Abstract
Description
Aseptic pinching device and its operation method Technical Field
[0001] This application relates to a clamping device and its operating method, and more particularly to a sterile clamping device and its operating method comprising two identical half-elements, one of which can be rotated 180 degrees relative to the other to engage in a locking mechanism. Background Technology
[0002] Generally, cannulas used in medical settings or laboratories require sterility. When a cannula needs to be cut, a sterile clamping and cutting device is required. Therefore, traditional clamping and cutting devices fix the cannula in a male and a female component, clamping the cannula between the two components before using a cutting tool to cut it. However, existing clamping and cutting devices require different male and female components to clamp and fix the cannula. This necessitates manufacturers producing two separate molds for the male and female components, increasing manufacturing costs and adding inconvenience for users when connecting the male and female components. Summary of the Invention
[0003] The main objective of this application is to provide a sterile clamping device and its operating method, aiming to reduce the manufacturing cost of production components and improve the convenience for users when docking two identical half-components. The sterile clamping device of this application has two half-components with identical shapes and outlines, and one of the two half-components can be rotated 180 degrees relative to the other to mate and snap together.
[0004] According to one embodiment of this application, a sterile clamping device includes two half-elements. Each half-element has a base structure, a first snap-fit structure connecting a first side of the base structure, and a second snap-fit structure connecting a second side of the base structure opposite to the first side. The two half-elements have identical shapes and profiles, and one of the two half-elements is rotated 180 degrees relative to the other half, such that one half-element and the other half-element approach each other to engage and snap. The base structures of one half-element and the other half-element form a diagonal space, which is used to accommodate a sleeve for clamping the sleeve through the two half-elements.
[0005] According to one embodiment of this application, when one of the two half-elements is rotated 180 degrees relative to the other of the two half-elements to face each other, one of the two half-elements aligns with the other of the two half-elements in the vertical direction.
[0006] According to one embodiment of this application, the first snap-fit structure of the above-mentioned semi-element has a first snap-fit body and a snap-fit end member disposed on the first snap-fit body, the snap-fit end member extending outward from the first snap-fit body.
[0007] According to one embodiment of this application, the first snap-fit body of the first snap-fit structure of the above-mentioned semi-element has an L-shaped outline, and the first snap-fit body of the first snap-fit structure faces away from the base structure.
[0008] According to one embodiment of this application, the second snap-fit structure of the above-mentioned half element has a second snap-fit body and a snap-fit groove disposed on the second snap-fit body. The snap-fit groove of one of the two half elements is used to accommodate the snap-fit end piece of the other half element to position the two half elements.
[0009] According to one embodiment of this application, the second snap-fit body of the second snap-fit structure of the above-mentioned half-element has an L-shaped profile, and the second snap-fit body of the second snap-fit structure faces the base structure.
[0010] According to one embodiment of this application, the second snap-fit body of the second snap-fit structure of the above-mentioned half-element has a connection space between it and the base structure. The connection space of one of the two half-elements is used to accommodate the first snap-fit body of the other half-element to position the two half-elements.
[0011] According to one embodiment of this application, the first snap-fit structure of the above-mentioned half element further has a connecting groove facing away from the snap-fit end member, and the second snap-fit structure of the half element further has a connecting member facing the snap-fit groove, wherein the connecting groove of one of the two half elements is used to accommodate the connecting member of the other half element to position the two half elements.
[0012] The method of using the aseptic clamping device of this application involves two half-components with identical shapes and outlines, one of which can be rotated 180 degrees relative to the other to match and snap together, thereby reducing the manufacturing cost of the components and improving the convenience for users when using two identical half-components to dock.
[0013] According to one embodiment of this application, a method of using a sterile clamping device includes: providing two half-elements, wherein the two half-elements have a base structure, a first snap-fit structure disposed on a first side of the base structure, and a second snap-fit structure disposed on a second side of the base structure relative to the first side, and the two half-elements have identical shape contours; and one of the two half-elements is rotated 180 degrees relative to the other of the two half-elements and moved closer to each other, such that one of the two half-elements is paired and snapped with the other of the two half-elements, wherein the base structure of one of the two half-elements faces the base structure of the other of the two half-elements to form a diagonal space, the diagonal space being used to accommodate a sleeve for clamping the sleeve by the two half-elements.
