Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of medical infusion bags, and particularly relates to a structure of an upright polypropylene blend infusion bag. Background Art
[0002] Intravenous infusion is a medical procedure that directly delivers fluids, drugs, or nutrients into a patient's bloodstream through a vein. This method can quickly deliver therapeutic substances throughout the body and is particularly important for patients who cannot absorb them through oral or intramuscular injection. The upright polypropylene blend infusion bag is the most widely used infusion container at present. It is usually made by blending polypropylene (PP) with other polymer materials to provide better physical and chemical properties. Currently, the commonly used infusion bags are generally divided into two structural forms. One is the bottle structure. This structure has a high bottle body strength and can stand upright on the table during medical staff operation, thus avoiding environmental pollution. However, during infusion, due to the decrease in internal pressure, the bottle body deforms, affecting the infusion pressure. The other is the bag structure. During infusion, the bag body maintains deformation, thus avoiding the influence on the infusion pressure. However, this structure has a low bottle body strength and can only be placed in a tilted manner. Content of the Utility Model
[0003] The purpose of the utility model is to provide a structure of an upright polypropylene blend infusion bag to solve the problem proposed in the above background art that the commonly used infusion bags are generally divided into two structural forms. One is the bottle structure. This structure has a high bottle body strength and can stand upright on the table during medical staff operation, thus avoiding environmental pollution. However, during infusion, due to the decrease in internal pressure, the bottle body deforms, affecting the infusion pressure. The other is the bag structure. During infusion, the bag body maintains deformation, thus avoiding the influence on the infusion pressure. However, this structure has a low bottle body strength and can only be placed in a tilted manner.
[0004] To achieve the above purpose, the utility model provides the following technical solution: A structure of an upright polypropylene blend infusion bag, including a soft bag body. A sealing edge is provided along the outer edge of the soft bag body. A mouth tube is provided at the middle position of the upper end of the soft bag body. A base is provided below the soft bag body. Connecting rods are provided on both sides of the upper surface of the base. Connecting edges are provided on both sides of the soft bag body and outside the sealing edge. The connecting edges are fixedly connected to the connecting rods by hot pressing. A hook is provided at the lower end of the base.
[0005] Preferably, a reinforcing edge is provided along the outer edge of the upper surface of the base. The outer ends of the two connecting rods are fixedly connected to the reinforcing edge. A groove is opened upward on the lower wall of the base. The hook is arranged inside the groove. A folding seat is connected between one side of the hook and the groove.
[0006] Preferably, the number of the connecting rods is two. The inner ends of the two connecting rods are provided with bevel cutting grooves. The upper end of the connecting edge is provided with a closed end, and the upper ends of the two connecting rods abut against the inside of the closed end.
[0007] Preferably, a sealing seat is provided at the lower end of the mouth tube, and the sealing seat is fixedly connected with the sealing edge by hot pressing.
[0008] Preferably, the base and the connecting rod are of a rigid polyvinyl chloride structure integrally formed by injection molding.
[0009] Compared with the prior art, the beneficial effects of the present utility model are as follows: on the basis of the commonly used infusion bag structure at present, a base and a connecting rod structure are provided. The soft bag body is arranged on the base through the connecting rod, so that it can stand upright on the table during the operation of medical staff, thereby avoiding environmental pollution. During infusion, the bag body keeps deforming, thereby avoiding the influence on the infusion pressure. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.
[0017] Please refer to Figures 1-5, the present utility model provides a structure of a vertical polypropylene blended infusion bag, which includes a soft bag body 1. A sealing edge 2 is provided along the outer edge of the soft bag body 1. A mouth tube 3 is provided at the middle position of the upper end of the soft bag body 1. A base 4 is provided below the soft bag body 1. Connecting rods 5 are provided on both sides of the upper surface of the base 4. Connecting edges 6 are provided on both sides of the soft bag body 1 and outside the sealing edge 2. The connecting edge 6 is fixedly connected to the connecting rod 5 by hot pressing. A hook 7 is provided at the lower end of the base 4.
[0018] During use, the soft bag body 1 is composed of two polypropylene films, which are sealed into a bag-like structure that can hold liquid through the sealing edge 2. The mouth tube 3 is hermetically connected to the upper end of the soft bag body 1 through the sealing edge 2. Connecting rods 5 are arranged on the base 4, and the connecting rods 5 are correspondingly arranged on both sides of the soft bag body 1. Connecting edges 6 are arranged outside the sealing edges 2 on both sides, and the connecting edge 6 is fixedly connected to the connecting rod 5 by hot pressing. Thus, the soft bag body 1 is supported by the base 4 and the connecting rods 5. The soft bag body 1 is vertically arranged on the table through the base 4, which is convenient for medical staff to add medicine. A hook 7 is provided at the lower end of the base 4, and the hook 7 is hooked to an external suspension device, so as to suspend the whole infusion bag, and then infusion is carried out.
