In the present utility model, unless explicitly specified and limited otherwise, the terms "mounted," "connected," "secured," and the like are to be construed broadly, and may be, for example, fixedly connected, detachably connected, or integrally formed; may be mechanically connected, may be electrically connected or may communicate with each other; can be directly connected or indirectly connected through an intermediate medium, and can be communicated with the inside of two elements or the interaction relationship of the two elements. The specific meaning of the above terms in the present utility model can be understood by those of ordinary skill in the art according to the specific circumstances.
Referring to fig. 1, the negative pressure suction apparatus of the present utility model includes a negative pressure suction device 100 and a drainage device 200, the negative pressure suction device 100 includes a vacuum pump capable of drawing negative pressure, and the drainage device 200 is in communication with the negative pressure suction device 100. Thus, when the vacuum pump of the negative pressure suction device 100 is used for evacuating, the suction medium in the treatment interface, such as gas or liquid in the stomach or chest, is sucked out under the negative pressure formed by the vacuum pump and is introduced into the drainage device 200, so as to achieve the purpose of sewage disposal and purification.
In the long-term use process of the negative pressure suction apparatus, if the drainage device 200 is directly connected to and communicated with the negative pressure suction device 100, the liquid in the suction medium, such as a small amount of micro-water droplets in the sucked gas or a small amount of sucked liquid, may be directly brought into the negative pressure suction device 100, and accumulated time may affect the working performance of the negative pressure suction device 100, especially the vacuum pump, so that the working efficiency of the negative pressure suction device 100 is low or the negative pressure suction device 100 cannot work normally, thereby seriously affecting the operation of the negative pressure suction device 100 until the negative pressure suction device 100 is damaged. The liquid suction device 300 for the negative pressure suction apparatus of the present utility model can effectively avoid the above-mentioned situation, effectively avoid liquid from entering the negative pressure suction device 100, and ensure the working performance and the operation reliability of the negative pressure suction device 100.
The suction device 300 of the present utility model will be described in detail below with reference to a preferred embodiment of the suction device 300 for a negative pressure suction apparatus of the present utility model.
Preferably, in conjunction with fig. 1 and 2, the suction device 300 for a negative pressure suction apparatus of the present utility model includes a flow-through connector 10 and a wick 20.
Preferably, a flow chamber 101 is formed in the flow joint 10, and two ends of the flow joint 10 are provided with a flow outlet 102 and a flow inlet 103 which are communicated with the flow chamber 101. The flow-through outlet 102 is adapted to communicate with the negative pressure suction device 100.
Thus, before the negative pressure suction device 100 is operated to suction the suction medium, the circulation outlet 102 of the circulation joint 10 is connected to and communicates with the negative pressure suction device 100, and then the vacuum pump that drives the negative pressure suction device 100 is evacuated to form negative pressure, so that when the negative pressure suction device 100 sucks the suction medium at negative pressure, the suction medium inevitably flows into the circulation inlet 103 of the circulation joint 10 provided before the negative pressure suction device 100, and then flows from the circulation inlet 103 in a direction toward the circulation outlet 102 and the negative pressure suction device 100.
The wick 20 is disposed within the flow-through chamber 101 for absorbing a liquid. Thus, when the suction medium flows from the circulation inlet 103 to the circulation outlet 102 and the negative pressure suction device 100, the liquid in the suction medium is absorbed by the wick 20.
Therefore, the liquid suction device 300 of the present utility model can prevent liquid from entering the negative pressure suction device 100, and can ensure the operation performance and operation reliability of the negative pressure suction device 100, and has a simple structure and low cost.
According to some preferred embodiments of the present utility model, in combination with fig. 2 and 3, the flow-through connector 10 comprises a first pair of connectors 11 and a second pair of connectors 12. Wherein one end of the first pair of connectors 11 forms the flow-through outlet 102. The second butt joint 12 has one end forming the flow inlet 103, at least one other end of the first butt joint 11 and the second butt joint 12 has an axially extending butt joint groove 104, and the other end of the first butt joint 11 and the other end of the second butt joint 12 are in sealing butt joint to close the butt joint groove 104 to form the flow chamber 101.
