Description

Technical Field

[0001] The utility model belongs to the technical field of medical three-way infusion tubes, and particularly relates to a fixing device for a medical three-way tube for monitoring water leakage. Background Art

[0002] A three-way tube refers to a pipe joint with three openings, which is widely used in pipe networks for transporting liquids or gases. Therefore, it is also very commonly used in a medical environment. For example, the patent with the publication number CN209884907U discloses a fixing device for a medical three-way infusion tube. The infusion tubes are connected together through a three-way joint for intravenous injection or infusion and blood transfusion of patients. By fixing the three-way joint and separating the infusion tubes, problems such as the pulling of the three-way tube on the central venous catheter causing the film to come off and the infusion tubes being entangled with each other are solved.

[0003] However, the three-way tubes in the prior art cannot ensure the sealing effect of the connection between the three-way joint and the infusion tube. In actual use, the problem of liquid leakage may occasionally occur. When this happens during the night or when a patient is receiving infusion without company, it may lead to the loss of expensive drugs. If the liquid leakage cannot be detected in time and too much liquid is lost, it may affect the dosage of the patient's medication and lead to serious consequences such as ineffective treatment. Content of the Utility Model

[0004] The technical problem to be solved by the utility model is to provide a fixing device for a medical three-way tube for monitoring water leakage, which can automatically remind medical staff in time if the problem of liquid leakage occurs while fixing the three-way tube and separating the infusion tubes.

[0005] The technical solution adopted by the utility model to solve its technical problems is: to provide a fixing device for a medical three-way tube for monitoring water leakage, including a housing with infusion tube connection holes opened on its surface. A sliding cover is slidably connected to the upper part of the housing. A U-shaped gasket for limiting the three-way tube is arranged below the sliding cover. A collecting plate with several water guide grooves is arranged below the gasket. The water outlet of the water guide groove communicates with a water box arranged below the gasket. An elastic support member and a triggering mechanism triggered according to the height change of the water box are arranged below the water box. The triggering mechanism is used to trigger an alarm mechanism.

[0006] Preferably, the elastic support member includes a clamping member longitudinally slidably connected in the housing and an elastic sheet arranged at the bottom of the clamping member. The cross-sectional shape of the clamping member is L-shaped. The horizontal plane of the L-shape is used to support the water box. When the elastic force provided by the elastic sheet is less than the gravity of the liquid accumulated in the water box, the clamping member can slide downward.

[0007] Preferably, the triggering mechanism includes the card member and the push plate. One end of the push plate in the length direction is provided with a hook groove that is clamped with the vertical surface of the card member. When the card member slides downward, it can be unlocked from the hook groove. The outer end surface of the push plate on the side of the hook groove abuts against one end of the second spring, and the other end of the second spring abuts against the inside of the housing. Both ends of the push plate in the width direction are slidably connected to the housing, and the end of the push plate away from the second spring abuts against the alarm mechanism.

[0008] Preferably, the alarm mechanism is a siren with an airbag. The end of the push plate away from the second spring abuts against the airbag. The airbag is fixed inside the housing, and the outlet of the siren passes through the side wall of the housing and protrudes outward.

[0009] Preferably, one side of the gasket is provided with a pressing plate, and the other end of the pressing plate abuts against one end of the first spring. The end of the first spring away from the gasket abuts against the inner wall of the housing.

[0010] Preferably, one side of the housing is fixedly connected with a mounting member for fixing the housing on the bed rail.

[0011] Preferably, a rotating member is provided inside the mounting member. The rotating member is connected to a bidirectional threaded rod rotatably installed inside the mounting member. Sliders are sleeved outside both ends of the bidirectional threaded rod, and the sliders at both ends are connected by a three-section hinge plate. A fixing plate is provided at the top of the hinge plate.

[0012] Advantageous Effects

[0013] Compared with the prior art, the present utility model timely and automatically reminds medical staff when a liquid leakage problem occurs by setting a gravity-triggering mechanism and an alarm mechanism. Specifically, when the connection between the three-way pipe and the infusion pipe starts to leak, the liquid will fall onto the collection plate and gather inside the water box through the water guide groove on the collection plate. When the weight of the liquid in the water box is greater than the elastic force provided by the elastic sheet, the card member is unlocked to activate the second spring. The push plate presses the airbag under the pressure of the second spring and sounds the siren, reminding the surrounding medical staff that there is a water leakage at the connection between the three-way pipe and the infusion pipe and repair is needed.

