Description

Technical Field

[0001] The utility model relates to the technical field of ultrasonic emulsification surgical auxiliary equipment, in particular to a non-directional flushing pipeline of a medical peristaltic pump. Background Art

[0002] Ultrasonic emulsification surgery is now a conventional treatment method for cataracts. Compared with the traditional large-incision whole cataract extraction surgery, ultrasonic emulsification is a minimally invasive surgery. A small incision of about 2-3 mm is made on the edge of the cornea. Through this small incision, an ultrasonic emulsification needle is inserted to crush the cloudy lens and cortex into a milky substance. Then, with the help of a suction and perfusion system, the milky substance is aspirated while keeping the anterior chamber full. Then, an artificial lens is implanted to enable the patient to see again.

[0003] During the ultrasonic emulsification surgery, when performing steps such as flushing, disinfection, and perfusion, various liquids need to be transported to the surgical site, such as disinfectant solution, perfusion solution, etc. The traditional liquid transportation method is usually carried out by means of a peristaltic pump cooperating with a pump tube. For the peristaltic pump used to transport liquids in ultrasonic emulsification surgery, due to the limitations of the medical environment, the peristaltic pump used is usually unidirectional transportation.

[0004] As a pump that can transport fluids, the peristaltic pump has high cleanliness because the fluid only contacts the pump tube and does not contact the pump body during use. At the same time, its repetition accuracy and stability accuracy are relatively high. It also has good self-priming ability, can run idle, and prevent backflow, so it is widely used in the pharmaceutical industry.

[0005] In the prior art, for a peristaltic pump, such as a hose fixing structure and a peristaltic pump including the hose fixing structure disclosed in a Chinese patent with the publication number CN112343805A, the delivery hose is detachably installed on the peristaltic pump through the hose fixing structure.

[0006] Another example is a quick-install peristaltic pump disclosed in a Chinese patent with the publication number CN214330859U, which realizes the detachable installation of the hose through a locking mechanism and a locking groove mechanism.

[0007] As can be seen from the above prior art, most traditional pump tubes adopt a detachable installation method for more convenient operation and use. The two ends connected to the pump tube are respectively:

[0008] A liquid supply pipe for supplying liquid, such as a medical plastic pipe (with a needle tip) with the needle tip inserted into a physiological saline bottle, etc.;

[0009] A drain pipe for draining liquid, such as a medical plastic pipe connected to a flushing (draining) device, etc.;

[0010] These two pipelines for transporting liquids are usually fixed on the corresponding equipment during use, and then the pump tube is disassembled and assembled for replacement.

[0011] However, the above technical solution at least has the following defects. Since the peristaltic pump for unidirectional conveying has a fixed liquid conveying direction, and the existing pump tubes are usually single flexible hoses (the two ends of the hoses are also connected to other pipelines), it is necessary to clarify the pipeline flow direction when installing the pump tube, so that medical staff need to spend time and effort to accurately identify the installation direction to ensure that the input direction and output direction of the pump tube are consistent with the liquid conveying direction of the peristaltic pump. Especially when replacing and loading the pump tube, since other pipelines connected to the pump tube are all installed, the installation of the pump tube is not only cumbersome, there is a safety hazard of being installed in the wrong direction, reducing work efficiency, but also it is easy to cause the liquid to be difficult to convey in time due to the installation error of the pump tube, affecting the smooth progress of the operation, and the use limitation is relatively large.

[0057] The following further describes the specific embodiments of the present invention in conjunction with the accompanying drawings, but it should not be construed as a limitation to the present invention. Without departing from the spirit and essence of the present invention, any modification or replacement made to the methods, steps or conditions of the present invention shall fall within the scope of the present invention.

[0058] Provided by Figures 1 to 7 On the one hand, some embodiments of the present invention relate to a peristaltic pump, including the non-directional flushing pipeline of the medical peristaltic pump described below. Among them, the peristaltic pump further includes a fixing assembly 5, and the fixing assembly 5 is used for detachably installing and clamping the installation part 1012 of the power pipe fitting 101.

