Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a bovine pericardium chemical treatment reaction container. Background Art

[0002] With the development of modern medicine, bovine pericardium is widely used in the medical field. For example, bovine pericardium can be used as an artificial pericardium in heart transplant surgery. During the transplant process, the original pericardium may be removed or damaged, so a substitute is needed to protect the heart and maintain its shape. Before use, it must be ensured that it is sterile and has been properly processed and disinfected. This treatment can ensure the safety of the bovine pericardium during use. During the treatment process, the device for fixing the bovine pericardium is placed in a reaction box. In order to avoid the position of the device for fixing the bovine pericardium being offset in the reaction box, it is very necessary to provide a bovine pericardium chemical treatment reaction container that can fix the position of the device for fixing the bovine pericardium.

[0003] However, one of the shortcomings of the related technology is that the sample fixing bracket is not fixed, and the bracket is easily displaced during the treatment process, resulting in poor chemical treatment effect of the bovine pericardium. Utility Model Content

[0004] The utility model aims to solve at least one of the above technical problems.

[0005] In order to solve the above problems, the first purpose of the utility model is to provide a bovine pericardium chemical treatment reaction container.

[0006] To achieve the first purpose of the utility model, an embodiment of the utility model provides a bovine pericardium chemical treatment reaction container, which includes: a reaction box; a sample fixing bracket, the reaction box and the sample fixing bracket are connected by a snap assembly, the snap assembly includes: a locking block, the locking block is arranged at the bottom of the reaction box; a locking groove, the locking groove is arranged at the bottom of the sample fixing bracket, the locking block and the locking groove cooperate with each other.

[0007] The snap-on design allows the user to quickly and accurately assemble or separate the sample holder from the reaction box without the use of tools, thus improving work efficiency. The combination of the snap-on block and the snap-on slot ensures that the sample holder remains stable during the reaction, preventing accidental detachment due to vibration or impact, thereby protecting the sample from damage. The snap-on assembly can usually withstand multiple insertions and removals without damage, which makes the reaction vessel reusable and maintains good stability each time it is assembled. The snap-on connection method does not require complex mechanical structures or additional fastening elements, which helps reduce production costs and simplifies the maintenance process. Since the components can be easily separated, cleaning and maintenance work become more convenient, which helps to keep the experimental environment clean and the reaction vessel in long-term use. The use of snap-on assemblies reduces human errors that may be caused by manual tightening of screws, thereby improving the accuracy and repeatability of the experiment.

[0008] In the above technical solution, the sample fixing bracket includes a base, and the locking groove is located at the edge of the base.

[0009] The design of the snap-in slot at the edge of the base helps ensure a tighter and more stable connection between the sample holder and the reaction box. This layout takes advantage of the structural characteristics of the base, so that the snap connection bears more uniform force, reducing the risk of damage caused by uneven force. In addition, the stable connection also helps prevent the sample from moving or vibrating during the reaction process, thereby ensuring the accuracy and repeatability of the experiment. In addition, this design avoids the need for traditional fastening methods such as screws and nuts, which not only saves costs, but also makes the installation and removal process of the sample holder faster and simpler. Setting the snap-in slot at the edge of the base can also help save space, because the bracket designed in this way does not need to take up additional space inside the reaction box to accommodate the fastening components.

[0010] In any of the above technical solutions, the locking block includes a first locking boss, and the first locking boss abuts against the top of the base.

[0011] By the abutment of the first positioning boss against the top of the base, it can be ensured that the positioning block is firmly fixed to the bottom of the reaction box, thereby improving the connection firmness between the reaction box and the sample fixing bracket. This can effectively prevent the positioning block from loosening or falling off during use, ensure the safety and stability during the reaction process, and thus improve the accuracy and repeatability of the reaction. The abutment of the first positioning boss against the top of the base can provide a stable support in structure, preventing the sample fixing bracket from shifting or tilting during the reaction process. This design ensures that the reaction box and the sample fixing bracket can be closely matched, thereby ensuring the stability of the experimental process. In addition, the setting of the first positioning boss can prevent the sample fixing bracket from moving up and down, thereby preventing it from causing poor bovine pericardium processing effect due to bumps.

