Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of medical equipment, in particular to an intravenous injection device. Background Art
[0002] Intravenous injection is a medical method, that is, blood, liquid medicine, nutrient solution and other liquid substances are directly injected into the vein. Intravenous injection can be divided into transient and continuous. Transient intravenous injection is mostly injected directly into the vein with a syringe, which is the common "injection"; continuous intravenous injection is implemented by intravenous drip, commonly known as "drip". When in use, in order to avoid the problem of the infusion tube falling off due to personnel misoperation and equipment displacement, the infusion tube and the needle handle are often required to be fixed at the injection site. At present, the needle and the infusion tube are generally fixed by bending the infusion tube (usually twice) and then using tape or fixing dressing to stick to the back of the hand. However, due to the curved shape of the infusion tube under this fixing method, it is necessary to stick tape multiple times to maintain the position and shape of the infusion tube. If the fixation is not appropriate, the infusion line is prone to twisting, folding or excessive pressure, which affects the infusion effect. Utility Model Content
[0003] Therefore, in order to overcome the above problems, the utility model provides an intravenous injection device including a retractor capable of retracting the infusion tube and facilitating the fixation of the infusion tube.

[0005] At least one reel includes a measuring tape and a reel connected to the measuring tape, a reeling cavity is formed between the measuring tape and the reeling tape, and the infusion tube is passed through the reeling cavity; the reel has a first state in which the measuring tape is in the shape of a ruler, and a second state in which the reel is in the shape of a measuring tape when an external force is applied to the measuring tape and the infusion tube is reeled in the shape of a measuring tape.
[0006] In an optional embodiment, the winding belt is a bag-shaped belt with an opening at one end; the intravenous injection device also includes a warm liquid layer, and when the warm liquid layer generates heat during operation, it is arranged in the winding belt through the opening.
[0007] In an optional embodiment, the average heating temperature of the warm liquid layer is between 35°C and 45°C.
[0008] In an optional embodiment, the winding belt is an elastic belt, and when the winding belt is stretched, it is suitable for the infusion needle to pass through the winding cavity.

Therefore, the present invention is not limited to a specific embodiment, but extends to various modifications that still fall within the scope of the appended claims.
[0025] Furthermore, in order to provide a concise description of the exemplary embodiments, not all features of the actual embodiments (i.e., those features that are not relevant to the currently considered best mode for carrying out the present invention, or those features that are not relevant to the implementation of the present invention) may be described. Moreover, the technical features involved in the different embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.
[0026] Please refer to Figure 1 and Figure 2 , is a structural schematic diagram of an intravenous injection device provided by an embodiment of the utility model, the intravenous injection device comprises an infusion tube 1, an infusion needle 2 and at least one reel 3; wherein the infusion needle 2 is fixed to the end of the infusion tube 1; the reel 3 comprises a reel measure 31 and a reel belt 32 connected to the reel measure 31, a reeling cavity is formed between the reel measure 31 and the reel belt 32, and the infusion tube 1 is inserted into the reeling cavity; the reel 3 has a first state in which the reel measure 31 is in the shape of a ruler, and a second state in which the reel measure 31 is in the shape of a tape measure after an external force is applied to the reel measure 31 to reel in the infusion tube 1.
[0027] Specifically, the width of the tape measure 31 is slightly larger than the diameter of the infusion tube 1, and the length of the tape measure 31 (that is, the length of the reel 3) can be set according to the reeling needs in the actual application scenario. In specific implementation, the length of the tape measure 31 can be set between 10cm and 18cm; in specific implementation, when the distance between the hanging position of the infusion bottle and the patient's hand is close and the hanging length of the infusion tube 1 is long, two or more reels 3 can be set to better tighten the infusion tube 1.
[0028] Specifically, relative to the infusion tube 1, the reel 3 does not need to be a strictly disposable item. Therefore, in actual application, in order to reduce the application cost of the intravenous injection device in this embodiment, the reel 32 in the reel 3 can be set as an elastic belt, so that when the reel 32 is stretched, the diameter of the reeling cavity between the reel 32 and the reeling tape 31 increases, and the infusion needle 2 can freely pass through the reeling cavity with the increased diameter; at this time, when an infusion tube 1 is used up, the reel 3 mounted on it can be removed from the infusion needle 2, and the removed reel 3 can be mounted on the outside of another infusion tube 1 for continued use.
[0029] In specific implementation, the structure of the infusion needle 2 in this embodiment can be any existing one. Figure 1 and Figure 2 As shown, the infusion needle 2 includes a needle body 21 and a needle handle 22, wherein the needle body 21 is fixedly connected to the infusion tube 1, and the needle handle 22 is fixed to the outer periphery of the needle body 21 and is located at one end of the needle body 21 close to the infusion tube 1. In a specific implementation, the needle handle 22 in the infusion needle 2 can be Figure 2 When there are two needle handles 22 , the two needle handles 22 are symmetrically arranged on both sides of the needle body 21 .
[0030] In an optional specific embodiment, taking into account that when the temperature is low, or when the temperature is relatively suitable but a longer intravenous injection is required, the liquid medicine directly entering the human body's blood vessels often causes the patient's limbs to become cold, or even numb and painful. Therefore, the winding belt 32 in this embodiment is configured as a bag-type belt with an opening at one end, and the intravenous injection device also includes a warm liquid layer. When the warm liquid layer generates heat, it is set in the winding belt 32 through the opening.
[0031] Specifically, the warm liquid layer can be a warm liquid layer containing ingredients such as iron powder, carbon powder, salt and water; when the warm liquid layer is sealed in plastic to isolate it from the air, the warm liquid layer does not work, but when it is taken out of the plastic and exposed to the air, it will start to work and generate heat.
[0032] In specific implementation, the heating time of the warm liquid layer can be set between 3 hours and 6 hours, and except for the stage when heating just starts working and is about to stop heating, the warm liquid layer can be regarded as constant temperature heating; in specific implementation, the average heating temperature of the warm liquid layer (the average heating temperature is generally also the average value of the heating temperatures excluding the stage when heating just starts working and is about to stop heating) can be set between 35°C and 45°C.
[0033] In summary, the intravenous injection device implemented in the utility model is provided with a reel 3 that can be put on the outside of the infusion tube 1, and the reel measure 31 in the reel 3 has a first state in the shape of a ruler and a second state in the shape of a tape measure, so that the intravenous injection device can have sufficient operating space when the medical staff performs the needle insertion operation (the reel 3 is in the first state, and the infusion tube 1 can maintain a longer extension length, thereby generating sufficient operating space), and can also reel the infusion tube 1 at a suitable position (generally reeled on the back of the patient's hand or wrist) when the infusion tube 1 is fixed after the insertion, thereby achieving simple and effective fixation of the infusion tube 1 at the reeling position (the infusion tube 1 can be fixed by taping twice at the reeling-in and reeling-out positions of the reel formed by reeling, or by taping once across the diameter of the reel formed by reeling), which is highly practical and flexible.
[0034] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention of the utility model.
