Abstract

This utility model relates to the field of medical device technology, and discloses a loading device and a loading system. The loading device is used to accommodate valves and valve clips. The loading device includes a shell with a receiving cavity and a filter structure disposed within the shell. By setting the filter structure, the shell can be divided into a first receiving area for accommodating the valves and valve clips and a second receiving area for accommodating cooling substances.

Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to a loading device and a loading system. Background Technology

[0002] Current transcatheter aortic valve implantation (TCA) requires inserting the valve into the body using a valve clip. Before implantation, both the clamping part of the valve clip and the valve are placed inside a housing. This housing is used to hold saline solution containing ice crystals. The ice crystals ensure that the temperature of the saline solution is within the valve storage temperature range. The handle of the valve clip is placed at the opening of the housing. The saline solution containing ice crystals ensures the stability of the valve's performance before implantation and during valve clamping.

[0003] Because the valve comes into direct contact with ice fragments, the sharp tips of these ice fragments can easily damage the valve. Furthermore, when the valve clip carries ice fragments, there is a risk that the ice fragments on the clip may also damage the valve during the valve loading process. Additionally, since the valve is delivered to the patient via the clip, the clip itself may also enter the patient's body, potentially leading to ice fragments from the clip or the valve itself entering the patient's body, thus increasing the risks associated with the implantation procedure. Utility Model Content

[0004] In view of this, the present invention provides a loading device and loading system to solve the problems of valve damage caused by contact between the valve and ice slag, affecting valve performance, and ice slag easily entering the patient's body along with the valve and valve clip, leading to increased risks during implantation.

[0005] In a first aspect, this utility model provides a loading device for accommodating a valve and a valve clip, the loading device comprising:

[0006] The housing includes a receiving cavity;

[0007] A filter structure is disposed within the housing. The filter structure is used to divide the receiving cavity into a first receiving area and a second receiving area. The first receiving area is used to receive the valve and the valve clamp, and the second receiving area is used to receive a solid-liquid mixture of cooling substances. The filter structure is used to block the solid in the cooling substances to the second receiving area, while allowing the liquid in the cooling substances to pass through and enter the first receiving area.

[0008] Beneficial effects: By incorporating a filtration structure, the shell can be divided into a first containing area for the valve and valve clip, and a second containing area for the cooling substance. The filtration structure effectively blocks solids (ice shavings) from the cooling substance from reaching the second containing area, allowing only the liquid portion of the cooling substance to enter the first containing area. This cools the valve and valve clip, preventing ice shavings from contacting and damaging the valve, thus improving valve stability. Simultaneously, it prevents ice shavings from entering the body, further enhancing the stability of the implantation procedure.

[0009] In one optional embodiment, the filter structure is provided with a plurality of filter holes, through which the liquid in the cooling substance enters the first containment area;

[0010] And / or, the filter structure is detachably connected to the housing.

[0011] Beneficial effects: By setting multiple filter holes in the filter structure to achieve filtration, the filter structure material can be made of materials with good rigidity and no deformation, such as stainless steel, which can increase the reliability of the connection between the filter structure and the shell.

[0012] When the filter structure ages and becomes damaged, it is not necessary to replace the entire loading device. The filter structure can be replaced simply by disassembling it from the housing, allowing the loading device to continue to be used and achieving the technical effect of saving costs.

[0013] In one alternative embodiment, the loading device includes:

[0014] The positioning structure is fixedly connected to the receiving cavity, and the filtering structure is detachably connected to the positioning structure.

[0015] Beneficial effects: By setting a positioning structure that is slidably connected to the filtering structure, this application can achieve the technical effect of improving the ease of use of the loading device.

[0016] In one alternative implementation, the positioning structure engages with the filtering structure.

[0017] Beneficial effects: By engaging the filter structure with the positioning structure, the filter structure can be easily installed and removed by sliding into or out of the positioning structure, thereby improving the ease of installation and removal of the filter structure.

[0018] In one optional implementation, the positioning structure includes:

[0019] First positioning component;

[0020] The second positioning element is spaced apart from the first positioning element;

[0021] The filter structure is located in the gap between the first positioning member and the second positioning member.

