Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically a chemotherapy light-proof infusion device. Background Technology

[0002] Chemotherapy is a treatment method that uses chemical drugs to inhibit the proliferation, invasion, metastasis, and spread of cancer cells, ultimately killing them. It is a very important treatment for malignant tumors, and along with surgery and radiotherapy, it is considered one of the three major methods of cancer treatment. Because some chemotherapy drugs are photosensitized and easily degrade or change their properties under light conditions, they need to be protected from light during intravenous infusion.

[0003] The existing method of light protection is to use a light-proof bag to cover the outside of the infusion bottle. However, due to the obstruction of light by the light-proof bag, it is difficult for patients to know the remaining amount of medication in the infusion bottle. Nurses may also be unable to observe the amount of medication in time due to busy nursing work, which may easily lead to backflow of blood in patients and thus affect their health. Utility Model Content

[0004] The purpose of this invention is to provide a chemotherapy light-proof infusion device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows.

[0006] A chemotherapy light-shielding infusion device includes a light-shielding bag and a weighing device. A weighing rod is located at the bottom of the weighing device. A lifting rope is connected to the upper opening of the light-shielding bag and is connected to the weighing rod. A hook is installed at the top of the weighing device. A wire is connected to the outer surface of the weighing device, and a handheld controller is installed at the end of the wire. A display screen is installed on the surface of the handheld controller. A winding mechanism is provided on the outer surface of the wire, which can wind or unwind the wire.

[0007] Therefore, by weighing the infusion bottle with a weighing device, the remaining amount of medication in the bottle can be determined simply by observing the changes in the numbers on the display screen. This allows patients to easily and promptly know the remaining amount of medication while receiving infusions in bed, thus avoiding the need for nurses to frequently check the infusion bottle, reducing their workload, and effectively reducing the risk of backflow due to untimely replacement of the infusion bottle.

[0008] With the winding mechanism, the wires can be quickly and neatly wound up when not in use. This not only reduces space usage but also effectively avoids the problem of wires getting tangled and intertwined, preventing the wires from affecting normal use in subsequent applications.

[0009] Furthermore, the winding mechanism includes a housing disposed on the outer surface of the conductor, a winding shaft rotatably connected inside the housing, a through hole opened in the middle of the winding shaft, the conductor passing through the inside of the through hole, and the conductor at both ends of the through hole being wound in opposite directions on the winding shaft, and one end of the winding shaft extending to the outside of the housing and mounted on a turntable.

[0010] Furthermore, the surface of the lifting rope has a connecting hole, and the weighing rod extends through the connecting hole to the outer surface of the lower side of the lifting rope and is fitted with a collar. The outer surface of the collar is fitted with a first bolt, and the outer surface of the weighing rod has a screw hole that matches the first bolt.

[0011] Furthermore, a second bolt is installed on the outer surface of the turntable.

[0012] Furthermore, slots are provided on both sides of the outer surface of the shell, and the slots are connected to the interior of the shell.

[0013] Furthermore, the handheld controller has a microprocessor inside, and control buttons and a speaker are respectively provided on the outer surface of the handheld controller.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows.

[0015] 1. This utility model uses a weighing device to weigh the infusion bottle. Therefore, by simply observing the changes in the numbers on the display screen, the remaining amount of medication in the infusion bottle can be determined. This allows patients to easily and promptly understand the remaining infusion volume while receiving infusions in bed, thereby avoiding the need for nurses to frequently observe the infusion bottle, reducing their workload, and effectively reducing backflow caused by untimely replacement of the infusion bottle.

[0016] 2. By setting up a winding mechanism, this utility model can quickly and neatly wind up the wires when not in use. This not only reduces the space occupied, but also effectively avoids the problem of wires getting tangled and intertwined, thus preventing the normal use of the wires from being affected by messy tangling during subsequent use.

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] In the description of the embodiments of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connection" and "installation" should be interpreted broadly. For example, "connection" can be a detachable connection or a non-detachable connection; it can be a direct connection or an indirect connection through an intermediate medium. Furthermore, "connection" can be a direct connection or an indirect connection through an intermediate medium. "Fixed" means that the relative positional relationship remains unchanged after the connection. The directional terms mentioned in the embodiments of this utility model, such as "inner," "outer," "top," and "bottom," are only for reference to the directions in the accompanying drawings. Therefore, the directional terms used are for better and clearer explanation and understanding of the embodiments of this utility model, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the embodiments of this utility model.

[0024] In this embodiment of the invention, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined with "first" and "second" may explicitly or implicitly include one or more of that feature.

