Detailed implementation manners

[0036] To make the objectives, technical solutions and advantages of the present utility model clearer, the technical solutions of the present utility model will be clearly and completely described below in conjunction with the detailed implementation manners. The same reference numerals in the drawings represent the same components. It should be noted that the described embodiments are some embodiments of the present utility model, rather than all embodiments. All other embodiments obtained by those of ordinary skill in the art based on the described embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0037] Compared with the embodiments shown in the drawings, the feasible implementation manners within the protection scope of the present utility model may have fewer components, have other components not shown in the drawings, different components, components arranged differently, or components connected differently, etc. In addition, two or more components in the drawings may be implemented in a single component, or a single component shown in the drawings may be implemented as multiple separate components.

[0038] An embodiment of the present utility model discloses a physiological saline quantitative preparation device (hereinafter simply referred to as "preparation device" for convenience), in the hope that the preparation device can quickly and conveniently prepare a predetermined amount of physiological saline.

[0039] As Figure 1 shown, it shows a schematic structural diagram of the preparation device disclosed in the embodiment of the present utility model. In Figure 1 the shown preparation device, the preparation device may include a feeding part 10 and a container 20.

[0040] Combined with Figures 2 to 7 the content shown, the feeding part 10 may include a rotating part 11 and a connecting part 12. The rotating part 11 defines a first sealing surface 111 and a plurality of material storage cavities 112 having blanking ports 113. Refer to Figure 5 and Figure 6The material outlets 113 of the plurality of material storage chambers 112 all penetrate the first sealing surface 111 and are arranged on the same circumference with the reference axis s passing through the first sealing surface 111 as the center. The connecting portion 12 defines a second sealing surface 121 and a feed channel 122 penetrating the second sealing surface 121. Figure 3 As shown, the first sealing surface 111 of the rotating part 11 is sealed with the second sealing surface 121 of the connecting part 12 .

[0041] For example, the drawings of the present invention show a case where the rotating part 11 has three material storage cavities 112. In addition, the feed channel 122 on the connecting part 12 and the material drop opening 113 of each material storage cavity 112 can be in the form of a hole, and the diameter of the feed channel 122 on the connecting part 12 can be equal to the diameter of the material drop opening 113 of each material storage cavity 112.

[0042] like Figure 5 or Figure 6 As shown, the multiple storage chambers 112 on the rotating part 11 can have different volumes. Among them, the storage chambers 112 on the rotating part 11 are suitable for temporarily storing a certain amount of sodium chloride when preparing physiological saline. In order to facilitate the addition of sodium chloride to each storage chamber 112, each storage chamber 112 also has a discharge port 114. Among them, the discharge port 114 can be opened on the side of the rotating part 11 away from the first sealing surface 111. In addition, a removable covering portion 13 can be provided at the discharge port 114 of each storage chamber 112, so that when there is no need to add sodium chloride to the storage chamber 112, it can be opened. Figure 4 The manner shown utilizes the covering portion 13 to seal the discharge port 114 of the storage cavity 112. For example, the covering portion 13 may be a cover plate disposed at the discharge port 114 of the storage cavity 112, and a bearing step adapted to the covering plate may be disposed at the discharge port 114, so that the covering plate can seal the discharge port 114 in a manner of bearing on the bearing step; at the same time, a hand-held portion 14 such as a handle may be disposed on the covering portion 13, so that medical personnel can operate the hand-held portion 14 to remove the covering portion 13.

[0043] Further, based on the fact that the concentration of normal saline is generally 0.9%, that is, there is 0.9 g of sodium chloride in 100 ml of water (such as distilled water), and since the density of sodium chloride used to prepare normal saline is generally about 1 g / ml, the volume of 1 g of sodium chloride is approximately 1 ml; therefore, it can be considered to design the volume of each storage chamber 112 as an integer multiple of 0.9. In this way, when a single storage chamber 112 is just filled with sodium chloride, only the water corresponding to the amount of sodium chloride in the storage chamber 112 needs to be prepared, and the sodium chloride in the storage chamber 112 is transferred to the prepared water, then the predetermined amount of normal saline can be quickly prepared. For example, considering that in actual clinical work, medical staff usually have the need to prepare about 500 ml, 1000 ml or 1500 ml of normal saline. Therefore, when there are three storage chambers 112 on the rotating part 11, the volumes of the three storage chambers 112 can be set to 4.5 ml, 9 ml and 13.5 ml respectively. In this way, when it is necessary to prepare about 500 ml of normal saline, first store sodium chloride in the storage chamber 112 with a volume of 4.5 ml until the storage chamber 112 with a volume of 4.5 ml is just filled with sodium chloride, then prepare 500 ml of water, and finally transfer all the sodium chloride stored in the storage chamber 112 with a volume of 4.5 ml to the prepared 500 ml of water, then 500 ml of normal saline can be prepared. By analogy, about 1000 ml or 1500 ml of normal saline can be quickly prepared.