[0012] In any of the above technical solutions, the locking block includes a second locking boss, and the second locking boss abuts against the edge of the base.

[0013] The close fit between the second positioning boss and the edge of the base prevents the sample holder from shifting or tilting during the reaction, thereby ensuring the stability of the sample. This design ensures a more stable connection between the reaction box and the sample holder, avoids accidental detachment due to vibration or impact, and helps protect the sample from damage. This design allows the operator to quickly and accurately assemble or separate the sample holder from the reaction box without the use of tools, which improves work efficiency and simplifies the operation process.

[0014] In any of the above technical solutions, the reaction box includes at least two positioning blocks located at two ends of the bottom of the reaction box.

[0015] The blocking blocks at both ends can provide a more balanced support force, ensuring that the sample fixing bracket is more firmly connected to the reaction box. This symmetrical setting helps to disperse the force and reduce deformation or damage caused by the center of gravity offset or excessive local force. The two blocking blocks make the assembly positioning of the sample fixing bracket more precise. When installing the bracket, the blocking blocks at both ends work together to limit the position of the bracket, thereby avoiding assembly deviation and ensuring consistency in each assembly. The two blocking blocks can better withstand and disperse the force from all directions and reduce the pressure concentration caused by a single force point.

[0016] In any of the above technical solutions, the sample fixing bracket includes at least the same number of locking grooves as the locking blocks, and the locking grooves are located at both ends of the base.

[0017] The card slots corresponding to the number and position of the card blocks enable the card blocks to be accurately docked into the card slots during assembly. This design simplifies the process of correct installation and avoids assembly errors such as inversion or offset, thereby improving the accuracy of operation. The card slots distributed at both ends cooperate with the card blocks to provide balanced support and stable connection, preventing the device from shaking or tilting due to uneven force, which is crucial for accurately controlling experimental conditions and ensuring that the sample is not disturbed. Distributing the force evenly to multiple card points can reduce excessive pressure on any one point, thereby reducing the risk of component breakage and extending the service life of the entire reaction vessel.

[0018] In any of the above technical solutions, the reaction box is provided with a limit block, and the limit block abuts against an end of the sample fixing bracket away from the locking groove.

[0019] The stopper provides additional support points, working together with the stopper and the stopper slot to form a more stable fixing system. This helps prevent the sample holder from shifting or shaking during the reaction, ensuring the stability of the sample. The operator does not need to fine-tune the position of the sample holder, just make sure it is in contact with the stopper. This design simplifies the operation process and makes assembly more intuitive and easy. By limiting the range of movement of the sample holder, the stopper helps ensure that all samples are reacted in the same position, improving the standardization and repeatability of the experiment.

[0020] In any of the above technical solutions, the reaction box is provided with at least two limit blocks, and the limit blocks are located at two ends of the bottom of the reaction box.

[0021] Setting two or more limit blocks can provide more balanced and stable support, effectively preventing the sample holder from shifting or tilting during the reaction process, which is crucial to ensuring the consistency and reliability of the experiment. Multiple limit blocks can better control the position of the sample holder, making the assembly process more accurate, reducing operating errors, and thus ensuring the accuracy of the experimental results. Multiple limit blocks jointly assume the supporting role, which helps to extend the service life of the reaction box and the sample holder, especially when the sample is reused or frequently replaced. By setting limit blocks at both ends of the bottom, it can promote uniform stress distribution, avoid excessive local pressure concentration, and reduce wear and damage caused by gravity or external forces.

[0022] In any of the above technical solutions, the reaction box is provided with a liquid inlet and a liquid outlet. The liquid inlet is located at one end of the side wall of the reaction box close to the top, and the liquid outlet is located at the bottom of the reaction box.