[0022] Beneficial effects: By engaging the filter structure within the first and second positioning components, the filter structure can be easily installed and removed by sliding into or out of the positioning structure, thereby improving the ease of installation and removal of the filter structure.

[0023] In one alternative embodiment, the loading device includes:

[0024] A sealing structure is provided within the receiving cavity, and the sealing structure is detachably connected to the filter structure.

[0025] Beneficial effects: By setting up a sealed structure, the number of connection points between the filter structure and the housing can be increased, so that there is no gap between the filter structure and the housing. This avoids the possibility that solids could enter the first housing area through the gap between the filter structure and the housing and damage the valve. In other words, the sealing structure can improve the filtration reliability of the filter structure.

[0026] In one optional embodiment, the positioning structure is located at both ends of the filter structure, and the sealing structure is located below the filter structure.

[0027] Beneficial effects: The connection between the filter structure and the housing is achieved through both ends of the filter structure, and the sealing structure ensures that there are no gaps at the connection between the bottom of the filter structure and the housing, thereby improving the filtration effect.

[0028] In one optional embodiment, the housing is provided with a limiting structure, the limiting structure is in communication with the first receiving area, one end of the valve clip is placed in the first receiving area, and the other end of the valve clip is placed in the limiting structure.

[0029] Beneficial effects: The limiting structure fixes the position of the other end of the valve clip, preventing the valve clip from falling off the outside of the housing due to instability in its position, thus affecting the use of the valve clip.

[0030] In one optional implementation, the limiting structure is a limiting groove;

[0031] And / or, the loading device includes:

[0032] A telescopic structure is provided within the limiting structure to accommodate valve clips of different sizes.

[0033] Beneficial effects: The limiting groove can limit the other end of the valve clip, which can improve the structural simplicity of the limiting structure.

[0034] The telescopic structure can be matched with valve clips of different sizes, making it applicable to valve clips of various shapes, thereby improving the applicability of the loading device.

[0035] Secondly, this utility model also provides a loading system, comprising:

[0036] The loading device described above;

[0037] A container is disposed within the receiving cavity, and the container is detachably connected to the loading device.

[0038] Beneficial effects: Since the loading system includes a loading device, it has the same effect as the loading device, which will not be elaborated here. Attached Figure Description

[0049] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0050] The following is combined with Figures 1 to 3 The following describes embodiments of the present invention.

[0051] According to an embodiment of the present invention, in one aspect, a loading device is provided for accommodating a valve and a valve clip, the loading device comprising:

[0052] Housing 1, including a receiving cavity;

[0053] The filter structure 2 is disposed inside the housing 1. The filter structure 2 is used to divide the receiving cavity into a first receiving area 101 and a second receiving area 102. The first receiving area 101 is used to receive the valve and valve clamp, and the second receiving area 102 is used to receive the cooling substance mixed with solid and liquid. The filter structure 2 is used to block the solid in the cooling substance into the second receiving area 102, while allowing the liquid in the cooling substance to pass through and enter the first receiving area 101.

[0054] In the loading device of this embodiment, by setting a filter structure 2, the housing 1 can be divided into a first receiving area 101 for accommodating the valve and valve clip, and a second receiving area 102 for accommodating the cooling material. The filter structure 2 can block solids, i.e., ice slag, in the cooling material from entering the second receiving area 102, allowing only the liquid in the cooling material to enter the first receiving area 101 to cool the valve and valve clip, preventing ice slag from contacting the valve and causing damage, thereby achieving the technical effect of improving the stability of valve performance. At the same time, it prevents ice slag from entering the human body, thereby achieving the technical effect of improving the stability of the implantation procedure.

[0055] In this embodiment, the cooling substance in the solid-liquid mixture is frozen 0.9% sterile saline solution, i.e., the saline solution contains ice crystals. Of course, in other embodiments, the cooling substance in the solid-liquid mixture can also be purified water containing ice crystals, or other cooling substances.

[0056] In addition, in this embodiment, the filter structure 2 is provided with a plurality of filter holes 201. The liquid in the cooling substance enters the first receiving area 101 through the filter holes 201, while the solid in the cooling substance cannot pass through the filter holes 201.

