path after insertion, eliminating the need for repositioning between uses and significantly simplifying the operation process. The tube can be quickly positioned and secured within this pre-installed channel. The operator simply inserts the tube into the inlet 6 and then moves it along the second through-hole 5 to the first through-hole 3 or the narrow slit 4 to complete positioning and opening and closing of the tube.

[0030] The first and second reinforcing plates 7, 8 are secured to the U-shaped plate 2 and curved plate 1 by welding or bolting. Welding provides a high-strength connection, ensuring a secure bond between the reinforcing plates and the main structure, effectively enhancing the overall stability of the structure. Bolting provides a removable connection for easy maintenance and replacement. While ensuring structural strength, bolting also provides flexibility, facilitating adjustment or replacement of the reinforcing plates to suit different usage requirements.

[0031] Drainage tube clamps are made of medical-grade plastic or silicone. Medical-grade plastic offers high chemical resistance, resisting corrosion from common disinfectants and cleaning agents in medical environments. It also offers excellent durability, extending the life of the device. Medical-grade plastic is lightweight and easy to handle, and can be molded into complex shapes to meet design requirements. Silicone is soft and flexible, adapting to drainage tubes of varying diameters, ensuring a tight closure and preventing fluid leakage.

[0032] Working principle: The drainage tube clamp of the present invention can be pre-installed on the drainage tube, and can also be used on a pipe without a pre-installed drainage tube clamp. When used on a pipe without a pre-installed drainage tube clamp, the operator can pinch the drainage tube flat and place it into the channel formed by the U-shaped plate 2 and the curved plate 1 from the inlet 6. When in use, the operator can hold the drainage tube with four fingers, with the curved plate 1 of the drainage tube clamp against the index finger, and press the thumb on the anti-slip groove 9 on the outside of the U-shaped plate 2 to slide the drainage tube between the first through hole 3 and the narrow slit 4. Due to the longitudinal support of the four fingers and the U-shaped plate 2, and the lateral support of the curved plate 1, the drainage tube clamp is not easy to tilt during operation, and the operation is more stable. In addition to the above-mentioned operating method, the operator can also hold the drainage tube clamp with four fingers, with the curved plate 1 located on the side of the index finger, and use the index finger or thumb to swing the drainage tube to achieve the opening and closing control of the drainage tube. This operating method is also stable and suitable for operators with different operating habits. The present invention's drainage tube clamp significantly enhances operational stability and convenience through its innovative structural design, including the combination of the curved plate 1 and the U-shaped plate 2, the provision of a reinforcement plate, and the addition of anti-slip grooves 9. Whether used pre-assembled or not, it ensures precise control of the drainage tube during medical drainage procedures, reduces operational errors, and improves the safety and efficiency of medical procedures.

[0033] The above are only preferred embodiments of the present invention and do not limit the implementation methods and protection scope of the present invention. Those skilled in the art should be aware that all solutions obtained by equivalent substitutions and obvious changes made using the description and illustrations of the present invention should be included in the protection scope of the present invention.
