Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some embodiments of the present application, but not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
The present application provides a circulation pump (not shown) comprising a pump body (not shown), a displacement carriage (not shown), and a drive pump fixture 10 (hereinafter simply referred to as drive pump fixture 10) for an extracorporeal blood circulation apparatus as described above. One end of the driving pump fixing device 10 is connected to a connecting rod of the displacement vehicle, and the other end is connected with the pump body.
As shown in fig. 1-3, the present application also provides a drive pump fixture 10 including a body 100, a clamping mechanism 200, and an adjustment mechanism 300. The main body 100 is in a shape of a long strip, and a first end 110 and a second end 120 are disposed along a length direction thereof. The clamping mechanism 200 is rotatably connected to the first end 110 for connection to a bracket on a displacement cart of an extracorporeal blood circulation apparatus; the adjustment mechanism 300 is rotatably coupled to the second end 120 and is configured to externally engage a backup pump.
The clamping mechanism 200 includes a base 210 and a movable clamp 220. The base 210 is rotatably connected to the first end 110. The fixed end of the movable clip 220 is rotatably connected with the base 210. The movable end of the movable clip 220 rotates close to the seat body 210 to connect with the bracket on the displacement cart of the extracorporeal blood circulation apparatus.
Therefore, in the above-mentioned driving pump fixing device 10, the movable clip 220 and the base 210 form an eccentric clamping structure, so that the driving pump fixing device 10 can be firmly fixed on the bracket of the extracorporeal blood circulation apparatus displacement vehicle, and the clamping mechanism 200 can be rotated relative to the main body 100 by controlling the adjusting mechanism 300, that is, the adjusting mechanism 300 and the main body 100 can be controlled to rotate relative to the clamping mechanism 200 and the bracket of the extracorporeal blood circulation apparatus displacement vehicle, so as to adjust the orientation of the backup pump, thereby facilitating the storage, transportation and use of the backup pump. In addition, the user only needs to control the movable clamp 220 to rotate relative to the base 210, so that the drive pump fixing device 10 and the support can be fixed and separated, the fixing device and the support can be rapidly installed and detached, and the use convenience of the device is improved.
It should be noted that, in the process of rotating the movable end of the movable clip 220 toward the direction close to the seat body 210, the pressure of the movable clip 220 and the seat body 210 on the bracket of the displacement vehicle of the extracorporeal blood circulation apparatus gradually increases until the bracket is clamped, so as to fix the driving pump fixing device 10 and the bracket firmly. In the process of rotating the movable clip 220 to rotate the movable end thereof in the direction away from the seat body 210, the pressure of the movable clip 220 and the seat body 210 on the bracket is gradually reduced, and when the pressure is reduced to a certain range, the user can detach the driving pump fixing device 10 from the bracket.
The "eccentric" clamping structure formed by the movable clamp 220 and the base 210 can be understood as follows: when the movable clip 220 rotates relative to the base 210, the axis of the rotation axis of the movable clip 220 is located on one side of the movable clip 220, and the movable clip 220 does not "rotate" around the central axis of its own structure.
Because in the current device of fixing spare pump and extracorporeal blood circulation equipment displacement car, all adopt the mode of screw connection to it is fixed with extracorporeal blood circulation equipment displacement car with the spare pump, the unable adjustment of position of spare pump, and dismantle very inconveniently. In addition, after the displacement vehicle is used for a period of time, the screw can be loosened, so that the situation that the standby pump is connected unstably and even falls off from the displacement vehicle is caused, and much inconvenience is brought to a user. The rotary eccentric clamping structure can overcome various defects of screw connection, and can be conveniently detached and keep the connection stable.
Spare driving pump often places in the displacement car, and this kind of driving pump fixing device 10 that this application provided can be dismantled, and the user can select whether to dismantle driving pump fixing device 10 according to actual conditions to alleviate the heavy burden of displacement car, of course, the user also can select whether to place spare pump according to actual conditions.
In one embodiment, as shown in fig. 1 and 3, the first end 110 is opened with a first through hole 111 along a first direction (e.g., a direction indicated by an arrow T in fig. 1). The first direction is perpendicular to the length direction of the body 100. The base 210 has a first rotating column 211 formed along a first direction. The first rotating post 211 is inserted into the first through hole 111 and can rotate at an arbitrary angle with respect to the main body 100.