[0057] Of course, in other embodiments, the filter structure 2 may not have filter holes 201, and the material of the filter structure 2 itself may be permeable to water. For example, the filter structure 2 may be made of medical non-woven fabric, which can still achieve the technical effect of blocking solids in the cooling substance while allowing liquids in the cooling substance to pass through. Compared with other embodiments, in this embodiment, by setting multiple filter holes 201 on the filter structure 2 to achieve filtration, the filter structure 2 can be made of a material with good rigidity, such as stainless steel, which will not deform, thereby increasing the reliability of the connection between the filter structure 2 and the shell 1.

[0058] Preferably, the filter structure 2 is detachably connected to the housing 1. Therefore, when the filter structure 2 ages and becomes damaged, it can be replaced by disassembling it from the housing 1. Of course, in other embodiments, the filter structure 2 can be fixedly connected to the housing 1, in which case the entire loading device needs to be replaced. Compared to other embodiments, this embodiment does not require replacing the entire loading device; only the filter structure 2 needs to be replaced, allowing the loading device to continue to be used, thus achieving a cost-saving effect.

[0059] Of course, in other embodiments, multiple filter holes 201 may be provided only on the filter structure 2, or the filter structure 2 may be detachably connected to the housing 1.

[0060] In addition, combined Figure 1 and Figure 2 As shown, the loading device includes:

[0061] Positioning structure 3 is fixedly connected within the receiving cavity. The filter structure 2 and the housing 1 are detachably connected via a detachable connection between the filter structure 2 and the positioning structure 3.

[0062] Specifically, the positioning structure 3 is engaged with the filter structure 2, or slidably connected to it. When the positioning structure 3 slides out of the filter structure 2, the positioning structure 3 and the filter structure 2 are disassembled; when the positioning structure 3 slides into the filter structure 2, the positioning structure 3 and the filter structure 2 are installed.

[0063] Specifically, positioning structure 3 includes:

[0064] First positioning component 301;

[0065] The second positioning element 302 is spaced apart from the first positioning element 301;

[0066] The filter structure 2 is located in the gap between the first positioning member 301 and the second positioning member 302.

[0067] The first positioning member 301 is fixedly connected to the housing 1, and both the first positioning member 301 and the second positioning member 302 are plate-shaped structures. Of course, in other embodiments, the first positioning member 301 and the second positioning member 302 can also be spherical structures.

[0068] Furthermore, the first positioning member 301, the filter structure 2, and the second positioning member 302 may each be provided with a positioning groove penetrating the first receiving area 101 and the second receiving area 102. The three positioning grooves are connected. The positioning structure 3 includes a positioning rod that passes through all three positioning grooves simultaneously, enabling the filter structure 2 to move along... Figure 2 The positioning along the Z-axis, as shown, achieves the technical effect of improving the stability of the position of the filter structure 2.

[0069] As an alternative implementation, the positioning structure 3 can also be a clamp, which is movably connected to the housing 1. The clamp fixes the filter structure 2 to the housing 1, thereby achieving a detachable connection between the filter structure 2 and the housing 1. Compared to other embodiments, in this embodiment, the filter structure 2 is snapped into the first positioning member 301 and the second positioning member 302, allowing the filter structure 2 to be installed and removed simply by sliding it into or out of the positioning structure 3, thus improving the ease of installation and removal of the filter structure 2.

[0070] As an alternative implementation, the first positioning member 301 and the housing 1, as well as the second positioning member 302 and the housing 1, can be detachably connected. Specifically, both the first positioning member 301 and the housing 1 are provided with a first threaded hole, one end of the first double-ended stud is threadedly connected to the first positioning member 301, and the other end of the first double-ended stud is threadedly connected to the housing 1. Further, both the second positioning member 302 and the housing 1 are provided with a second threaded hole, one end of the second double-ended stud is threadedly connected to the second positioning member 302, and the other end of the second double-ended stud is threadedly connected to the housing 1.

[0071] In other embodiments, the positioning structure 3 may be omitted, and the filter structure 2 may be detachably connected to the housing 1 via bolts. Compared to other embodiments, the positioning structure 3, which is slidably connected to the filter structure 2 in this application, eliminates the need for threaded connections, thereby improving the ease of use of the loading device.