[0059] In these embodiments, as Figure 7 shown, the installation part 1012 of the clamping power pipe fitting 101 is installed on the peristaltic pump through the fixing assembly 5, and installing and clamping the power pipe fitting 101 in a detachable manner is more convenient for flexible use.

[0060] Among them, the mechanical structure and working principle for the detachable installation of the clamping power pipe fitting 101 through the fixing assembly 5 are all prior arts, so they will not be elaborated herein. Reference can be made to a quick-install peristaltic pump disclosed in a Chinese patent with the publication number CN214330859U, or a hose fixing structure and a peristaltic pump including the hose fixing structure disclosed in a Chinese patent with the publication number CN112343805A.

[0061] Provided by Figures 1 to 7 On the other hand, some embodiments of the present invention relate to a non-directional flushing pipeline of a medical peristaltic pump, including:

[0062] The first flexible pipeline assembly 1, the first flexible pipeline assembly 1 includes a clamping power pipe fitting 101 and a first valve group 102. The clamping power pipe fitting 101 is used to convey liquid along the liquid inlet pipe fitting 103 to the liquid outlet pipe fitting 104. The clamping power pipe fitting 101 is successively connected and composed of an input part 1011, a mounting part 1012, and an output part 1013. The first valve group 102 is used to control the connection or disconnection between the input part 1011 and the liquid inlet pipe fitting 103;

[0063] The second flexible pipeline assembly 2, the second flexible pipeline assembly 2 includes a first guiding branch pipe fitting 201, a second guiding branch pipe fitting 202, and a second valve group 203. The first guiding branch pipe fitting 201 is used to connect the liquid inlet pipe fitting 103 and the output part 1013. The second guiding branch pipe fitting 202 is used to connect the input part 1011 and the liquid outlet pipe fitting 104. The second valve group 203 is used to control the connection or disconnection of the first guiding branch pipe fitting 201.

[0064] In these embodiments, as Figure 1 shown, the clamping power pipe fitting 101 is integrally formed by the input part 1011, the mounting part 1012, and the output part 1013. The input end of the first valve group 102 is fixedly installed with the liquid inlet pipe fitting 103, the output end of the first valve group 102 is fixedly installed with the input part 1011, and the output part 1013 is fixedly installed with the liquid outlet pipe fitting 104.

[0065] The input end of the first guiding branch pipe fitting 201 is fixedly installed with the liquid inlet pipe fitting 103, the output end of the first guiding branch pipe fitting 201 is fixedly installed with the output part 1013. The input end of the second guiding branch pipe fitting 202 is fixedly installed with the input part 1011, the output end of the second guiding branch pipe fitting 202 is fixedly installed with the liquid outlet pipe fitting 104, and the second valve group 203 is fixedly installed on the first guiding branch pipe fitting 201 to restrict the liquid to only flow from the liquid inlet pipe fitting 103 to the output part 1013.

[0066] When in use, by installing the mounting part 1012 on the peristaltic pump (at this time, the flow direction of the liquid conveyed by the pipeline is consistent with the conveying direction of the peristaltic pump), at this time, driven by the peristaltic pump, the first valve group 102 is in an open state, and the second valve group 203 is in a closed state, so that the liquid flows along the liquid inlet pipe fitting 103 through the clamping power pipe fitting 101 and is conveyed to the liquid outlet pipe fitting 104 (as Figure 1 shown by the solid arrow in the figure), thereby realizing the stable conveying of the liquid.

