Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a built-in hemolytic agent bottle and a blood cell analyzer. Background Technology

[0002] Hematology analyzers, as key equipment in clinical testing, are widely used in routine blood tests. By quantitatively analyzing parameters such as red blood cells, white blood cells, and platelets, they provide a basis for the diagnosis of anemia, infectious diseases, and hematological disorders. Among these, the hemolytic agent, as a core reagent, is used to lyse red blood cells and release hemoglobin; its precise delivery and stable storage directly affect the reliability of the test results. Currently, the configuration of the solvent bottles and the design of the tubing within the hematology analyzer are important factors affecting the ease of operation and safety of the equipment.

[0003] Currently, the solvent bottle configurations of blood cell analyzers on the market are mainly divided into two types: external and internal. Internal configurations are commonly found in three-part differential analyzers and some low-end five-part differential analyzers. The reagent bottles are placed inside the instrument compartment and need to be secured to the tubing via a screw-on cap or plug-in mechanism. With these internal configurations, changing reagent bottles requires unscrewing the cap, which can easily lead to tubing bending and fluid circuit blockage. In severe cases, abnormal pressure can cause tubing to burst. Utility Model Content

[0004] The main purpose of this invention is to propose a built-in hemolytic agent bottle and a blood cell analyzer, which aims to solve the problem that the tubing of existing built-in hemolytic agent bottles is prone to bending when the cap is tightened.

[0005] To achieve the above objectives, the present invention proposes a built-in hemolytic agent bottle, which includes:

[0006] A solvent bottle includes a bottle body and a bottle cap that are connected to each other, the bottle body and the bottle cap being detachably connected, and the bottle cap having an opening on the side away from the bottle body;

[0007] A movable connector block is movably disposed at the movable opening, with a gap between the movable connector block and the movable opening, and the movable connector block has a mounting hole extending through it along its thickness direction; and

[0008] A piping assembly is fixed at the mounting hole, with one end of the piping assembly extending into the interior of the bottle body and the other end of the piping assembly passing through the mounting hole and communicating with an external liquid system.

[0009] In one embodiment, the outer periphery of the movable connector block is provided with a limiting step, and the edge of the movable opening facing the inside of the bottle body abuts against the limiting step.

[0010] In one embodiment, the movable connector block includes an upper movable portion and a lower movable portion fixedly connected to the upper movable portion. The mounting hole is provided through the upper movable portion and the lower movable portion, and the outer diameter of the lower movable portion is larger than the outer diameter of the upper movable portion to form the limiting step.

[0011] In one embodiment, the outer diameter of the upper movable part is smaller than the diameter of the movable opening, the outer diameter of the lower movable part is larger than the diameter of the movable opening, and the outer diameter of the lower movable part is smaller than the inner diameter of the bottle cap.

[0012] In one embodiment, the piping assembly includes an upper liquid pipe and a lower liquid pipe, which are respectively installed on the upper movable part and the lower movable part.

[0013] In one embodiment, the piping assembly further includes a sinker mounted at the bottom of the downpipe and positioned close to the bottom of the bottle.

[0014] In one embodiment, the built-in hemolytic agent bottle further includes a sleeve, which is installed at the mounting hole, and both ends of the sleeve extend out of the mounting hole to connect the upper liquid tube and the lower liquid tube, respectively.

[0015] In one embodiment, the sleeve is threaded or bonded to the mounting hole.

[0016] In one embodiment, the outer periphery of the sleeve is provided with a positioning protrusion, and the wall of the mounting hole is provided with a positioning step, wherein the positioning protrusion and the positioning step are abutted together.

[0017] In one embodiment, the movable connector block is provided with a vent hole that connects the inside and outside of the bottle cap.

[0018] This utility model also proposes a blood cell analyzer, the blood cell analyzer comprising:

[0019] The main body of the instrument has an internal cavity.

[0020] The built-in hemolytic agent bottle, as described in any of the above embodiments, is disposed within the cavity.

[0021] The technical solution of this utility model involves setting a movable connector block on the bottle cap. The movable connector block is fixedly connected to the tubing assembly and forms a gap with the movable opening, allowing the tubing assembly to move around the movable opening along with the movable connector block. When changing the solvent bottle and tightening the cap, due to the movable nature of the connector block and the gap with the movable opening, the tubing assembly is not subjected to the torque and bending force generated by tightening the cap, thus avoiding the transmission of torque to the tubing assembly and preventing it from bending. In this solution, the tubing assembly is relatively stably fixed at the mounting hole of the movable connector block, and the adaptive movement of the connector block protects the tubing assembly. At the same time, the mounting hole in the thickness direction of the movable connector block also provides a relatively stable fixed position for the tubing assembly, preventing it from being pulled and bent during the tightening of the cap.

