Description

Technical Field

[0001] This utility model relates to the field of infusion components, specifically an anti-slip intravenous infusion set. Background Technology

[0002] Intravenous infusion involves suspending a bottle or infusion bag containing liquid at a high position, using gravity to allow the liquid to flow into a vein through an intravenous infusion set. The infusion set is a crucial component in intravenous infusion. For example, Chinese utility model patent CN108697844A discloses an intravenous infusion set for managing the continuous, airless delivery of intravenous fluid to the patient. The intravenous infusion set includes: a drip chamber; a flexible infusion tubing of sufficient length connecting the lower end of the drip chamber to the patient's end with a standard connector, allowing a needle or catheter to be connected to the patient; a roller clamp disposed between the drip chamber and the standard connector and movable along the length of the flexible infusion tubing; a spike at the upper end of the drip chamber; and a flow regulating stop at its lower end configured to manage the continuous, airless delivery of intravenous fluid to the patient. When installing this type of infusion set, the pointed end is inserted into the rubber stopper of the infusion bottle or bag. The movement of the patient's body position or the movement of the hand receiving the infusion can cause the infusion tubing to shake. The infusion connection achieved solely by inserting the pointed end into the rubber stopper is not very stable. Utility Model Content

[0003] The purpose of this invention is to provide an anti-slip intravenous infusion set. This invention improves the stability of the connection between the infusion set and the stopper by using an extended protrusion structure on the puncture body, thereby enhancing the stability of the intravenous infusion.

[0004] The technical solution of this utility model: an anti-slip intravenous infusion set, including tubing, flow regulator, injection head, drip chamber, and bottle stopper puncture device. The bottle stopper puncture device includes a puncture body with a pointed tip at the front end. An axial groove is provided on the circumferential surface of the puncture body. An elastic sheet is provided in the axial groove. The elastic sheet has a cylindrical part and an extension part. The axial groove has a first groove for the cylindrical part to extend to the outside of the axial groove and a second groove for the cylindrical part to move. An elastic membrane is covered on the opening of the first groove.

[0005] In the aforementioned anti-slip intravenous infusion set, the elastic plate includes a fixed plate body disposed at the bottom of the axial groove, one end of the fixed plate body has an inclined plate body, and the end of the inclined plate body has a supporting plate body; the column part is disposed on the inclined plate body, and the extension part is disposed at the end of the supporting plate body.

[0006] In the aforementioned anti-slip intravenous infusion set, the cylindrical part includes a cylinder disposed on the surface of the inclined sheet, and the upper end of the cylinder has a round head.

[0007] In the aforementioned anti-slip intravenous infusion set, the stopper puncture device also includes a protective sleeve for protecting the tip.

[0008] In the aforementioned anti-slip intravenous infusion set, the surface of the extension section has an arc-shaped structure.

[0009] Compared with the prior art, the advantages of this utility model are:

[0010] 1. When the bottle stopper puncture device of this utility model is in operation, the tip first penetrates the rubber stopper of the infusion bottle or infusion bag. At the same time, the extension part in the axial groove is squeezed by the rubber stopper and retracts into the axial groove. After entering the rubber stopper, the extension part will reset. The first groove is set on the outside of the groove opening. The elastic membrane in the first groove can prevent the liquid in the infusion bottle from flowing into the axial groove through the first groove. To remove the puncture body, press the column part with your finger to deform the elastic sheet, and the extension part retracts into the axial groove. Then, pull out the tip. The movable extension part structure greatly enhances the stability of the connection between the bottle stopper puncture device and the rubber stopper, effectively reducing the problem of loosening of the connection caused by the shaking of the infusion line due to the patient's body position movement or the hand movement during infusion, and providing a higher stability guarantee for the intravenous infusion process.

[0011] 2. The tip is equipped with a protective sleeve. When the intravenous infusion set is not in use, the protective sleeve can prevent the tip from being contaminated or damaged, avoid affecting the puncture effect due to tip damage, and also prevent accidental puncture injury to the user.

Detailed Implementation

[0017] The present invention will be further described below with reference to the accompanying drawings and embodiments, but this should not be construed as limiting the present invention.