That is, when assembling the liquid absorbing device 300, the liquid absorbing core 20 may be put into the docking groove 104, and then the first docking head 11 and the second docking head 12 may be in a sealed docking connection, so as to seal and close the opening of the docking groove 104, thereby assembling the liquid absorbing device 300, which is convenient to assemble, and can ensure that the suction medium is not leaked.
Specifically, the first butt joint 11 and the second butt joint 12 are in sealing connection through adhesive bonding, so that the assembly is convenient, and the sealing effect is good.
Further, referring to fig. 2 and 3, the other ends of the first abutment 11 and the second abutment 12 form the abutment recess 104, and the openings of the two abutment recesses 104 abut against each other to form the circulation chamber 101.
As a result, the volume of the flow chamber 101 formed in the flow joint 10 is large, and a large amount of the wick 20 can be contained, so that the liquid in the suction medium can be sufficiently absorbed.
Of course, it is understood that the present utility model may be implemented such that only the first abutment 11 has the abutment recess 104, or only the second abutment 12 has the abutment recess 104. When the other ends of the first abutment 11 and the second abutment 12 form the abutment recess 104, the openings of the two abutment recesses 104 may be equal or unequal, so long as a closed circulation cavity 101 can be formed by the abutment recesses 104.
Specifically, the portion of the first abutment 11 having the abutment recess 104 has a larger diameter than the portion having the flow-through outlet 102. The portion of the second abutment 12 having the abutment recess 104 has a larger diameter than the portion having the flow-through inlet 103. Thus, the flow-through connector 10 saves material and facilitates connection of the flow-through connector 10 to other devices.
According to some preferred embodiments of the present utility model, referring to fig. 1 and 2, the suction device 300 for a negative pressure suction apparatus includes a flexible tube 30, and one end of the flexible tube 30 is in communication with the flow inlet 103, and the other end is in communication with the drainage device 200 adapted to introduce the suction medium.
In other words, when the negative pressure suction apparatus is used, the drainage device 200 adapted to introduce the suction medium, the flexible tube 30, the flow joint 10 and the negative pressure suction device 100 are connected and communicated in this order. Thus, when the vacuum pump of the negative pressure suction device 100 is used for evacuating, the suction medium in the treatment interface, such as gas or liquid in the stomach or chest, is sucked out under the negative pressure formed by the vacuum pump and is introduced into the drainage device 200, so as to achieve the purpose of sewage disposal and purification. Meanwhile, since the flexible tube 30 has flexibility and can be bent, the flexible tube 30 can ensure that the liquid suction device 300 and the drainage device 200 are smoothly connected, and the flexible tube is flexible and convenient to use and convenient to arrange.
In particular, the flexible tube 30 may be a plastic hose, which has low cost, light weight and convenient assembly.
Further, with reference to fig. 2, the second butt joint 12 has an insertion portion 121 adapted to be inserted into the flexible pipe 30, the insertion portion 121 is formed at an end thereof with the flow inlet 103, and an outer diameter of the insertion portion 121 is gradually reduced in a direction approaching the flow inlet 103. Thereby, assembly between the flexible tube 30 and the second pair of joints 12 is facilitated.
According to some preferred embodiments of the present utility model, the wick 20 is made of a liquid-absorbing material, more preferably a water-absorbing material, and the wick 20 has a vent structure.
In this way, the liquid suction device 300 of the present utility model can not only ensure the smooth performance of the negative pressure vacuum process of the negative pressure suction device 100, but also fully absorb the liquid.
Preferably, the wick 20 may be dry cotton, which is inexpensive.
The utility model provides a negative pressure suction device, which comprises a negative pressure suction device 100, a drainage device 200 and a liquid suction device 300 as described above, wherein the circulation outlet 102 and the circulation inlet 103 of the liquid suction device 300 are respectively communicated with the negative pressure suction device 100 and the drainage device 200, so that the suction medium is guided into the drainage device 200 by generating negative pressure by the negative pressure suction device 100, and the purpose of sucking gas or liquid and the like is realized.
In particular, the drainage device 200 may include a negative pressure aspiration needle and a drainage tube assembly coupled to and in communication with the negative pressure aspiration needle. The negative pressure suction device 100 may include a negative pressure pumping element such as a vacuum pump.
