General anesthesia is divided into intravenous general anesthesia and oral tracheal intubation general anesthesia, so that a patient is completely free of pain and consciousness and touch under an anesthesia state, and the anesthesia mode is suitable for large surgery or minimally invasive endoscopic surgery and requires important organs such as heart, lung, brain and the like of the patient to have no serious dysfunction.
In the conventional liposuction operation, general anesthesia is generally employed. However, during liposuction, general anesthesia can lead to complex overload of systemic circulation in patients in unconscious state, resulting in excessive left atrial pressure, elevated central venous pressure (over 36cc of body fluid), pulmonary hydrops, pulmonary edema MODS, progressive result ARDS and thus pulmonary edema, cerebral edema, brain death, and acute complications such as unconsciousness, no feedback under any stimulus including pain stimulus, damage and rupture of neurovascular muscle under no stress state, and thus hemorrhage, and pulmonary and cerebral embolism due to fat particles.
To avoid this, local anesthesia may be used instead of general anesthesia in the liposuction hand. Local anesthesia uses local anesthetic drugs to temporarily block the transmission of painful nerve impulses in the surgical field, leaving the patient free of pain, but with sensation and feel, and the patient in a conscious state, possibly with the assistance of a physician. Compared with the general anesthesia mode, the local anesthesia mode can be repeatedly administered under the safe dosage, thereby prolonging the anesthesia time and achieving the advantages of quick effect, quick metabolism, small total toxic and side use and the like.

The infusion line in the present embodiment may be constituted by a first hose 20 connected between the liquid collecting device 10 and the driving device 30, and a second hose 40 connected between the driving device 30 and the flow dividing device 50. Of course, in practical applications, the first hose 20 and the second hose 40 may be formed by the same hose.
The liquid collecting device 10 in this embodiment includes a liquid collecting cavity for accommodating the swelling liquid, the shunt device 50 includes at least one liquid inlet, a plurality of liquid outlets, and an infusion cavity for communicating the liquid inlet and the liquid outlet, and the swelling liquid in the liquid collecting device 10 is sent to the liquid inlet of the shunt device 50 through the infusion line and the driving device 30. Specifically, the number of hoses 60 and needles 70 may be the same as the number of outlets of the shunt device 50, respectively, such that each needle 70 is connected to one outlet of the shunt device 50 by one hose 60, and the tumescent fluid from the fluid collecting device 10 in the shunt device 50 is injected into the subcutaneous fat layer by the needles 70 under the pressure generated by the driving device 30 (when the needles 70 are inserted into the subcutaneous fat layer).
The hose 60 may be made of PU material, and the needle 70 may be a porous needle (i.e. a plurality of water outlets are formed at the end of the needle).
When the infusion apparatus for liposuction tumefaction anesthesia of the present embodiment is used for local anesthesia of an operator, after the sterilized shunt device 50, the hose 60, the needle 70 and the infusion line are prepared, the needle 70 is connected to the hose 60, and then the other ends of the hose 60 connected with the needle 70 are respectively connected to the liquid outlet of the shunt device 50. When the peristaltic pump is used as the driving device 30, the infusion line may be formed of a silicone tube. One end of the liquid inlet of the shunt device 50 connected with the hose 60 is connected with one end of a silicone tube of the peristaltic pump, the other end of the silicone tube is connected to the configured swelling liquid of the liquid collecting device 10, and then the silicone tube is mounted on the peristaltic pump. The prepared liposuction part is injected with an opening for anesthesia and breach, a plurality of needles 70 are uniformly inserted into the breached liquid injection part, a peristaltic pump is turned on, the peristaltic pump speed is adjusted, and the swelling liquid is uniformly infiltrated into the body through the shunt device 50, so that the purpose of synchronous swelling anesthesia of deep and shallow layers is achieved.
The liquid injection device for the liposuction swelling anesthesia can achieve the purpose of rapid deep and shallow layer simultaneous swelling, and meanwhile, the water flow of the device is not directly injected, but is used for reflecting pain and discomfort through more than 120 clinical cases in a flexible infiltration mode, so that even a patient can make a call, brush a comma, watch a movie, drink water and the like in the operation.
Referring to fig. 2-3, in one embodiment of the present invention, the liquid collection device 10 includes a liquid collection bottle 11, a bottle stopper 12, and a liquid suction tube, wherein a liquid collection cavity is located in the liquid collection bottle 11, and the bottle stopper 12 is mounted on a bottle mouth 111 of the liquid collection bottle 11 and seals the bottle mouth 111. The bottle stopper 12 includes a main stopper body 121, wherein the main stopper body 121 may be made of a material having a certain elasticity (e.g., silica gel), and the main stopper body 121 has a filling port for filling the swelling liquid into the liquid collecting bottle 11.
