Description

"HUMANOID HEMODIALYSIS SIMULATOR"

[0001] This patent relates to the technical field of simulators for medical and hospital use in general, more specifically to a humanoid hemodialysis simulator which, according to its general characteristics, has as its basic principle to provide for the formation of a hemodialysis simulator in its own specific humanoid structure of the electromechanical type based on the introduction of a suction pump with an activation circuit, a central reservoir with supports and connections, a rear protection door, a rear supply opening and a flow control drive circuit, with a view to enabling, in an extremely practical, safe and economical manner, complete optimization of the procedures for structuring and applying blood pumping between the standard hemodialysis machine and the hemodialysis simulator, specifically the "Simulator for Hemodialysis Process", the subject of patent application BR 10 2020003433 2.deposited on 02 / 19 / 2020 and published on 08 / 31 / 2021, having the same owner and inventor Renata Aparecida Cândido da Silva and, based on a hemodialysis simulator with great resistance, safety and versatility.,

[0002] With a specific design and format and easy access for better adaptation and user safety, practical handling and functionality, affordable costs and, due to its general characteristics and dimensions, easily adaptable to a wide range of humanoids, hemodialysis machines, locations, patients and nursing technicians in general, regardless of the characteristics they may present.

[0003] It's worth noting that hemodialysis is the procedure through which a specific machine filters and cleans all of a kidney patient's blood, performing some of the work that the diseased kidney cannot perform with the desired and necessary quality. The process involves removing harmful waste products from the kidney patient's body, such as excess salt and fluids, as well as controlling blood pressure and helping the body maintain a balance of substances such as sodium, potassium, urea, and creatinine.

[0004] Hemodialysis is indicated for patients with kidney failure of the severe acute or chronic type, so the indication to start this treatment is made exclusively by a doctor specializing in kidney diseases, that is, a nephrologist. It is important to note that dialysis is not intended to treat kidney disease, but rather to replace the function of impaired kidneys.

[0005] Treatment for kidney failure may begin with specific medications that aim to control symptoms and stabilize the disease. In cases where medications are insufficient and the disease progresses, hemodialysis may be necessary. This decision is made jointly with the patient and their nephrologist. Hemodialysis sessions are usually performed in specialized clinics or hospitals by nurses, specialized nursing technicians, and other healthcare professionals.

[0006] In general, dialysis involves filtering blood that is gradually withdrawn from the body through a special needle to puncture an arteriovenous fistula (AVF). This is a connection between a small artery and a small vein, making the vein thicker and more resistant so that punctures can be performed without complications. The fistula can be created using the individual's own veins or synthetic materials, and is prepared with minor surgery on the arm or leg, performed by a vascular surgeon under local anesthesia.

[0007] Similarly, dialysis can also be performed using a catheter inserted under local anesthesia directly into a vein in the kidney patient's neck (subclavian or right or left jugular), chest, or groin. The catheter is generally a temporary option for kidney patients who require dialysis but do not yet have a fistula. The main problems associated with catheter use are obstruction and improper handling that can lead to infection, which often requires removal and the implantation of a new catheter for continued sessions.

[0008] It should be noted that the hemodialysis method is a therapeutic modality intended for the treatment of critical and / or severe patients, so it is the responsibility of Nephrology nursing teams perform technical procedures related to the direct and ongoing care of kidney patients undergoing hemodialysis at each stage. This care includes preparation, fistula puncture or catheter management in kidney patients, monitoring, programming the hemodialysis machine and assembling the circuit, changing solutions, and providing physical and emotional care to kidney patients, among other tasks.

[0009] However, the high complexity and, consequently, the great difficulties in training nephrology nursing teams with excellence, primarily nephrology nursing teams in hemodialysis procedures, which are all based on traditional “machine-side” training, which is carried out during the patient's hemodialysis session itself, using the treatment time, reducing the opportunity for better removal of waste from the patient's body.

[0010] Specifically, chronic kidney patients, having lost their kidney function, depend exclusively on the hemodialysis machine to remove toxins from their body. Every time a professional interrupts the hemodialysis machine to train another professional, they are directly violating the patient's right to receive their treatment within the prescribed time and within the established protocols. In other words, it would be as if the professional were taking the patient's medicine.

[0011] In this way, all questions regarding the technical procedures that must be performed are made directly in front of the patients who are undergoing hemodialysis, that is, they naturally find themselves in a delicate situation and end up being totally insecure with those joint application and learning procedures, so that it becomes difficult for the nephrology nursing teams, as well as for generating a lot of exposure for both parties.

[0012] In a broad analysis of the literature with the aim of establishing the current state of the art regarding hemodialysis simulators, primarily simulators in humanoid configuration, the object of this patent, only the invention patent application BR 10 2020 003433 2 - "Simulator for Process of Hemodialysis", as relevant to the state of the art that relates to the specific object claimed.

