Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of medical equipment, and specifically relates to a multi-cavity infusion bag. Background Art
[0002] Currently, when preparing liquid medicine to be injected into the patient's body in clinical practice, the medicine is usually injected into an infusion bag filled with saline or other solutions. However, during the preparation of chemotherapy drugs and the injection of chemotherapy drugs into the infusion bag, there is a risk of drug leakage and environmental pollution, which also increases the risk of occupational exposure for nurses preparing the drugs. Chemotherapy drugs also need to be prepared in advance, and currently chemotherapy drugs also require nurses or practicing pharmacists to operate in a dedicated biosafety cabinet, which reduces treatment efficiency and increases economic costs.
[0003] Therefore, it is necessary to design an infusion bag that can be pre-filled with medicine, which can quickly mix the separately stored medicine with the solution when used. This infusion bag is specifically a multi-cavity infusion bag. Utility Model Content
[0004] In order to overcome the problems raised in the background technology, the utility model adopts the following technical solutions:
[0005] A multi-cavity infusion bag mainly comprises a bag body, a hanging buckle and a pulling strap; the bag body comprises a medicine storage cavity and a solution cavity with medicines preset therein, a partition section is provided between the medicine storage cavity and the solution cavity, the outer walls of the bag body on both sides of the partition section are squeezed and engaged with each other so that the medicine storage cavity and the solution cavity are not connected; the hanging buckle is connected to the top of the outer wall of the medicine storage cavity so that the medicine storage cavity is located above the solution cavity when the bag body is hung; the pulling strap has one end connected to the outer wall of one side of the solution cavity, and the other end of the pulling strap bypasses the medicine storage cavity and is connected to the outer wall of the other side of the solution cavity so as to cover the hanging buckle.
[0006] Furthermore, the projection of the pull strap on a parallel plane is a centrally symmetrical figure, and the pull strap is provided with a through hole at the center of symmetry, so that when in use, the pull strap can be moved toward the ground so that the buckle passes through the through hole and connects with the buckle in the environment, thereby fixing the position of the infusion bag in space.
[0007] Furthermore, two adhesive structures are symmetrically provided on one side of the pull strap, and the adhesive structure can be one of Velcro or adhesive layers. The midpoint of the line connecting the symmetry centers of the two adhesive structures is the symmetry center of the pull strap. The adhesive structures are arranged on both sides of the through hole, and the two adhesive structures move toward each other and adhere to each other, so that the buckle cannot pass through the through hole, so that the user must separate the adhesive structure before hanging the infusion bag when using it.
[0008] Furthermore, the bag body also includes a limiting belt, both ends of which are connected to the outer wall of the medicine storage cavity, so that a limiting channel is formed between the limiting belt and the bag body, and the pulling belt is sleeved on the limiting channel.
[0009] Furthermore, the number of the limiting belts is at least one pair, and the number of each pair of limiting belts is two, and the two limiting belts are symmetrically connected to the outer walls on both sides of the medicine storage cavity.
[0010] Furthermore, the pull strap includes an initial state. In the initial state, the two adhesive structures are bonded together, and the through holes and the hooks are spatially distributed on both sides of the adhesive structures.
[0011] Furthermore, the pull strap includes a use state, in which one of the adhesive structures is away from the other adhesive structure, and the two adhesive structures are separated and move through the limiting channel in a direction away from the hook, so that the hook passes through the through hole and is exposed to the outside.
[0012] Furthermore, the symmetry center of the pull strap moves toward the medicine storage cavity and finally abuts against the bag body. The portion of the pull strap passing through the limiting channel forms a accommodating space with the outer wall of the bag body. The pull strap is connected to both sides of the bag body, so the number of accommodating spaces is two, and the diameter of the inscribed circle of the accommodating space is not less than 15 mm.
[0013] Furthermore, at least one end of the pulling belt moves in a direction away from the plane where the bag body is located, and the outer walls of both sides of the bag body in the separation section are separated, so that the drug storage cavity is connected with the solution cavity.
[0014] Beneficial effects of the utility model:
[0015] 1. By presetting the medicine in the medicine storage cavity and the solution in the solution cavity, the medicine solution does not need to be configured by itself, thereby avoiding the configuration operation before infusion, and completely eliminating the risk of pollution or occupational exposure caused by leakage of powder or other highly polluting drugs. Therefore, the utility model has a better use effect than the existing technology.
[0016] 2. A partition section is provided between the drug storage cavity and the solution cavity. The pull strap has two different forms in the initial state and in the use state. By setting the adhesive structure, the pull strap in the initial state can cover the hanging buckle. If the medical staff wants to hang the bag body for infusion, they must first separate the adhesive structures on both sides, and then pull down the pull strap through the limiting channel so that the hanging buckle can extend from the through hole. The pulled pull strap and the bag body form a holding space that can accommodate the fingers of the medical staff in the use state. The medical staff inserts their fingers into the holding space and pulls them to both sides, which can destroy the separation effect of the partition section on the solution cavity and the drug storage cavity, so that the drug and the solution are mixed, and the operation is simple.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Those skilled in the art can easily understand other advantages and functions of the utility model from the contents disclosed in this specification.

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0025] A multi-chamber infusion bag, such as Figure 1-5As shown, it mainly includes a bag body 1, a hanging buckle 2 and a pulling belt 3; the bag body 1 includes a drug storage cavity 11 and a solution cavity 12 with drugs preset therein, a partition section 13 is provided between the drug storage cavity 11 and the solution cavity 12, and the bag body 1 is in the extrusion joint of the outer walls on both sides of the partition section 13 so that the drug storage cavity 11 and the solution cavity 12 are not connected; the hanging buckle 2 is connected to the top of the outer wall of the drug storage cavity 11 so that the drug storage cavity 11 is located above the solution cavity 12 when the bag body 1 is suspended; the pulling belt 3 has one end connected to the outer wall of one side of the solution cavity 12, and the other end of the pulling belt 3 bypasses the drug storage cavity 11 and is connected to the outer wall of the other side of the solution cavity 12 to cover the hanging buckle 2.