[0067] When the installation part 1012 is installed (in reverse) on the peristaltic pump (at this time, the flow direction of the liquid in the pipeline is opposite to the conveying direction of the peristaltic pump), under the drive of the peristaltic pump, the first valve group 102 is in the closed state, and the second valve group 203 is in the open state, so that the liquid first flows from the liquid inlet pipe fitting 103 to the first guiding branch pipe fitting 201, then from the first guiding branch pipe fitting 201 to the output part 1013, flows through the installation part 1012 of the peristaltic pump to the input part 1011, then from the input part 1011 to the second guiding branch pipe fitting 202, and finally from the second guiding branch pipe fitting 202 to the liquid outlet pipe fitting 104 (as Figure 1 shown by the dotted arrow in

[0068] ), thus realizing the stable conveying of the liquid. By installing the clamping power pipe fitting 101 in any direction, it can ensure that the liquid is conveyed from the liquid inlet pipe fitting 103 to the liquid outlet pipe fitting 104, thus avoiding the need for medical staff to spend time and effort to accurately identify the installation direction and the need to laboriously clarify the pipeline flow direction. No matter how it is installed, it can ensure that the input direction and output direction of the pump pipe (clamping power pipe fitting 101) are consistent with the liquid conveying direction of the peristaltic pump, greatly reducing the installation complexity of the pump pipe. Especially when replacing and loading the pump pipe, only the pump pipe itself needs to be adjusted and replaced, effectively avoiding the influence of other pipelines, thus improving the convenience of loading and unloading the pump pipe, avoiding the potential safety hazard of incorrect installation, not only being beneficial to improving the work efficiency of medical staff, but also being able to avoid the problem that the liquid is difficult to be conveyed in time due to the incorrect installation of the pump pipe, ensuring the smooth progress of the operation, effectively improving the flexible adaptability of the pump pipe and the peristaltic pump in liquid conveying, and having stronger practicability.

[0069] It should be understood that in the present utility model, the non-directional flushing pipeline of the medical peristaltic pump all adopts flexible pipes. Further preferably, the clamping power pipe fitting 101 can adopt a silicone tube and is installed in a plug-in manner through an interface. The rest of the pipelines can adopt medical plastic pipes, etc. Among them, the liquid inlet pipe fitting 103 is connected to the liquid supply pipeline (such as a plastic pipe, etc.), and the liquid outlet pipe fitting 104 is connected to the liquid discharge pipeline (such as a plastic pipe, etc.).

[0070] Further, based on the prior art, when the present utility model is in use, except that the clamping power pipe fitting 101 in the non-directional flushing pipeline of the medical peristaltic pump is installed on the peristaltic pump, the rest of the pipe fittings can be stored or fixed through a storage device or a support device. The mechanical structure and working principle of the storage device or the support device are all prior art, so they will not be elaborated in this text.

[0071] In some embodiments of the non-directional flushing pipeline of the medical peristaltic pump, the first valve group 102 includes a first one-way valve 1021, and the first one-way valve 1021 is used to restrict the liquid to only flow from the liquid inlet pipe fitting 103 to the input part 1011;

[0072] The first one-way valve 1021 is any one of a spring-loaded one-way valve, a straight-through one-way valve, a right-angle one-way valve, and a plastic diaphragm one-way valve.

[0073] In these embodiments, preferably, the first one-way valve 1021 is a spring-loaded one-way valve. The input end of the first one-way valve 1021 is fixedly installed with the liquid inlet pipe fitting 103, and the input end of the first one-way valve 1021 is fixedly installed with the input part 1011. Through the setting of the first one-way valve 1021, it can be automatically opened or closed under the drive of the peristaltic pump.

[0074] The working principle of the spring-loaded one-way valve is based on the interaction between the pressure difference and the spring force. The specific process is as follows:

[0075] Forward flow: When the medium (such as liquid or gas) invades the valve body from the inlet and the pressure is higher than the upper end connected to the valve core and the inlet, the medium will push the valve core upward and compress the spring at the same time. As the valve core opens, the fluid can enter the valve body through the valve core and flow out from the outlet.

