For some products, such as catheter pumps, the handle and sleeve parts cannot touch water, so they cannot be completely immersed in the solution. At the same time, there are tiny channels in the connection between the motor and the impeller of the catheter pump. Therefore, when cleaning the catheter pump, water droplets should be prevented from entering the motor, which will make drying difficult or even impossible. In addition, ultrasonic cleaning will cause the bonding strength of some bonding parts to decrease, affecting the quality of the catheter pump. Therefore, the cleaning of catheter pumps has always been a major problem that needs to be solved in the industry. Summary of the invention

DETAILED DESCRIPTION

[0016] In order to highlight the technical effect of the present invention, it is necessary to briefly introduce the particularity of products such as catheter pumps. A catheter pump is a device that is inserted percutaneously into the heart and pumps blood from the left ventricle into the aorta to assist blood circulation and maintain the patient's life. The entire length of the catheter pump is greater than 1500mm, and the area below the sterile sleeve needs to be cleaned. Its length is also very long, so in the design of the cleaning machine, the stability of the long-distance linear drive mechanism is a design point. Figure 1-Figure 11 The present invention is described in further detail.

[0017] like Figure 1-Figure 4As shown, a cleaning machine includes a box body 10, a spray mechanism 20 is arranged inside the box body 10, and a linear drive mechanism 30 is arranged outside the box body 10. A strip hole 11 is opened on the side box plate 13 of the box body 10. The strip hole 11 here is not used for limiting, so the width requirement of the strip hole 11 is not high. The connecting bracket 40 passes through the strip hole 11 to connect the spray mechanism 20 and the linear drive mechanism 30. Here, the linear drive mechanism 30 is arranged outside the box body 30, and is physically separated from the cleaning area to prevent impurities such as lubricating oil in the linear drive mechanism 30 from contaminating the product. The power of the linear drive mechanism 30 is transmitted to the spray mechanism 20 inside the box body 10 through the connecting bracket 40, driving the spray mechanism 20 to make a linear motion, and spraying and cleaning the product. The stroke of the spray mechanism 20 corresponds to the range of the product that needs to be cleaned, and it avoids the parts that do not need to be cleaned.

[0018] As a preferred solution of the present invention, the linear drive mechanism 30 includes a motor 31, the shaft of the motor 31 is fixed to a screw 32 through a coupling, the length direction of the screw 32 is arranged vertically, a nut slider 33 is sleeved on the screw 32, the nut slider 33 is connected to the connecting bracket 40, and the motor 31 drives the screw 32 to rotate to drive the connecting bracket 40 and the spray mechanism 20 to perform linear motion in the vertical direction. The screw slider transmission mechanism has significant advantages in transmission stability, accuracy, transmission efficiency and carrying capacity, so we choose the screw slider transmission mechanism here. Considering the characteristics of the product to be cleaned (here, the catheter pump), the handle part and the sleeve part cannot touch water. There is a tiny channel in the connection between the motor and the impeller of the catheter pump, and many connection parts are connected by gluing. Therefore, the catheter pump must be hung in a vertical posture during cleaning. The handle part and the sleeve part of the catheter pump are located at the upper part, and the catheter part and the pump head assembly part are located at the lower part. The linear drive mechanism 30 drives the spray mechanism 20 to make a linear motion in the area below the sleeve part, avoiding the handle part and the sleeve part to prevent water droplets from entering the handle part and the sleeve part. Therefore, the screw rod 32 is arranged vertically here to drive the spray mechanism 20 to make a linear motion vertically.

