Description

Technical Field

[0001] The invention relates to the technical field of medical devices, in particular to an infusion light shield for chemical treatment. Background Art

[0002] Chemotherapy is one of the commonly used methods for treating cancer in clinical practice. During the infusion of chemotherapy drugs, many chemotherapy drugs are sensitive to light and easily decompose under light. Currently, a light shield and a light-shielding infusion set are generally used in combination. Both the light shield and the light-shielding infusion set are dark brown and translucent in design, which can effectively block light and reduce the contact between drugs and light, thereby maintaining the stability of the drugs.

[0003] The dark brown translucent design of the light shield will reduce the light transmittance, making it very difficult to observe the liquid level in the infusion bottle from the outside. Medical staff and accompanying personnel cannot directly see the height and drop of the liquid like using a transparent container, and can only roughly estimate the progress of the infusion by blurred outlines and slight changes in light and shadow. This makes it difficult for medical staff and accompanying personnel to intuitively observe the progress of the infusion and the remaining amount of the drug. In a busy ward, medical staff may not be able to discover in time that the infusion is about to end, thereby delaying the opportunity to replace the infusion bottle or remove the needle. When the liquid in the infusion bottle is infused, due to the effect of venous pressure, blood may flow back into the infusion tube. If a large amount of blood is returned, the blood may coagulate in the infusion tube to form a thrombus, which may easily lead to safety hazards.

[0004] For this reason, a light shield for infusion used in chemotherapy is proposed. Summary of the invention

[0008] Furthermore, two ends of spring one are fixedly connected to the inner box and the equipment box respectively, and one side of the equipment box is set as a dark brown transparent acrylic observation surface.

[0009] Furthermore, the cross plate passes through the long slot.

[0010] Furthermore, the folding cloth is foldable, and the folding cloth is made of opaque cloth material.

[0011] Furthermore, the material of the scale plate is set to iron, and the side of the buzzer close to the scale plate is set to a magnet surface.

[0012] Furthermore, a push switch is provided on the bottom surface of the buzzer, and the push switch is located on the moving path of the horizontal plate.

[0013] Furthermore, the pressure plate is limitedly and slidably connected to the side groove, the two ends of the two springs are respectively fixedly connected to the fixed clamping block and the movable clamping block, and the cross bar is located on the moving path of the vertical bar.

[0014] Furthermore, the two angle grooves are parallel at the top and far away from each other at the bottom. The rack and the gear can engage with each other after contacting.

[0015] Furthermore, one side where the fixed clamp block and the movable clamp block are close to each other is set as a rubber arc surface, and the inside of the box door is set as a dark brown transparent acrylic observation surface.

[0016] Compared with the prior art, the present invention has the following beneficial effects: Through the movement of the horizontal plate on the scale plate and the distance between the horizontal plate and the buzzer, medical staff and accompanying personnel can visually observe the progress of infusion and the remaining amount of medicine. Medical staff do not need to frequently try to observe the progress of infusion through the dark brown translucent light-shielding cover, thereby saving a lot of time and energy. It can also avoid the safety hazard of blood flowing back into the infusion tube and coagulating to form thrombus under the action of venous pressure after the liquid in the infusion bottle is infused. In addition, since the solution in the infusion bottle is output at a uniform speed and volume, the movement of the horizontal plate is also uniform. Medical staff and accompanying personnel can timely discover abnormal conditions during the infusion process by observing the movement of the horizontal plate to avoid the infusion speed being too fast or too slow. This helps to adjust the infusion speed in time to ensure that the drug solution is infused into the patient's body at an appropriate speed to avoid adverse reactions caused by infusion speed problems. The buzzer alarm can let medical staff know in time that the infusion is about to end. Medical staff can prepare the next bottle of infusion medicine or remove the needle in advance to ensure the continuity of the infusion process. This helps to optimize the entire nursing workflow, reduce the confusion caused by untimely infusion connection, improve the work efficiency and quality of medical staff, and prevent the situation where the infusion is over but the medical staff is not aware of it, which can ensure the medical safety of the patient; The infusion bottle is clamped and fixed by two air bags. When the liquid in the infusion bottle is gradually reduced, its center of gravity will change and it is easily affected by the external environment. For example, when a person touches the equipment box or a patient moves and pulls the light-shielded infusion tube, it will shake. At this time, the resistance of the infusion bottle can effectively reduce this shaking and ensure the stability of the infusion process. The elastic design of the air bag can adapt to infusion bottles or infusion bags of different shapes and sizes to provide stable support. The light-proof infusion tube is wrapped and limited by the two rubber arc surfaces of the fixed clamp block and the movable clamp block, which can effectively ensure the stability of the connection between the light-proof infusion tube and the infusion bottle during the infusion process. At this time, the light-proof infusion tube can no longer be drawn out from the inside of the infusion bottle, and the movement of the light-proof infusion tube can be physically restricted. In the actual hospital environment, the patient may inadvertently pull the light-proof infusion tube, or the medical staff may touch the light-proof infusion tube during the operation. The fixing effect of the fixed clamp block and the movable clamp block can prevent such accidental pulling from being transmitted to the interface between the light-proof infusion tube and the infusion bottle, thereby preventing the light-proof infusion tube from detaching from the infusion bottle, ensuring the continuity and safety of the infusion process. Since the infusion bottle and the light-proof infusion tube are no longer limited and the inner box is at the lowest end, the top operating space of the inner box inside the equipment box is maximized, which makes it convenient for medical staff to replace the infusion bottle inside the inner box, allowing medical staff to replace the infusion bottle more quickly and conveniently, reducing the operation steps and time.