[0076] Reverse flow: When the medium attempts to enter the valve body from the outlet (i.e., the lower position), due to the combined action of the pressure of the medium on the valve core and the spring force, the valve core will tightly close on the valve seat, preventing the fluid from flowing backward. At this time, the spring returns to its original state, pushing the valve flap back to the sealed position to ensure that the fluid cannot flow backward.

[0077] It should be understood that the mechanical structure and working principle of the first one-way valve 1021 are both prior arts, so they will not be elaborated in this text. The same applies to the one-way valves described later, so they are omitted.

[0078] In some embodiments of the non-directional flushing pipeline of the medical peristaltic pump, the first guiding branch pipe fitting 201 is composed of a first guiding-in part 2011 and a first guiding-out part 2012. The first guiding-in part 2011 is communicated with the liquid inlet pipe fitting 103, and the first guiding-out part 2012 is communicated with the output part 1013;

[0079] The second valve group 203 includes a third one-way valve 2031, and the third one-way valve 2031 is used to restrict the liquid to only flow from the first guiding-in part 2011 to the first guiding-out part 2012;

[0080] The third one-way valve 2031 is any one of a spring-loaded one-way valve, a straight-through one-way valve, a right-angle one-way valve, and a plastic diaphragm one-way valve.

[0081] In these embodiments, the input end of the first introduction part 2011 is fixedly installed with the liquid inlet pipe fitting 103, the output end of the first introduction part 2011 is fixedly installed with the input end of the third one-way valve 2031, the output end of the third one-way valve 2031 is fixedly installed with the input end of the first export part 2012, and the output end of the first export part 2012 is fixedly installed with the output part 1013. Further preferably, the third one-way valve 2031 is a spring-type one-way valve.

[0082] Through the setting of the third one-way valve 2031, driven by the peristaltic pump, the opening or closing of the third one-way valve 2031 can automatically control the on or off of the first guiding branch pipe fitting 201, and the operation is more stable and efficient.

[0083] It should be understood that the mechanical structure and working principle of the third one-way valve 2031 are both prior arts, so they will not be elaborated in this text.

The input end of the first one-way valve 1021 is fixedly installed with the liquid inlet pipe fitting 103, the output end of the first one-way valve 1021 is fixedly installed with the input part 1011, the input end of the second one-way valve 1022 is fixedly installed with the output part 1013, the output end of the second one-way valve 1022 is fixedly installed with the liquid outlet pipe fitting 104, and the output part 1013 is fixedly installed with the liquid outlet pipe fitting 104.

[0097] The input end of the first guiding branch pipe fitting 201 is fixedly installed with the liquid inlet pipe fitting 103, the output end of the first guiding branch pipe fitting 201 is fixedly installed with the output part 1013, and the input end of the third one-way valve 2031 is fixedly installed with the output end of the first guiding part 2011, and the output end of the third one-way valve 2031 is fixedly installed with the input end of the first leading-out part 2012.

[0098] The input end of the second guiding branch pipe fitting 202 is fixedly installed with the input part 1011, the output end of the second guiding branch pipe fitting 202 is fixedly installed with the liquid outlet pipe fitting 104, and the input end of the fourth one-way valve 2032 is fixedly installed with the output end of the second guiding part 2021, and the output end of the fourth one-way valve 2032 is fixedly installed with the input end of the second leading-out part 2022.

[0099] Preferably, the first one-way valve 1021, the second one-way valve 1022, the third one-way valve 2031, and the fourth one-way valve 2032 are all spring-type one-way valves.

[0100] During use, by installing the installation part 1012 on the peristaltic pump (at this time, the flow direction of the liquid in the pipeline is the same as the conveying direction of the peristaltic pump), at this time, under the drive of the peristaltic pump, the first one-way valve 1021 and the second one-way valve 1022 are both in the open state, and the third one-way valve 2031 and the fourth one-way valve 2032 are both in the closed state, so that the liquid flows along the liquid inlet pipe fitting 103 through the clamping power pipe fitting 101 and is conveyed to the liquid outlet pipe fitting 104 (as Figures 2 - 5 shown by the solid arrow in the figure), thereby realizing the stable conveying of the liquid.

