Description

Technical Field

[0001] The utility model relates to the technical field of medical liquid taking devices, and more specifically, to a container conversion cover. Background Art

[0002] In the field of medical dialysis, dialysis fluid is an important liquid for maintaining the life of hemodialysis patients, and its cleanliness and safety are crucial for patients. Currently, dialysis fluid is usually stored in a dedicated liquid carrier bucket and is taken by a specific liquid taking tool. However, there are some deficiencies in the design and use of traditional liquid carrier buckets and liquid taking tools, such as easy contamination during the liquid taking process, inconvenient operation, poor sealing performance, etc. These problems seriously affect the safety and use effect of dialysis fluid.

[0003] Specifically, a traditional liquid carrier bucket usually only has a simple liquid taking port, which is sealed by a rubber plug or other sealing parts. When taking liquid, a special tool is needed to move the sealing part away, and then the liquid taking tool is inserted into the liquid taking port to take liquid. The disadvantage of this method is that the sealing part is easily contaminated, and during the liquid taking process, the liquid taking tool is easily exposed to the external environment, increasing the risk of dialysis fluid being contaminated. Moreover, for volatile dialysis fluid, the liquid evaporation concentration decreases, and the evaporated acidic liquid pollutes the environmental space, which can cause occupational injuries to staff.

[0004] To solve the above problems, some new dialysis fluid taking systems have emerged on the market, including a liquid carrier bucket with a conversion cover. However, there are still some defects in the design and use of these systems. For example, some conversion covers are relatively complex in structure, inconvenient to operate, and have poor sealing performance; in addition, during the liquid taking process of some systems, the liquid taking tube and the conversion cover are easily exposed to the external environment, increasing the risk of dialysis fluid being contaminated. Content of the Utility Model

[0005] The main purpose of the utility model is to improve the process of taking dialysis fluid and enhance the safety and use effect of dialysis fluid in view of the above defects and deficiencies. Based on this, a container conversion cover is provided.

[0006] To achieve the above purpose, the specific technical solution adopted by the utility model is as follows:

[0007] A container conversion cover described in the utility model includes an inner cover and an outer cover, and the outer cover can wrap the inner cover and can be detachably connected to the liquid taking port;

[0008] The inner cover includes a disk seat and a nozzle, the disk seat can be connected to the liquid taking port, the nozzle is fixedly connected to the disk seat and serves as an interface for connecting the liquid taking tube and the liquid taking port. Among them, the nozzle is made of a deformable material so that the nozzle can retract into the liquid taking port and form a sealing structure at the root.

[0009] Preferably, cutting film teeth are provided at the bottom of the disc base.

[0010] Preferably, the cutting film teeth are arranged in an incomplete circumferential structure.

[0011] Preferably, the cutting film teeth are arranged within the range of 2 / 3 of the circumference of the disc base.

[0012] Preferably, limiting holes corresponding to the limiting members of the liquid taking port are provided on the disc base.

[0013] Preferably, the limiting holes are of a structure of 4 evenly distributed single holes along the circumference.

[0014] Preferably, the nozzle is integrally formed with the disc base.

[0015] Preferably, the nozzle is arranged in a "nipple" shape.

[0016] Compared with the prior art, the utility model has the following beneficial effects:

[0017] The container conversion cover of the utility model comprises two parts: an inner cover and an outer cover. The inner cover includes a disc base and a nozzle. The nozzle is made of a deformable material and can retract into the liquid taking port and form a sealing structure at the root. The outer cover can be snap-connected with the liquid taking port and can wrap the inner cover to achieve the sealing purpose when liquid is not taken.

[0018] When taking liquid, a special liquid taking gun is used for operation. The liquid taking gun includes a liquid suction handle and a liquid taking tube. By the contact of the liquid taking tube with the nozzle, the nozzle is driven to deform downward and retract below the disc base and enter the liquid taking port. When the liquid taking tube is completely inserted, the liquid suction handle is fitted and connected with the disc base to achieve sealing and prevent the liquid taking tube and the nozzle from being exposed to the external environment.

[0019] In addition, the container conversion cover of the utility model also has other unique design features. For example, cutting film teeth are provided at the bottom of the disc base for cutting the sealing film in the initial state to facilitate opening the liquid taking port. At the same time, limiting holes are provided on the disc base and are inserted with the limiting members on the liquid taking port for fixing the disc base and preventing it from falling into the liquid taking port. These design features further improve the safety and use effect of the utility model.

[0020] Through the above improvements, the container conversion cover of the utility model can significantly improve the safety and use effect of the dialysate, reduce the risk of the dialysate being contaminated, and improve the use experience of patients.

[0039] The following further illustrates the present utility model through specific examples.

[0040] Embodiment

[0041] This embodiment provides a container conversion cap, as Figure 1 、 5 、shown in Figure 6, including a liquid-carrying barrel 10, a conversion cap 20, and a liquid-taking gun 30. A liquid-taking port 11 is provided at the top of the liquid-carrying barrel 10, and the conversion cap 20 is buckled on the liquid-taking port 11. The liquid-carrying barrel 10 is loaded with dialysis AB liquid for dialysis; the liquid-taking gun 30 can be inserted into the conversion cap 20 and enter the interior of the liquid-carrying barrel 10 through the liquid-taking port 11 to take liquid.