[0072] Furthermore, in this embodiment, the bends of the housing 1 are rounded. This avoids sharp bends in the housing 1 that could scratch the valve, thus enhancing the protective effect on the valve.

[0073] Of course, in other embodiments, the shape of the bend in the housing 1 can be adjusted according to the different designs of the loading device, as long as the bend of the loading device does not scratch the shape of the valve, it is within the protection scope of this application.

[0074] In addition, combined Figure 1 As shown, the loading device includes:

[0075] The sealing structure 5 is located inside the receiving cavity and is detachably connected to the filter structure 2.

[0076] Based on the setting of the sealing structure 5, the connection points between the filter structure 2 and the receiving cavity can be increased, so that the filter structure 2 and the housing 1 are seamlessly connected, avoiding the gap between the filter structure 2 and the housing 1. Solids can enter the first receiving area 101 through the gap between the filter structure 2 and the housing 1 and damage the valve. That is, the sealing structure 5 can improve the filtration reliability of the filter structure 2.

[0077] In this embodiment, the sealing structure 5 has the same structure as the positioning structure 3, and the sealing structure 5 includes:

[0078] Third positioning component 501;

[0079] The fourth positioning element 502 is spaced apart from the third positioning element 501;

[0080] The filter structure 2 is located in the gap between the third positioning member 501 and the fourth positioning member 502.

[0081] Based on this, the filter structure 2 can be inserted between the third positioning member 501 and the fourth positioning member 502, so that the connection position of the filter structure 2 and the sealing structure 5 overlaps. This can increase the sealing and stability of the connection between the filter structure 2 and the housing 1. The sealing structure 5 prevents solids in the cooling material from entering the second receiving area 102 through the connection position between the filter structure 2 and the housing 1, thereby achieving the technical effect of improving the filtration reliability of the filter structure 2.

[0082] Of course, in other embodiments, the structure of the sealing structure 5 can be adjusted according to the different designs of the loading device.

[0083] In other embodiments, the sealing structure 5 may be omitted.

[0084] In addition, combined Figure 1 and Figure 2 As shown, in this embodiment, the positioning structure 3 is located at both ends of the filter structure 2 along the Y-axis, and the sealing structure 5 is located below the filter structure 2. The sealing structure 5 ensures a seamless connection between the bottom of the filter structure 2 and the housing 1, thereby improving the filtration effect.

[0085] Of course, in other embodiments, the positions of the positioning structure 3 and the filter structure 2 can be adjusted according to the different designs of the loading device. For example, the positioning structure 3 can be located at the bottom of the filter structure 2 or at both ends of the filter structure 2.

[0086] In this embodiment, the housing 1 is provided with a limiting structure, which communicates with the first receiving area 101. One end of the valve clip is placed in the first receiving area 101, and the other end of the valve clip is placed in the limiting structure. Based on this, the limiting structure fixes the position of the other end of the valve clip, preventing the valve clip from falling off to the outside of the housing 1 due to instability in its position, thus affecting the use of the valve clip.

[0087] In this embodiment, combined with Figures 1 to 3 As shown, the limiting structure is a limiting groove 103. Furthermore, the limiting groove 103 is semi-circular, which can be applied to cylindrical valve clips, thereby improving the fit between the limiting groove 103 and the valve clip, thus achieving the technical effect of improving the positional stability of the valve clip.

[0088] Of course, in other embodiments, the limiting structure can be a clip. Compared to other embodiments, in this embodiment, the limiting groove 103 can be used to limit the other end of the valve clip, which can improve the structural simplicity of the limiting structure. At the same time, no other parts are needed, thus reducing the manufacturing cost of the loading device.

[0089] In other embodiments, the shape of the limiting groove 103 can be adjusted according to the different shapes of the valve clips.

[0090] In addition, combined Figure 3 As shown, in this embodiment, the loading device includes:

[0091] The telescopic structure 4 is located within the limiting structure. The telescopic structure 4 is matched with valve clips of different sizes, so that the telescopic structure 4 can be applied to valve clips of various shapes, thereby achieving the technical effect of improving the applicability of the loading device.

