Description

An alarm device for preventing catheter slippage Technical Field

[0001] This invention relates to the field of catheter technology, and in particular to an alarm device for preventing catheter slippage. Background Technology

[0002] In clinical practice, slippage of exposed catheters such as gastric tubes, central venous catheters, and thoracic and abdominal drainage tubes is a common and dangerous adverse event. Catheter slippage can lead to serious complications such as reflux aspiration, bleeding, infection, pneumothorax, and drainage leakage, increasing patient suffering and medical risks, while also increasing the workload of medical staff. Currently, clinical practice relies heavily on passive protection methods such as tape fixation and restraint straps, lacking proactive warning and immediate remedial capabilities. It is impossible to predict or perceive the catheter situation, and medical staff may not be able to detect slippage in time, missing the best opportunity for treatment. This directly leads to fatal complications such as reflux aspiration, air embolism, and pneumothorax. Moreover, there is no automatic blocking or protective action after slippage, and the dangers of gastric tube reflux, central venous catheter air intake, and drainage tube leakage occur directly, significantly increasing the medical risks of infection, bleeding, and respiratory failure, exacerbating patient suffering and the difficulty of treatment.

Detailed Implementation

[0027] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0028] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0029] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments.

[0030] Example 1, referring to Figures 1-3, is the first embodiment of the present invention. This embodiment provides an alarm device for preventing catheter slippage. The alarm device for preventing catheter slippage includes an alarm component 1, including a fixing frame 11. The fixing frame 11 is bonded to the patient's catheter by an adhesive base. There are two clamps 12 inside the fixing frame 11, located on both sides inside the fixing frame 11. The catheter is clamped by the two clamps 12, so that the clamps 12 are connected to the catheter. When the catheter moves, the clamps 12 can be moved.

[0031] A threaded post 13 is fixed on one side of the clamping plate 12. A threaded sleeve 14 is threadedly connected to the outside of the threaded post 13. A through groove 11-1 is provided on the fixing frame 11. The threaded sleeve 14 is movably connected to the through groove 11-1. By rotating the threaded sleeve 14, the threaded post 13 and the clamping plate 12 can be moved, thereby adjusting the distance between the two clamping plates 12 and adapting to different specifications of conduit diameters.

[0032] A positioning ring 15 is fixed on the outside of the threaded sleeve 14. There are two positioning rings 15, which are fixed at both ends of the outside of the threaded sleeve 14 and located on both sides of the side wall of the fixed frame 11. They are used to position the threaded sleeve 14 and prevent the threaded sleeve 14 from moving axially.

[0033] A sound and light alarm 16 is fixed on one side of the fixed frame 11. A trigger switch is provided on one side of the sound and light alarm 16. When the trigger switch is touched, the sound and light alarm 16 will emit a sound and light alarm, thereby reminding medical staff.

[0034] The clamp 12 is annular and has anti-slip spikes 12-1 fixed on its inner side. The anti-slip spikes 12-1 are inclined and have pointed cone-shaped ends. The anti-slip spikes 12-1 are made of relatively soft positioning material to increase the friction between the clamp 12 and the catheter, so that when the catheter moves, it can promptly drive the clamp 12 to move without the clamp 12 applying excessive squeezing force to the catheter.

[0035] A pull rope 17 is fixed to one side of the threaded post 13, and the other end of the pull rope 17 is fixed to the inner wall of the fixed frame 11. The pull rope 17 is elastic and is used to apply tension to the threaded post 13 so that the threaded post 13 and the clamping plate 12 can be kept in the current position.

[0036] A positioning plate 18 is fixed to the top of the clamping plate 12. A positioning post 19 is provided on the positioning plate 18. There are two positioning plates 18, which are fixed to the two clamping plates 12 respectively. The positioning post 19 is fixed to one of the positioning plates 18 and is movably connected to the other positioning plate 18. The two cooperate to guide and position the two clamping plates 12, so as to prevent the clamping plates 12 from shifting when adjusting the distance.

[0037] When the catheter slips out during use, it will cause the clamp 12 to move. The clamp 12 will then cause the threaded post 13 and the threaded sleeve 14 to move. At this time, the threaded sleeve 14 will slide in the through groove 11-1 and cause the positioning ring 15 to contact the trigger switch of the audible and visual alarm 16. The audible and visual alarm 16 will then emit an audible and visual alarm, which can remind medical staff to be aware of the slippage danger as soon as possible and rush to deal with it. This will prevent the complications from continuing to develop due to the delay in the discovery of slippage and greatly shorten the response time for the danger.

[0038] Example 2, referring to Figures 2, 4, 6 and 7, is the second embodiment of the present invention, which is based on the previous embodiment.

[0039] Specifically, it also includes a clamping assembly 2, which is set in the fixed frame 11 and includes clamping elements 21. There are two sets of clamping elements 21, which are located on one side of the two clamping plates 12 respectively. The clamping element 21 includes a squeezing plate 211 located on one side of the clamping plate 12. The squeezing plate 211 is vertical. The squeezing plate 211 is used to clamp and seal the catheter, thereby preventing serious complications such as reflux aspiration, air embolism, pneumothorax, drainage fluid leakage, bleeding and infection, reducing the patient's medical risks and suffering, and reducing the workload of medical staff.

[0040] A positioning frame 212 is fixed to one side of the clamping plate 12. The positioning frame 212 is L-shaped. A fixing rod 213 is fixed to one side of the squeezing plate 211. The fixing rod 213 is movably connected to the positioning frame 212. The two work together to support and position the squeezing plate 211. The squeezing plate 211 can move with the adjustment of the spacing of the clamping plate 12, so that the squeezing force applied by the squeezing plate 211 to the conduit is moderate. This avoids the situation where the squeezing force applied to the conduit is too tight and damages the conduit, or too loose and cannot effectively stop the flow due to different conduit diameters.

