Description

Technical Field

[0001] The utility model belongs to the technical field of infusion bags, and in particular relates to an integrated medicine dispensing infusion bag. Background Art

[0002] The Chinese patent with the authorization announcement number CN104188801B discloses a powder-liquid dual-chamber infusion bag and its preparation method, which is a ready-to-mix infusion product. The packaging material of this type of product, the powder-liquid dual-chamber infusion bag, refers to an infusion bag made of a multi-layer co-extruded infusion film that is welded and heat-sealed around the bag body, and the internal space is separated by a weak weld heat-sealed (which can be opened by applying pressure). The two chambers of the infusion bag can be used to fill the liquid medicine and sterile powder respectively. Before infusion, the operator only needs to apply a certain pressure to the liquid cavity bag body, open the weak weld part to make the two chambers connected and shake well, so that the sterile liquid medicine and the sterile powder are fully mixed and dissolved, and then the infusion bag can be hung for clinical infusion.

[0003] When the above-mentioned product needs to mix the liquid medicine in the infusion bag, the infusion bag is usually folded, and then the folded infusion bag is pressed to open the weak welding part. However, since there are fewer folded parts when the infusion bag is folded, the pressure required to open the weak welding part cannot be effectively met when pressing. If there are more folded parts, it is easy to apply a greater squeezing force to the infusion bag, causing damage to the infusion bag. Therefore, when using the above-mentioned infusion bag, it is difficult to operate the infusion bag to mix the liquid medicine, and it requires a period of training before it can be used.

[0022] In order to make the purpose and advantages of the utility model more clear, the utility model is specifically described in combination with the following embodiments. It should be understood that the following text is only used to describe one or several specific implementations of the utility model, and does not strictly limit the protection scope of the specific request of the utility model.

[0023] like Figure 1-4 As shown, an integrated medication infusion bag includes an infusion bag body 1, on which a weak welding rod 2 is arranged, and the space inside the infusion bag body 1 is divided into two medicine liquid chambers 5 by the weak welding rod 2, and the two medicine liquid chambers 5 respectively store different medicine liquids, and can also store medicine liquids and medicine powders. When it is needed, the infusion bag body 1 is pressed to allow the medicine liquid inside the infusion bag body 1 to apply pressure to the weak welding rod 2, and under the action of the pressure, the weak welding rod 2 is flushed open, so that the two medicine liquid chambers 5 are connected, and the medicine liquids inside the two medicine liquid chambers 5 can be mixed together to complete the medication.

[0024] At the same time, one end of the infusion bag body 1 is fixedly connected with an infusion part 3 and a liquid inlet part 4. Both the infusion part 3 and the liquid inlet part 4 include a plastic interface fixedly connected to the infusion bag body 1. The two plastic interfaces are respectively connected to two medicine liquid chambers 5. A sealing cover is installed on the plastic interface. When the sealing cover is opened, liquid can be inflowed and outflowed from the medicine liquid chamber 5. When the sealing cover is closed, the medicine liquid chamber 5 can be sealed.

[0025] The core of the present technical solution is that a pressurized airbag 6 is installed inside one of the medicine liquid cavities 5, and an inflation part connected to the pressurized airbag 6 is installed on the outside of the infusion bag body 1. At this time, when it is necessary to mix the medicines in the two medicine liquid cavities 5 together, the pressurized airbag 6 is inflated by the inflation part to expand the pressurized airbag 6, and the inside of the medicine liquid cavity 5 can be pressurized by the inflated pressurized airbag 6 until the weak welding rod 2 is flushed open, so that the two medicines are mixed together. Here, the medicines in the medicine liquid cavity 5 are pressurized by the inflated pressurized airbag 6 to flush the weak welding rod 2 open, which can effectively reduce the difficulty of operating the infusion bag to mix the medicines, and effectively reduce the damage to the infusion bag body 1 caused by excessive squeezing force.

[0026] Here, the pressurized airbag 6 is a hollow bag body, the material of the bag body can be latex, so that the pressurized airbag 6 can maintain a small volume when not inflated, and the pressurized airbag 6 can be directly fixedly connected to the inner wall of the medicine liquid chamber 5, or can be independently installed inside the medicine liquid chamber 5.

[0027] Among them, the inflation part can be an inflation nozzle fixedly connected to the outside of the infusion bag body 1 and connected to the pressurized airbag 6, and the inflation nozzle is used to be connected to the air pump. At this time, when in use, the air pump and the inflation nozzle are connected, and the pressurized airbag 6 can be directly inflated by the air pump, so that the pressurized airbag 6 expands, further reducing the difficulty of use.

[0028] Among them, Figure 1-2As shown, the inflation part can also include an inflation mechanism 7 installed on the outside of the infusion bag body 1 and connected to the pressurized airbag 6. The inflation mechanism 7 can be any one of an air pump and a hand-pinch inflation ball, preferably a hand-pinch inflation ball. At this time, the pressurized airbag 6 can be inflated by pressing the inflation mechanism 7 multiple times. Its structure is relatively simple and the production difficulty is relatively low.

[0029] like Figure 2-3 As shown, in order to reduce costs, the outer side of the infusion bag body 1 is fixedly connected with a connecting inner tube 10 which is connected to the pressurized airbag 6, and the inflation mechanism 7 is equipped with a connecting outer tube 9, and the connecting outer tube 9 is detachably installed on the connecting inner tube 10. At this time, through the setting of the connecting inner tube 10 and the connecting outer tube 9, the inflation mechanism 7 can be removed from the infusion bag body 1, so that the inflation mechanism 7 can be used with multiple infusion bag bodies 1, thereby reducing the cost of use.

[0030] Here, the connection method between the outer tube 9 and the inner tube 10 can be a sleeve connection, a clamping connection, or a threaded connection. The present technical solution is preferably a threaded connection, and specifically, the inner wall of the outer tube 9 is provided with an internal thread, and the outer wall of the inner tube 10 is provided with an external thread. The outer tube 9 and the inner tube 10 are threadedly connected together by the internal thread and the external thread, thereby making the connection between the outer tube 9 and the inner tube 10 relatively simple, and the air tightness is better after the connection.

[0031] To facilitate user operation, an air guide tube 8 is installed on the inflation mechanism 7, and one end of the air guide tube 8 away from the inflation mechanism 7 is fixedly connected to the outer tube 9. Through the arrangement of the air guide tube 8, the inflation mechanism 7 can have a larger activity space, which is convenient for users to operate the inflation mechanism 7.

[0032] The working principle of the utility model is as follows: when it is necessary to mix the medicinal liquids inside the two medicinal liquid cavities 5 together, the pressurized airbag 6 is inflated through the inflation part to expand the pressurized airbag 6, and the medicinal liquid inside the medicinal liquid cavity 5 is pressurized by the expanded pressurized airbag 6 until the weak welding rod 2 is flushed open, so that the two medicinal liquids are mixed together.

[0033] The above is only a preferred embodiment of the present invention. It should be noted that, for ordinary technicians in the technical field, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be regarded as the protection scope of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to the conventional means in the field unless otherwise specified and limited.