[0019] 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 described embodiments 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 creative work are within the scope of protection of the present invention.

[0020] Embodiments provided by the present invention: Embodiments of the present invention

[0021] See also Figures 1 to 4As shown, a light-shielding device for infusion for chemotherapy comprises an infusion bottle 11 and a light-shielding infusion tube 12. The light-shielding infusion tube 12 is plugged into the bottom end of the infusion bottle 11. The outside of the infusion bottle 11 is provided with a residual display alarm component for real-time display of the residual content inside the infusion bottle 11 when the infusion bottle 11 is in use. The residual display alarm component comprises an equipment box 21. The equipment box 21 is arranged on the outside of the infusion bottle 11. The inside of the equipment box 21 is slidably connected with an inner box 22. The infusion bottle 11 is arranged inside the inner box 22. The light-shielding infusion tube 12 passes through the inner box 22 and the equipment box 21 and extends to the outside. The light-shielding infusion tube 12 is movably connected to the inner box 22 and the equipment box 21. The inner box 22 is fixed to the top surface of the inner wall of the equipment box 21. It is connected with a multi-section telescopic rod 23, and a spring 24 is arranged inside the multi-section telescopic rod 23. The two ends of the spring 24 are fixedly connected to the inner box 22 and the equipment box 21 respectively. One side of the equipment box 21 is arranged with a dark brown transparent acrylic observation surface, which is used to facilitate medical staff and accompanying personnel to observe the inside of the equipment box 21. A long groove 25 is provided on the side of the equipment box 21 away from the observation surface. A cross plate 26 is fixedly connected to the side of the top of the inner box 22 close to the long groove 25. The cross plate 26 passes through the long groove 25. Two folding cloths 27 are symmetrically fixedly connected between the upper and lower surfaces of the cross plate 26 and the long groove 25. A scale plate 28 is fixedly connected to the outer wall of the equipment box 21 close to the long groove 25, and a buzzer 29 is slidably connected to the surface of the scale plate 28.

[0022] Among them: the folding cloth 27 is foldable, and the folding cloth 27 is set to an opaque cloth material, so as to ensure the free sliding of the horizontal plate 26 on the long groove 25. When the horizontal plate 26 slides on the long groove 25, the long groove 25 on the same side as the sliding direction will be folded, and the long groove 25 in the opposite direction will be extended, which can ensure that external light will not enter the interior of the equipment box 21 from the long groove 25.