[0041] A protective pad 211-1 is fixed on one side of the extrusion plate 211. When the extrusion plate 211 extrudes the conduit, the protective pad 211-1 can protect the conduit and prevent the conduit from being damaged due to the extrusion plate 211 being too hard.

[0042] A fixing block 214 is fixed to the end of the fixing rod 213. A first spring 215 is fixed to one side of the fixing block 214. The other end of the first spring 215 is fixed to the positioning frame 212. The first spring 215 is in a stretched state and is used to apply tension to the fixing block 214. The fixing rod 213 and the extrusion plate 211 are moved through the fixing block 214, so that the extrusion plate 211 can clamp and seal the conduit.

[0043] The clamping assembly 2 also includes a locking element 22, which includes a locking block 221. One side of the locking block 221 is inclined. A movable groove 213-1 is provided in the fixing rod 213. The locking block 221 is located in the movable groove 213-1. A slot 212-1 is provided on the positioning frame 212. The locking block 221 engages with the slot 212-1. The two work together to lock the positions of the fixing rod 213 and the pressing plate 211, so that when the pressing plate 211 is in the current position, it will not clamp the conduit due to the elastic force of the first spring 215, thus avoiding affecting the normal use of the conduit.

[0044] A second spring 222 is fixed on one side of the locking block 221, and the other end of the second spring 222 is fixed to the inner wall of the movable groove 213-1. The second spring 222 is used to apply a pushing force to the locking block 221, so that the locking block 221 and the groove 212-1 are engaged more securely.

[0045] A push rod 223 is inserted into the slot 212-1, and a baffle 224 is fixed on the inner wall of the fixed frame 11. The end of the push rod 223 contacts the card block 221, and the baffle 224 is located at the outlet of the fixed frame 11.

[0046] When in use, the movement of the clamping plate 12 will simultaneously drive the compression plate 211 to move. When the audible and visual alarm 16 is triggered, the push rod 223 will contact the baffle 224. At this time, the baffle 224 will apply a reverse thrust to the push rod 223, causing it to push the locking block 221 to separate from the locking groove 212-1, thereby releasing the locking of the fixing rod 213 and the compression plate 211. At this time, the first spring 215 will apply a pulling force to the fixing block 214, and through the fixing block 214, drive the fixing rod 213 and the compression plate 211 to move, so that the compression plate 211 clamps and seals the catheter, thereby preventing serious complications such as reflux aspiration, air embolism, pneumothorax, drainage fluid leakage, bleeding and infection, reducing the patient's medical risks and pain, and reducing the workload of medical staff.

[0047] Example 3, referring to Figures 4 and 5, is the third embodiment of the present invention, which is based on the first two embodiments.

[0048] The clamping assembly 2 also includes a rotating component 23, which includes a support block 231 fixed to the top of the positioning frame 212. A fixing post 232 is fixed to one side of the support block 231, and a stabilizing block 233 is fixed to the top of the fixing block 214. A rotating sleeve 234 is rotatably connected to the stabilizing block 233 through a bearing. The rotating sleeve 234 is sleeved on the outside of the fixing post 232. A spiral groove 232-1 is opened on the fixing post 232. A fixing shaft 235 is fixed inside the rotating sleeve 234. The fixing shaft 235 slides in the spiral groove 232-1. When the rotating sleeve 234 rotates, it will drive the fixing shaft 235 to slide in the spiral groove 232-1. Through the cooperation of the two, the rotating sleeve 234 and the stabilizing block 233 will move, and the stabilizing block 233 will drive the fixing block 214 and the fixing rod 213 to move, so that the fixing rod 213 can drive the extrusion plate 211 to move.

[0049] A rotating rod 236 is fixed to the end of the rotating sleeve 234. A moving rod 237 is provided on one side of the fixed block 214. A connecting shaft 238 is fixed to the end of the moving rod 237. A sliding groove 236-1 is provided on the rotating rod 236. The connecting shaft 238 slides in the sliding groove 236-1. A push plate 239 is fixed to the inner wall of the fixed frame 11. A stabilizing frame 230 is fixed to one side of the fixed block 214. The moving rod 237 is movably connected to the stabilizing frame 230.

[0050] In use, after adjusting the position of the slip-out guide tube, push the clamping plate 12 to move into the fixed frame 11. At this time, the clamping plate 12 will drive the pressing plate 211 to move, and the pressing plate 211 will drive the end of the moving rod 237 to contact the push plate 239. At this time, the push plate 239 will apply a reverse thrust to the moving rod 237. The moving rod 237 will drive the rotating rod 236 and the rotating sleeve 234 to rotate through the cooperation of the connecting shaft 238 and the slide groove 236-1. When the rotating sleeve 234 rotates, it will drive the fixed shaft 235 to slide in the spiral groove 232-1. Through the cooperation of the two, the rotating sleeve 234 and the stabilizing block 233 will move. The device moves, and through the stabilizing block 233, it drives the fixed block 214 and the fixed rod 213 to move, thereby allowing the fixed rod 213 to drive the squeezing plate 211 to move and separate the squeezing plate 211 from the conduit. When the squeezing plate 211 stops moving, the locking block 221 will coincide with the locking groove 212-1. At this time, the second spring 222 applies a pushing force to the locking block 221, causing the locking block 221 to engage with the locking groove 212-1. Through the cooperation of the two, the positions of the fixed rod 213 and the squeezing plate 211 can be locked, so that the squeezing plate 211 will not clamp the conduit due to the elastic force of the first spring 215 when it is in the current position, thus avoiding affecting the normal use of the conduit.

Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