[0013] However, although this first patent application presents excellent results in terms of learning for nephrology nursing teams, having become a disruptive technology or even a disruptive innovation, which caused a complete break with medical standards, models or technologies already established in hemodialysis procedures, the simulator required therein still presents some drawbacks that need to be largely overcome through improvements and optimizations in its basic structure, such as, for example, the procedure for pumping the blood flow inside it as recirculation and the procedures for supplying, supporting and accessing / securing the blood reservoir.

[0014] In this line of action, it has become increasingly essential for nephrology nursing teams that are in the midst of training processes to develop a new, versatile, safe and practical hemodialysis simulation structure that is based on a set of improvements and optimizations on the existing structure in the previous patent application "Simulator for Hemodialysis Process" that is capable of fully overcoming these important existing drawbacks, reducing the cost and training time, as well as the possible suffering of kidney patients undergoing hemodialysis procedures.

[0015] Thus, the patent in question is characterized by combining components and processes in a unique design that will meet the diverse requirements of its intended use, namely, the simulation of hemodialysis procedures in patients with severe acute or chronic renal failure. This design guarantees a hemodialysis simulator with great efficiency, functionality, strength, durability, safety, versatility, practicality, precision, and cost-effectiveness due to its excellent combined technical qualities. This provides advantages and improvements in the training procedures for nephrology nursing teams through a humanoid simulator, and whose general characteristics, differ from other shapes and models known in the current state of the art.

[0016] This patent consists of the use of a modern, efficient, safe and functional humanoid hemodialysis simulator formed by a set of correctly incorporated electromechanical and medical solutions, composing a complete and differentiated hemodialysis simulator with an exclusive design, beautiful aesthetic appearance and unique characteristics, which incorporates its own specific humanoid structure of the electromechanical type, of high durability and resistance, and containing perfectly introduced, integrated and symmetrically arranged a suction pump with an activation circuit as an element for distributing the blood flow inside the hemodialysis simulator from the central reservoir; a central reservoir with supports and connections as an element for storing the blood inside the hemodialysis simulator for subsequent distribution;a rear protective door as a protective element for the internal compartment of the hemodialysis simulator and controlling access to the central reservoir; a rear supply opening as an element for externally supplying blood to the central reservoir through the upper pipe; and a flow control drive circuit as an element for controlling blood flow within the hemodialysis system, in order to enable the formation of a single, complete and safe set, whose shapes and internal and external arrangements allow perfect adaptation to a wide range of humanoids and hemodialysis processes in general, being specially designed for these purposes.;

[0017] Thus, the general design of the present humanoid hemodialysis simulator, which is the subject of this patent, is entirely based on its simple and robust structure with a minimum of components and extremely simplified, safe and optimized operation, combined with very practical manufacturing and maintenance procedures, in order to generate a practical and efficient hemodialysis simulator based on improvements and optimizations introduced in a humanoid simulator, aiming to humanize and simplify the training of nephrology nursing teams that perform the procedures. hemodialysis procedures, that is, a humanoid in the form of a doll or any other format with an improved and optimized set of components that allow to fully simulate the blood current / flow in a similar way to the hemodialysis procedure in patients with kidney diseases, since kidney patients are replaced in all stages of the hemodialysis procedure, from preparation to exit.

[0018] Specifically, inside the hemodialysis simulator that is connected to a hemodialysis machine, replacing the patient with the humanoid, the entire circulatory system of a hemodialysis process is simulated, giving perfect reality to hemodialysis sessions, where the blood reservoir, the reservoir suction pump and the arterial and venous lines that come out of the upper limbs, subclavian, right or left jugular, as well as the abdomen are connected.

[0019] These new components introduced directly into the simulator for hemodialysis processes allow for a much better, through their complete optimization, entire process of learning, training and practice of hemodialysis by nephrology nursing teams, from the handling of the hemodialysis machine to the preparation and removal of the renal patient undergoing treatment, completely replacing this renal patient with the simulator and hemodialysis for the training of new nursing teams or any healthcare professional.

[0020] This hemodialysis simulator is based on the application of components and processes in a differentiated design, without, however, reaching a high degree of sophistication and complexity, making it possible to solve some of the main drawbacks of other forms and models known by the current state of the art and used in hemodialysis simulation procedures in renal patients, aiming at the learning of nursing teams, which are in a work range in which the forms and / or models present difficulties of use and application, low efficiency and performance, frequent accidents, risk of iatrogenesis, great deterioration and fragility, low versatility, low precision, high insecurity, low performance, high losses, high cost, complex handling, high maintenance, huge waste of time and complex manufacturing.