[0092] Specifically, along the circumference of the limiting groove 103, the bottom of the limiting groove 103 is provided with multiple receiving grooves;

[0093] The telescopic structure 4 includes:

[0094] The elastic element 401 has one end disposed in the receiving groove;

[0095] The connector 402 is connected at one end to the other end of the elastic member 401, and the other end of the connector 402 is used to support the valve clip.

[0096] Specifically, pressure is applied to the connector 402 by the valve clamp, and the elastic member 401 deforms according to the different pressures of the valve clamp, allowing the connector 402 to conform to the shape of the valve clamp. This further enables the telescopic structure 4 to adapt to valve clamps of different shapes, thereby improving the applicability of the loading device. Simultaneously, the connector 402 increases the contact area between the elastic member 401 and the valve clamp, thereby enhancing the stability of the limiting structure in supporting the valve clamp.

[0097] In this embodiment, the elastic element 401 can be a spring, and the connecting element 402 can be a sheet-like structure. Of course, in other embodiments, the type of elastic element 401 and the shape of the connecting element 402 can be adjusted according to the design of the loading device.

[0098] As an alternative implementation, the telescopic structure 4 can also be a sponge, with one end of the sponge placed in the receiving groove and the other end of the sponge located in the first receiving area 101. The sponge itself can be compressed and rebounded, thus achieving the same technical effect of adapting to different valve clips.

[0099] Alternatively, the telescopic structure 4 can be omitted as an alternative implementation.

[0100] In the loading device of this embodiment, combined with Figure 2 As shown, the length L1 of the receiving cavity is within the range of 530mm-550mm, the width W of the receiving cavity is within the range of 180mm-200mm, and the height of the receiving cavity along the Z-axis is 100mm. Combined with... Figure 1 As shown, the second accommodating area 102 is along Figure 1 The horizontal dimension L2 shown is within the range of 40mm-45mm. (Combined with...) Figure 1 and Figure 2 As shown, the limiting groove 103 along Figure 1 The horizontal length L3 shown is within the range of 40mm-45mm, along... Figure 2 The dimension L4 in the Z-axis direction shown is within the range of 40mm-45mm.

[0101] Of course, in other embodiments, the dimensions of the receiving cavity, the second receiving area 102, and the limiting groove 103 can be adjusted according to the different designs of the loading device.

[0102] According to an embodiment of the present invention, another aspect provides a loading system, comprising:

[0103] The aforementioned loading device;

[0104] The container is located inside the receiving cavity, and the container and the loading device are detachably connected.

[0105] Since the loading system includes a loading device and has the same effect as the loading device, it will not be described in detail here.

[0106] In addition, in this embodiment, the container is provided with an open slot that communicates with the outside. The container located at the opening of the open slot is provided with an extension, which is snapped onto the housing 1 at the opening of the receiving cavity. When the container is used, the container can be separated from the housing 1.

[0107] Of course, in other embodiments, the detachable connection between the container and the shell 1 can be adjusted as needed, for example, by using a clamp. Compared to other embodiments, this embodiment achieves a detachable connection between the container and the shell 1 without the need for additional parts, thereby improving the structural simplicity of the loading system.

[0108] In addition, in this embodiment, there are four containers: three containers are used as cleaning containers for cleaning the valves, and one container is used to hold heparin, which is used to treat the valves.

[0109] Preferably, the outer surface of the container for holding heparin can be marked to distinguish it from the other three containers used for cleaning the valve, thus avoiding container confusion and affecting the safety of the implantation procedure.

[0110] Of course, in other embodiments, the number of containers can be adjusted as needed.

[0111] In the loading system of this embodiment, the container opening slot is square, and the length and width of the opening slot are both within the range of 160mm-200mm, while the height of the container is within the range of 80mm-90mm.

[0112] Alternatively, the container opening can be circular in shape, with a diameter ranging from 160mm to 200mm.

[0113] Of course, in other embodiments, the shape of the container's opening and the size of the container can be adjusted depending on the design of the loading system.

[0114] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope defined by the appended claims.