The first end of the pipette passes through the main plug body 121 and is inserted into the liquid collecting bottle 11, and the second end of the pipette is positioned outside the liquid collecting bottle 11 and is connected with an infusion pipeline (such as a silicone tube of a peristaltic pump). I.e. via an infusion line to the drive unit 30. Thus, the liquid swelling in the liquid collecting bottle 11 can be pumped out by the liquid suction pipe under the action of the driving device 30. The liquid injection port is used for injecting the swelling liquid into the liquid collection bottle 11, and the liquid injection port also has a pressure release function, so that the phenomenon that the swelling liquid cannot be extracted due to too small pressure in the liquid collection bottle 11 after the swelling liquid flows out is avoided. Of course, a pressure release through hole independent of the liquid injection port may be provided on the main plug body 121 to release the pressure in the liquid collecting bottle, so as to ensure that the swelling liquid in the liquid collecting bottle 11 can be smoothly extracted.
In one embodiment of the present invention, the liquid suction tube may specifically include a connection tube portion 123 and a liquid guiding tube portion 124, wherein the connection tube portion 123 is made of a hard material and is fixed on the main plug body 121, a first end of the connection tube portion 123 is located inside the liquid collecting bottle 11, a second end of the connection tube portion 123 is located outside the liquid collecting bottle 11, and the infusion line is connected to the second end of the connection tube portion 123. The liquid guide tube 124 is located in the liquid collecting bottle 11, and a first end of the liquid guide tube 124 is connected with a first end of the connection tube 123, and a second end of the liquid guide tube 124 extends to the bottom of the liquid collecting bottle 11.
In particular, a bottom member 125 may be added to the second end of the liquid guiding tube 124, for example, the bottom member 125 may be formed by a metal disc (the periphery of the lower surface of the metal disc protrudes, and the middle of the lower surface of the metal disc is recessed upward), and has a through hole thereon, the second end of the liquid guiding tube 124 is inserted under the metal disc, and the liquid above the metal disc passes through the through hole on the metal disc to reach under the metal disc and enters under the liquid guiding tube 124. Because the bottom of the metal disc is attached to the bottom of the liquid collecting bottle 11, most of the swelling liquid in the liquid collecting bottle 11 can be output to the flow dividing device, and the swelling liquid in the liquid collecting bottle 11 is prevented from being remained.
In another embodiment of the present invention, the bottle stopper 12 further comprises a cover 122, the cover 122 is rotatably mounted on the main stopper 121 with respect to the main stopper 121, and the pipette passes through the cover 122. The main plug body 121 has a first liquid inlet 1211, and the cover plate 122 includes a second liquid inlet 1221, so that the first liquid inlet 1211 is exposed from the second liquid inlet 1221 and the cover plate 122 covers the first liquid inlet 1211 by rotating the cover plate 122 relative to the main plug body 121.
Thus, when it is desired to add tumescent fluid to the fluid collection bottle 11, the cover plate 122 can be rotated to align the second fluid injection port 1221 with the first fluid injection port 1211 and the prepared tumescent fluid can be poured into the fluid collection bottle through the second fluid injection port 1221 and the first fluid injection port 1211. After the swelling liquid is poured, the cover plate 122 is rotated to stagger the second liquid injection port 1221 and the first liquid injection port 1211, and other parts on the cover plate 122 cover the first liquid injection port 1211 to prevent sundries from falling into the liquid collection bottle 11.
Further, a third filling port 1212 may be provided in the main plug body 121, and by rotating the cover plate 122 with respect to the main plug body 121, the third filling port 1212 may be exposed from the second filling port 1212, and the cover plate 122 may cover the third filling port 1212. The swelling fluid in the swelling fluid bag may be injected into the fluid collection bottle 11 by inserting a catheter connected to the swelling fluid bag into the third fluid injection port 1212.
Specifically, the cross sections of the first liquid injection port 1211 and the second liquid injection port 1212 on the main plug body 121 are respectively in the shape of sectors of the same size (the area of the cross section of the first liquid injection port 1211 is smaller than half of the area of the cross section of the main plug body 121); the cross section of the third injection port 1212 is circular, and the area of the cross section of the third injection port 1212 is smaller than the area of the cross section of the second injection port 1221.
In order to smoothly rotate the cover plate 122, a metal plate 126 is fixed to the surface of the main plug body 121 facing the cover plate 122, and through holes 1261 and 1262 corresponding to the first injection port 1211 and the third injection port 1212 are formed in the metal plate 126. Because the friction coefficient of the metal sheet 126 is smaller, the metal sheet is matched with the main plug body 121, so that the smooth rotation of the cover plate 122 can be ensured while the bottle mouth of the liquid collecting bottle 11 is blocked.
