Description

Technical Field

[0001] The present invention belongs to the technical field of medical appliances, and particularly relates to a specimen liquid filling device. Background Art

[0002] In the operating room, some specimen fixing liquids are used, such as formalin immersion liquid, etc., for preserving, disinfecting, soaking and other treatments of tissue specimens for inspection.

[0003] Specimen fixing liquid is a toxic and harmful substance with a strong odor; some current filling methods directly pour the specimen liquid from the specimen liquid bottle body, which is easy to splash and generate a large odor.

[0004] To solve the above problems, there appears a specimen liquid extraction vehicle disclosed in CN105253850A. In order to avoid liquid leakage during liquid extraction and reduce hazards, a liquid extraction port is opened in the liquid barrel and then liquid extraction is carried out through a suction device, and the whole device is arranged in a closed cabinet, so as to further achieve the purpose of anti-leakage.

[0005] However, the specimen liquid extraction vehicle disclosed in CN105253850A still cannot well solve the leakage problem at the root during use. It only simply operates through a closed cabinet, and there is still a leakage risk when the cabinet door is opened;

[0006] At the same time, this device has more operation steps during the liquid extraction process, which is not convenient for taking and using at any time. For example, it is necessary to open and close the door and take and place multiple times. Summary of the Invention

DETAILED DESCRIPTION OF THE INVENTION

[0041] The present invention will be further described below with reference to the accompanying drawings:

[0042] As Figure 1 shown, the specimen liquid filling device includes a liquid storage mechanism 100 and a filling container 200;

[0043] The liquid storage mechanism 100 is provided with a sample output assembly 10, and the filling container 200 is provided with a sampling assembly 20;

[0044] Through the docking of the sample output assembly 10 and the sampling assembly 20, the liquid in the liquid storage mechanism 100 is then transferred to the filling container 200;

[0045] Combined with Figure 2 shown, the sample output housing 11 of the sample output assembly 10 has a through structure in the middle. The two ends of the sample output housing 11 communicate with the inner cavity of the liquid storage mechanism 100 and the outside, and the specimen liquid can pass through the sample output housing 11;

[0046] An annular sliding groove 112 is provided on the inner side wall of the sample output housing 11, and the valve plate 121 of the one-way valve 12 slides in the sliding groove 112.

[0047] Inside the cavity of the sample output housing 11, a one-way valve 12 and a seal 14 are successively arranged from inside to outside. A buffer cavity 15 is provided between the seal 14 and the one-way valve 12;

[0048] When the one-way valve 12 is opened, the specimen liquid can pass through the one-way valve 12 and reach the buffer cavity 15;

[0049] A filling needle 13 is connected to the outer side surface of the one-way valve 12. The filling needle 13 is provided with a liquid inlet 133, and the liquid inlet 133 is located in the buffer cavity 15;

[0050] A sealing structure is provided between the filling needle 13 and the seal 14, so that the buffer cavity 15 is also a quasi-sealed structure, and it can only communicate with the outside of the buffer cavity 15 through the one-way valve and the liquid inlet 133;

[0051] The filling needle 13 includes a liquid inlet portion 131 and a puncturing portion 132, and the outer diameter of the puncturing portion 132 is smaller than the inner diameter of the liquid inlet portion 131.

[0052] The liquid inlet portion 131 is connected to the one-way valve 12, and the puncturing portion 132 is located outside the seal 14.

[0053] One end of the filling needle 13 passes through the seal 14 and reaches the outside of the buffer cavity 15, and the end of the filling needle 13 reaching the outside of the buffer cavity 15 can be docked with the sampling assembly 20;

[0054] As Figure 3 、 4 described, the filling needle 13 can move in a sealed manner relative to the seal 14, and the valve plate 121 is driven to move left and right in the sliding groove 112 during the movement of the filling needle 13;

[0055] A rubber cover 20 is provided at the sample inlet of the filling container 200. The rubber cover 20 can be punctured by the puncturing portion 132, but cannot be penetrated by the liquid inlet portion 131;

[0056] Combined with Figure 6 the content shown in, a plurality of liquid guide grooves 111 are provided on the side wall of the sample output housing 11. Both ends of the liquid guide grooves 111 are respectively communicated with the inner cavity of the liquid storage mechanism 100 and the sliding groove 112;

[0057] The port of the liquid guide groove 111 communicating with the sliding groove 112 is a groove body port 1110, and the groove body port 1110 is located on one side of the sliding groove 112 close to the outer side wall 1122 of the sliding groove.

[0058] The liquid guiding groove 111 is a “U”-shaped structure, so that the liquid can reach the buffer cavity 15 from the inner cavity of the storage via the liquid guiding groove 111 .

[0059] The end of the liquid inlet portion 131 connected to the puncture portion 132 is provided with an abutment member 1310. When the puncture portion 132 passes through the rubber cover, the abutment member 1310 abuts against the rubber cover. Figure 4 When the puncture is completed, the rubber cover body continues to push the filling needle 13 to move to the left. At this time, the valve plate 121 is pushed to the left to reach the position as shown in FIG. Figure 4 Middle position,

[0060] The width of the sliding groove 112 is greater than the thickness of the valve plate 121;

[0061] The thickness of the valve plate 121 is greater than the outer diameter of the slot port 1110, and the side edge of the valve plate 121 can block the slot port 1110. Figure 3 When the valve plate 121 is located at the outer end of the sliding groove 112, the side of the valve plate 121 blocks the groove body port 1110 to achieve sealing;

[0062] The side abutment sealing of the valve plate 121 can achieve a better sealing effect.

[0063] An elastic member 122 is disposed between the valve plate 121 and the inner side wall 1121 of the sliding groove 112;

[0064] When the valve plate 121 is away from the slot port 1110 , the elastic member 122 is deformed, and the elastic member 122 has a tendency to make the valve plate 121 block the slot port 1110 .

[0065] The sample outlet assembly 10 is located at the bottom of the liquid storage mechanism 100 , and after the one-way valve 12 is opened, the sample liquid can flow out better.

[0066] A working mode of the present invention is:

[0067] Combination Figure 3 , 4 As shown in the figure, the rubber cover of the sampling assembly 20 is punctured by the puncture portion 132. At this time, the end of the puncture portion 132 enters the liquid collection bag, and the rubber cover abuts against the abutment portion 1310, pushing the filling needle 13 inward, and the filling needle 13 pushes the valve plate 121 to move inward;

[0068] The elastic member 122 is compressed, and the valve plate moves toward the inside of the sliding groove 112, staggered from the groove body port 1110, and the liquid guide groove 111 forms a passage;

[0069] At this time, if Figure 5 , 6As described, the specimen liquid in the inner cavity of the storage mechanism flows through the liquid guide groove 111, then flows out from the groove body port 1110, reaches the buffer cavity 15 on the right side of the valve piece 121, then enters the liquid inlet part 131 of the needle body from the liquid inlet 133, flows through the inner cavity of the puncture part 132, and finally passes through the rubber cover body to reach the liquid collection bag;

[0070] After the filling is completed, under the action of the elastic component 122, the valve plate 121 is moved outward to the outside of the sliding groove 112, and the valve piece 121 corresponds to the groove body port 1110, so as to block the groove body port 1110; Since the valve piece 121 has rigidity, when the hydraulic pressure in the liquid guide groove 111 is too high, the valve piece 121 can also better perform the blocking operation.

[0071] Those skilled in the art can clearly understand that various modifications to the above embodiments can be made without departing from the general spirit and concept of the present invention. All of them fall within the protection scope of the present invention. The protection scope of the present invention shall be subject to the claims attached to the present invention.
