Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to an expandable infusion bag. Background Art

[0002] Infusion bags are a type of medical consumables, mainly used in hospitals and other medical facilities to provide patients with fluids, electrolytes, nutrients, drugs, etc. through intravenous injection. Infusion bags are usually made of medical-grade plastics such as polyvinyl chloride, polypropylene, polyethylene and other materials, with good biocompatibility and sealing properties, which can ensure stable storage and safe infusion of drugs. Light-sensitive drug solutions refer to those drug solutions that will undergo chemical structure changes after exposure to light, resulting in decreased drug efficacy, increased toxicity or new side effects. However, the infusion bag is not equipped with a shading structure to prevent light-sensitive drug solutions from being exposed to light, which will reduce the efficacy of the drug solution. After the infusion bag is soaked and sterilized, it is directly wrapped in a light-shielding shell, which makes it difficult for the moisture on the surface of the infusion bag to dry quickly.

Example 1

[0024] The fixing assembly includes: a connecting block 2 connected to a side of the light-shielding shell a1 close to the light-shielding shell b101, a connecting rod 201 connected to the connecting block 2 on a side away from the light-shielding shell a1, a fixing plate 202 connected to the top of the infusion bag 102, a connecting hole 203 matching with the connecting rod 201 is provided on one side of the fixing plate 202, a fixing rod 204 connected to a side of the light-shielding shell b101 close to the light-shielding shell a1, a fixing hole 205 is provided on a side of the fixing rod 204 away from the light-shielding shell b101, a positioning rod 206 is connected to a side of the light-shielding shell a1 close to the light-shielding shell b101, and a positioning hole 207 matching with the positioning rod 206 is provided on one side of the fixing plate 202.

[0025] When fixing the infusion bag 102, align the connecting rod 201 with the connecting hole 203, and then let the connecting rod 201 pass through the connecting hole 203. After passing through the connecting hole 203, the connecting rod 201 will enter the fixing hole 205, so as to fix the infusion bag 102 between the light-shielding shell a1 and the light-shielding shell b101, and the positioning rod 206 will pass through the positioning hole 207, so as to further fix the infusion bag 102. Example 2

[0026] On the basis of Example 1, the spreading component includes: a connecting plate 3 connected to both sides of the light-shielding shell a1, a slide rail 301 opened on one side of the connecting plate 3, a slide rod 302 connected to both sides of the light-shielding shell b101 and cooperating with the slide rail 301, the outer end of the slide rod 302 is provided with a thread, and the thread is engaged with a nut 303 connected to the outer end of the slide rod 302.

[0027] To separate the light-shielding shell a1 and the light-shielding shell b101, rotate the nut 303 in the forward direction to allow the nut 303 to gradually leave the slide bar 302 so that the nut 303 will not contact the surface of the connecting plate 3, thereby allowing the slide bar 302 to slide within the range of the slide rail 301, and the movement of the slide bar 302 will move the light-shielding shell b101, thereby separating the light-shielding shell a1 and the light-shielding shell b101, thereby stretching the light-shielding shell a1 and the light-shielding shell b101 apart, and drying the moisture of the infusion bag 102. When the light-shielding shell b101 is to be fixed, rotate the nut 303 in the reverse direction to allow the nut 303 to contact the surface of the connecting plate 3, thereby fixing the distance between the light-shielding shell a1 and the light-shielding shell b101. Example 3

[0028] On the basis of Example 1, a plurality of pins 103 are connected to one side of the light-shielding shell a1 close to the light-shielding shell b101, and a plurality of pin holes 104 matching with the pins 103 are provided on one side of the light-shielding shell b101 close to the light-shielding shell a1. An opening 105 is provided at the bottom of both the light-shielding shell a1 and the light-shielding shell b101. The bottom of the infusion bag 102 passes through the opening 105 and protrudes from the bottom of the light-shielding shell a1 and the light-shielding shell b101. The surface of the infusion bag 102 located at the opening 105 is connected to a limiting ring 106, and the inner wall of the opening 105 is connected to a fixing ring 107 matching with the limiting ring 106.

[0029] The progressive fit between the pin 103 and the pin hole 104 can be used to fix the light-shielding shell a1 and the light-shielding shell b101, thereby protecting the infusion bag 102, and the limiting fit between the limiting ring 106 and the fixing ring 107 can limit and fix the infusion bag 102 to prevent the infusion bag 102 from leaking out of the opening 105 if it is not firmly fixed.

[0030] The specific workflow is:

[0031] The progressive cooperation between the pin 103 and the pin hole 104 can cooperate and fix the light-shielding shell a1 and the light-shielding shell b101, so as to protect the infusion bag 102, and the limiting cooperation between the limiting ring 106 and the fixing ring 107 can limit and fix the infusion bag 102, so as to prevent the infusion bag 102 from leaking out of the opening 105 when it is not firmly fixed. When fixing the infusion bag 102, align the connecting rod 201 with the connecting hole 203, and let the connecting rod 201 pass through the connecting hole 203 after alignment. After passing through the connecting hole 203, the connecting rod 201 will enter the fixing hole 205, so as to fix the infusion bag 102 between the light-shielding shell a1 and the light-shielding shell b101, and the positioning rod 206 will pass through the positioning hole 207, so as to further fix the infusion bag 102;

[0032] To separate the light-shielding shell a1 and the light-shielding shell b101, rotate the nut 303 in the forward direction to allow the nut 303 to gradually leave the slide bar 302 so that the nut 303 will not contact the surface of the connecting plate 3, thereby allowing the slide bar 302 to slide within the range of the slide rail 301, and the movement of the slide bar 302 will move the light-shielding shell b101, thereby separating the light-shielding shell a1 and the light-shielding shell b101, thereby allowing the light-shielding shell a1 and the light-shielding shell b101 to be spread apart for drying, and when the light-shielding shell b101 is to be fixed, rotate the nut 303 in the reverse direction to allow the nut 303 to contact the surface of the connecting plate 3, thereby fixing the distance between the light-shielding shell a1 and the light-shielding shell b101.