[0037] Currently, the solvent bottle configurations of blood cell analyzers on the market are mainly divided into two types: external and internal. Internal configurations are commonly found in three-part differential analyzers and some low-end five-part differential analyzers. The reagent bottles are placed inside the instrument compartment and need to be secured to the tubing via a screw-on cap or plug-in mechanism. With these internal configurations, changing reagent bottles requires unscrewing the cap, which can easily lead to tubing bending and fluid circuit blockage. In severe cases, abnormal pressure can cause tubing to burst.

[0038] This utility model proposes a built-in hemolytic agent bottle.

[0039] Please see Figures 1 to 3 In one embodiment of this utility model, the built-in hemolytic agent bottle 100 includes:

[0040] Solvent bottle 1 includes a bottle body 11 and a bottle cap 12 that are connected to each other. The bottle body 11 and the bottle cap 12 are detachably connected. The bottle cap 12 has an opening 121 on the side away from the bottle body 11.

[0041] The movable connector block 2 is movably disposed in the movable opening 121, with a gap between the movable connector block 2 and the movable opening 121, and the movable connector block 2 has a mounting hole 211 that extends through it along its thickness direction; and

[0042] Piping assembly 3 is fixed at mounting hole 211, with one end of piping assembly 3 extending into the interior of bottle body 11 and the other end of piping assembly 3 passing through mounting hole 211 and communicating with external liquid system.

[0043] The technical solution of this utility model involves providing a movable connector block 2 on the bottle cap 12. The movable connector block 2 is fixedly connected to the tubing assembly 3 and forms a gap with the movable opening 121, allowing the tubing assembly 3 to move around the movable opening 121 along with the movable connector block 2. When the solvent bottle 1 is replaced and the bottle cap 12 is screwed on, due to the movable nature of the movable connector block 2 and the gap with the movable opening 121, the tubing assembly 3 is not subjected to the torque and bending force generated by screwing on the bottle cap 12, thus avoiding the transmission of torque to the tubing assembly 3 and preventing the tubing assembly 3 from bending. In this solution, the tubing assembly 3 is relatively stably fixed at the mounting hole 211 of the movable connector block 2, and the adaptive movement of the movable connector block 2 protects the tubing assembly 3. At the same time, the mounting hole 211 in the thickness direction of the movable connector block 2 also provides a relatively stable fixed position for the tubing assembly 3, preventing it from being pulled and bent during the screwing on of the bottle cap 12.

[0044] Specifically, the solvent bottle 1 can be made of glass or plastic, with its volume set as needed. The bottle body 11 is cylindrical, and the cap 12 is made of elastic plastic. In use, solvents such as hemolysins are injected into the bottle body 11, and the cap 12 is screwed on to seal the bottle body 11. When the solvent bottle 1 needs to be replaced, simply unscrew the cap 12 in the reverse direction to remove it from the bottle body 11. The movable connector 2 can be made of stainless steel or other metals, or silicone or other rubbers, and its shape can be cubic or prism, etc. The specific shape and size must be compatible with the movable opening 121 on the cap 12. The movable connector 2 is placed at the movable opening 121 of the cap 12, and due to the gap between it and the opening 121, it can move within a certain range. When the cap 12 is screwed on, the movable connector 2 can make slight displacement adjustments based on its gap with the opening 121 and its own movable characteristics, thereby avoiding stress transmission to the pipeline assembly 3. The tubing assembly 3 can be a flexible hose made of materials such as silicone. One end is fixed to the mounting hole 211 of the movable connector block 2 and extends into the bottle body 11 for drawing solvent from the solvent bottle 1. The other end passes through the mounting hole 211 and connects to an external liquid system (such as an infusion pump). Throughout the process, due to the special design of the movable connector block 2, even when the bottle cap 12 is being screwed on, the tubing assembly 3 can maintain its normal shape and connection state and will not be bent. It should be noted that the fixing connection method between the tubing assembly 3 and the movable connector block 2 is not specifically limited and can be a snap-fit, rope wrapping, or threaded connection, etc.

[0045] For the procedure of replacing the body 11 of solvent bottle 1, please refer to [link / reference needed]. Figure 2 As shown, specific application scenarios are as follows:

[0046] Step 1: First, take out the solvent bottle 1 and place it on the table. The tubing assembly 3 on the bottle cap 12 needs to be long enough. In order to ensure a good user experience, the length should be between 100 and 300 mm.

[0047] Step 2: Hold the bottle body 11 and twist the bottle cap 12, or hold the bottle cap 12 and twist the bottle body 11, or twist the bottle cap 12 and the bottle body 11 at the same time, to remove the bottle cap 12, movable connector block 2 and pipeline assembly 3 as a whole assembly.

