Description

Technical Field

[0001] This utility model relates to the field of medical equipment, specifically a medical multifunctional pump device. Background Technology

[0002] In fluid dynamics technology, high-pressure pumps are one of the core components of medical fluid dynamic systems, and commonly used standard parts such as plunger pumps are often employed. In medical high-pressure pumps, when liquid enters the plunger pump for pressurization, the plunger chamber is equipped with an inlet channel and an outlet channel. Through the reciprocating motion of the piston, a continuous flow of high-pressure water is pumped out.

[0003] Existing pressure pump systems consist of a pump head, a main unit, a single-function foot pedal, and an electrosurgical unit. The pump head consumables include a piston, a piston chamber, an inlet channel, and an outlet channel. The inlet and outlet channels are connected to the piston chamber via a one-way valve. When the pump and the drive unit within the main unit reciprocate, the pump consumable outlet, in conjunction with the distal end of the electrosurgical unit, can achieve high-pressure liquid output. However, existing technology has several areas for improvement, such as: 1. Existing pump heads only have one outlet port, providing either high-pressure or low-pressure flushing water output; switching between these two states requires instrument exchange; 2. Currently, when medical staff use peristaltic pumps for flushing during ESD surgery, they need to switch operating devices and foot pedals, causing operational inconvenience; 3. Medical staff have complained about the excessive output pressure of peristaltic pumps, and there is also a need for low-pressure, low-flow flushing during gastrointestinal endoscopy. Therefore, this invention proposes a multi-functional medical pump device to solve the above-mentioned problems in the existing technology. Utility Model Content

[0032] The present invention will now be described in further detail with reference to the accompanying drawings.

[0033] A medical multifunctional pump device, characterized in that it comprises:

[0034] Pump head 1, the pump head 1 includes piston chamber 2, piston disposed inside piston chamber 2, liquid inlet channel 4 communicating with piston chamber 2 and liquid outlet channel 5 communicating with piston chamber 2, the liquid inlet channel 4 is connected to a plurality of liquid inlet ports 6, and the liquid outlet channel 5 is provided with a plurality of liquid outlet ports 7 in parallel.

[0035] A directional valve 8 can be installed at the connection between the inlet port 6 and the inlet channel 4, and at the connection between the outlet port 7 and the outlet channel 5, to control the opening and closing of the corresponding inlet port 6 and outlet port 7.

[0036] The liquid outlet port 7 includes liquid outlet port one 701 and liquid outlet port two 702.

[0037] The liquid outlet port 7 also includes a liquid outlet port 3 703.

[0038] The valve core of the directional valve 8 is a T-shaped cylinder, and a liquid channel 801 is formed in the region away from the T-shaped head of the directional valve 8, allowing liquid to pass through. The diameter of the sealing surface and the depth of the liquid channel of the directional valve 8 can be adjusted according to the size of the liquid outlet channel, and a sealing surface 802 is also provided. It also includes a piston rod 3, one end of which is connected to a drive device, and the other end of which is connected to the piston rod 3 away from the drive device. The drive device drives the piston rod to cause the piston to reciprocate within the piston chamber 2.

[0039] It also includes a control component, which controls the state switching of the directional valve 8 to control the opening and closing of the outlet port 7 corresponding to each directional valve 8.

[0040] The control component is a multi-functional foot pedal used for switching the state of the directional valve, thereby enabling the medical multi-functional pump to operate in different modes. The control component is also a hand-held button used for switching the state of the directional valve, thereby enabling the medical multi-functional pump to operate in different modes.

[0041] This utility model provides a medical multifunctional pump device. When in use, it is equipped with an existing control host and matching instruments. This device has multiple liquid output ports for selection, especially high-pressure output and flushing function. The two functions are controlled by foot pedal, button and one or more directional valves 8. Medical staff do not need to manually switch the operating equipment during operation. The foot pedal switch integrates the function switch for flushing and raising, which can be directly controlled by foot, saving operation time. At the same time, medical staff can also use their hands to press the control button to control the liquid output.