[0014] The present utility model is provided with a bidirectional threaded rod and a fixing plate. When it is necessary to install the installation device on the bed rail, first insert the mounting member into the bed rail, then pull out the rotating member from the inside of the mounting member and rotate it. Finally, the fixing plate and the mounting member clamp the bed rail to achieve the effect of quickly installing the fixing device. Description of the Drawings

[0020] The same marks in each figure represent the same component. Specific embodiments

[0021] The following will further elaborate on the present utility model in conjunction with specific embodiments. It should be understood that these embodiments are only used to illustrate the present utility model and not to limit the scope of the present utility model. In addition, it should be understood that after reading the content taught by the present utility model, those skilled in the art can make various changes or modifications to the present utility model, and these equivalent forms also fall within the scope defined by the appended claims of this application.

[0022] The present utility model provides a medical three-way pipe fixing device for monitoring water leakage, including an outer shell 1 with an infusion pipe connection hole on its surface. A slide cover 2 is slidably connected to the upper part of the outer shell 1. A U-shaped gasket 5 for limiting the three-way pipe 6 is provided below the slide cover 2. A collection plate 7 with a plurality of water guide grooves is provided below the gasket 5. The water outlet of the water guide groove communicates with a water box 8 provided below the gasket 5. An elastic support member and a trigger mechanism triggered according to the height change of the water box 8 are provided below the water box 8. The trigger mechanism is used to trigger an alarm mechanism.

[0023] As Figure 1 shown, in a specific embodiment, the elastic support member includes a clamping part 9 longitudinally slidably connected in the outer shell 1 and an elastic sheet 10 provided at the bottom of the clamping part 9. The cross-sectional shape of the clamping part 9 is L-shaped, and the horizontal plane of the L shape is used to support the water box 8. The elastic sheet 10 provides sufficient elastic force to support the empty water box 8, and its two ends can slide in the chute at the bottom of the outer shell 1. The chute provides a deformation space for the elastic sheet 10. When the elastic force provided by the elastic sheet 10 is less than the gravity of the liquid accumulated in the water box 8, the clamping part 9 can slide downward.

[0024] The triggering mechanism includes the clamping member 9 and the push plate 11. One end in the length direction of the push plate 11 is provided with a hook groove that is clamped with the vertical surface of the clamping member 9. When the clamping member 9 slides downward, it can be unlocked from the hook groove. The outer end surface of the push plate 11 on the side of the hook groove abuts against one end of the second spring 12, and the other end of the second spring 12 abuts against the inside of the housing 1. Both ends in the width direction of the push plate 11 are slidably connected to the housing 1, and the end of the push plate 11 away from the second spring 12 abuts against the alarm mechanism.

[0025] The alarm mechanism is a siren 14 with an airbag 13. The end of the push plate 11 away from the second spring 12 abuts against the airbag 13. The airbag 13 is fixed inside the housing 1, and the outlet of the siren 14 passes through the side wall of the housing 1 and protrudes outward.

