DETAILED DESCRIPTION

[0021] See also Figure 1 , Figure 2 as well as Figure 3 The utility model discloses a three-liter light-shielding bag, comprising a light-shielding bag body 1, the light-shielding bag body 1 is used to cover a three-liter bag 2, the lower end of the light-shielding bag body 1 has an opening 11, a sealing assembly 3 is provided at the opening 11, the sealing assembly 3 comprises a pendant sling 31 and a connecting hole 32, the pendant sling 31 and the connecting hole 32 are respectively arranged on opposite sides of the opening 11 of the light-shielding bag body 1, the pendant sling 31 comprises a connecting strip 311 fixedly connected to one side of the lower end of the light-shielding bag body 1 and a counterweight 312 fixedly connected to the end of the connecting strip 311 away from the light-shielding bag body 1, the pendant sling can be inserted into the connecting hole 32 so that the opposite sides of the opening 11 of the light-shielding bag body 1 are closed together under the gravity of the pendant sling 31. When in use, the three-liter bag 2 is placed into the light-shielding bag body 1 through the opening 11. A sealing assembly 3 is provided at the opening 11 of the light-shielding bag body 1 so that the three-liter bag 2 can be closed after being placed in, thereby completely covering the three-liter bag to prevent decomposition in the light.

[0022] When in use, the shading bag body 1 is placed in the three-liter bag 2 through the opening 11. In this embodiment, the shading bag body 1 is made of coated shading cloth. Since the three-liter bag 2 needs to be hung during infusion, a hanging hole 21 is provided at the top of the three-liter bag 2, and an arc-shaped opening 14 is provided at the top of the shading bag body 1 corresponding to the hanging hole 21. When the three-liter bag 2 is hung, since the arc-shaped opening 14 is provided at the hanging hole 21, the hanging hole 21 can be left uncovered, which does not affect the hanging of the three-liter bag 2. After the three-liter bag 2 is hung, the opening 11 can be closed by inserting the connecting strips 311 into the corresponding connecting holes 32. In this embodiment, the connecting strips 311 and the counterweight 312 are fixed by bonding, and the connecting strips 311 and the shading bag body 1 are also fixed by bonding. In order to facilitate the insertion of the connecting strips 311 into the connecting holes 32, the connecting strips 311 are flexible connecting strips. By designing the connecting strip 311 to be flexible, it is easier to bend, and it is more convenient to insert it into the connecting hole 32. Since the three-liter bag 2 is provided with multiple interfaces, there are multiple connecting strips 311 and multiple connecting holes 32, and the multiple connecting strips 311 correspond to the multiple connecting holes 32 one by one, and the multiple connecting strips 311 are arranged at intervals along the width direction of the light-shielding bag body 1. In this embodiment, since the number of interfaces of the three-liter bag 2 is three, the number of connecting strips 311 and the number of connecting holes 32 are both set to four. The spaced arrangement of the connecting strip 311 and the connecting hole 32 can reserve the position of the interface, and the corresponding connecting strips 311 and the connecting hole 32 at the same position are plugged in when assembled, which can achieve better connection effect without generating too much gap. At the same time, in order for medical staff to understand patient information, a card bag 15 for placing an infusion card is provided on an outer side of the light-shielding bag body 1, and the medical staff can install the patient's infusion card in the card bag 15. In order to facilitate medical staff to observe, there is no need to take out the infusion card. In this embodiment, the card bag 15 is designed to be transparent plastic, which makes it more convenient for medical staff to check.

[0023] In order to facilitate medical staff to check the remaining amount in the three-liter bag 2, an observation window 12 is provided on the side of the light-shielding bag body 1. In order to cover the observation window 12 and facilitate observation by medical staff, a cover 4 for opening and closing the observation window 12 is also provided on the side of the light-shielding bag body 1. The covering area of ​​the cover 4 is larger than the area of ​​the observation window 12. The top of the cover 4 is fixedly connected to the surface of the light-shielding bag body 1, and the bottom of the cover 4 is detachably connected to the surface of the light-shielding bag body 1. Specifically, a Velcro sub-component 41 is fixed at the bottom of the cover 4, and a Velcro mother component 13 adapted to the Velcro sub-component 41 is provided on the outer surface of the light-shielding bag body 1 at the bottom of the observation window 12. Through this design, the bottom of the cover 4 can be bonded to the outer surface of the light-shielding bag body 1 through the Velcro sub-component 41 and the Velcro mother component 13 during normal infusion. At this time, the observation window 12 is in a fully closed state. When the medical staff needs to observe the remaining amount of liquid in the three-liter bag 2, the cover 4 can be opened to observe. After a period of infusion, the nutrient solution in the three-liter bag 2 gradually decreases. When the medical staff pulls the cover 4, it is easy to pull the entire light-shielding bag body 1 at the same time. Therefore, the medical staff usually needs to hold the light-shielding bag body 1 with one hand and then pull the cover 4 with the other hand, which is slightly inconvenient to operate. However, in this embodiment, the counterweight 312 set on the connecting strip 311 can exert a downward gravity on the light-shielding bag body 1. Therefore, the medical staff can provide a certain resistance when pulling the cover 4. When pulling the cover 4, the medical staff can pull the cover 4 without holding the light-shielding bag body 1 with their hands, which is more convenient.

