Description

Technical Field

[0001] The present application relates to the technical field of blood purifier manufacturing, and in particular to a glue injection dispenser used in the manufacturing of blood purification equipment. Background Art

[0002] A blood purifier is a medical device used to treat a variety of conditions, including renal failure, poisoning, immune disorders, and liver disease. It purifies the blood by filtering, adsorbing, or replacing the kidney's function. A hemodialyzer is one of the most common blood purifiers, used for renal function replacement therapy in patients with chronic kidney disease. Blood and dialysate exchange solutes across a semipermeable membrane, removing metabolic waste and excess water from the blood.

[0003] Existing publication number CN221132946U discloses a dialyzer glue injection box, comprising a one-piece housing with a concave top forming a glue-holding cavity. Multiple glue-dispensing channels are provided on the outer wall. One end of each glue-dispensing channel communicates with the glue-holding cavity, and the other end communicates with the D-pillar hole on the dialyzer housing via a glue injection tube. The present invention, due to its one-piece housing, eliminates glue leakage, ensures uniform glue discharge from the glue-dispensing channels, and prevents glue contamination on the product surface, thereby improving product yield.

[0004] In view of the above-mentioned prior art, an integrated shell is adopted to avoid glue leakage and ensure uniform glue output. However, since the shell is molded in one piece, the setting of the ribs causes the bottom of the glue cavity to form a downward bulge, that is, a depression is formed inside the glue cavity. The ribs will interfere with the natural flow of glue, especially under the action of centrifugal force, the glue will be retained around the ribs, resulting in uneven glue deposition and potential bubble formation. More glue will remain in the depression at the bottom of the glue cavity. When the glue hardens, the residual glue in the depression is difficult to clean, which increases the cost of cleaning and maintenance. In order to solve the above problems, a glue injection dispenser for the production of blood purification equipment is proposed.

[0005] The above information disclosed in this background technology is only used to increase the understanding of the background technology of this application. Therefore, it may contain information that does not constitute the prior art known to ordinary technicians in this field. Utility Model Content

[0006] In order to solve the problem of manufacturing blood purifiers, the present application provides a glue injection dispenser for manufacturing blood purification equipment.

[0007] The present application provides a glue injection dispenser for manufacturing a blood purification device using the following technical solution:

[0008] A glue injection dispenser for use in the manufacture of blood purification equipment comprises an outer shell, which is cylindrical. A glue holding cavity for glue injection is provided in the outer shell. A flow guide platform for flow diversion is provided at the bottom of the glue holding cavity, and the flow guide platform is conical. A glue outlet pipe for glue injection distribution is also provided on the outer shell, and the glue outlet pipe is conical and arranged at an angle.

[0009] Preferably, the glue outlet pipe extends outward from the connection with the outer wall of the shell and tilts downward.

[0010] Preferably, the rubber outlet pipes are circumferentially arranged outside the shell, and the number of the rubber outlet pipes is an even number.

[0011] Preferably, a connecting ring is fixed to one end of the glue outlet pipe away from the shell, and a short glue injection tube is provided on the inner thread of the connecting ring.

[0012] Preferably, the inner wall of the glue containing cavity is provided with distribution openings having the same number as the glue outlet pipes, and the glue outlet pipes are communicated with the inner cavity of the shell.

[0013] Preferably, a fixing block is provided on the outside of the shell, and the fixing block is located between two adjacent rubber outlet pipes.

[0014] In summary, this application has the following beneficial technical effects:

[0015] By setting the shell body to be cylindrical, a glue containing cavity is opened inside the shell, a conical flow guide platform is provided in the glue containing cavity, and a tilted conical glue outlet pipe is also provided on the shell. Compared with the related technology, the setting of the cylindrical shell makes it easier for the glue in the glue containing cavity to form a stable fluid dynamic pattern under the action of centrifugal force, thereby promoting the uniform flow and distribution of the glue in the glue containing cavity. At the same time, the conical glue outlet pipe can guide the glue to smoothly transition from a wider inlet to a narrower outlet, which can reduce the formation of bubbles when the glue is injected into the hemodialyzer, ensuring the purity of the glue and the quality of the injection. The tilted setting of the conical glue outlet pipe reduces the dead angle of the connection between the glue outlet pipe and the cylindrical shell, making it easier to remove residual glue during cleaning, reducing the difficulty and frequency of cleaning and maintenance.

[0020] The following is combined with Figure 1-3 This application is described in further detail.

[0021] The embodiment of the present application discloses a glue injection dispenser for making a blood purification device. Figure 1-3 A glue injection dispenser for blood purification equipment includes a shell 1, which is cylindrical. A glue cavity 9 for glue injection is provided in the shell 1. A guide platform 2 for guiding flow is provided at the bottom of the glue cavity 9. The guide platform 2 is conical. A glue outlet pipe 4 for glue injection distribution is also provided on the shell 1. The glue outlet pipe 4 is conical and inclined.

[0022] It should be noted that the conical design of the guide platform 2 allows the glue to flow evenly along the conical surface of the guide platform 2 to the glue outlet pipe 4 under the action of centrifugal force, preventing the glue from accumulating at the bottom to form an uneven layer. At the same time, the conical guide platform 2 reduces the dead angle area in the glue holding cavity 9, and the inclined setting of the glue outlet pipe 4 helps to reduce the glue residue in the glue holding cavity 9, making cleaning easier.