[0023] Among them: the material of the scale plate 28 is set to iron, and the side of the buzzer 29 close to the scale plate 28 is set to a magnetic surface, so that the medical staff can freely adjust the position of the buzzer 29 on the scale plate 28, and when the medical staff does not pull the buzzer 29, the scale plate 28 can be magnetically attracted to the buzzer 29, so that the position of the buzzer 29 is fixed, and a push switch is set on the bottom surface of the buzzer 29, and the push switch is located on the moving path of the horizontal plate 26. When the push switch is resisted by the horizontal plate 26, the buzzer 29 is powered on and an alarm sound is issued.

[0024] Among them: the infusion bottle 11 and the light-proof infusion tube 12 are both existing known structures. It should be noted that the accompanying drawings only show a part of the light-proof infusion tube 12 connected to the infusion bottle 11, and the entire light-proof infusion tube 12 is not shown. The inner box 22 is set to a transparent acrylic material.

[0025] Among them: due to the multi-section structure of the multi-section telescopic rod 23, when the spring 24 is fully contracted, the top surface of the inner box 22 will be flush with the lower surface of the top fixed end of the multi-section telescopic rod 23, and it can be concluded that when the inner box 22 is flush with the lower surface of the fixed end of the multi-section telescopic rod 23, the solution inside the infusion bottle 11 is consumed or there is little left.

[0026] When the remaining amount display alarm component is used: in the initial state, the infusion bottle 11 is located inside the inner box 22, the light-proof infusion tube 12 passes through the equipment box 21 and the inner box 22, and the infusion bottle 11 is full of solution. Therefore, the gravity of the infusion bottle 11 will press the inner box 22 downward and stretch the spring 1 24. Then the medical staff adjusts the buzzer 29 to a position on the scale plate 28 that is slightly lower than the lower surface of the fixed end of the multi-section telescopic rod 23. At this time, the medical staff moves the light-proof infusion tube 12 away from the end of the infusion bottle 11 to perform infusion treatment on the patient. As the liquid medicine in the infusion bottle 11 is injected into the patient's body, At this time, as the solution in the infusion bottle 11 is discharged, the overall weight of the infusion bottle 11 is reduced, which will cause the spring 1 24 to gradually elastically contract. The elastic contraction of the spring 1 24 drives the inner box 22 to slide upward inside the equipment box 21. At this time, the cross plate 26 synchronously slides upward inside the long groove 25. When the cross plate 26 moves to fit the bottom of the buzzer 29, the solution in the infusion bottle 11 is about to be consumed, and the push switch will be squeezed. At this time, the buzzer 29 is powered on and an alarm sound is sounded. When the medical staff hear the alarm and come to the patient's vicinity, they can The capacity of the infusion bottle 11 can be observed through the dark brown transparent acrylic observation surface. As the solution inside the infusion bottle 11 is about to be exhausted, the medical staff can prepare for the infusion of the next bottle of solution or perform the medical operation of removing the needle. Through the movement of the horizontal plate 26 on the scale plate 28 and the distance between the horizontal plate 26 and the buzzer 29, the medical staff and the accompanying personnel can visually observe the progress of the infusion and the remaining amount of the medicine. The medical staff does not need to frequently try to observe the progress of the infusion through the dark brown translucent light shield, thereby saving a lot of time and energy, and also avoiding the infusion of the liquid in the infusion bottle 11. Afterwards, due to the failure to remove the needle or replace the next infusion bottle 11 in time, under the action of venous pressure, blood flows back into the infusion tube and coagulates to form a thrombus, which may cause a safety hazard. In addition, since the solution inside the infusion bottle 11 is output at a uniform speed and volume, the movement of the cross plate 26 is also uniform. Medical staff and accompanying personnel can observe the movement of the cross plate 26 to promptly discover abnormal conditions during the infusion process and avoid the infusion speed being too fast or too slow. This helps to adjust the infusion speed in time to ensure that the drug solution is injected into the patient's body at an appropriate speed and avoid adverse reactions caused by infusion speed problems.

[0027] And through the alarm sound of the buzzer 29, the medical staff can find out in time that the infusion is about to end. The medical staff can prepare the next bottle of infusion medicine or remove the needle in advance to ensure the continuity of the infusion process. This helps to optimize the entire nursing workflow, reduce the confusion caused by untimely infusion connection, improve the work efficiency and quality of medical staff, and at the same time prevent the situation where the infusion is ended but the medical staff is not aware of it, thereby ensuring the medical safety of the patient.