[0026] In some embodiments of the present application, Figure 1-5 As shown, the projection of the pull strap 3 on the parallel plane is a centrally symmetrical figure, and the pull strap 3 is provided with a through hole 31 at the symmetry center, so that when in use, the pull strap 3 can be moved toward the ground so that the hook 2 passes through the through hole 31 and connects with the hook 2 in the environment, thereby fixing the position of the infusion bag in space.
[0027] In some embodiments of the present application, Figure 1-5 As shown, two adhesive structures 32 are symmetrically arranged on one side of the pull strap 3. The adhesive structure 32 can be one of Velcro or adhesive coating. The midpoint of the line connecting the symmetry centers of the two adhesive structures 32 is the symmetry center of the pull strap 3. The adhesive structures 32 are arranged on both sides of the through hole 31. The two adhesive structures 32 move toward each other and adhere to each other, so that the hook 2 cannot pass through the through hole 31, so that the user must first separate the adhesive structure 32 before hanging the infusion bag when using it.
[0028] In some embodiments of the present application, Figure 1-5 As shown, the bag body 1 also includes a limiting belt 14, both ends of which are connected to the outer wall of the medicine storage cavity 11, so that a limiting channel 15 is formed between the limiting belt 14 and the bag body 1, and the pulling belt 3 is sleeved on the limiting channel 15. The limiting channel 15 can evenly distribute the force of the pulling belt 3 to the outer wall of the medicine storage cavity 11 when the user pulls the pulling belt 3 to both sides of the bag body 1, so that the separation state of the partition section 13 is easier to be released.
[0029] In some embodiments of the present application, Figure 1-5 As shown, the number of the limiting belts 14 is at least one pair, and the number of each pair of limiting belts 14 is two. The two limiting belts 14 are symmetrically connected to the outer walls of the medicine storage cavity 11 on both sides, and are placed horizontally on the outer wall of the medicine storage cavity 11, and their horizontal direction is parallel to the ground. The two ends of the limiting belt 14 are bonded or melted to the bag body 1, and the part between the two ends of the limiting belt 14 abuts against the outer wall of the medicine storage cavity 11, so that the pulling belt 3 can be better constrained in the limiting channel 15 between the limiting belt 14 and the bag body 1.
[0030] In some embodiments of the present application, Figure 1-5 As shown, the pulling tape 3 includes an initial state. In the initial state, the two adhesive structures 32 are bonded together, and the through hole 31 and the hook 2 are spatially distributed on both sides of the adhesive structure 32. At this time, when the pulling tape 3 moves toward the solution chamber 12, the adhesive structure 32 will abut against the top of the hook 2, so that the hook 2 and the through hole 31 cannot contact each other, thereby preventing the hook 2 from being exposed in the event of accidental touch. Therefore, if the user wants to hang up the bag body 1, the parts of the pulling tape 3 where the adhesive structure 32 are provided must be separated from each other. This is also a prerequisite for subsequently pulling the pulling tape 3 and constructing the accommodating space 33.
[0031] In some embodiments of the present application, Figure 1-5 As shown, the pull strap 3 includes a use state. In the use state, one adhesive structure 32 is away from the other adhesive structure 32, and the two adhesive structures 32 are separated and move through the limiting channel 15 in a direction away from the hook 2, so that the hook 2 passes through the through hole 31 and is exposed to the outside.
[0032] In some embodiments of the present application, Figure 1-5 As shown, the symmetry center of the pull belt 3 moves toward the medicine storage cavity 11 and finally abuts against the bag body 1. The portion of the pull belt 3 passing through the limiting channel 15 and the outer wall of the bag body 1 form a receiving space 33. The pull belt 3 is connected to both sides of the bag body 1, so the number of receiving spaces 33 is two, and the diameter of the inscribed circle of the receiving space 33 is not less than 15 mm. The user's fingers can pass through the receiving space 33, and there is a force point for pulling the pull belt 3 to both sides perpendicular to the plane where the infusion bag is located, which is conducive to the user to quickly connect the medicine storage cavity 11 with the solution cavity 12 and mix the medicine and the solution.
[0033] In some embodiments of the present application, Figure 1-5 As shown, at least one end of the pulling belt 3 moves in a direction away from the plane where the bag body 1 is located, and the outer walls of the bag body 1 on both sides of the partition section 13 are separated. Specifically, the medical staff extends two fingers into the accommodating spaces 33 on both sides of the bag body 1 and pulls in opposite directions, so that the pulling force directly acts on the outer wall of the solution cavity 12 connected to the pulling belt 3, and at the same time, the pulling force is also transmitted through the pulling belt 3 to the outer wall of the drug storage cavity 11 connected to the two ends of the limiting belt 14, so that the bag body 1 that is squeezed and joined between the drug storage cavity 11 and the solution cavity 12 is separated; so that the drug storage cavity 11 and the solution cavity 12 are connected, the bag body 1 is also provided with an infusion tube 4 connecting the solution cavity 12 and the outside, and the number of the infusion tube 4 is at least two, one of the infusion tubes 4 is mainly used to connect the pipeline for infusing the patient, and the other infusion tube 4 is used to inject other drugs into the bag body 1.