As can be seen from this, the clamp mechanism 200 can be rotated about the axis of the first through hole 111, but it can be understood that: the body 100 is rotatable about the axis of the first through hole 111. Therefore, when the clamping mechanism 200 is fixed to the stand, the user can adjust the orientation of the adjustment mechanism 300 and the back-up pump by rotating the main body 100 during the movement of the cart of the extracorporeal blood circulation apparatus, thereby preventing the back-up pump from being damaged during the movement.
The first rotating column 211 can rotate at any angle with respect to the main body 100, that is, the main body 100 can rotate at any angle with respect to the first rotating column 211.
In one embodiment, as shown in fig. 1 and 2, the clamping mechanism 200 further includes a first rotating shaft 230 having a length direction parallel to the first direction. A first recess 213 is disposed on a side of the base 210 facing the movable clip 220. A second recess 221 is formed on a side of the movable clip 220 facing the base 210. When the movable clip 220 rotates around the first rotating shaft 230 to the clamping position, the first concave portion 213 and the second concave portion 221 are attached to the outer wall of the bracket.
It will be appreciated that when the movable clamp 220 is rotated to the clamping position, the first recess 213 and the second recess 221 are adapted to the outer wall of the holder of the extracorporeal blood circulation apparatus displacement vehicle to be connected, so as to ensure the stability of the connection. For example: when the holder is cylindrical, the first recess 213 and the second recess 221 are both arc-shaped and can be attached to the outer wall of the cylindrical holder.
Further, the first concave portion 213 and/or the second concave portion may be attached with a silicone pad to increase a friction coefficient between the first concave portion 213 and/or the second concave portion 221 and the bracket, thereby facilitating to improve the stability of the connection between the movable clamp 220 and the base 210 and the bracket.
In one embodiment, as shown in FIG. 3, the clamping mechanism 200 further includes a retaining member 240. One end of the locking member 240 is connected to the holder body 210. When the movable clip 220 rotates to the clamping position, the locking member 240 is used to fix the movable clip 220 and the seat body 210.
It should be noted that the locking member 240 can further increase the pressure of the movable clamp 220 and the holder body 210 on the bracket, thereby further improving the stability of the connection of the clamping mechanism 200 and the driving pump fixing device 10 with the bracket.
In one embodiment, as shown in fig. 1 and 3, the first end 110 is opened with a second through hole 112 along a second direction (indicated by the arrow S in fig. 1). The second direction is perpendicular to the first direction, and the second direction is also perpendicular to the length direction of the body 100. The drive pump securing device 10 further includes a first adjustment member 410. One end of the first adjusting member 410 inserted in the second through hole 112 is used for abutting against the side wall of the first rotating column 211. Accordingly, after the control body 100 is rotated to a desired position with respect to the clamping mechanism 200, the first adjuster 410 may be inserted into the second through-hole 112 to abut against the sidewall of the first rotating post 211, thereby fixing the positions of the control body 100 and the clamping mechanism 200.
Further, the sidewall of the first rotating column 211 is provided with a plurality of first grooves 2111 at intervals. One end of the first adjusting member 410 is inserted into one of the first grooves 2111 to restrict the first rotating cylinder 211 from rotating with respect to the main body 100. Therefore, the first notch 2111, into which one end of the first adjusting member 410 can be inserted, is provided on the first rotating column 211, so that the resistance between the first adjusting member 410 and the first rotating column 211 can be further increased, thereby more stably limiting the first rotating column 211 from continuing to rotate.
It should be noted that the number of the first grooves 2111 may be two, three, four, etc. When the number of the first grooves 2111 is two, the first adjusting piece 410 is inserted into the first groove 2111 after the adjustable main body 100 is rotated 180 ° with respect to the first rotating column 211 to fix the main body 100 with respect to the clamping mechanism 200; when the number of the first grooves 2111 is three, the first adjusting piece 410 is inserted into the first groove 2111 after the adjustable main body 100 is rotated 120 ° with respect to the first rotating column 211 to fix the main body 100 with respect to the clamping mechanism 200; when the number of the first grooves 2111 is four, the first adjusting member 410 is inserted into the first groove 2111 after the adjustable body 100 is rotated 90 ° with respect to the first rotating post 211 to fix the body 100 with respect to the clamping mechanism 200, and so on.