[0044] Among them, referring to Figure 4 as shown, identification words or identification parts (not shown in the figure) for indicating the volume of the storage chamber 112 can be provided on the covering part 13 described above, so that medical staff can intuitively observe the volume of each storage chamber 112. Among them, the identification part can be an identification card pasted on the covering part 13.

[0045] Furthermore, the rotating part 11 is also configured to be able to rotate around the reference axis s, so that the material dropping ports 113 of the plurality of storage chambers 112 can be aligned with the feeding channels 122 on the connecting part 12 in sequence. For example, combining Figure 3 and Figure 5 as shown, the rotation fit between the rotating part 11 and the connecting part 12 can be realized by providing an upwardly open rotating groove 123 on the connecting part 12 and rotatably connecting the rotating part 11 in the rotating groove 123. At this time, the inner bottom wall of the rotating groove 123 can be used as the second sealing surface 121 of the connecting part 12.

[0046] In this embodiment, combining Figure 2 and Figure 3As shown, the container 20 defines a mixing chamber 22 having a feed inlet 21. Among them, the container 20 is configured to be detachably connected to the connecting portion 12, and when the container 20 is connected to the connecting portion 12, the feed inlet 21 on the container 20 communicates with the feed channel 122 of the connecting portion 12. Among them, the container 20 may be a housing structure with a reference axis s as the central axis and an open top, so as to use the open opening at the top of the container 20 as the feed inlet 21. Among them, the container 20 and the connecting portion 12 may be connected by a threaded connection. For example, an external thread may be provided on the outer wall of the container 20 near its top, and a connecting groove 124 with an internal thread as shown in Figure 7 is provided on the connecting portion 12 away from the second sealing surface 121, and the internal thread of the connecting groove 124 is adapted to the external thread on the outer wall of the container 20.

[0047] It can be understood that based on the above settings, the preparation device can be used to quickly and conveniently prepare a predetermined amount of physiological saline. To facilitate the understanding of the preparation device disclosed in this embodiment, it is assumed that the volumes of the three storage chambers 112 on the rotating part 11 are 4.5 ml, 9 ml, and 13.5 ml respectively. Hereinafter, taking the preparation of about 500 ml of physiological saline as an example, the usage method of the preparation device disclosed in this embodiment will be described.

[0048] Specifically, when it is necessary to prepare approximately 500 ml of physiological saline, first add 500 ml of water into the mixing chamber 22 through the feed port 21 of the container 20; secondly, connect the container 20 to the connecting portion 12 of the feeding member 10 so that the feed port 21 on the container 20 communicates with the feed channel 122 on the connecting portion 12; on this basis, remove the covering portion 13 on the storage chamber 112 with a volume of 4.5 ml to expose the discharge port 114 of the storage chamber 112; then rotate the rotating portion 11 so that the discharge port 113 of the storage chamber 112 with a volume of 4.5 ml is misaligned with the feed channel 122 on the connecting portion 12, so as to use the second sealing surface 121 of the connecting portion 12 to seal the discharge port 113 of the storage chamber 112. After that, sodium chloride can be added into the storage chamber 112 until the storage chamber 112 is just filled with sodium chloride. At this time, the mass of sodium chloride in the storage chamber 112 is approximately 4.5 g; finally, rotate the rotating portion 11 again so that the discharge port 113 of the storage chamber 112 with a volume of 4.5 ml and filled with sodium chloride is aligned with the feed channel 122 of the connecting portion 12, so that the sodium chloride in the storage chamber 112 flows through the discharge port 113 of the storage chamber 112, the feed channel 122 of the connecting portion 12, and the feed port 21 of the container 20 in sequence and then enters the mixing chamber 22 of the container 20, so as to facilitate the mixing of sodium chloride and the water in the mixing chamber 22, and further realize the preparation of approximately 500 ml of physiological saline. By analogy, only by referring to the above method and selecting storage chambers 112 with different volumes to place sodium chloride, approximately 1000 ml or 1500 ml of physiological saline can be prepared quickly and conveniently.

