Description

Technical Field

[0001] This utility model relates to the field of medical auxiliary equipment, and in particular to a multifunctional infusion tool. Background Technology

[0002] Intravenous infusion is a commonly used clinical treatment method, characterized by large dosage and direct entry into the bloodstream.

[0003] During the medication preparation process, a wide variety of drugs are involved, requiring the opening and dispensing of multiple different types of medications. This presents the following problems: 1. For ampoules, the first step is to use a grinding wheel to scratch the surface, then pry it open by hand or with a metal instrument. This can easily cut fingers or allow broken glass to fall into the ampoule, contaminating the medication. 2. Aluminum-plastic combination caps are often pried open by hand, which can easily injure the index finger or thumb, greatly consuming the strength of medical staff and causing significant local pain in the fingers due to repeated pressure. 3. For pull-tab designs on glucose and saline solution bottles, it is particularly difficult to open with fingers, easily leading to finger pain.

[0004] The following problems exist during intravenous infusion: 1. When air needs to be released from the infusion bottle by hanging it upside down, the index finger must be used to pry out the pull ring at the bottom of the bottle before hanging it upside down on the infusion stand. This can easily injure the index fingernail and nail groove. 2. When the infusion is completely emptied, the air in the tubing below the Murphy drip tube must be purged before changing the infusion bottle. There is no special infusion air release tool available. Nurses often use the method of wrapping the tubing around a pen to release air, which requires the patient to raise their hand, affecting the nurse's work efficiency and causing inconvenience to the patient. 3. When it is necessary to change the extension tubing of the micro-infusion pump, the connection between the T-connector and the extension tubing is often too tight, and the end of the extension tubing is flat and small, making it difficult to unscrew by hand. Currently, hemostatic forceps are often used to assist in unscrewing, but cleaning and disinfecting the hemostatic forceps is costly.

[0005] Several tools exist in the prior art for facilitating the opening of medication bottles during preparation. For example, utility model patent application number CN201920126704.1 discloses a multifunctional infusion preparation auxiliary tool, including a main body with an ampoule opening hole, a grinding wheel, a cap opening groove, cap opening teeth, and a movable part. The ampoule opening hole consists of several circular through holes of different diameters. The grinding wheel is fixed to the lower edge of the main body with screws. The cap opening groove is located on the lower side of the main body and is trapezoidal in shape. The cap opening teeth are located inside the cap opening groove. The movable part includes a movable rod, a hook, a spike, and a collar. The hook, spike, and collar are arranged side by side at a 30° angle at the head of the movable rod. The other end of the movable rod is connected to a push handle, which is located in a sliding groove. This utility model can be used to assist in opening the caps of various medications, such as ampoules, vials, and infusion bag sealing valves. It can assist medical personnel in the entire process of infusion preparation, saving time and effort and reducing the risk of injury.

[0006] However, in the existing technology, there is no tool for purging air from the infusion tubing, and there are few tools specifically designed to unscrew the connection between the infusion extension tube and the T-connector. Therefore, there is an urgent need for an infusion tool that is easy to use and versatile, which is convenient for opening various bottle caps when preparing medicines, and also convenient for purging air and unscrewing the connection between the infusion extension tube and the T-connector during the infusion process.

[0033] The following detailed description, in conjunction with the accompanying drawings, will further illustrate this utility model. Detailed Implementation

[0034] Please see Figures 1-4 In a preferred embodiment of this utility model, a multifunctional infusion tool includes a body 1. The body 1 is provided with an ampoule opening hole 11 and a grinding wheel 12. After cutting the ampoule with the grinding wheel 12, it is broken off with the ampoule opening hole 11. Preferably, in this embodiment, the grinding wheel 12 is mounted on the body 1 through a grinding wheel 12 mounting hole. The ampoule opening hole 11 and the grinding wheel 12 mounting hole are tangent to each other. The ampoule opening hole 11 and the grinding wheel 12 mounting hole are connected by a connecting port 121, which includes a tangent point where the two holes are tangent. In use, the ampoule is placed over the head using the ampoule opening hole 11, with the neck of the ampoule located at the connecting port 121. The neck of the ampoule is cut using the grinding wheel 12 at the connecting port 121, and then the neck can be easily separated by gently prying it open with the help of the ampoule opening hole 11. Clinical trials have shown that using this invention to break the neck of the ampoule takes less time than breaking it by hand, thus improving work efficiency. In addition, the connection between the ampoule opening hole 11 and the grinding wheel 12 mounting hole in this invention allows for direct breaking of the ampoule neck after cutting, eliminating the need for cutting elsewhere before breaking it open with the ampoule opening hole 11, making it simpler and more convenient, and further improving medication dispensing efficiency.