[0019] In order to realize that the linear drive mechanism 30 outside the box 10 can drive the spray mechanism 20 inside the box 10 to move, refer to Figure 9-11The connecting bracket 40 includes a first bracket 41 with a U-shaped cross-section and a second bracket 42 with a U-shaped cross-section. The first bracket 41 is arranged outside the box 10. A plurality of first connecting holes 412 are arranged in the middle of a first bottom plate 411 of the first bracket 41. Bolts pass through the first connecting holes 412 to connect with the nut slider 33. The second bottom plate 421 of the second bracket 42 is located inside the box 10. The two second side plates 422 of the second bracket 42 pass through the strip hole 11 to the outside of the box 10. Second connecting holes 423 are arranged on the two second side plates 422 of the second bracket 42. Third connecting holes 414 are also opened on the two first side plates 413 of the first bracket 41 corresponding to the two second side plates 422 of the second bracket 42. Bolts pass through the second connecting holes 423 and the third connecting holes 414 in sequence to connect the first bracket 41 and the second bracket 42. That is to say, the connecting bracket 40 is not an integral structure, but a split structure formed by the first bracket 41 and the second bracket 42 being connected. In this way, during installation, the first bracket 41 is first fixed to the linear drive mechanism 30, and then the spray mechanism 20 is fixed to the second bracket 42. The two second side plates 422 of the second bracket 42 are respectively connected to the two first side plates 413 of the first bracket 41 after passing through the two strip holes 11, forming a whole, simplifying the installation process. At the same time, this split structure can also absorb and compensate for the deformation of the transmission mechanism, ensuring the reliability of its linear motion.

[0020] As mentioned above, the length of the catheter pump is relatively long, so the length of the screw rod 32 must also be set long enough, which will cause the screw rod 32 to be disturbed too much, resulting in the nut slider 33 being unable to slide, and the motor operation being blocked. In order to solve this problem, the first connecting hole 412 is a waist-shaped hole and the length of the waist-shaped hole is parallel to the length of the first bottom plate 411, the second connecting hole 423 or the third connecting hole 414 is a waist-shaped hole and the length direction of the waist-shaped hole is parallel to the length direction of the second side plate 422 of the second bracket 42, and the length of the first connecting hole 412 is perpendicular to the length direction of the second connecting hole 423 / the third connecting hole 414. The first connecting hole 412 is set as a waist-shaped hole structure, and the second connecting hole 423 or the third connecting hole 414 is set as a waist-shaped hole structure. Compared with a circular hole, the waist-shaped hole has a larger deformation space, allowing the nut slider 33 to make a small position adjustment within a certain range, compensating for the disturbance deformation of the screw rod 32, ensuring the smooth sliding of the nut slider 33, avoiding the jamming phenomenon, and ensuring the stability and accuracy of the entire mechanism. In addition, the waist-shaped hole design can reduce stress concentration and help disperse stress to a larger area, thereby improving the strength and durability of the connected parts.

[0021] Considering that the side box plate 13 of the box body 10 is too large, it will deform, causing the screw rod 32 to also deform, and the rotation of the nut slider 33 thereon is hindered, and the operation of the motor 31 is hindered. Figure 5-Figure 7As shown, two steel pipes 50 are arranged outside the box body 10, and the upper and lower ends of the steel pipes 50 are respectively fixed to the box body frame 12 and the steel pipes 50 are arranged in the vertical direction. A sheet metal 60 is arranged between the steel pipe 50 and the side box plate 13 of the box body 10, and the sheet metal 60 is fixedly connected to the steel pipe 50 and separated from the sheet metal 60. The motor 31 is fixed to the upper part of the sheet metal 60, and the lower part of the sheet metal 60 is provided with a bearing seat 61. The lower end of the screw rod 32 is placed in the bearing seat 61 and forms a rotation fit. The two steel pipes 50 are not fixed to the side box plate 13, but directly fixed to the box body frame 12, so as to ensure the verticality of the steel pipe 50. The plate surface of the sheet metal 60 directly fixed on the steel pipe 50 is kept in the vertical direction as a whole. In addition, the area of ​​the sheet metal 60 is small, and its deformation is small and can be ignored. The linear drive mechanism 30 is directly fixed on the sheet metal 60, which can ensure the straightness of the screw rod 32, and then ensure the smooth sliding of the nut slider 33.

[0022] Furthermore, the cross section of the sheet metal 60 is a multi-stage bending shape, such as Figure 8 As shown, it includes a center plate 62 whose plate surface is located in the vertical plane, and the gap between the center plate 62 and the side box plate 13 is δ1. Extension plates 63 are also arranged on both sides of the center plate 62. The extension plates 63 are parallel to the plate surface of the center plate 62, and the gap between the extension plates 63 and the side box plate 13 is δ2, δ1>δ2, that is, the sheet metal 60 is separated from the side box plate 13 and is not affected by the deformation of the side box plate 13. The extension plate 63 and the center plate 62 are connected by a transition plate 64, and the plate surface of the transition plate 64 is perpendicular to the center plate 62. The steel pipe 50 is placed in the angle between the transition plate 64 and the extension plate 63 and welded, so as to increase the welding area between the sheet metal 60 and the steel pipe 50, improve the reliability of the connection between the two, and ensure the rigidity of the sheet metal 60.

