Description

Technical Field

[0001] This utility model relates to the field of medical devices, specifically to an infusion tube anti-dislodgement device. Background Technology

[0002] In medical and nursing practice, intravenous infusion therapy is a common and important treatment method, widely used in the treatment and rehabilitation of various diseases. In traditional infusion methods, the infusion tubing is often directly exposed, making it susceptible to interference from patient activity, changes in body position, or external factors. Although medical staff take certain measures to secure it, accidental dislodgement of the infusion tubing still occurs from time to time.

[0003] The prior art disclosed in patent publication (announcement) number CN218458406U is an infusion tube anti-dislodgement device, including a mounting frame. A first threaded rod and a second threaded rod are rotatably connected to the mounting frame. The first threaded rod is fixedly connected to the second threaded rod. The other ends of the first threaded rod and the second threaded rod are respectively rotatably connected to the inner walls of the two sides of the mounting frame. The bottom of the first threaded rod passes through the mounting frame and is fixedly connected to a handle. The outer walls of the first threaded rod and the second threaded rod are each fitted with a U-shaped frame that is threadedly connected to them. Each of the two U-shaped frames is fixedly connected to a sliding block.

[0004] The aforementioned patent document discloses an infusion tube anti-dislodgement device, which can solve the problem of some patients being agitated or restless and unable to control themselves, pulling on the infusion tube, causing the infusion set to detach from the sealed sterile rehydration container, making the infusion set unusable and requiring replacement, thus indirectly increasing the patient's treatment costs. However, it has the following drawbacks:

[0005] When using the aforementioned device, the screw adjustment structure requires medical staff to operate it with both hands. The entire adjustment process is cumbersome, not only consuming a lot of time and energy, but also easily delaying the patient's optimal treatment time due to excessive operation time. Furthermore, the threaded components will inevitably experience metal fatigue during long-term and frequent rotation. As the usage time increases, its clamping force will gradually decrease, which will undoubtedly significantly increase the risk of the infusion tube falling off, posing a safety hazard to the patient's treatment.

[0006] Therefore, we have made improvements to this and proposed an infusion tube anti-dislodgement device. Utility Model Content

[0007] To address the shortcomings of existing technologies, this utility model provides an infusion tube anti-dislodgement device, which solves the problems mentioned in the background art.

[0008] To achieve the above-mentioned objectives, this utility model provides the following technical solution:

[0009] An infusion tube anti-dislodgement device is used to solve the above problems.

[0010] The application is as follows:

[0011] The device includes an infusion bottle, an infusion tube is provided on the lower side of the infusion bottle, and a puncture device is fixedly installed on the top end of the infusion tube. A connecting block is provided on the outer side of the infusion tube, and a groove is provided on the surface of the connecting block. A blocking mechanism is provided on the inner wall of the groove. A connecting mechanism is provided between the connecting block and the infusion bottle.

[0012] The blocking mechanism includes a slot, and there are two slots. The two slots are respectively opened on the inner walls of the two sides of the groove. A stop block is slidably connected inside the slot, and a spring is fixedly installed between one end of the stop block and the inner wall of the slot. The other end of the stop block is arc-shaped.

[0013] As a preferred technical solution of this application, the connecting mechanism includes connecting members, and two connecting members are provided. The two connecting members are respectively fixedly installed on both sides of the upper surface of the connecting block. A rotating rod is connected inside the connecting member, and a connecting rod is slidably connected inside the rotating rod. The connecting rod is curved, and an arc-shaped rod is fixedly installed at the other end of the connecting rod.

[0014] As a preferred technical solution of this application, the rotating rod has a sliding groove inside, and the connecting rod and the rotating rod are connected by a sliding connection. A limit block is slidably connected inside the sliding groove, and the limit block is connected to the connecting rod by a fixed connection. A tension spring is fixedly installed between the limit block and the inner wall of the sliding groove.

[0015] As a preferred technical solution of this application, an installation rod is fixedly installed at the bottom end of the rotating rod, and slots are provided on both sides of the inner wall of the connector, and the installation rod is rotatably connected in the slots, thus forming a rotating structure between the rotating rod and the connector.

[0016] As a preferred technical solution of this application, an installation groove is provided on the outer side of the middle part of the card slot, and a coil spring is fixedly installed inside the installation groove, and the inner ring of the coil spring is fixedly installed on the outside of the installation rod.

[0017] As a preferred technical solution of this application, the puncture device is inserted into the infusion bottle, and the infusion tube is set in the groove on the surface of the connecting block.

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0019] In the scheme of this application:

[0020] 1. By using the blocking mechanism, infusion tubes of different diameters can be placed in the groove. The groove openings on both sides of the inner wall are slidably connected to the stop blocks. One end of the stop block is connected to the inner wall of the groove opening by a spring, and the other end is set in an arc shape. When the infusion tube is pulled by an external force, the stop block will block the infusion tube under the action of the spring, preventing it from sliding out of the connecting block. This greatly reduces the risk of the infusion tube falling off due to patient activity or external interference, and ensures the smooth progress of infusion therapy.

[0021] 2. Through the use of the connecting mechanism, the rotating rod can rotate flexibly within the connector. Combined with the rotating connection of the mounting rod within the slot and the coil spring, the connection between the connecting block and the infusion bottle is both stable and flexible, adapting to different usage scenarios and changes in patient positioning. Furthermore, the coil spring allows the connecting block to automatically reset after rotation, maintaining the stability of the device. Simultaneously, the sliding connection of the internal rotating rod and the buffering and resetting effect of the tension spring further enhance the stability and durability of the device. This design avoids the cumbersome, time-consuming, and labor-intensive operation of traditional screw adjustment structures, eliminating the need for medical personnel to operate with both hands, greatly improving the efficiency of installation and adjustment. Especially in emergency treatment scenarios, it can prevent delays in the patient's optimal treatment time due to excessive operation time. Attached Figure Description