[0028] Example 2: Please refer to Figures 4 to 8 As shown, it also includes a stable replacement component arranged on the equipment box 21, which is used to ensure the stability of the infusion bottle 11 during the infusion process and to facilitate medical staff to replace the infusion bottle 11. The stable replacement component includes two angle grooves 31, and the two angle grooves 31 are symmetrically opened on the inner wall of the equipment box 21 with the multi-section telescopic rod 23 as the axis. An L-shaped rod 32 is slidingly connected to each of the two angle grooves 31. The ends of the two L-shaped rods 32 away from the angle grooves 31 are slidingly connected to the inner box 22, and the ends of the two L-shaped rods 32 located inside the inner box 22 are each fixedly connected with an air bag 33, the outer wall of the equipment box 21 is slidingly connected to a box door 34, and the top surface of the box door 34 is fixedly connected to a rack 35, and a threaded rod 36 is rotatably connected to the equipment box 21, and a gear 37 is fixedly connected to the top of the threaded rod 36. There is a pressure plate 38, and a side groove 39 is opened on the inner wall of the equipment box 21 near the pressure plate 38. The pressure plate 38 and the side groove 39 are limitedly slidably connected. The bottom surface of the outer wall of the equipment box 21 is fixedly connected to the bottom box 310, and the bottom surface of the outer wall of the bottom box 310 is fixedly connected to the fixed clamping block 311. Two guide rods 312 are symmetrically fixedly connected to the fixed clamping block 311. The surfaces of the two guide rods 312 are slidably connected to a movable clamping block 313. The surfaces of the two guide rods 312 are respectively sleeved with a spring 2 314. The two ends of the two springs 2 314 are fixedly connected to the fixed clamping block 311 and the movable clamping block 313 respectively. A cross bar 315 is fixedly connected to the side of the movable clamping block 313 away from the fixed clamping block 311. The bottom surface of the box door 34 is fixedly connected to a vertical rod 316, and the cross bar 315 is located on the moving path of the vertical rod 316.

[0029] Among them: Figure 6 As shown, the two angle grooves 31 are composed of two vertical grooves and two arc grooves, so that the two L-shaped rods 32 slide to the arc grooves to separate from each other, and slide to the vertical grooves to approach each other.

[0030] Wherein: the rack 35 and the gear 37 mesh with each other.

[0031] The transverse plate 26 is located on the moving path of the pressing plate 38 , and the transverse plate 26 and the pressing plate 38 are pressed and matched.

[0032] Among them: a cavity is set at the top of the bottom box 310, and the light-proof infusion tube 12 passes through the bottom of the bottom box 310. When in use, the medical staff inserts the light-proof infusion tube 12 from the bottom of the bottom box 310 upward to a certain length, so that a certain amount of the light-proof infusion tube 12 is retained inside the bottom box 310. The function is to ensure that when the infusion bottle 11 is lifted along with the inner box 22, the connection between the infusion bottle 11 and the light-proof infusion tube 12 will not be disconnected.

[0033] Among them: the side where the fixed clamp block 311 and the movable clamp block 313 are close to each other is set as a rubber arc surface. It should be noted that when the fixed clamp block 311 and the movable clamp block 313 conflict with each other, the two rubber arc surfaces of the fixed clamp block 311 and the movable clamp block 313 will wrap the light-proof infusion tube 12, but will not apply pressure to the light-proof infusion tube 12. The light-proof infusion tube 12 is limited only by the friction force of the rubber.

[0034] Wherein: the interior of the box door 34 is set as a dark brown transparent acrylic observation surface.

