[026] 03 control means (1.1) comprise an electronic board (1.1.1) provided with micro controllers, digital and analog signal input and output interfaces, power control and communication interfaces; a control interface (1.1.2) for the flow rate of the fluid to be obtained; and a display (1.1.8) for displaying configured cctnx operating parameters.

[02 7 s the electronic board (1.1.1) connects to the other components of the apparatus of the invention in order to manage the function of each component. In this way, the plate (1.1.1) manages and controls the temperature in the cooling (1,2) and heating (1.3) reservoirs; the control interface; manages the rotation and power of each of the hi.drèuiieas tombs (1.4); manages the temperature, volume and flow of the outlet liquid in the mixers (1.6) and (1.7) and the pressure of the liquid reaching the end of the outlet through the circuit (i) through arn manome pressure sensor t; r:> ca (1. B).

[028] The control interface (: 1.1.2) comprises a set of actuators with a dual-stage mechanical drive system. Triggering occurs by the pressure of the actuator, the elevation level of the creator, the direct pressure of one of the actuators, or the direct pressure of a set of actuators. In the preferred embodiment of the invention, the control interface (1.1.2) is a pedal and the actuators are: i.3. This embodiment of the invention has the advantage that it allows the control of the parameters of the temperature, flow, pressure and volume of the fluid without the use of the signs which can remain in control of the endoscope during the medical procedure.

[030] The display (1.1.3) indicates the value of the flow temperature, pressure, flow and volume parameters that have been entered via the control interface (1.1.2).

[031] The refrigerated reservoir (.1.2) stores fluids; It has the ability to cool and maintain them at low temperatures as pre-set by the user of the washer in endoscopic procedures of the invention. In the preferred embodiment of the invention, the fluid is a liquid, such as, for example, water.

The refitted reservoir (2A) comprises container (2.1), lid (2.2) which tightly seals the container, temperature sensor (2.10) and means for cooling and maintaining the fluid. under constant temperature.

[033] An embodiment of the present invention with respect to the refrigeration reservoir (1.2) cooling elements comprises the cylinder (2.3) which has a prior art refrigerant gas contained under pressure (FIGURE 2h). During cooling mode, the cooling gas is released via the vat: val (2.4) regulating valve, which has a sertctecanisotageable by the control plate (1.1.1), which acts directly on the locking device. of the valve. Thus, the continuous flow of flow occurs from the total condition and closed to the fully open condition. The gas released by the valve is conveyed to the reservoir by means of the pipe (2.5) giving access to the container <2.1} through the connector (2.6), which internally connects with the coil (2.7) making its entire path to the exhaust point. (2.8).

Connector 2.6 is configured as a flow restricted valve where gas is transferred to. a ca v, i d ad i η t e i: n a d a s e r p e η 1: 1 n a (2.7), hollow. I refer to the reduction of its pressure and, consequently, to its temperature, which is refractory.

[0.3.5] Serpentn.sa (2.7) is built inside ddsipader (2.9) and makes contact with all its auction houses. Gas> f1ui from the circulating flow controlled refrigerant is capable of cooling the dissipated coil assembly (2.7) ::: (2.9) so that, in contact with the fluid, it absorbs heat and thereby decreases heat. , the temperature. After pass: through all the content of serpeiocina. (2.7), the refrigerant gas '' is ejected into the external environment at the exhaust point (2.8). Na) 1 i. In this invention, the present invention (2.8) contains a device for reducing gas noise and protecting the coil by means of its particle input. which comprises a small foam tube contained in paragraph 11 (2.8).

[0 36] Cyclic flow org anation is performed by a 100: t roll closed compensation system. Going: You're gone. Finger flow is adjusted to keep the temperature within the value entered in the control means (1.1). The temperature sensor ¢ 2.10) obtains the fluid temperature and communicates with the electronics board (1.1.1) assisting in the final temperature setting.

[.0 3-7] the refrigerated container (Figure 2) further comprises the heat absorbers (= heat (2.11), which are preferably Peltier tablets. The heat absorbers (2.11) have the hot face coupled to the external heatsinks ( 2.12) and the cold face coupled to the inner sink (2.9) by means of the bases (2.13) which serve for coupling and thermal conduction.Optionally, the external heatsinks (2.12) have exhaust hoods to increase the heat flow during cooling. During the liquid cooling process, the control system may connect heat absorbers (2.11) so as to keep the system within the eont curve. When the final temperature is reached, the system enters the temperature maintenance mode by means of the heat absorbers (2.11), in which mode the tablets may operate in a relay, linearly controlled? u theme i co compensating or alternating on and off states by known techniques such as pulse width modulation (PvCM). Through these processes, the final temperature was within a minimum range of the set temperature. An additional embodiment of the present invention with respect to the cooling means of the refrigerated reservoir (2) comprises a small size refrigeration system in which the fluid is generated; gets stuck in a circuit (FIGURE 2B).

