Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical device technology, and in particular to an integrated sling-type infusion set. Background Technology
[0002] Intravenous infusion therapy, as an indispensable part of modern medicine, plays a vital role in clinical treatment. Traditional drip infusion sets typically consist of three separate components: the main body, the hanging ring, and the sling. The main body holds the infusion fluid; the hanging ring is fixed to the top of the main body and connects to the sling; the sling connects to the hanging ring and suspends the main body. However, this separate structure has some drawbacks: the sling and hanging ring require separate injection molding and extrusion, and assembly is inconvenient, resulting in low production efficiency. Utility Model Content
[0003] Therefore, the purpose of this utility model is to provide an integrated sling and infusion set for improving production efficiency.
[0004] An integrated sling-type infusion set includes a bottle stopper puncturer, a bottle, a drip chamber, a medicine filter, and an infusion needle connected in sequence via a tubing. The bottle includes a bottle cap and a bottle body that are fastened together. A sling is provided on the side wall of the bottle body. The sling and the bottle body are integrally injection molded together.
[0005] Alternatively, the bottle cap may have a sling on its side wall, and the sling may be integrally injection molded with the bottle cap.
[0006] Compared with the prior art, this utility model improves production efficiency by making the sling and bottle cap or bottle body an integrated structure, so that the sling does not need to be assembled separately.
[0007] Furthermore, when the strap is located on the side wall of the bottle body, the end face of the bottle cap facing the bottle body is provided with a fastening groove, and the inner wall of the outer ring of the fastening groove is provided with a protruding ring;
[0008] The bottle body has an inverted buckle ring at the top outer edge, which engages with the convex ring.
[0009] Furthermore, the inverted buckle is provided with a notch, the bottom of which coincides with the outer wall of the bottle;
[0010] The notch extends longitudinally through the inverted buckle, and the connection between the strap and the bottle body is located at the bottom of the notch.
[0011] Furthermore, the sling includes a connecting portion connected to the outer wall of the bottle body, a bent portion connected to the connecting portion, and a middle portion connecting the two bent portions;
[0012] The connecting part is perpendicular to the outer wall of the bottle and its length is greater than the thickness of the outer ring of the fastening groove.
[0013] Furthermore, the thickness of the bent portion is 0.5mm-2mm.
[0014] Furthermore, the bottom of the bottle cap contacts the top of the connector.
[0015] Furthermore, when the strap is located on the side wall of the bottle cap, one side of the strap is on the same plane as the bottom of the bottle cap. Attached Figure Description

[0024] The following detailed description, in conjunction with the accompanying drawings, will further illustrate this utility model. Detailed Implementation
[0025] To facilitate understanding of this utility model, a more complete description will be given below with reference to the accompanying drawings. Several embodiments of this utility model are shown in the drawings. However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that the disclosure of this utility model will be more thorough and complete.
[0026] Please see Figures 2 to 4 An embodiment of this utility model provides an integrated sling-type infusion set, comprising a bottle stopper puncturer 11, a bottle 12, a drip chamber 13, a medicine filter 14, and an infusion needle connected in sequence via a tubing 10. The bottle 12 includes a bottle cap 121 and a bottle body 122 that are fastened together. A sling 1221 is provided on the side wall of the bottle body 122. The sling 1221 and the bottle body 122 are integrally injection molded, so that the sling 1221 does not need to be assembled separately, thereby improving production efficiency.
[0027] In a preferred embodiment of this application, the bottle cap 121 has a fastening groove on the end face facing the bottle body 122, and a protruding ring is provided on the inner wall of the outer ring of the fastening groove;
[0028] The bottle body 122 has an inverted buckle 1222 at the top outer edge, which engages with the convex ring.
[0029] It should be noted that this fastening structure is similar to the fastening structure between a beer bottle and its cap, and is achieved by pressing it together with equipment to achieve a sealing function.
[0030] Please see Figure 3 and Figure 4 In a preferred embodiment of this application, the inverted buckle 1222 is provided with a notch 1223, and the bottom of the notch 1223 coincides with the outer wall of the bottle body 122;
[0031] The notch 1223 extends longitudinally through the inverted buckle 1222, and the connection between the sling 1221 and the bottle body 122 is located at the bottom of the notch 1223.
[0032] It should be noted that the notch 1223 is in the shape of an inverted trapezoid, rectangle, or triangle to facilitate demolding during the injection molding process.
[0033] Please see Figure 3 and Figure 4 In a preferred embodiment of this application, the sling 1221 includes a connecting portion 12211 connected to the outer wall of the bottle, a bent portion 12212 connected to the connecting portion 12211, and a middle portion 12213 connecting the two bent portions;
[0034] The connecting part 12211 is perpendicular to the outer wall of the bottle body 122, and its length is greater than the thickness of the outer ring of the fastening groove.
[0035] Please see Figure 3 and Figure 4 In a preferred embodiment of this application, the thickness of the bending portion 12212 is 0.5mm-2mm, and it can be bent at 90° by relying on the toughness of the plastic.
[0036] Please see Figure 3 and Figure 4 In a preferred embodiment of this application, the bottle body 122 and the bottle cap 121 are made of polypropylene, and the bottom of the bottle cap 121 contacts the top of the connecting part 12211 to limit the bottle cap 121.
[0037] Please see Figure 5 and Figure 6 In a preferred embodiment of this application, a sling 1221a is provided on the side wall of the bottle cap 121. The sling 1221a is integrally injection molded with the bottle cap 121, so that the sling 1221a does not need to be assembled separately, thereby improving production efficiency.
[0038] Furthermore, one side of the sling 1221a is on the same plane as the bottom of the bottle cap 121 to facilitate injection molding.
[0039] In summary, by making the sling 1221 and the bottle cap 121 or the bottle body 122 an integral structure, the sling 1221 does not need to be assembled separately, thereby improving production efficiency.
[0040] In this specification, the various embodiments are described in a progressive manner, with each embodiment focusing on its differences from other embodiments. Similar or identical parts between embodiments can be referred to interchangeably. Furthermore, the above-described embodiments only illustrate several implementation methods of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