[0042] Specifically, a handle 12 is provided on the liquid-carrying barrel 10, and the handle 12 is used to lift and move the liquid-carrying barrel 10.

[0043] Specifically, the liquid-taking port 11 is arranged in a cylindrical shape.

[0044] Specifically, a sealing film is provided at the port of the liquid-taking port 11 in the initial state, and the sealing film is used to seal the liquid-taking port 11 to prevent external pollutants from contaminating the liquid in the barrel.

[0045] Specifically, as Figure 2 shown, the conversion cap 20 includes an inner cap 21 and an outer cap 22. The outer cap 22 can be buckled and connected with the liquid-taking port 11, and moreover, the outer cap 22 can wrap the inner cap 21. When liquid is not taken, the outer cap 22 wraps the inner cap 21 to achieve the sealing purpose and prevent the liquid in the barrel from being contaminated by the outside.

[0046] More specifically, as Figures 9 - 11 shown, the inner cap 21 includes a disc base 211 and a nozzle 212. The nozzle 212 is made of a deformable material (such as silica gel), and the nozzle 212 can retract into the liquid-taking port 11 and form a sealing structure 213 at the root;

[0047] The sealing structure 213 can minimize the leakage of the liquid in the barrel, especially for volatile liquids, which can avoid excessive volatilization and cause waste of materials; in addition, liquid volatilization will cause a change in the material concentration and affect the use effect;

[0048] It can be understood that the nozzle 212 is a nipple with the end cut off;

[0049] The nipple-shaped inner cap has an opening with a constricted top, which facilitates alignment with the pouring position when pouring the liquid in the bucket.

[0050] The disc base 211 is connected to the liquid extraction port 11, and the nozzle 212 is fixedly connected to the disc base 211.

[0051] Specifically, the nozzle 212 and the disc base 211 are integrally formed.

[0052] Such as Figure 7 、 8 As shown, the liquid extraction gun 30 includes a liquid suction handle 31 and a liquid extraction tube 32. When extracting liquid, the liquid extraction tube 32 enters the liquid extraction port 11 from the nozzle 212. When the liquid extraction tube 32 contacts the nozzle 212, it drives the nozzle 212 to deform downward, causing the nozzle 212 to retract below the disc base 211 and enter the liquid extraction port 11. When the liquid extraction tube 32 is fully inserted, the liquid suction handle 31 is fitted and connected to the disc base 211. In this way, while achieving the sealing purpose, it avoids the liquid extraction tube 32 and the nozzle 212 being exposed outside, and minimizes the pollution of the liquid in the bucket as much as possible.

[0053] More specifically, as Figure 3 、 4 As shown, the bottom of the disc base 211 is provided with film-cutting teeth 2111, and the liquid extraction port 11 is provided with a sealing film in the initial state. The film-cutting teeth 2111 are used to cut the sealing film to facilitate opening the sealing film of the liquid extraction port 11.

[0054] More specifically, the film-cutting teeth 2111 are arranged in an incomplete structure along the circumferential direction.

[0055] Specifically, the film-cutting teeth 2111 are set within a range of 2 / 3 of the circumference, and the remaining 1 / 3 of the circumference is not provided with film-cutting teeth 2111. In this way, it can prevent the sealing film from being completely cut, and prevent the sealing film from falling into the liquid extraction port 11 due to being completely cut.

[0056] In addition, the diaphragm teeth 2111 can be connected to the disc base 211 through a gasket 2113.

[0057] More specifically, the disc base 211 is provided with a limiting hole 2112, and the liquid extraction port 11 is provided with a limiting member 111 corresponding to the limiting hole 2112. The limiting member 111 is inserted into the limiting hole 2112 to fix the disc base 211, so as to prevent the disc base 211 from also entering the liquid extraction port 11 during the retraction process of the nozzle 212, that is, to keep the position of the disc base 211 unchanged and ensure the stability of the liquid extraction process.

[0058] More specifically, the limiting member 111 is set in a hook shape.

[0059] The usage method is as follows: The liquid carrier bucket 10 is transported from the outside to the ward and placed in a suitable position. At this time, to ensure sealing during transportation, the diaphragm is in a sealed state. Use the film-cutting teeth 2111 to rotate and cut the diaphragm to remove the sealing film. Then, align the limiting member 111 with the limiting hole 2112 and insert it to fix the inner cover 21 and prevent the inner cover 21 from falling into the liquid extraction port 11. Then, cover the outer cover 22 on the inner cover 21 and snap-connect it to the liquid extraction port 11.

[0060] More specifically, the limiting holes 2112 are four single-hole structures evenly distributed in the circumferential direction.

[0061] More specifically, in order to be able to cut the sealing film, the length of the film-cutting teeth 2111 needs to exceed the height of the limiting member 111.

[0062] The present utility model is described by way of examples, but does not constitute a limitation to the present utility model. Referring to the description of the present utility model, other variations of the disclosed embodiments, which are easily conceivable to those skilled in the art, should fall within the scope defined by the claims of the present utility model.