[0101] When the installation part 1012 is installed (in the reverse direction) on the peristaltic pump (at this time, the flow direction of the liquid in the pipeline is opposite to the conveying direction of the peristaltic pump), at this time, under the drive of the peristaltic pump, the first one-way valve 1021 and the second one-way valve 1022 are both in the closed state, and the third one-way valve 2031 and the fourth one-way valve 2032 are both in the open state, so that the liquid first flows from the liquid inlet pipe fitting 103 to the first guiding branch pipe fitting 201, then from the first guiding branch pipe fitting 201 to the output part 1013, flows through the installation part 1012 of the peristaltic pump to the input part 1011, then from the input part 1011 to the second guiding branch pipe fitting 202, and finally from the second guiding branch pipe fitting 202 to the liquid outlet pipe fitting 104 (as Figures 2 - 5 shown by the dashed arrow in the figure), thereby realizing the stable conveying of the liquid.

[0102] Installing the clamping power pipe fitting 101 in any direction can ensure that the liquid is transported from the liquid inlet pipe fitting 103 to the liquid outlet pipe fitting 104, thus avoiding the need for medical staff to spend time and effort to accurately identify the installation direction and eliminating the need to painstakingly clarify the pipeline flow direction. No matter how it is installed, it can ensure that the input direction and output direction of the pump pipe (clamping power pipe fitting 101) are consistent with the liquid transportation direction of the peristaltic pump, greatly reducing the complexity of installing the pump pipe. Especially when replacing and loading / unloading the pump pipe, only the pump pipe itself needs to be adjusted and replaced, effectively avoiding the influence of other pipelines, thereby improving the convenience of loading and unloading the pump pipe and eliminating the potential safety hazard of incorrect installation. This not only helps to improve the work efficiency of medical staff but also avoids the problem of difficult liquid transportation caused by incorrect installation of the pump pipe, ensuring the smooth progress of the operation, effectively improving the flexible adaptability of the pump pipe and the peristaltic pump in liquid transportation, and having stronger practicability.

[0103] It should be understood that generally, the pipelines for liquid transportation (the liquid supply pipe 3 and the liquid discharge pipe 4) are fixed. For example, the liquid supply pipe 3 fixed on the physiological saline bottle is usually not removed during use after being installed on the bottle body. This is one situation. The foregoing embodiment can better solve the problem of cumbersome installation of the pump pipe when the pipeline is fixed. In addition, there is also the situation where the port pipelines (disassembling and assembling the liquid supply pipe 3 and the liquid discharge pipe 4) need to be frequently replaced. The following embodiments are to better solve the difficulties caused by frequent installation and replacement of the pipelines.

[0104] In order to further improve the flexibility of use and reduce the installation restrictions, the difference from the foregoing embodiment is as follows:

[0105] In some embodiments of the non-directional flushing pipeline of the medical peristaltic pump, the first flexible pipeline assembly 1 further includes a first sub-valve group 105, and the first sub-valve group 105 is used to control the on or off of the liquid outlet pipe fitting 104;

[0106] The first sub-valve group 105 is any one of a spring-type one-way valve, a straight-through one-way valve, a right-angle one-way valve, and a plastic diaphragm one-way valve;

[0107] The second flexible pipeline assembly 2 further includes:

[0108] A third guiding branch pipe fitting 204, which is used to connect the liquid outlet pipe fitting 104 and the first guiding branch pipe fitting 201. A first switching valve 208 is arranged on the third guiding branch pipe fitting 204;

[0109] A second switching valve 205, which is fixedly installed on the first guiding branch pipe fitting 201;

[0110] A fourth guiding branch pipe fitting 206, which is used to connect the input part 1011 and the first guiding branch pipe fitting 201;

[0111] The second auxiliary valve group 207 is used to control the connection or disconnection between the input part 1011 and the first guiding branch pipe fitting 201;

[0112] The second auxiliary valve group 207 is any one of a spring-type one-way valve, a straight-through one-way valve, a right-angle one-way valve, and a plastic diaphragm one-way valve.

