Description

Technical Field

[0001] The utility model relates to the technical field of medical clinical equipment, in particular to a light-proof infusion set. Background Art

[0002] Light-proof drugs need to be protected from light during production, transportation, and infusion to prevent adverse reactions such as changes in drug properties after exposure to light. For example, in the infusion of drugs such as sodium nitroprusside and nifedipine, not only a special light-proof infusion device is required, but also a light-proof bag needs to be placed outside the infusion bag to ensure that the drugs will not be exposed to light during the infusion process. However, during use, traditional light-proof bags have low transparency, and it is difficult to see the specific information of the drugs in the bag during infusion. The bag can only be removed for inspection. Therefore, a light-proof bag that is easy to check the drug information is needed.

[0003] The patent publication number is CN219630140U, and the authorization announcement date is September 5, 2023. A light-proof infusion set has a simple bag structure and low cost. A round hole hanging ear is set on the top; but when the infusion bag is hung, the hanging ear of the light-proof infusion set is easily deformed or even broken due to the heavy infusion bag. The patent publication number is 218793362U, and the authorization announcement date is April 7, 2023. A multifunctional light-proof infusion set includes a container shading area and an infusion set shading area; the container shading area and the infusion set shading area are an integrated structure. This integrated structure is not convenient for infusion bags and infusion tubes, and the droplet regulator cannot be exposed for use. The overall structure is complex and large.

[0017] The following is a further description of the specific implementation of the structural schematic diagram of a light-shielding infusion device of the utility model in combination with the embodiments. The following embodiments are only used to more clearly illustrate the technical solution of the utility model, and cannot be used to limit the protection scope of the utility model; ordinary technicians in the relevant technical field can also make various changes and modifications without departing from the spirit and scope of the utility model, so all equivalent technical solutions also belong to the scope of the utility model, and the patent protection scope of the utility model should be defined by each claim.

[0018] Example

[0019] Figure 1-2 The schematic diagram of the structure of the light-proof infusion device of the utility model is shown.

[0020] The present embodiment provides a light-proof infusion pump, comprising a light-proof bag body 1 which is entirely opaque, a pair of hanging ears 2 being provided on the upper portion of the light-proof bag body, a thin longitudinal visible window 3 being provided on the surface of the light-proof bag body 1, the lower end of the light-proof bag body 1 being converged to form a convergence port 4, and the convergence port 4 being bonded with a downward external threaded connector 5; the infusion pump also comprises a light-proof tube body 6, the light-proof tube body 6 comprises a tube body connector 60 and a retractable corrugated tube body 61 integrally formed with the tube body connector 60, the corrugated tube body 61 being a tube body structure with a break on the side and the tube body curled in the radial direction, and the tube bodies on both sides of the break of the corrugated tube body 61 in the curled state overlap each other.

[0021] To prevent the infusion tube from falling off from the light-proof tube body, Figure 2 As shown, a plurality of mutually connected clamping columns 62 and clamping holes 63 are evenly distributed on both sides of the overlapping part of the corrugated tube body 61. The clamping columns and clamping holes are arranged on the corrugated inclined surface, and are clamped and fixed by the clamping columns and clamping holes at the overlapping part. The number and spacing of the clamping columns and clamping holes are set according to actual conditions.

[0022] Figure 3 As shown, the bellows body 61 is further divided into an upper body 610 and a lower body 611, and the upper body 610 and the lower body 611 are connected by two symmetrical connecting strips 64. The connecting strip is located at the fixed position of the drop regulator, and the upper body and the lower body of the bellows body structure are telescopically adjusted according to the length of the upper body and the lower body of the dropper, so that it is suitable for most infusion tubes and has good practicality. The outer wall surface of the tube body connector 60 has vertical anti-slip grooves for easy screwing.

[0023] When in use, the infusion bag is placed into the light-proof bag body 1 from the upper opening, and the lower port of the infusion bag is placed until the bundle mouth. The upper end socket of the infusion tube is inserted upward from the broken end of the corrugated tube body into the tube body connector and then inserted into the infusion bag; the tube body connector is then connected and fixed with the external thread connector.

[0024] The existing light-proof bag is made of thin material, and the infusion bag is heavy when in use. The hanging part of the light-proof bag is easily deformed or even broken, causing danger. For this reason, the upper edge of the light-proof bag 1 and the ear 2 are both folded inwardly by the bag material to form a double-layer structure with a cavity, and the cavity is inflated to form an inflated shape; the double-layer inflated structure makes its upper structure stronger and safer when hanging.

[0025] In addition, the visual window 3 is in the shape of a narrow strip, and a ruler scale is printed on its side, so that the infusion volume can be more clearly known.
