Description

Technical Field

[0001] The invention relates to the technical field of medical infusion, and in particular to a high-precision heatable medical infusion pump. Background Art

[0002] Infusion pumps are usually mechanical or electronic control devices that control the infusion rate by acting on the infusion catheter. They are often used in situations where the infusion volume and drug dosage need to be strictly controlled, such as when using pressor drugs, antiarrhythmic drugs, intravenous infusion for infants or intravenous anesthesia.

[0003] In the process of detecting bubbles in the infusion tube of the existing infusion pump, the detection accuracy of the bubbles in the infusion tube is poor due to the poor stability of the infusion tube.

[0004] For example, the infusion pump provided by the authorization announcement number CN114470404B, considering that when the bubble detection device detects whether there are bubbles in the infusion tube, if the infusion pump body vibrates and drives the infusion tube to vibrate, or the infusion tube itself changes position, the part detected by the ultrasonic chip changes irregularly, and the detection result will be affected. It also includes an ultrasonic pressure head, which includes a connecting part and a pressing part connected to the connecting part, and the pressing part presses the infusion tube so that the infusion tube abuts against the inner wall of the groove; the pressing part includes an I-shaped protrusion, and the middle part of the I-shaped protrusion is parallel to the groove, and the ultrasonic probe is provided with an avoidance groove that adapts to the two end parts of the I-shaped protrusion, and the avoidance groove is connected to the groove; the two end parts of the I-shaped protrusion increase the force application range of the pressing part in the width direction of the infusion tube, and reduce the possibility of the infusion tube being separated from the force center.

[0005] It has a major drawback: when the I-shaped protrusion of the pressing part is used to press the infusion tube to improve the effect of fixing the position of the infusion tube, the contact area between the I-shaped protrusion of the pressing part and the infusion tube is small, and the fixing effect is poor when fitting. Summary of the invention

A limiting groove is provided on one side of the limiting block, and the limiting groove with an arc-shaped cross-section is tightly attached to the outer wall of the infusion tube, thereby increasing the contact area between the two, thereby further improving the fixing effect of the infusion tube, preventing the infusion tube from being displaced due to vibration or external force during the detection process, and ensuring the accuracy of the ultrasonic chip in bubble detection.

[0058] One or more technical solutions provided in the embodiments of the present application have at least the following technical effects or advantages:

[0060] Secondly, since the infusion tube has a certain elasticity, the infusion tube bent in the opening of the storage block can be clamped inside, and when the limit block and the limit groove do not interfere with the infusion tube, the infusion tube can be effectively prevented from falling off, thereby improving the installation effect; and since the storage block is wavy as a whole, when the infusion tube is pulled, the friction force can be increased, the fixing effect of the infusion tube can be improved, thereby improving the accuracy of bubble detection; and when the bubbles are transported in the bent wavy infusion tube, the movement trajectory can be continuously changed, so that the bubbles located on the side of the infusion tube are transported to the middle position, thereby improving the sensitivity and accuracy of detection;

[0061] Thirdly, the laminating film after being squeezed can continuously apply pressure to the infusion tube, thereby improving the stabilizing effect on the position of the infusion tube and improving the accuracy and stability of bubble detection; when the infusion tube is pulled externally, the deformation of the laminating film can absorb part of the pulling force and reduce the influence of the pulling on the fixed position of the infusion tube; when the disassembly shell is removed, due to the elastic force of the laminating film when it is reset, it will continuously resist the infusion tube, so that the infusion tube will be located in the U-shaped opening of the storage block and will not move with the movement of the limiting groove, thereby improving the efficiency of subsequent disassembly of the infusion tube; and when the disassembly shell is removed, the deformed laminating film will resist the infusion tube when it is reset and exert a force to move away, thereby improving the efficiency of removing the disassembly shell;

[0062] Fourthly, since the expansion cavity formed by the blocking film, the bonding film and the limiting groove can be expanded by inflation, the expanded bonding film can continuously press the infusion tube, thereby further improving the fixing effect of the position of the infusion tube and improving the accuracy of detecting bubbles; and when the disassembly shell is removed, the air pump works, and the expansion cavity formed by the blocking film, the bonding film and the limiting groove continues to expand again, which can continuously resist the infusion tube and the storage block, so that the disassembly shell is continuously moved away from the shell body for disassembly, thereby further improving the disassembly efficiency of the disassembly shell.

[0096] The limiting block 240 and the limiting groove 241 are both in a wave shape that matches the U-shaped opening of the storage block 440.

[0097] When installing and placing the infusion tube 170, the infusion tube 170 is placed in the opening of the wavy storage block 440, and is placed in both the peristaltic groove 421 and the heating groove 411. Since the infusion tube 170 has a certain elasticity, the infusion tube 170 bent in the opening of the storage block 440 can be engaged inside; when the shell 130 is disassembled to enter the shell body 120, the limit block 240 is slidably set in the U-shaped opening of the storage block 440, and the limit groove 241 contacts the infusion tube 170 located in the U-shaped opening of the storage block 440.

[0098] Since the infusion tube 170 has a certain elasticity, the infusion tube 170 bent in the opening of the storage block 440 can be engaged inside, and when the limit block 240 and the limit groove 241 do not interfere with the infusion tube 170, the infusion tube 170 can be effectively prevented from falling off, thereby improving the installation effect; and since the storage block 440 is wavy as a whole, when the infusion tube 170 is pulled, the friction force can be increased, the fixing effect of the infusion tube 170 can be improved, thereby improving the accuracy of bubble detection; and when the bubbles are transported in the bent wavy infusion tube 170, the movement trajectory can be continuously changed, so that the bubbles located on the side of the infusion tube 170 are transported to the middle position, thereby improving the sensitivity and accuracy of detection.