[0023] By adopting the above technical solution, glue is injected into the glue containing cavity 9. During centrifugal glue injection, the glue flows evenly into the glue outlet pipe 4 under the guidance of the guide table 2. The conical glue outlet pipe 4 is tilted to reduce the dead angle of the connection between the glue outlet pipe 4 and the cylindrical shell 1. The shell 1 is a regular cylindrical shape, which makes it easier to remove residual glue during cleaning, reducing the difficulty and frequency of cleaning and maintenance.

[0024] Reference Figure 2 , the rubber outlet pipe 4 extends outward from the connection with the outer wall of the shell 1 and tilts downward;

[0025] It should be noted that the rubber outlet pipe 4 is a cone that gradually tightens from the housing 1 outwards;

[0026] By adopting the above technical solution, the tapered glue outlet pipe 4 is tilted, which can optimize the mechanical properties of the glue flow, so that the kinetic energy of the glue when flowing out of the glue cavity 9 can be better utilized, the glue injection speed can be accelerated, and the production efficiency of the hemodialyzer can be improved.

[0027] Reference Figure 3 The rubber outlet pipe 4 is circumferentially arranged outside the housing 1, and the number of the rubber outlet pipe 4 is an even number;

[0028] It should be noted that the number of the glue outlet pipes 4 is an even number, and two glue outlet pipes 4 arranged opposite to each other can complete the glue injection work of a hemodialyzer;

[0029] By adopting the above technical solution, the setting of multiple glue outlet tubes 4 can inject glue into multiple hemodialyzers at the same time, which can reduce the eddy current effect generated during glue injection, avoid local excessive glue injection or bubble generation, thereby increasing the glue injection speed, shortening the production cycle, and reducing the scrap rate caused by uneven glue injection.

[0030] Reference Figure 2 A connecting ring 5 is fixed to one end of the rubber outlet pipe 4 away from the housing 1, and a short rubber injection pipe 6 is provided on the inner thread of the connecting ring 5;

[0031] It should be noted that a long glue injection tube 7 is also threadedly provided in the connecting ring 5, and a short glue injection tube 6 and a long glue injection tube 7 are respectively threadedly connected to two adjacent connecting rings 5. The two oppositely arranged short glue injection tubes 6 or long glue injection tubes 7 complete the glue injection work of one hemodialyzer, and one glue injection distributor can complete the glue injection work of at least two hemodialyzers at the same time.

[0032] It should be further explained that, in order to ensure the sealing of the connection between the short glue injection tube 6 or the long glue injection tube 7 and the glue outlet tube 4, a sealing ring can be provided in the connecting ring 5;

[0033] By adopting the above technical solution, the provision of multiple short glue injection tubes 6 and long glue injection tubes 7 allows for simultaneous glue injection for multiple hemodialyzers, significantly improving production efficiency and output. At the same time, the detachability of the short glue injection tubes 6 and the long glue injection tubes 7 allows them to be independently removed for cleaning and maintenance after use, which is both convenient and quick, and reduces downtime.

[0034] Reference Figure 1 The inner wall of the glue cavity 9 is provided with a distribution port 3 equal to the number of the glue outlet pipes 4, and the glue outlet pipes 4 are connected to the inner cavity of the shell 1;

[0035] It should be noted that the connection between the distribution port 3 and the glue outlet pipe 4 is rounded, which can reduce the turbulence of the glue at the connection, avoid excessive bubbles in the glue flow process, and ensure the quality of glue injection;

[0036] By adopting the above technical solution, the distribution port 3 is used to evenly distribute the glue in the glue holding cavity 9 to the glue outlet pipe 4 in cooperation with the centrifugal action.

[0037] Reference Figure 1 , a fixing block 8 is provided on the outside of the housing 1, and the fixing block 8 is located between two adjacent rubber outlet pipes 4;

[0038] It should be noted that the fixing block 8 is clearance-matched with the limiting rod on the centrifuge, and plays a positioning role when the glue dispenser injects glue;

[0039] By adopting the above technical solution, the fixed block 8 can ensure the accurate position of the hemodialyzer during the centrifugal injection process, prevent it from shifting or shaking during high-speed rotation, help maintain the accuracy and uniformity of the injection, and ensure that the injection amount and position of each dialyzer meet production requirements.

[0040] The implementation principle of the glue injection dispenser for making blood purification equipment in an embodiment of the present application is as follows: when in use, the short glue injection tube 6 and the long glue injection tube 7 are respectively inserted into the glue injection port of the hemodialyzer. At this time, the fixed block 8 is inserted on the limit rod corresponding to the centrifuge, and glue is added into the glue containing cavity 9. Under the action of centrifugal force, the glue is evenly distributed along the conical surface of the guide table 2 to the glue outlet tube 4 and the short glue injection tube 6 and the long glue injection tube 7 connected thereto. The cooperation between the cylindrical shell 1 and the inclined conical glue outlet tube 4 reduces the dead angle area in the glue containing cavity 9, reduces glue residue and reduces the difficulty of cleaning.