[0048] Step 3: Place the bottle cap 12 and other components into the body 11 of the new solvent bottle 1;

[0049] Step 4: Tighten the bottle cap using the method in step 2;

[0050] Step 5: Place the replaced solvent bottle 1 into the cavity of the instrument body.

[0051] In the embodiments of this utility model, please refer to Figure 3 and Figure 4The movable connector block 2 has a limiting step 20 on its outer periphery, and the edge of the movable opening 121 facing the inside of the bottle body 11 abuts against the limiting step 20. The movable connector block 2 can be made of plastic such as polyethylene or polyvinyl chloride, and its shape is cylindrical or other three-dimensional structure. The diameter and height of the movable connector block 2 are set according to the thickness of the bottle cap 12. The limiting step 20 can be an annular boss or multiple intermittent protrusions, protruding from the outer periphery of the movable connector block 2. The height and width of the limiting step 20 are set according to actual needs, as long as they are larger than the diameter of the movable opening 121 and can prevent the movable connector block 2 from passing through the upper end of the movable opening 121. During installation, the movable connector block 2 is inserted into the movable opening 121 from the inside. When the limiting step 20 of the movable connector block 2 abuts against the edge of the movable opening 121 facing the inside of the bottle body 11, it indicates that the movable connector block 2 is installed in place.

[0052] In the embodiments of this utility model, please refer to Figure 4 The movable connector block 2 includes an upper movable part 21 and a lower movable part 22 fixedly connected to the upper movable part 21. A mounting hole 211 is provided through the upper movable part 21 and the lower movable part 22, and the outer diameter of the lower movable part 22 is larger than the outer diameter of the upper movable part 21 to form a limiting step 20. Specifically, the upper movable part 21 can be a cylinder made of nylon, for example, with a diameter of 2cm and a height of 1cm, and the lower movable part 22 can be a cylinder made of polycarbonate, for example, with a diameter of 3cm and a height of 1.5cm. Thus, the outer diameter of the lower movable part 22 is larger than the outer diameter of the upper movable part 21, forming a limiting step 20 with a height of 0.5cm. When assembled onto the bottle cap 12, only the upper movable part 21 is inserted into the movable opening 121, while the lower movable part 22 is located below the edge of the movable opening 121. Optionally, the thickness of the upper movable part 21 is equal to the height of the movable opening 121, so that the upper surface of the upper movable part 21 is flush with the upper surface of the bottle cap 12.

[0053] In the embodiments of this utility model, please refer to Figure 4 The outer diameter of the upper movable part 21 is smaller than the diameter of the movable opening 121, while the outer diameter of the lower movable part 22 is larger than the diameter of the movable opening 121. This allows the movable connector block 2 to be smoothly inserted into the movable opening 121 via the upper movable part 21 during installation. Furthermore, after the lower movable part 22 is inserted to a certain extent, its outer diameter, being larger than the diameter of the movable opening 121, will be blocked by the movable opening 121 and abut against the limiting step 20, thus achieving precise positioning. The outer diameter of the lower movable part 22 is smaller than the inner diameter of the bottle cap 12. This ensures that the movable connector block 2 can be properly installed inside the bottle cap 12 while preventing excessive interference between the lower movable part 22 and the inside of the bottle cap 12. This effectively prevents the movable connector block 2 from detaching from the movable opening 121 during use.

[0054] In the embodiments of this utility model, please refer to Figure 1 and Figure 2 The piping assembly 3 includes an upper liquid pipe 31 and a lower liquid pipe 32, which are respectively installed on the upper movable part 21 and the lower movable part 22. The upper liquid pipe 31 can be made of silicone. One end of the upper liquid pipe 31 is fixedly connected to the upper movable part 21 by a clamp or a rope, firmly fixing the upper liquid pipe 31 near the mounting hole 211 of the upper movable part 21. The other end is connected to the next-level component (such as a small liquid pump or a diversion device) of the hemolytic agent delivery system inside the blood cell analyzer 200. The lower liquid pipe 32 can be made of polytetrafluoroethylene, which has advantages such as low friction coefficient and corrosion resistance. One end of the lower liquid pipe 32 is fixed to the lower movable part 22 by a threaded connection (the lower movable part 22 has a threaded structure at the mounting hole 211) or by a snap-fit, ensuring a firm connection. The other end extends to the vicinity of the bottom of the hemolytic agent bottle for drawing the hemolytic agent from the bottle.

[0055] In the embodiments of this utility model, please refer to Figure 1 The piping assembly 3 also includes a sinker 33, which is installed at the bottom of the dispensing tube 32 and positioned close to the bottom of the bottle body 11. The sinker 33 can be made of stainless steel and is spherical or prismatic in shape, possessing a certain weight and corrosion resistance. The sinker 33 is installed at the bottom of the dispensing tube 32 by welding or a special clamping structure. In this way, when close to the bottom of the bottle body 11, the sinker 33 always maintains a distance of approximately 0.5 cm from the bottom of the bottle, ensuring that the dispensing tube 32 can stably draw the hemolysin from the bottom of the bottle while preventing the sinker 33 from directly contacting the bottom of the bottle and causing wear or blockage of the dispensing tube 32.