In one embodiment of the present invention, to improve the comfort of the operator, the liquid collection bottle 11 includes a metal shell, and accordingly, the liquid collection device 10 includes an electromagnetic heater 13, and the top of the electromagnetic heater 13 has a heating surface adapted to the bottom of the metal shell. Like this, the accessible electromagnetic heater 13 carries out the heating treatment to the swelling liquid in the liquid collecting bottle 11 for the temperature of the swelling liquid that pours into the art person subcutaneous into and human temperature looks adaptation, improves art person's comfort level.
Referring to fig. 4, in an embodiment of the present invention, the flow dividing device 50 may be made of a metal material or a polymer material (for example, PC, PVC, PMMA, PET, etc., without limitation herein), and includes a main body 51, a plurality of liquid outlet members 52, and a plurality of switch valves 53 (for example, three-way valves), wherein the liquid outlet is located on the liquid outlet members 52, and the switch valves 53 are respectively mounted on the main body 51. The main body 51 is tubular, and the liquid outlet members 52 are connected to the main body 51, respectively, and are arranged in one or more rows along the length direction of the main body 51. In practical applications, the number of the liquid outlet members 52 and the switching valves 53 may be specifically determined according to practical situations.
Specifically, the infusion chamber 511 is formed in the main body 51, and each liquid outlet member 52 is formed with a liquid outlet channel 521, and each liquid outlet channel 521 is connected to the infusion chamber 511 through a switch valve 53, and the switch valve 53 controls the connection and disconnection between the corresponding liquid outlet channel 521 and the infusion chamber 511, that is, each liquid outlet channel 521 is respectively connected to the infusion chamber 511 (the liquid inlet is located at the free end of the infusion chamber 511, and the liquid outlet is located at the free end of the liquid outlet channel 521), and a switch valve 53 is installed at the connection position between each liquid outlet channel 521 and the infusion chamber 511, so that the connection and disconnection control of the liquid outlet channel 521 can be achieved by driving the switch valve 53. In addition, since each of the liquid outlet passages 521 is communicated with the liquid transferring chamber 511, the plurality of liquid outlet members 52 are preferably integrally formed with the main body 51 (for example, integrally formed by a casting process), so that the plurality of liquid outlet members 52 and the main body 51 can be seamlessly connected, and leakage caused by an assembly gap between the liquid outlet members 52 and the main body 51 is avoided.
Because the main body 51 is tubular, injecting the external liquid from one end of the infusion chamber 511 can improve the smoothness of the liquid entering the infusion chamber 511, avoid the effect of the swelling liquid impacting the inner wall of the infusion chamber 511 to flow into the liquid outlet channel 521, and ensure the liquid to be output efficiently through the liquid outlet channel 521.
In particular, the main body 51 is provided with at least one port for injecting an external liquid (e.g., anesthetic) from one end of the infusion chamber 511 into the infusion chamber 511, and the port is preferably oriented along the length of the infusion chamber 511. In addition, at least a part of each on-off valve 53 is located in the infusion cavity 511 and controls the on-off of the infusion cavity 511, i.e. the on-off valve 53 for on-off of each liquid outlet channel 521 can also control the on-off of the infusion cavity 511. In practical applications, each on-off valve 53 may only control the on-off of one liquid outlet channel 521.
Since each of the liquid outlet channels 521 is controlled to be on-off by one of the switch valves 53, and the switch valves 53 also control the on-off of the infusion chamber 511 at the same time, the on-off of each of the liquid outlet channels 21 is made independent and controllable, so that the number (e.g., two, three, etc.) of the liquid outlet channels 521 for outputting liquid can be adjusted according to actual needs, and the practicality and controllability of use are improved.
In one embodiment of the present invention, a plurality of valve mounting locations 512 adapted to the on-off valve 53 are disposed in the infusion chamber 511, and the plurality of valve mounting locations 512 are arranged along the length direction of the infusion chamber 511. Specifically, each liquid outlet channel 521 is respectively communicated with the infusion cavity 511 through a valve mounting position 512, and each valve mounting position 512 is respectively provided with a switch valve 53, so as to ensure that the switch valve 53 can reliably perform the on-off function on the liquid outlet channel 521, and simultaneously ensure the stability of the switch valve 53 mounted on the main body 1.
Because the switch valve 53 on the valve mounting position 512 needs to simultaneously switch on and off the infusion cavity 511 and the liquid outlet channel 521, the switch valve 53 is preferably a three-way valve, so that each three-way valve can control the switch on and off between one liquid outlet channel 521 and the infusion cavity 511 and the switch on and off at the corresponding position of the infusion cavity 511, that is, the switch on and off function of the infusion cavity 511 and the liquid outlet channel 521 can be simultaneously achieved by one three-way valve, thereby effectively simplifying the structural design, reducing the weight and the volume of the water injection auxiliary device, and further preventing the structural complexity caused by the need of arranging more switch valves to realize control.