[0014] According to one embodiment of this application, when one of the two half-elements is rotated 180 degrees relative to the other of the two half-elements to face each other, one of the two half-elements aligns with the other of the two half-elements in the vertical direction.
[0015] According to the above embodiments of this application, the aseptic clamping device includes two half-elements with identical shapes and outlines. One of the two half-elements can be rotated 180 degrees relative to the other half, allowing the two half-elements to approach each other for mating and locking. The two base structures of the two half-elements form a diagonal space, thereby fixing the sleeve in the diagonal space. It is worth noting that the aseptic clamping device does not require the use of different male and female components as in traditional clamping devices; instead, it can clamp the sleeve in the diagonal space using only two identical half-elements. In this way, the aseptic clamping device using two identical half-elements reduces the manufacturing cost of the components and improves the convenience for users when mating two identical half-elements.

[0029] Please refer to Figures 1 to 3. Figure 1 shows a perspective view of a sterile pinching device 100 according to an embodiment of this application, Figure 2 shows a side view of the sterile pinching device 100 of Figure 1, and Figure 3 shows a perspective view of a half-element 110 according to an embodiment of this application. In Figures 1 to 3, the sterile pinching device 100 includes two half-elements 110. Each half-element 110 has a base structure 112, a first snap-fit structure 114 connecting a first side of the base structure 112, and a second snap-fit structure 116 connecting a second side of the base structure 112 opposite to the first side. For example, the first snap-fit structure 114 and the second snap-fit structure 116 of the half-element 110 are located on opposite sides of the base structure 112. In some embodiments, the number of half-elements 110 of the sterile pinching device 100 is an even number, and the number of even-numbered half-elements 110 is not limited to this.
[0030] It is worth noting that the two half-elements 110 have identical shapes and outlines. That is, the aseptic clamping device 100 is actually composed of only two half-elements 110. Furthermore, one of the two half-elements 110 can be rotated 180 degrees relative to the other half, allowing them to approach each other for mating and locking. In some embodiments, the base structure 112 of one half-element 110 and the base structure 112 of the other half-element 110 can form a diagonal space A; that is, the diagonal space A is formed by the two base structures 112 of the two half-elements 110. The diagonal space A of the two half-elements 110 can accommodate a sleeve 200 (described in detail in FIG. 8) for clamping the sleeve 200 by the two half-elements 110.
[0031] In some embodiments, the first snap-fit structure 114 of the half-element 110 has a first snap-fit body 1142 and a snap-fit end piece 1144 disposed on the first snap-fit body 1142, the snap-fit end piece 1144 of the first snap-fit structure 114 of the half-element 110 extending outward from the first snap-fit body 1142. Furthermore, the second snap-fit structure 116 of the half-element 110 has a second snap-fit body 1162 and a snap-fit groove 1164 disposed on the second snap-fit body 1162. Specifically, the snap-fit groove 1164 of the second snap-fit structure 116 of one of the two half-element 110s can accommodate the snap-fit end piece 1144 of the first snap-fit structure 114 of the other half-element 110 to snap and position the two half-element 110s, as shown in FIG1.
[0032] In some embodiments, the first snap-fit body 1142 of the first snap-fit structure 114 of the half-element 110 has an L-shaped profile, and the first snap-fit body 1142 of the first snap-fit structure 114 of the half-element 110 faces away from the base structure 112 of the half-element 110. Furthermore, the second snap-fit body 1162 of the second snap-fit structure 116 of the half-element 110 also has an L-shaped profile, and the second snap-fit body 1162 of the second snap-fit structure 116 of the half-element 110 faces the base structure 112 of the half-element 110.
[0033] Please refer to Figures 4 to 6. Figure 4 shows a top view of the half-element 110 of Figure 3, Figure 5 shows a cross-sectional view of the half-element 110 of Figure 4 along line segment AA, and Figure 6 shows a perspective view of two half-element 110s in parallel abutting according to an embodiment of this application. In Figures 4 to 6, the base structure 112 of the half-element 110 further has a protruding end 115, which is used to contact the sleeve 200 (to be described in detail in Figure 8). In addition, the opposite ends of the half-element 110 each have an abutting end 111 and an abutting groove 113. Two horizontally arranged half-element 110s can abut against each other through their respective abutting ends 111 and abutting grooves 113, so that multiple half-element 110s can be connected to each other through the abutting ends 111 and abutting grooves 113.