[0023] The high-position liquid inlet facilitates the smooth entry of liquid into the reaction box, using gravity without the need for additional pressure equipment. At the same time, the liquid outlet is located at the bottom to ensure that the liquid or waste after the reaction can flow out naturally by gravity, simplifying the drainage step. Liquid enters from the top and exits from the bottom. This design conforms to the natural flow direction of the fluid, which helps to achieve a more efficient mixing and reaction process.

[0024] In any of the above technical solutions, the reaction box is provided with an air inlet and an air outlet, and the air inlet and the air outlet are arranged at one end of the side wall of the reaction box close to the top.

[0025] Centralized management of gas in and out helps control the atmosphere in the reaction chamber, for example, to facilitate replacement and maintenance of a specific gas environment during aerobic or anaerobic reactions. In some chemical reactions, the gas needs to be fully contacted and mixed with the liquid. The location of the inlet and outlet facilitates effective gas circulation and distribution, thereby enhancing the efficiency and uniformity of the reaction. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] Refer to the following Figures 1 to 5 The technical solutions of some embodiments of the utility model are described.

[0036] like Figure 1 , Figure 2The utility model shown provides an embodiment of a bovine pericardium chemical treatment reaction container, which includes: a reaction box 100; a sample fixing bracket 200, the reaction box 100 and the sample fixing bracket 200 are connected by a snap assembly, the snap assembly includes: a locking block 310, the locking block 310 is arranged at the bottom of the reaction box 100; a locking groove 320, the locking groove 320 is arranged at the bottom of the sample fixing bracket 200, and the locking block 310 and the locking groove 320 cooperate with each other.

[0037] In this embodiment, the sample fixing bracket 200 is placed at the bottom of the reaction box 100, and the positioning block 310 is sunk into the positioning groove 320. The positioning block 310 contacts the sample fixing bracket 200 and limits the position of the sample fixing bracket 200. The positioning block 310 is made of a material with a certain elasticity. When installing the sample fixing bracket 200 into the reaction box 100, the operator can use a certain force to break the positioning block 310 outward, and then insert the positioning block 310 into the positioning groove 320 and install it. After the installation is completed, the positioning block 310 is released, and the positioning block 310 will rebound to the original position to fix the sample fixing bracket 200.

[0038] like Figure 2 , Figure 3 as well as Figure 4 As shown, the sample fixing bracket 200 includes a base 210, and the locking groove 320 is located at the edge of the base 210; the locking block 310 includes a first locking boss 311, and the first locking boss 311 abuts against the top of the base 210; the locking block 310 includes a second locking boss 312, and the second locking boss 312 abuts against the edge of the base 210.

[0039] In this embodiment, the first positioning boss 311 and the second positioning boss 312 are connected together to form a positioning block 310. The height of the second positioning boss 312 is slightly higher than the thickness of the base 210. The first positioning boss 311 extends inward and has a certain protrusion. The protrusion, the second positioning boss 312 and the bottom of the reaction box 100 together form a groove, and the edge of the base 210 just fits into the groove.

[0041] In this embodiment, two blocking blocks 310 are provided at the front and rear ends of the bottom of the reaction box 100, and the two blocking blocks 310 are opposite to each other and face inward. Two blocking grooves 320 are provided at the front and rear ends of the sample fixing bracket 200. This setting can restrict the sample fixing bracket 200 from the front and rear ends to prevent one end of the sample fixing bracket 200 from moving up and down. In addition, the distance between the two blocking blocks 310 is consistent with the distance between the two blocking grooves 320. This setting can restrict the sample fixing bracket 200 to its middle part to prevent the sample fixing bracket 200 from moving forward and backward.

[0043] In this embodiment, the reaction box 100 is provided with two limit blocks 110, which are respectively arranged at the left and right ends of the bottom of the reaction box 100. The distance between the two limit blocks 110 is consistent with the width of the sample fixing bracket 200. The two limit blocks 110 are respectively abutted against the left and right ends of the sample fixing bracket 200, thereby limiting the left and right movement of the sample fixing bracket 200.