In one embodiment of the present invention, the main body 51 includes two external interfaces, the two external interfaces are a first external interface 513 and a second external interface 514 respectively located at two ends of the main body 51, the liquid inlet is located on the first external interface 513, wherein the first external interface 513 is directly communicated with the infusion cavity 511, the second external interface 514 is communicated with the infusion cavity 511 through the switch valve 3, and the plurality of liquid outlet members 52 are respectively located between the first external interface 513 and the second external interface 514. The on-off valve 53 between the second external interface 514 and the infusion chamber 511 may be a two-way valve, which may be a three-way valve or a two-way valve to improve uniformity of structural design.
Since the second external connection port 514 is communicated with the infusion chamber 511 through the on-off valve 53, the on-off valve 53 can be closed when external liquid is only required to be injected into the infusion chamber 511 from the single port of the first external connection port 513, so that the liquid in the infusion chamber 51 cannot flow out through the second external connection port 514. When external liquid needs to be injected into the infusion chamber 511 through the two ports, the switch valve 53 is opened, and external liquid is simultaneously input into the infusion chamber 511 through the first external connection port 513 and the second external connection port 514. Of course, in practical application, the switch valve 53 may be disposed between the first external connection port 513 and the infusion chamber 511, which may be specifically determined according to practical situations.
The shapes of the first external connection interface 513 and the second external connection interface 514 are adapted, so that the shunt device 50 can be connected with the first external connection interface of another shunt device through the second external connection interface 514, and expansion of the liquid storage port is achieved. Specifically, the first external connection interface 513 and the second external connection interface 514 of the present embodiment are circular in shape, so as to match the tubular main body 1, and facilitate processing. Of course, the shapes of the first external connection interface 513 and the second external connection interface 514 can be specifically adjusted according to practical situations, for example, square. Preferably, the first external interface 513 and the second external interface 514 are of equal shape and size, which facilitates compatible use, avoids the need for more-sized external syringes (e.g., syringes), and increases ease of operation to reduce the types of tools used for tumescent anesthesia procedures.
To ensure that the liquid in the infusion chamber 511 can relatively uniformly enter each of the liquid outlet channels 521 and that the liquid entering each of the liquid outlet channels 521 can be output under a relatively large pressure, the pipe diameter of the liquid outlet channel 521 should be smaller than the pipe diameter of the infusion chamber 511. Also, a plurality of water blocking members for adjusting the pressure of the liquid entering the plurality of liquid outlet passages 521 may be provided in the main body portion 51, and the liquid outlet pressures at the plurality of liquid outlets may be made the same by the water blocking members.
In particular, each switching valve 53 includes a driving handle 531 for controlling on-off of the infusion cavity 511 and the liquid outlet channel 521, and the distance between two adjacent valve mounting positions 512 is greater than the distance between the driving handle 531 protruding vertically along the direction perpendicular to the valve mounting positions 512, so that interference of the switching valves 53 mounted on the two adjacent valve mounting positions 512 is avoided, and reliable driving of the driving handle 531 in place is ensured. To prevent misoperation, each switch valve 53 is provided with a mark for guiding the driving handle 31 to rotate so as to realize on-off of the infusion cavity 511 and/or the liquid outlet channel 521.
In another embodiment of the present invention, as shown in fig. 6 and 7, to increase the number of liquid outlets of the flow dividing device 50, the size of the cross section of the main body 551 of the flow dividing device 50 may be appropriately increased. Specifically, in the present embodiment, the cross section of the main body 551 is a rounded rectangle (or rounded square), and liquid outlets 552 are respectively provided on three sides of the main body 551. The liquid inlet 553 is disposed at one end of the main body 551, and the other end of the main body 551 is also provided with a liquid outlet 552. The main body 551 has an infusion chamber for communicating the liquid inlet 553 with each of the liquid outlets 552.
To facilitate cleaning of the main body 551 and also to facilitate production and processing of the main body 551, the liquid outlet 552 at the end of the main body 551 is detachably fitted to the fitting opening 555 at the end of the main body 551. Specifically, the liquid outlet 552 may be located on a plug 554, where the shape and size of the plug 554 are matched with those of the fitting opening 555 on the main body 551, and the plug 554 has a through hole matched with the liquid outlet 552, and the through hole is used to communicate the infusion cavity in the main body 551 with the liquid outlet 552 on the plug 554. To avoid leakage, gaskets may be added to the end face of the plug 554 that plugs into the body 551.