[0056] In the embodiments of this utility model, please refer to Figure 3 and Figure 4The built-in hemolytic agent bottle 100 also includes a sleeve 4, which is installed at the mounting hole 211, with both ends of the sleeve 4 extending out of the mounting hole 211 to connect to the upper liquid tube 31 and the lower liquid tube 32, respectively. The sleeve 4 can be made of rigid plastic such as polycarbonate. The diameter of the sleeve 4 must match the outer diameter of the upper liquid tube 31 and the lower liquid tube 32. The length of the sleeve 4 must ensure that both its upper and lower ends extend at least 1.5 cm out of the mounting hole 211 to facilitate clamping or screwing with the upper liquid tube 31 and the lower liquid tube 32. Optionally, the ends of the upper liquid tube 31 and the lower liquid tube 32 can be chamfered to facilitate insertion of the sleeve 4, and a clamp or sealant can be used for sealing after insertion. It should be noted that the sleeve 4 and the mounting hole 211 can be connected by threads or adhesive. If a threaded connection is used, the external thread of the sleeve 4 must match the internal thread of the mounting hole 211, for example, with a thread pitch of 0.5 mm and a thread length of 1 cm. If bonding is used, a gap should be provided between the outer wall of the sleeve 4 and the wall of the mounting hole 211 to facilitate the filling of adhesive; alternatively, the outer surface of the sleeve 4 and the inner surface of the mounting hole 211 can be polished to increase the bonding area and ensure the bonding effect.

[0057] In the embodiments of this utility model, please refer to Figure 6 The outer periphery of the sleeve 4 is provided with a positioning protrusion 41, and the wall of the mounting hole 211 is provided with a positioning step 212. The positioning protrusion 41 and the positioning step 212 are abutted together. The positioning protrusion 41 can be annular or multiple intermittent protrusions. Preferably, the distance between the positioning protrusion 41 and one end of the sleeve 4 is at least 1 cm, so as to better match it with the positioning step 212 of the mounting hole 211. Furthermore, the two end faces of the sleeve 4 are chamfered to facilitate connection with the upper liquid pipe 31 and the lower liquid pipe 32.

[0058] In the embodiments of this utility model, please refer to Figure 5The movable connector block 2 is provided with a vent 23, which connects the inside and outside of the bottle cap 12. The vent 23 can be any shape, as long as it can connect to the inside of the bottle body 11. Optionally, to prevent external impurities from entering the bottle cap 12 through the vent 23, a fine filter screen with a pore size of 0.1mm is provided on the inner side of the vent 23 (the end closer to the inside of the bottle cap 12), which can effectively block impurities such as dust and microorganisms. Thus, during the use of the blood cell analyzer 200, the air pressure inside the bottle cap 12 will change as the hemolytic agent is consumed. The vent 23 can keep the air pressure inside and outside the bottle cap 12 balanced. For example, when the hemolytic agent is drawn out, the air pressure inside the bottle cap 12 and the bottle body 11 decreases. Without the vent 23, the external air pressure would exert inward pressure on the bottle cap 12, which may affect the normal absorption of the hemolytic agent by the lower tube 32, and may even cause the bottle body 11 to deform. The presence of vent 23 prevents this from happening, ensuring a stable supply of hemolytic agent.

[0059] This utility model also proposes a blood cell analyzer 200, please refer to [link / reference needed]. Figure 7 The hematology analyzer 200 includes an instrument body and a built-in hemolysin bottle 100. The instrument body has an internal cavity, and the built-in hemolysin bottle 100 is located inside the cavity. The specific structure of the built-in hemolysin bottle 100 is as described in the above embodiments. Since this hematology analyzer 200 adopts all the technical solutions of all the above embodiments, it possesses at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be elaborated further here. When the instrument body starts the hematology analysis program, according to the program settings, if a hemolysin is required to participate in the analysis process, under the action of the relevant driving device inside the instrument (such as an air pump), the hemolysin in the hemolysin bottle is transported to the designated analysis area through the tubing assembly 3 to mix with the blood sample for hemolysis and other operations. When it is necessary to replace the hemolytic agent bottle, the operator can open the corresponding door of the instrument body and follow the bottle replacement operation mentioned above. Twist the bottle cap 12 to remove the old bottle and replace it with a new bottle. Due to the setting of the movable connector block 2 on the built-in hemolytic agent bottle 100, this process will not affect other internal components of the instrument, and the tubing assembly 3 will not be bent.

[0060] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