[0042] The liquid inlet channel 4 of this invention is connected to several liquid inlet ports 6, and the liquid outlet channel 5 is provided with several liquid outlet ports 7 in parallel. The specific number of liquid inlet ports 6 and liquid outlet ports 7 can be set as needed. For example, one inlet and multiple outlet means that one liquid inlet port 6 is set on the liquid inlet channel 4 and multiple liquid outlet ports 7 are set on the liquid outlet channel 5; multiple inlet and one outlet means that multiple liquid inlet ports 6 are set on the liquid inlet channel 4 and one liquid outlet port 7 is set on the liquid outlet channel 5; multiple inlet and multiple outlet means that multiple liquid inlet ports 6 are set on the liquid inlet channel 4 and multiple liquid outlet ports 7 are set on the liquid outlet channel 5; the specific number is determined according to the actual use requirements.

[0043] Example 1: One-in-many-out example:

[0044] like Figure 2 and Figure 3 As shown, in a one-inlet-multiple-outlet configuration, the inlet channel 4 is equipped with one inlet port 6, and the outlet channel 5 is equipped with two outlet ports 7, namely outlet port one 701 and outlet port two 702. Outlet port one 701 is close to the inlet port 6, and the connection between outlet port one 701 and outlet channel 5 is connected to inlet channel 4. A directional valve 8 is installed at the connection between outlet port one 701 and outlet channel 5. The pipeline connected to outlet port one 701 serves as a flushing outlet pipeline, and the pipeline connected to outlet port two 702 serves as a raised outlet channel.

[0045] Rotate the directional valve 8 to the outlet. Figure 2As shown, the connection between outlet port 1 701 and outlet channel 5 is not connected to inlet channel 4. Both outlet port 1 701 and outlet port 2 702 are connected to outlet channel 5. At this time, since outlet port 2 702 is a small-diameter raised outlet channel and serves as a high-pressure output interface, the connected equipment does not work due to the high-pressure nature of outlet port 2 702. Meanwhile, outlet port 1 701 is a large-diameter flushing channel. The liquid from outlet channel 5 mainly flows out through outlet port 1 701 to achieve the flushing mode.

[0046] Rotate the directional valve 8 to the outlet. Figure 3 As shown in the diagram, the connection between the liquid outlet port 1 701 and the liquid outlet channel 5 is not connected to the liquid inlet channel 4, and the liquid outlet port 1 701 is also not connected to the liquid outlet channel 5. Only the liquid outlet port 2 702 is connected to the liquid outlet channel 5, and the liquid is discharged only from the liquid outlet port 2 702. This can be used as a high-pressure output bulging liquid outlet mode.

[0047] In practical applications, the number of liquid outlet ports 7 can be increased to meet usage requirements, such as... Figure 5 and Figure 6 As shown, another outlet port 703 is set above outlet port 702. A directional valve 8 is set at the connection between outlet port 703 and outlet port 702. The directional valve 8 controls the on / off state of outlet port 703 and outlet port 702.

[0048] Example 2: Multiple-input-one-output example

[0049] like Figure 8 As shown, it is a multi-inlet, one-outlet configuration, with multiple inlet ports 6 on the inlet channel 4 and one outlet port 7 on the outlet channel 5.

[0050] Example 3: Multiple-input multiple-output example

[0051] like Figure 9 As shown, it is a multi-inlet and multi-outlet type, with multiple inlet ports 6 on the inlet channel 4 and multiple outlet ports 7 on the outlet channel 5.

[0052] Example 4: Setting the tilt angle of a portion of the liquid outlet channel

[0053] To adapt to usage requirements, it can be as follows: Figure 4 , Figure 6 As shown, the outlet channels connected to several outlet ports after outlet port 701 can be arranged at an angle.

[0054] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