[0099] Embodiment 3: When the embodiment 2 is in use, the position of the infusion tube 170 is limited by the storage block 440 with a wavy structure and the wavy limiting block 240 and the limiting groove 241. However, when in use, the fixing effect is poor due to the friction between the infusion tube 170 and the inner wall of the opening of the limiting groove 241 and the storage block 440. Based on this, the solution of the embodiment 2 is improved, such as Fig.14 As shown:

[0100] Also included is an auxiliary component 500, wherein the auxiliary component 500 includes a laminating film 510;

[0101] The laminating film 510 is in a wave shape that matches the limiting groove 241;

[0102] The laminating film 510 is fixed in the limiting groove 241;

[0103] When the disassembly shell 130 is slidably disposed in the groove of the housing 120 , the laminating film 510 in the limiting groove 241 contacts the infusion tube 170 ;

[0104] When the laminating film 510 fixes the position of the infusion tube 170 , the laminating film 510 is continuously deformed by force to fit the surface of the infusion tube 170 .

[0105] When in use, when the position of the infusion tube 170 is restricted by the contact between the limit block 240 and the limit groove 241 and the infusion tube 170, the infusion tube 170 first contacts the bonding film 510, and when the limit block 240 and the limit groove 241 continue to approach and contact the infusion tube 170, the bonding film 510 is deformed by the pressure of the infusion tube 170, and the deformed bonding film 510 continues to contact the infusion tube 170 to fix the position of the infusion tube 170; and when the disassembly shell 130 is removed, since the bonding film 510 continues to contact the infusion tube 170, the infusion tube 170 will be located in the U-shaped opening of the storage block 440 and will not move with the movement of the limit groove 241; and when the disassembly shell 130 is removed, the deformed bonding film 510 will contact the infusion tube 170 and exert a force to move away.

[0106] After being squeezed, the laminating film 510 can continuously apply pressure to the infusion tube 170, thereby improving the stabilizing effect on the position of the infusion tube 170 and improving the accuracy and stability of bubble detection; when the infusion tube 170 is pulled externally, the deformation of the laminating film 510 can absorb part of the pulling force and reduce the influence of the pulling on the fixed position of the infusion tube 170; when the disassembly shell 130 is removed, due to the elastic force of the laminating film 510 when it is reset, it will continuously resist the infusion tube 170, so that the infusion tube 170 is located in the U-shaped opening of the storage block 440 and will not move with the movement of the limiting groove 241, thereby improving the subsequent disassembly efficiency of the infusion tube 170; and when the disassembly shell 130 is removed, the deformed laminating film 510 will resist the infusion tube 170 when it is reset and apply a force away, thereby improving the efficiency of removing the disassembly shell 130.

[0107] Embodiment 4: When the embodiment 3 is in use, the laminating film 510 continuously applies a resisting force to the infusion tube 170, thereby fixing the infusion tube 170. However, when in use, the device can be improved to further improve the fixing effect of the infusion tube 170. Based on this, the solution of the embodiment 3 is improved, such as Figure 15-16 As shown:

[0108] The auxiliary component 500 also includes a blocking film 520 and an air pump 530; the blocking film 520 has two portions, corresponding to the two ends of the laminating film 510 in the length direction; the blocking film 520 is fixed at the two ends of the laminating film 510 in the length direction, and the blocking film 520 is fixed to the inner wall of the limiting groove 241, and the blocking film 520 blocks the two ends of the limiting groove 241 and the laminating film 510; the blocking film 520, the laminating film 510 and the limiting groove 241 form a separate expansion cavity; the air pump 530 is fixed to the lower side of the mounting plate 230; the conflicting component 200 also includes an air delivery channel One 231 and two air delivery channels 242; the mounting plate 230 is provided with an air delivery channel 1 231, the limiting block 240 is provided with an air delivery channel 2 242, and the air delivery channel 1 231 and the air delivery channel 2 242 are connected; the end of the air delivery channel 1 231 away from the air delivery channel 2 242 is connected to the output end of the air pump 530, and the end of the air delivery channel 2 242 away from the air delivery channel 1 231 is connected to the expansion cavity formed by the blocking film 520, the bonding film 510 and the limiting groove 241; when the air pump 530 is working, the bonding film 510 is inflated to expand and bond to the infusion tube 170 or deflated and retracted.

[0109] During use, when the limiting block 240 and the limiting groove 241 are in contact with the infusion tube 170, the air pump 530 works to expand the expansion cavity formed by the blocking film 520, the bonding film 510 and the limiting groove 241, and the expanded bonding film 510 continuously presses the infusion tube 170; and when the disassembly shell 130 needs to be removed, the air pump 530 works to expand the expansion cavity formed by the blocking film 520, the bonding film 510 and the limiting groove 241 continuously expands, continuously resists the infusion tube 170 and the storage block 440, and makes the disassembly shell 130 continuously move away from the shell body 120 for disassembly; after the disassembly shell 130 is completely disassembled, the expansion cavity formed by the blocking film 520, the bonding film 510 and the limiting groove 241 is deflated to facilitate the next work.

[0110] Since the expansion cavity formed by the blocking film 520, the bonding film 510 and the limiting groove 241 can be expanded by inflation, the expanded bonding film 510 can continuously press the infusion tube 170, thereby further improving the fixing effect of the position of the infusion tube 170 and improving the accuracy of detecting bubbles; and when removing the disassembly shell 130, the air pump 530 works, and the expansion cavity formed by the blocking film 520, the bonding film 510 and the limiting groove 241 continues to expand again, which can continuously resist the infusion tube 170 and the storage block 440, so that the disassembly shell 130 is continuously moved away from the shell body 120 for disassembly, thereby further improving the disassembly efficiency of the disassembly shell 130.

[0111] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