[0026] In actual use, when the connection between the tee 6 and the infusion tube starts to leak, water will fall onto the collection plate 7, and the leaked water will flow along the water guide groove on the collection plate 7 into the interior of the water box 8, thereby accumulating water inside the water box 8. As the amount of water inside the water box 8 increases, the overall weight of the water box 8 gradually rises, causing the water box 8 to start squeezing the clamping member 9, and then causing the clamping member 9 to descend along the inside of the housing 1, making the clamping member 9 start to squeeze the elastic piece 10 to contract and disengage from the inside of the push plate 11, causing the push plate 11 to lose its limit. Then, the second spring 12 can push the push plate 11 to slide along the inside of the housing 1, making the push plate 11 squeeze the airbag 13. After being squeezed, the airbag 13 will discharge gas through the siren 14, and the gas passing through the siren 14 will make a sound, reminding the surrounding medical staff that there is a leak at the connection between the tee 6 and the infusion tube and repair is needed. It should be noted that after the connection between the tee 6 and the infusion tube is repaired, the push plate 11 can be pulled to slide along the groove starting from the outer wall of the housing 1, causing the push plate 11 to pull the airbag 13 to reset and squeeze the second spring 12 to contract. When the airbag 13 resets, it will draw in gas from the outside through the siren 14 to expand. When the push plate 11 is pulled to the top of the clamping member 9, open the side plate of the housing 1, then pull out the water box 8 from the top of the clamping member 9 and pour out the water inside, so that there is no longer pressure on the top of the clamping member 9, and then the elastic piece 10 resets to push the clamping member 9 to re-insert into the inside of the push plate 11, allowing the clamping member 9 to re-limit and fix the push plate 11 through the housing 1. Then, re-insert the empty water box 8 to the top of the clamping member 9 and cover the side plate of the housing 1 to complete the reset of the structure for monitoring water leakage inside the fixing device.

[0027] One side of the gasket 5 is provided with a pressing plate 4. The other end of the pressing plate 4 abuts against one end of the first spring 3, and the end of the first spring 3 away from the gasket 5 abuts against the inner wall of the housing 1.

[0028] As needed, a mounting member 15 for fixing the housing 1 to the bed rail can be fixedly connected to one side of the housing 1. The fixed connection can be a snap connection, a bolt connection, or other common connection methods.

[0029] A rotating member 16 is provided inside the mounting member 15. The rotating member 16 is connected to a bidirectional threaded rod 17 rotatably mounted inside the mounting member 15. Sliders 18 are sleeved outside both ends of the bidirectional threaded rod 17. The sliders 18 at both ends are connected by a three-section hinge plate 19. A fixing plate 20 is provided at the top of the hinge plate 19.

[0030] Both the first spring 3 and the second spring 12 are compression springs. Internal threads matching the external threads on the surface of the bidirectional threaded rod 17 are provided inside the slider 18. The hinge plate 19 includes three flat plates hinged to each other. The two on both sides are connected to the slider 18, and the middle one is fixedly connected to the fixed block 20.

[0031] In actual use, when it is necessary to install the installation device on the bed rail, first insert the mounting member 15 into the bed rail, then pull out and rotate the rotating member 16 from the inside of the mounting member 15, so that the rotating member 16 drives the bidirectional threaded rod 17 to rotate. Further, the bidirectional threaded rod 17 drives the slider 18 to move towards the middle section of the bidirectional threaded rod 17, so that the slider 18 pushes the fixing plate 20 to fit and fix on the bed rail through the hinge plate 19, and the fixing plate 20 and the mounting member 15 clamp the bed rail, thereby fixing the fixing device on the bed rail. When it is necessary to disassemble the fixing device, just pull out and reverse the rotating member 16 from the inside of the mounting member 15, so that the rotating member 16 drives the bidirectional threaded rod 17 to reverse. Further, the bidirectional threaded rod 17 drives the slider 18 to move towards both sides of the bidirectional threaded rod 17, so that the slider 18 pulls the fixing plate 20 through the hinge plate 19 to stop fitting and fixing on the bed rail. At this time, the fixing device can be removed to achieve the effect of quickly installing and disassembling the fixing device. It should be noted that when it is necessary to install the three-way pipe 6 inside the fixing device, first pull out the sliding cover 2 from the top of the housing 1, then insert the three-way pipe 6 into the inside of the housing 1, so that the three-way pipe 6 is wrapped by the gasket 5. Further, the first spring 3 can push the gasket 5 to fit against the outer wall of the three-way pipe 6 through the pressing plate 4 to fix the three-way pipe 6. Then, the infusion pipe connected to the three-way pipe 6 is pulled out through the side groove of the housing 1, and the sliding cover 2 is reinserted into the inside of the housing 1, so that the connection part between the three-way pipe 6 and the infusion pipe is wrapped inside the housing 1 and the sliding cover 2 to prevent the connection part between the three-way pipe 6 and the infusion pipe from being hit, resulting in damage and leakage at the connection part between the three-way pipe 6 and the infusion pipe.