[0113] In some implementation manners of the non-directional flushing pipeline of the medical peristaltic pump, the input end of the liquid inlet pipe fitting 103 is communicated with the liquid supply pipe 3, and the output end of the liquid outlet pipe fitting 104 is communicated with the liquid discharge pipe 4, or;

[0114] The input end of the liquid inlet pipe fitting 103 is communicated with the liquid discharge pipe 4, and the output end of the liquid outlet pipe fitting 104 is communicated with the liquid supply pipe 3.

[0115] In these implementation manners, as Figure 6 shown, the first auxiliary valve group 105 is preferably a spring-type one-way valve, and the first auxiliary valve group 105 is fixedly installed on the liquid outlet pipe fitting 104.

[0116] The input end of the third guiding branch pipe fitting 204 is fixedly installed with the liquid outlet pipe fitting 104, the input end of the third guiding branch pipe fitting 204 is fixedly installed with the first guiding branch pipe fitting 201, and the first switching valve 208 is fixedly installed on the third guiding branch pipe fitting 204. Preferably, the first switching valve 208 is a rotary valve-type switching valve. The second switching valve 205 is fixedly installed on the first guiding branch pipe fitting 201. Preferably, the second switching valve 205 is a rotary valve-type switching valve.

[0117] The input end of the fourth guiding branch pipe fitting 206 is fixedly installed with the input part 1011, the output end of the fourth guiding branch pipe fitting 206 is fixedly installed with the first guiding branch pipe fitting 201, and the second auxiliary valve group 207 is preferably a spring-type one-way valve, and the second auxiliary valve group 207 is fixedly installed on the fourth guiding branch pipe fitting 206.

[0118] During use, when the liquid inlet pipe fitting 103 is connected to the liquid supply end (liquid supply pipe 3) and the liquid outlet pipe fitting 104 is connected to the liquid discharge end (liquid discharge pipe 4), the first switching valve 208 is closed and the second switching valve 205 is opened. The pump tube (clamping power pipe fitting 101) of the non-directional flushing pipeline of the medical peristaltic pump of the present invention can stably transport liquid according to the foregoing use manner. When the liquid inlet pipe fitting 103 is connected to the liquid discharge end (liquid discharge pipe 4) and the liquid outlet pipe fitting 104 is connected to the liquid supply end (liquid supply pipe 3), the first switching valve 208 is opened and the second switching valve 205 is closed. The pump tube (clamping power pipe fitting 101) of the non-directional flushing pipeline of the medical peristaltic pump of the present invention can also stably transport liquid according to the foregoing use manner. The specific working principle is the same as the above principle.

[0119] On the basis of installing the clamping power pipe fitting 101 in any direction, it is also possible to install the non-directional flushing pipeline of the medical peristaltic pump in any direction (that is, the connection between the liquid inlet pipe fitting 103 and the liquid outlet pipe fitting 104 and other pipelines), so as to ensure the stable transportation of liquid, thereby further improving the flexibility of the use of the non-directional flushing pipeline of the medical peristaltic pump, being able to better meet the use requirements of pumping liquid, not only effectively improving the practicability, but also being able to greatly reduce the use limitations of the pump tube and the peristaltic pump, being more conducive to popularization and application, and providing more convenience for medical staff.

[0120] Although the present utility model has been described in detail above with general descriptions and specific embodiments, based on the present utility model, some modifications or improvements can be made to it, which are obvious to those skilled in the art. Therefore, these modifications or improvements made without departing from the spirit of the present utility model all fall within the scope of protection required by the present utility model.