[0035] The stable replacement assembly has two use stages. The first use stage is when the rack 35 seals the inside of the equipment box 21 and the infusion bottle 11 is fully loaded with liquid medicine for infusion work, specifically as follows: The two L-shaped rods 32 are lifted synchronously with the inner box 22, so that the two L-shaped rods 32 slide upward synchronously inside the angle groove 31 on the same side, and then the two L-shaped rods 32 gradually gather together, so that the ends of the two L-shaped rods 32 located inside the inner box 22 gather together to push the two air bags 33, and then the two air bags 33 approach each other and contact the side wall of the infusion bottle 11 during the movement. At this time, the two air bags 33 clamp the infusion bottle 11 and fix it. When the liquid medicine in the infusion bottle 11 gradually decreases, its center of gravity will change and it will be easily affected by the external environment. For example, when a person touches the equipment box 21 or a patient moves and pulls the light-proof infusion tube 12, the infusion bottle 11 will shake. At this time, the resistance of the infusion bottle 11 can effectively reduce this shaking, ensure the stability of the infusion process, and the infusion bottle 11 will not be affected by the external environment. Moreover, the elastic design of the air bags 33 can adapt to infusion bottles 11 or infusion bags of different shapes and sizes to provide stable support.

[0036] At this time, the cross bar 315 does not conflict with the vertical bar 316, the movable clamp block 313 does not move, the spring 2 314 does not undergo elastic deformation, the movable clamp block 313 conflicts with the fixed clamp block 311, and the two rubber arc surfaces of the fixed clamp block 311 and the movable clamp block 313 wrap the light-proof infusion tube 12 and limit the light-proof infusion tube 12, which can effectively ensure the stability of the connection between the light-proof infusion tube 12 and the infusion bottle 11 during the infusion process. At this time, the light-proof infusion tube 12 can no longer be removed from the infusion bottle 11. 1 is drawn out, which can physically restrict the movement of the light-shielding infusion tube 12. In the actual hospital environment, the patient may accidentally pull the light-shielding infusion tube 12, or the medical staff may touch the light-shielding infusion tube 12 during the operation. The fixing effect of the fixed clamp block 311 and the movable clamp block 313 can prevent such accidental pulling from being transmitted to the interface between the light-shielding infusion tube 12 and the infusion bottle 11, thereby preventing the light-shielding infusion tube 12 from being separated from the infusion bottle 11, thereby ensuring the continuity and safety of the infusion process.

[0037] The second use stage of the stable replacement assembly is: when the liquid medicine in the infusion bottle 11 is exhausted, the top of the inner box 22 is flush with the lower surface of the fixed end of the multi-section telescopic rod 23, and the pressing plate 38 is at the top of the threaded rod 36, when the medical staff needs to replace the infusion bottle 11, the details are as follows: The gear 37 is then rotated so that the inner box 22 can move downwardly and the spring 24 is stretched so that the two air bags 33 are gradually moved away from each other to release the clamping limit of the infusion bottle 11. In the process of moving the box door 34, the box door 34 will also drive the vertical rod 316 to move synchronously. When the bottle 31 is in the closed position, the spring 314 is in a state of being pulled out of the closed position, and the spring 314 is in a state of being pulled out of the closed position, so that the bottle 31 is in a state of being pulled out of the closed position, and the bottle 31 is in a state of being pulled out of the closed position, so that the bottle 31 is in a state of being pulled out of the closed position, and the bottle 31 is in a state of being pulled out of the closed position, and the bottle 31 is in a state of being pulled out of the closed position, so that the bottle 31 is in a state of being pulled out of the closed position, and the bottle 31 is in a state of being pulled out of the closed position, and the bottle 31 is in a state of being pulled out of the closed position, However, it should be noted that when the box door 34 is fully closed, the rack 35 and the gear 37 are in a separated state, and the two are not in contact and meshing. Therefore, during normal infusion, when the cross plate 26 drives the threaded rod 36 and the gear 37 to rotate, the rack 35 will not get stuck in the gear 37 or the box door 34 will not be driven in the opposite direction by the gear 37.

[0038] After completion, the medical staff places the new infusion bottle 11 inside the inner box 22, and then inserts a certain amount of the light-proof infusion tube 12 into the cavity of the bottom box 310, and then slides the box door 34 in the opposite direction. At this time, the pressure plate 38 moves to the top of the threaded rod 36, and the threaded rod 36 no longer conflicts with the cross plate 26. The fixed clamp block 311 conflicts with the movable clamp block 313, clamping the light-proof infusion tube 12 to a limit position. At this time, the stable replacement component is reset.