[0018] Example: An anti-slip intravenous infusion set, comprising tubing 1, flow regulator 2, injection head 3, drip chamber 4, and stopper puncture device 5, as shown in the attached diagram. Figure 1 As shown, the bottle stopper puncturer 5 includes a puncture body 6, as attached. Figure 2 As shown, the puncture body 6 has a pointed tip 7 at its front end, with multiple fluid outlets on the tip. Liquid enters the tubing through these outlets. The bottle stopper puncturer 5 also includes a protective sleeve 22 to protect the pointed tip 7. When the bottle stopper puncturer is not in use, the protective sleeve is placed on the pointed tip. The puncture body 6 has an axial groove 8 on its circumferential surface, as shown in the attached diagram. Figure 3 As shown, an elastic sheet 11 is installed in the axial groove 8. The elastic sheet 11 has a columnar part 12 and an extension part 13. The surface of the extension part 13 has an arc-shaped structure, which allows for smoother compression by the rubber stopper. The axial groove 8 has a first groove 14 where the extension part 13 extends to the outside of the axial groove 8 and a second groove 15 for the columnar part 12 to move. An elastic membrane 21 is covered on the opening of the first groove 14. When setting the elastic membrane, a medical-grade adhesive is used. The opening of the first groove and the bonding surface of the elastic membrane are first cleaned to remove oil, impurities, etc., to enhance the bonding effect. A thin layer of adhesive is evenly applied to the edge of the opening of the first groove. The cut elastic membrane is accurately covered on the opening and gently pressed to ensure that the elastic membrane is in full contact with the opening and that the bonding is firm. The elastic membrane has a certain degree of extensibility and is not easy to break when the extension part contacts the elastic membrane. The elastic sheet 11 includes a fixed sheet 16 set at the bottom of the axial groove 8, as shown in the attached figure. Figure 4 As shown, one end of the fixed plate 16 has an inclined plate 17, and the end of the inclined plate 17 has a supporting plate 18; the column part 12 is disposed on the inclined plate 17, and the extension part 13 is disposed at the end of the supporting plate 18; the column part 12 includes a cylinder 19 disposed on the surface of the inclined plate 17, and the upper end of the cylinder 19 has a round head 20. When the medical staff's fingers contact the round head and press, the force on the column part will be transmitted to the inclined plate, and finally drive the supporting plate and the extension part to retract into the axial groove. Since the inclined plate is in an inclined state, the column part and the extension part will tilt during movement. Therefore, the first groove and the second groove are both set to be relatively large in size to allow for the movement of the extension part and the column part.

[0019] The working principle of this utility model is as follows: In use, first remove the protective sleeve 22 to expose the tip 7 at the front end of the bottle stopper puncture device 5. Align the tip with the rubber stopper of the infusion bottle or bag and puncture forcefully. At this time, the tip penetrates the rubber stopper first. Simultaneously, the extension portion 13 on the elastic plate 11 within the axial groove 8 is squeezed by the rubber stopper. Because the extension portion is connected to the support plate 18, and the support plate is connected to the fixed plate 16 fixed at the bottom of the axial groove via the oblique plate 17, under pressure, the elastic plate deforms, and the extension portion 13 retracts along the first groove 14 into the axial groove 8. After the tip successfully penetrates the rubber stopper to a certain depth, the squeezing force of the rubber stopper on the extension portion 13 disappears, the elastic plate 11 recovers its deformation, and the extension portion 13 returns to its original position outside the axial groove 8 via the first groove 14. Since the surface of the extension portion has an arc-shaped structure, and the opening of the first groove 14 is covered with an elastic membrane 21, which is adhered to the opening with medical-grade adhesive and is larger than the opening, it can prevent the contents of the infusion bottle from being squeezed. The liquid flows into the axial groove through the first groove; the extension 13 extends into the rubber stopper, greatly enhancing the stability of the connection between the bottle stopper puncture device 5 and the rubber stopper, reducing the problem of loosening caused by the movement of the infusion tubing due to the patient's body position or the hand movements during infusion, and ensuring the stability of the infusion process; after the infusion is completed, if the puncture body 6 needs to be removed, the medical staff press the column part 12 with their fingers; the column part 12 consists of a cylinder 19 set on the surface of the inclined plate 17 and a round head 20 at the upper end. When the fingers contact and press the round head, the force is transmitted to the inclined plate 17, which drives the support plate 18 and the extension 13, causing the elastic plate 11 to deform, and the extension 13 to retract into the axial groove 8. At this time, the tip 7 can be pulled out from the rubber stopper, completing the entire infusion process.