[0034] In some embodiments, a connection space B is provided between the second snap-fit body 1162 of the second snap-fit structure 116 of the half-element 110 and the base structure 112. The connection space B of one of the two half-element 110 is used to accommodate the first snap-fit body 1142 of the other half-element 110 to position the two half-element 110. In addition, the first snap-fit structure 114 of the half-element 110 further has a connection groove 1146 facing away from the snap-fit end member 1144, and the second snap-fit structure 116 of the half-element 110 further has a connector 1166 facing the snap-fit groove 1164. The connection groove 1146 of one of the two half-element 110 is used to accommodate the connector 1166 of the other half-element 110 to position the two half-element 110.
[0035] The following description will explain how to operate the aseptic gripping device. The connections, materials, and functions of the components already described will not be repeated, but will be stated in advance.
[0036] Please refer to Figure 7, which illustrates a flowchart of the operation method of the aseptic clamping device according to an embodiment of this application. The operation method of the aseptic clamping device includes the following steps. First, in step S1, two half-elements are provided, wherein the two half-elements have a base structure, a first snap-fit structure disposed on a first side of the base structure, and a second snap-fit structure disposed on a second side of the base structure opposite to the first side, and the two half-elements have identical shape contours. Next, in step S2, one of the two half-elements is rotated 180 degrees relative to the other of the two half-elements and brought closer to each other, such that one of the two half-elements and the other of the two half-elements are paired and snapped together, wherein the base structure of one of the two half-elements faces the base structure of the other of the two half-elements to form a diagonal space, the diagonal space being used to accommodate a sleeve for clamping the sleeve through the two half-elements. The above steps will be described in detail in the following description.
[0037] Please refer to Figures 8 to 10. Figures 8 and 9 illustrate schematic diagrams of the aseptic clamping device 100 in use according to some embodiments of this application, and Figure 10 illustrates a schematic diagram of the aseptic clamping device 100 in use according to another embodiment of this application. In Figures 8 and 9, firstly, two half-elements 110 are provided, each half-element 110 having a base structure 112, a first snap-fit structure 114 disposed on a first side of the base structure 112, and a second snap-fit structure 116 disposed on a second side of the base structure 112 opposite to the first side, and the two half-elements 110 have identical shapes and outlines. Next, a sleeve 200 for a medical environment or laboratory is provided. Then, one of the two half-elements 110 can be rotated 180 degrees relative to the other half-elements 110 and brought closer to each other, such that one of the two half-elements 110 mates and snaps with the other half-elements 110. In detail, when one of the two half-elements 110 is rotated 180 degrees relative to the other half-elements 110 to face each other, the one half-elements 110 aligns with the other half-elements 110 in the vertical direction V. Furthermore, the base structure 112 of one half-elements 110 faces the base structure 112 of the other half-elements 110 to form a diagonal space A, which accommodates the sleeve 200 to clamp the sleeve 200 through the two half-elements 110. In FIG10, the embodiment shown in FIG10 differs from the embodiment shown in FIG9 in that the aseptic clamping device 100 of FIG10 has four half-elements 110, and the four half-elements 110 are arranged horizontally side by side in pairs, so that the four half-elements 110 simultaneously clamp the sleeve 200 to improve the positioning stability between the half-elements 110 and the sleeve 200, and the sleeve 200 is cut using a cutting element. Furthermore, the first pair of half-elements 110 (i.e., the two half-elements 110 on the left side) and the second pair of half-elements 110 (i.e., the two half-elements 110 on the right side) of the aseptic clamping device 100 shown in Figure 10 can clamp the opposite ends of the sleeve 200. After the sleeve 200 is cut, the first pair of half-elements 110 can clamp the left end of the sleeve 200, while the second pair of half-elements 110 can clamp the right end of the sleeve 200, so that the opposite ends of the sleeve 200 after being cut can still remain sterile.
[0038] In summary, the aseptic clamping device 100 includes two identical half-elements 110. One of the two half-elements 110 can be rotated 180 degrees relative to the other, allowing them to approach each other for mating and locking. Furthermore, the two base structures 112 of the two half-elements 110 form a diagonal space A, thereby securing the sleeve 200 within it. It is worth noting that the aseptic clamping device 100 does not require the use of different male and female components as in conventional clamping devices; instead, it can clamp the sleeve 200 within the diagonal space A using only two identical half-elements 110. This reduces manufacturing costs and improves user convenience when using the two identical half-elements 110.