[0024] Please continue to participate Figure 4 and Figure 5 During infusion, the infusion puncture tip needs to be inserted into the infusion socket 22. Since the infusion time of the patient is usually long, the infusion puncture tip may become loose during the infusion process, causing the liquid in the three-liter bag 2 to leak out. Therefore, a limiting device 5 is also provided on the infusion socket 22 of the three-liter bag 2 to limit the infusion puncture tip from being separated from the infusion socket 22. Since the infusion puncture tip is a common medical device, the specific structure is not described in detail here. Specifically, the limiting device 5 includes a fixed seat 52, a limiting member 53 rotatably connected to the fixed seat 52, and an elastic member 54 provided between the fixed seat 52 and the limiting member 53 to drive the lower side of the limiting member 53 to flip toward the side of the infusion puncture tip.

[0025] In order to realize the rotational connection between the stopper 53 and the fixing seat 52, the implementation method given in this embodiment is to set a mounting seat 521 on the outer side of the fixing seat 52, and set a connecting seat 531 adapted to the mounting seat 521 on the stopper 53, and the connecting seat 531 and the mounting seat 521 are rotationally connected through a connecting member 55. Specifically, in this embodiment, the connecting member 55 is a rotating shaft. When the infusion puncture head is not inserted into the infusion socket 22, the stopper 53 is turned toward the side of the infusion socket 22 by the elastic force of the elastic member 54 until it abuts against the infusion socket 22. When the three-liter bag 2 is connected to the infusion puncture head for use, the lower part of the limiting member 53 is first opened to overcome the elastic force of the elastic member 54 to the side away from the infusion socket 22, and then the infusion puncture head is inserted until the outer edge of the infusion puncture head abuts against the lower end of the infusion socket 22, and then the limiting member 53 is released, and the limiting member 53 is reset under the elastic force of the elastic member 54. In this embodiment, a limiting portion 531 bent toward the infusion puncture head is formed at the end of the limiting member 53. When the limiting member 53 rotates under the elastic force of the elastic member 54 until the limiting portion 531 abuts against the outside of the infusion puncture head, the limiting portion 532 is located at the lower side of the outer edge 32 in this state, so that the limiting member 53 can limit the downward movement of the infusion puncture head to prevent the infusion puncture head from falling off due to looseness.

[0026] In order to enable the limiting device 5 to be reused with other three-liter bags 2, the limiting device 5 and the infusion socket 22 are designed to be detachably connected in this embodiment. The specific detachable connection method is a threaded connection, an external thread 221 is provided outside the infusion socket 22, and a threaded hole 51 adapted to the external thread 221 is provided in the limiting device 5. The threaded hole 51 and the external thread 221 are threadedly matched to enable the limiting device 5 to be detachably connected with the infusion socket 22. In this embodiment, the threaded hole 51 is provided on the fixing seat 52. When the blood transfusion is completed, the limiting device 5 can be removed from the infusion socket 22, and when used for other three-liter bags 2, the limiting device 5 can be installed on the infusion socket 22 of other three-liter bags 2. This design is convenient and quick to disassemble and install, and at the same time improves the utilization rate of the limiting device 5 and reduces the use cost.

[0027] The above is only an embodiment of the utility model, and the common knowledge such as the known specific structure and characteristics in the scheme is not described in detail here. It should be pointed out that for those skilled in the art, several deformations and improvements can be made without departing from the structure of the utility model, which should also be regarded as the protection scope of the utility model, and these will not affect the effect of the implementation of the utility model and the practicality of the utility model.