[0035] Furthermore, the main body 1 is also provided with a flared opening 131 and an exhaust slit 132. The larger opening end of the flared opening 131 is located on the end face of the main body 1, and the smaller opening end is connected to the exhaust slit 132, which has a strip-shaped structure. In use, the infusion tube 2 is inserted into the exhaust slit 132 through the flared opening 131. By moving the main body 1, the exhaust slit 132 slides relative to the infusion tube, thereby venting the air in the infusion tube 2. This allows for simple and efficient venting of the infusion tube 2. (See reference for details.) Figure 2 Experiments show that using this invention for venting does not damage the infusion set, and compared to existing methods of venting by winding, the venting time using this invention is shorter.

[0036] Furthermore, the main body 1 has a notch 141 for inserting the head 3 of the infusion extension tube and a slot 142 for inserting the protrusion of the head 3 of the infusion extension tube. The notch 141 is semi-circular and is located on the end face of the main body 1. The slot 142 connects to the notch 141, with the connection point being the middle position of the semi-circular structure of the notch 141. In use, the head of the infusion extension tube is inserted into the notch 141, and the protrusion on the head 3 of the infusion extension tube is inserted into the slot 142. By rotating the main body 1, the connection between the infusion extension tube and the tee 4 can be loosened, facilitating the replacement of the infusion extension tube. (See reference for details.) Figure 3 Preferably, the present invention also includes a pull rod 151, which is spaced apart from the body 1. One end of the pull rod 151 is connected to the body 1 via a connecting part 152, and the other end is a free end. When it is necessary to open the pull ring on the medicine bottle, the pull ring can be slipped onto the pull rod 151 from the free end, and then force can be applied to open the pull ring. In addition, the free end can also be used to pry out the pull ring at the bottom of the infusion bottle when it is necessary to hang the infusion bottle upside down to release air. Experiments were conducted on opening the pull ring by hand, prying open the pull ring with scissors, and opening the pull ring using the present invention. After the experiments, nurses were interviewed about their experience and willingness to use the invention. They all felt that opening the pull ring by hand was the most flexible and quick, but it was easy to injure the index finger joint and nail. Using scissors and other tools was cumbersome and awkward. Using the present invention was more convenient and flexible. Considering occupational exposure and other related factors, they preferred to use the present invention to pry open the infusion bottle mouth and pry out the bottom ring of the infusion bottle. Additionally, the T-connector 4 can be secured using the gap between the pull rod 151 and the body 1. Rotation loosens the connector of the T-connector 4, facilitating the replacement of the infusion extension tubing. More preferably, the pull rod 151 is not on the same side as the bayonet 141 and the flared end 131, preventing the pull rod 151 from obstructing their use and making the entire tool more convenient to use. In this embodiment, the body 1, pull rod 151, and connecting part 152 are integrally molded, resulting in a neat appearance suitable for mass production using molds. Furthermore, the body 1 and the pull hook are made of stainless steel, a readily available material with sufficient strength and durability.

[0037] Preferably, the distance between the pull rod 151 and the body 1 is less than the diameter of the bottle cap. The end of the body 1 facing the pull rod 151 has a prying part 16 for opening the aluminum-plastic composite cap 5. In use, a portion of the aluminum-plastic composite cap 5 is placed above this end of the body 1, with the other portion below the pull rod 151. Applying force to lift the body 1 upwards opens the aluminum-plastic composite cap 5. This is more convenient, faster, and less strenuous than opening it by hand, and does not cause pain to the user. More preferably, the prying part 16 is an inclined surface on the end face of the body 1. Placing the aluminum-plastic composite cap 5 on this inclined surface during use prevents it from sliding off the body 1. (See reference...) Figure 4 .

[0038] Preferably, a scale 17 is provided on one side of the main body 1. This side is not on the same side as the pull rod 151, the bayonet 141, and the flared mouth 131. The scale 17 is located at the edge of this side for easy measurement. Additionally, in this embodiment, the main body 1 is provided with several contrast rings 18 for comparing pupil size, each with a different diameter. The size of the patient's pupil can be observed and compared through the contrast rings 18.