[0025] like Figure 1-4As shown, a chemotherapy light-shielding infusion device includes a light-shielding bag 100 and a weighing device 102. A weighing rod 106 is provided at the bottom of the weighing device 102. A lifting rope 101 is connected to the upper opening of the light-shielding bag 100 and is connected to the weighing rod 106. A hook 107 is installed at the top of the weighing device 102. A wire 103 is connected to the outer surface of the weighing device 102. A handheld controller 104 is installed at the end of the wire 103, and a display screen 105 is provided on the surface of the handheld controller 104. A winding mechanism 200 is provided on the outer surface of the wire 103, which can wind or unwind the wire 103.

[0026] In use, the nurse places the IV bottle into the light-shielding bag 100 for infusion, hangs the hook 107 on the IV stand, and weighs the IV bottle using the weighing device 102. Before infusion, the weight of the empty IV bottle and the light-shielding bag 100 is measured first. The total weight measured by the weighing device 102 is subtracted from the weight of the empty bottle and the light-shielding bag 100 to obtain the approximate weight of the remaining medication (the IV tubing is not included because it is lightweight and partially rests on the bed). Then, the handheld controller 104 is placed on the bed, and the weight measured by the weighing device 102 is displayed on the display screen 105. Therefore, the patient can observe the display screen 105 at any time to understand the remaining medication volume and promptly notify the nurse to replace the IV bottle. This avoids the need for the nurse to frequently observe the IV bottle, reduces the nurse's workload, and effectively reduces the risk of backflow due to untimely IV bottle replacement.

[0027] When not in use, the wire 103 can be wound up by the winding mechanism 200, which not only reduces the space occupied, but also effectively avoids the problem of the wires 103 tangling and crossing each other, and avoids the situation where the wires 103 are messy and tangled and affect their normal use in subsequent use.

[0028] Preferably, the winding mechanism 200 includes a housing 201 disposed on the outer surface of the conductor 103, a winding shaft 202 rotatably connected inside the housing 201, a through hole 203 opened at the middle position of the winding shaft 202, and the conductor 103 passes through the interior of the through hole 203. The two ends of the conductor 103 located at the through hole 203 are respectively wound in opposite directions on the winding shaft 202. One end of the winding shaft 202 extends to the outside of the housing 201 and is equipped with a turntable 204.

[0029] Since the portions of the wire 103 located at both ends of the through hole 203 are wound in opposite directions on the take-up shaft 202, the turntable 204 drives the take-up shaft 202 to rotate in both directions, which can achieve the purpose of simultaneously winding or unwinding the portions of the wire 103. This allows for adjustment of the length of the wire 103 and winding it up when not in use.

[0030] Preferably, the surface of the lifting rope 101 is provided with a connecting hole 300, the weighing rod 106 extends through the connecting hole 300 to the outer surface of the lower side of the lifting rope 101 and is fitted with a collar 301, the outer surface of the collar 301 is fitted with a first bolt 302, and the outer surface of the weighing rod 106 is provided with a screw hole 303 that matches the first bolt 302.

[0031] When the light-shielding bag 100 is damaged, the first bolt 302 can be unscrewed from the screw hole 303, and then the weighing rod 106 can be pulled out from the connecting hole 300 to separate the weighing device 102 from the light-shielding bag 100. When installing a new light-shielding bag 100, simply pass the weighing rod 106 through the connecting hole 300, put the collar 301 on the outer surface of the weighing rod 106 from the bottom, and finally screw the first bolt 302 into the screw hole 303.

[0032] Preferably, a second bolt 400 is mounted on the outer surface of the turntable 204.

[0033] By tightening the second bolt 400, its end is pressed against the outer surface of the housing 201, thereby fixing the winding shaft 202 and preventing it from rotating arbitrarily, which could cause the wire 103 to loosen.

[0034] Preferably, slots 500 are provided on both sides of the outer surface of the housing 201, and the slots 500 are connected to the interior of the housing 201.

[0035] The slot 500 ensures that the wire 103 will not be obstructed when it moves laterally during winding or unwinding.

[0036] Preferably, the handheld controller 104 has a microprocessor inside, and a control button 600 and a speaker 601 are respectively provided on the outer surface of the handheld controller 104.

[0037] An alarm value can be preset via control button 600. When the value displayed on display 105 is lower than the alarm value, the microprocessor will trigger speaker 601 to emit an alarm signal to remind the patient, thus preventing the patient from falling asleep or being distracted by other things and failing to pay attention to the remaining amount of medication, thereby further improving the safety of infusion.

[0038] The above is a detailed description of the present invention in conjunction with specific embodiments, and it should not be construed that the specific implementation of the present invention is limited to these descriptions. For those skilled in the art, any equivalent substitutions or obvious modifications made without departing from the concept of the present invention, and which have the same performance or use, should be considered as falling within the patent protection scope defined by the submitted claims.