In one embodiment, as shown in fig. 1 and 3, adjustment mechanism 300 includes a base 310, an adjustment member 320, and a quick-fit plate 330. The base 310 is pivotally connected to the second end 120. The adjusting member 320 and the quick-mounting plate 330 are respectively connected to two sides of the base 310 facing away from each other. The adjusting member 320 is used to control the rotation of the quick-mounting plate 330. The quick-install plate 330 is used to externally connect a backup pump. The rotation plane of the quick-mounting plate 330 is perpendicular to the length direction of the main body 100.
Therefore, the user can control the spare pump to rotate on the plane vertical to the length direction of the main body 100 according to actual needs, so as to properly adjust the inclination angles of the driving pump and the pump head according to complex clinical conditions, and adjust the blood outlet direction of the pump head and the direction of the connected pipeline.
Further, as shown in fig. 1 and 3, the second end 120 is opened with a third through hole 121 along a third direction (the direction indicated by the U arrow in fig. 1). The third direction is perpendicular to the longitudinal direction of the body 100. The base 310 is provided with a second rotating column 311 in the third direction. The second rotating post 311 is inserted into the third through hole 121 and can rotate at any angle with respect to the main body 100.
Therefore, the adjusting mechanism 300 can rotate around the axis of the third through hole 121, so that when the clamping mechanism 200 is fixed with the bracket, a user can adjust the orientation of the standby pump by rotating the adjusting mechanism 300 during the movement of the displacement cart of the extracorporeal blood circulation apparatus, thereby avoiding damaging the standby pump during the movement. The second rotating column 311 can rotate at any angle with respect to the main body 100.
In one embodiment, as shown in fig. 1 and 3, the second end 120 is opened with a fourth through hole 122 along a fourth direction (the direction indicated by the arrow V in fig. 1). The fourth direction is perpendicular to the third direction and perpendicular to the length direction of the body 100. The drive pump securing device 10 further includes a second adjustment member 420. The second adjusting member 420 is inserted into the fourth through hole 122 at one end thereof for abutting against the sidewall of the second rotating post 311. Therefore, after controlling the adjustment mechanism 300 to rotate to a desired position with respect to the shield body, the second adjuster 420 may be inserted into the fourth through hole 122 to abut against the sidewall of the second rotation column 311, thereby fixing the position of the adjustment mechanism 300 and the main body 100.
Further, the sidewall spacer ring of the second rotating column 311 is provided with a plurality of second grooves 3111. One end of the second adjusting member 420 is inserted into a second groove 3111 to restrict the second rotating cylinder 311 from rotating with respect to the main body 100. Therefore, the second notch 3111, into which the end of the second adjusting part 420 can be inserted, is provided on the second rotating post 311, and the resistance between the second adjusting part 420 and the second rotating post 311 can be further increased, thereby more stably restricting the second rotating post 311 from continuing to rotate.
It should be noted that the number of the second grooves 3111 may be two, three, four, etc. When the number of the second grooves 3111 is two, after the adjustable adjusting mechanism 300 is rotated 180 ° with respect to the main body 100, the second adjusting piece 420 is inserted into the second groove 3111 to fix the adjusting mechanism 300 with respect to the main body 100; when the number of the second grooves 3111 is three, after the adjustable adjustment mechanism 300 is rotated 120 ° with respect to the main body 100, the second adjustment piece 420 is inserted into the second groove 3111 to fix the adjustment mechanism 300 with respect to the main body 100; when the number of the second grooves 3111 is four, after the adjustable adjustment mechanism 300 is rotated by 90 ° with respect to the main body 100, the second adjustment piece 420 is inserted into the second groove 3111 to fix the adjustment mechanism 300 with respect to the main body 100, and so on.
In addition, in the present application, the first adjustment member 410 and the second adjustment member 420 are both standard members: self-locking spring positioning pin. The positioning pin is screwed with the thread on the main body 100 through the thread of the positioning pin, and the middle rod is stretched only by pulling the handle of the positioning pin with fingers, so that the clamping mechanism 200 and the adjusting mechanism 300 are limited.
It is understood that, as shown in fig. 1 and 3, during the process of inserting the first rotating column 211 into the first through hole 111 to be rotatably connected with the first end 110, a bushing 510, a washer 520, and the like may be disposed at the outer circumference of the first rotating column 211 to avoid direct friction between the first rotating column 211 and the inner wall of the first through hole 111, thereby facilitating to reduce the wear of the first rotating column 211 and the main body 100.