[0049] It can be understood that after the predetermined amount of physiological saline is prepared, only by removing the container 20 from the connecting portion 12, the prepared physiological saline can be poured out and used from the feed port 21 of the container 20, and the operation is simple and convenient.

[0050] In order to facilitate the sodium chloride in the storage chamber 112 just filled with sodium chloride to smoothly enter the mixing chamber 22 of the container 20 through the feed channel 122 of the connecting portion 12, in combination with Figure 3 the content shown, the bottom of each storage chamber 112 can be funnel-shaped. At this time, the discharge port 113 is arranged at the bottommost part of the funnel-shaped storage chamber 112.

[0051] In this embodiment, the container 20 can be made of a transparent material so as to observe the situation in the mixing chamber 22 of the container 20 in real time when preparing physiological saline. For example, the container 20 can be made of transparent medical plastic or medical glass. At the same time, referring to Figure 1 the content shown, scale lines 23 matching the mixing chamber 22 can be arranged on the outer wall of the container 20, so as to quickly and accurately add a predetermined amount of water into the mixing chamber 22 of the container 20 according to the scale lines 23.

[0052] In order to enable the water and sodium chloride in the mixing chamber 22 to be mixed quickly and thoroughly, the present embodiment further improves the structure of the preparation device.

[0053] Specifically, with reference to Figure 1 and Figure 2 as shown, the preparation device may further include a stirring member 30 for stirring the water and sodium chloride in the mixing chamber 22.

[0054] Among them, the stirring member 30 may include a stirring portion 31, an operating portion 32, and a transition portion 33 connecting the stirring portion 31 and the operating portion 32. Among them, the stirring member 30 is rotatably arranged on the feeding member 10, and when the container 20 is connected to the connecting portion 12, the stirring portion 31 is located in the mixing chamber 22 of the container 20, and the operating portion 32 is located outside the mixing chamber 22. For example, the operating portion 32 may be located above the top of the rotating portion 11 of the feeding member 10, and the operating portion 32 may be an annular buckle.

[0055] Thus, in combination with the foregoing, when the container 20 filled with a predetermined amount of water is connected to the connecting portion 12, and the predetermined amount of sodium chloride enters the mixing chamber 22 of the container 20 through the corresponding storage cavity 112, the medical staff can hold the operating portion 32 of the stirring member 30 to rotate the stirring member 30. At this time, since the stirring portion 31 is located in the mixing chamber 22, rotating the stirring member 30 can cause the stirring portion 31 to continuously stir the water and sodium chloride in the mixing chamber 22, thereby enabling the water and sodium chloride in the mixing chamber 22 to be mixed quickly and thoroughly.

[0056] Among them, with reference to Figure 2 or Figure 3 as shown, the transition portion 33 can be made to pass through the connecting portion 12 and the rotating portion 11 in sequence, and the transition portion 33 can be rotationally matched with the connecting portion 12, so that the stirring member 30 can rotate relative to the feeding member 10. And the axis of the transition portion 33 can coincide with the reference axis s described above to further optimize the structural design of the preparation device.

[0057] Furthermore, as Figure 8 shown, the stirring portion 31 can include two fixing rings 311 and a plurality of stirring rods 312. The two fixing rings 311 are oppositely arranged on the transition portion 33 along the height direction of the mixing chamber 22, and the plurality of stirring rods 312 are annularly distributed along the circumference of the transition portion 33. For a single stirring rod 312, both ends of the single stirring rod 312 are respectively connected to the two fixing rings 311.

[0058] Furthermore, each stirring rod 312 has two horizontal extension segments 3121 extending along the radial direction of the mixing chamber 22 and a vertical extension segment 3122 extending along the height direction of the mixing chamber 22. Among them, the two horizontal extension segments 3121 are respectively connected to the two fixing rings 311, and the vertical extension segment 3122 is connected between the two horizontal extension segments 3121.

[0059] It can be understood that by adopting the stirring part 31 with the above structure, it is beneficial to increase the stirring area of the stirring part 31 and improve the stirring effect when stirring the water and sodium chloride in the mixing chamber 22.

[0060] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