It basically sets up a thermal machine that operates in the cooling cycles.

[03 9 j In Figure 2B it is shown how the alternative cooling cycle works. The refrigerant is introduced at high pressure into the serpentine inlet connector (2.22) and is discharged into a low pressure environment in a manner analogous to the foregoing. Refrigerant fluid is conducted through the coil outlet conductor (2.19) due to the low pressure generated by the compressor inlet (2.20). After passing through the compressor (2.20), the refrigerant is again under high pressure and, as a result of the slight (high, in terajitui) effect when passing through the disinfector (2.21), the excessive temperature of the refrigerant is reduced due to the device's ability to dissipate heat to the environment, thus completing the idle.

[040} The refrigerated reservoir (Figure 2} further comprises a fluid cycler comprising a set of propellers (2.14) fixed to a transfer shaft (2.3.5) which is coupled to a motor (2.16). It is located above the cap of the river. Loirí Puraçu performs a creeping movement within the fluid, which forces all the liquid to make it: contact with the heat-absorbing lines (2.11), thus assisting in the process. de ces fi: iamenizo e na-nutiiía ia tazj u, t 1 fluid.

[04: 1] The refrigerated reservoir (2) is connected to the pump mechanism (1.4.3) through hoses connected to the outlet (2.17). The breather (2.18) acts as a breather for regulating the internal pressure of the reservoir.

The heating reservoir (3) comprises the reservoir (3.1) and the hermetic lid (3.2). This reservoir further comprises the electrical resistor (3.3) inserted below the heatsink (3.4) and the propeller (3.5), through which circulates an electric current 1 π l so that the dissipated power occurs in the form of heat, a phenomenon known for effect. 11 oJ or 1 e.

The motor (3.10) drives the shaft (3.11) which is coupled to the propeller (3.54), causing the fluid to flow through the heatsink of the heatsink (3.4) provided quick and homogeneous fluid heating.

The user can previously configure the washer drilling parameters in endoscopic procedures via the control interface (1.1.2), ie the user can configure the flow, pressure, temperature, time and volume of the device. When the flow is set up, the physical control system manages the dope 1 after 1 tronic (1.1.1), activates each of the pumps (1.4) to operate in continuous rotation. proportional to the set flow and temperature, hydraulic (4.2) and (4.11). and of the fluid type thus as a function of the physical conditions of the pump (1.4), the closed loop ftuidic control system, implemented by the control board (1). 1.1) and the volumetric sensors (4.2) and (4.11), ci isporuuhi I za the power required for. ensure constancy; i flow.

[0 5 7] The installation temperature control curves establish the drive power parameters of each hydraulic pump by considering the dynamic temperature variation of the hydraulic pipes at the time of insertion, estimated by the sensors ( 1.6.3) and (1.7.3) installed on the mixers.

[059] The Lume flight can be configured in two ways as a safety imitator of the transferred fluid volume, or reconciled with the operating time.

Thus, when the preset time is reached, the pump mechanisms will automatically shut down even if the control interface (1.1.2) is held down.

[061] The pump (1.4.3) connected to the air filter (1.5) is intended to install gaseous fluid air to the hydraulic system in order to mix liquid gas at the outlet line (1.9). ). Gaseous fluid can be intermittently instilled in order to insert independent columns of air into the pipelines, thus generating instantaneous Loop at the flow lines observable at the moment of escape of the air column from the distal end, which impacts the attack pressure of the liquid on the secretion to be removed, thus promoting improved cleaning efficiency. The air filter 1.5 serves to remove impurities from the air that is injected into the washer in endoscopic procedures of the invention.

[062] Mixers {1.6} and (1.7) have the shape of a "Y" and each. It has two inputs and one output. Each inlet has a tinting valve capable of preventing fluid return. The mixer (1.6) controls the mixture between the refrigerant released by the refrigerant (1.2) with fluid; heating released by the heated reservoir (1.3) thereby more efficiently regulating the final temperature of the circulating fluid.

[065] Another advantage is its ability to automatically adapt to endoscopes with different constructive characteristics of the instrumentation channel. It is considered that, given the described control model, executed by a closed loop circuit which constantly evaluates the flow sensor (1.2) and (4.11) and pressure sensor signals (1.8) and compensates for the error by power regulation. Since the motor drive (4.1), with limits set by the Ranonietic pressure sensor (1.8), the method is capable of operating in endoscopes with different diameters and lengths of liquid channels, so that variations in flow and flow rate. Pressure generated between the equipments are evaluated and compensated by the electronic board's coatroLe system (1.1.1).