[0023] In order to ensure the linear motion of the linear drive mechanism 30, a flange plate 65 is extended from the outer plate edge of the extension plate 63 toward the side away from the side box plate 13. A guide column 34 is provided on both sides of the screw rod 32. The guide column 34 is arranged in the vertical direction. The mounting seats 35 at the upper and lower ends of the guide column 34 are respectively fixed to the upper and lower parts of the flange plate 65. A guide sleeve 36 is provided on the connecting bracket 40. The guide column 34 is inserted into the guide sleeve 36 to form a guide fit. The linear motion of the nut slider 33 is ensured by providing a guide structure on both sides. The parallelism of the screw rod 32 and the guide column 34 also plays a vital role in the centroid motion of the nut slider 33, so the guide column 34 is also provided on the sheet metal 60 to ensure the parallelism of the two.

[0024] In order to further improve the connection reliability between the connecting bracket 40 and the linear drive mechanism 30, the guide sleeve 43 corresponds to the second connecting hole 421 and the third connecting hole 412, and the bolts pass through the second connecting hole 421 and the third connecting hole 412 in turn to connect the guide sleeve 43 to the connecting bracket 40, that is, the position of the guide sleeve 43 can also be slightly adjusted to ensure the parallelism of the guide column 34 and the screw rod 32.

[0025] Preferably, a photoelectric sensor 90 is provided at the upper and lower parts of the center plate 62, and a first bottom plate 412 of the first bracket 41 is provided with a protrusion 415 protruding toward the photoelectric sensor 90, and a receiver 91 is mounted on the protrusion 415. The photoelectric sensor 90 detects the position of the receiver 91 and triggers the reversing function. The position of the photoelectric sensor 90 can also be adjusted to adjust the range of the spray mechanism 20 and the wind knife 70 to move up and down, thereby adjusting the flushing and blowing ranges and realizing the reversing function.

[0026] The spray mechanism 20 is fixedly connected to the bottom plate of the second bracket 42, and an air knife 70 is also arranged on the bottom plate of the bottom plate of the second bracket 42. The spray mechanism 20 implements the flushing operation, and the air knife 70 implements the purge operation. The ball valve is connected to the water circuit, and the solenoid valve is connected to the air circuit, and both are connected to the time relay. By controlling the switch of the ball valve and the solenoid valve, the water circuit and the air circuit are turned on and off. At the same time, the flushing time is adjusted by the control of the time relay and the ball valve, and the flushing is automatically turned off after the flushing time is reached, and the air knife purge function is automatically switched to realize full automatic control and improve the cleaning efficiency.

[0027] like Figure 3-Figure 4 As shown, a turntable 14 is provided at the bottom of the box 10, and the product rack 80 is placed on the turntable 14 to form a detachable connection. The rotation speed of the turntable 14 is very slow to prevent the catheter pump on the rack 80 from being thrown up and adsorbed. Casters 15 are also provided at the four corners of the bottom of the box 10 to facilitate the movement of the box 10. The outer cover of the linear drive mechanism 30 is provided with a cover plate 16 to prevent external impurities from entering and affecting the smooth movement of the linear drive mechanism 30. At the same time, it is also beautiful.

[0028] When the above cleaning machine is used to clean the catheter pump product, since the handle part and the sleeve part are located in the upper area of ​​the box body 10, the catheter part is located in the middle area, and the pumping component part is located in the lower area, the travel range of the spray mechanism 20 and the wind knife 70 can be set in the catheter part and the area below, and the handle part and the sleeve part will not be cleaned, or the handle part and the sleeve part are shielded by the baffle-like components on the bracket 80 to avoid splashing of the cleaning liquid. At the same time, in this hanging posture of the catheter pump, the motor shaft is downward, and the cleaning liquid also flows downward, so the cleaning liquid will not enter the motor from the bearing to avoid damaging the motor performance.

[0029] The above shows and describes the basic principles, main features and characteristics of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments, and the above embodiments and descriptions are only for explaining the principles of the present invention.