and an activation circuit with a microcontroller arranged inside the protective cover and interconnected to the water vacuum pump (2B); - a central reservoir (3) arranged vertically and symmetrically centered in the internal part of the internal compartment (A) and on the pump and suction (2), internal part of the chest of the hemodialysis system (1), and comprising two posterior supports / clamps (3A) curved and arranged horizontally, parallel and symmetrically spaced in the posterior part of the internal compartment (A); two anterior locks (3B) rectilinear and arranged horizontally, parallel and symmetrically spaced in the front of the internal compartment (A); a cylindrical reservoir (3C) arranged vertically and symmetrically supported on the vacuum pump (2), fitted / fixed by its rear faces around the front faces of the two rear supports (3A), and locked by its front faces on the rear faces of the two front locks (3B), storing all the blood necessary for the blood flow of the hemodialysis simulator (1); a cylindrical lower cover (3D) arranged horizontally, parallel and symmetrically under and around the entire length of the lower face of the reservoir (3C); a cylindrical upper cover (3E) arranged horizontally, parallel and symmetrically under and around the entire length of the lower face of the reservoir (3C) and having two circular upper threaded openings (3F) and arranged symmetrically spaced on the upper cover (3E);a cylindrical screw cap (3G), arranged symmetrically around one of the upper holes (3F) and having a sealing ring arranged around the entire upper extension of the internal part of the screw cap (3G) and three circular upper openings (3H) arranged symmetrically spaced in the screw cap (3G) and interconnected by a hose / connection (31) originating from the insertion point of the subclavian catheter (C) in the neck, by a hose / connection (3J) originating from the arterial fistula point (D) as the outlet of the arterial line in the region of the wrist of the left arm and by a hose / connection (3K) originating from the venous return point (E) as the outlet of the venous line in the region of the wrist of the left arm, blood flow through the interior of the hemodialysis simulator (1); and a curved pipe (3L) arranged symmetrically connecting the other upper hole (3F) to the rear feed opening (4), inlet and outlet connection for the fluid that flows into the reservoir; - a circular rear feeding opening (4) arranged parallel and symmetrically centered on the postero-upper part of the chest of the hemodialysis system (1), aligned and spaced from the upper end of the rear protective door (5), interconnected to the internal part of the internal compartment (A) of the hemodialysis system (1) and to the reservoir (3C) by means of the pipe (3L), and comprising a screw cap (4A) arranged symmetrically around the entire external part of the rear feeding opening (4), for the inlet and outlet of all the blood fluid artificial that supplies the reservoir (3C) of the hemodialysis simulator (1); - a rear protective door (5) arranged vertically, parallel and symmetrically centered on the rear part of the chest of the hemodialysis system (1), completely aligning the opening of the internal compartment (A) of the hemodialysis simulator (1), comprising a plate (5A) arranged vertically, parallel and symmetrically along the entire length of the opening of the internal compartment (A); a set of fixed fasteners (5B) arranged symmetrically spaced around the entire length of the rear part of the chest of the hemodialysis simulator (1) adjacent to the rear protective door (5) and fixing the structure of the rear protective door (5); and a set of removable fasteners (5C) arranged symmetrically spaced around the entire length of the lateral ends of the rear protective door (5) and fixing / locking the rear protective door to the hemodialysis simulator (1); and - a flow command drive circuit (6) arranged symmetrically inside the skull region of the hemodialysis simulator (1) and interconnected to the activation circuit with the suction pump microcontroller (2), and comprising an integrated circuit with microcontrollers (6A) in which there is the Power (Jl), grounding (J2) and voltage input (J3); a DC power battery; and an internal pump (6B) interconnected to the integrated circuit with microcontrollers (6 A) and to the reservoir (3C), so that the water vacuum pump (2B) works simultaneously as reinforcement in pumping the fluid in the internal circuit of the humanoid simulator (1) and hemodialysis machine.

[0033] The humanoid hemodialysis simulator, according to the application needs, can be comprised of an electrocardiogram or electrocardiography simulator - ECG, placed inside the hemodialysis simulator and interconnected to the flow command drive circuit, allowing the simulation of the heartbeats of kidney patients, through the evaluation of the electrical activity of the heart through electrodes fixed to the skin, that is, also detecting the heart rhythm and the number of beats per minute.

[0034] The humanoid hemodialysis simulator, according to the application needs, can be comprised of a structure in the shape of any type of pets rather than humanoid format, since the procedures and equipment used for hemodialysis in pets, whatever they may be, are the same as those used in humans.

[0035] The humanoid hemodialysis simulator, according to the application needs, can be comprised of a structure in which the lower limbs are made of foam material, so that the legs are flexible / foldable for storage in case-type suitcases for safer and more practical transportation.

[0036] The introduction of the suction pump (2) into the hemodialysis simulator (1) allows for the ideal pressure of the suction pump (2) to pump the blood flow inside the hemodialysis simulator (1) through its activation by the activation circuit with microcontroller, and the microcontroller of the activation circuit emits a PM (pulse width modulation) signal, intended to control the pressure of the suction pump (2).

[0037] The structuring of a new central reservoir (3) placed inside the internal behavior (A) of the chest, as well as its new seals and connections, is highly necessary due to the logistics, transportation and packaging procedures of the hemodialysis system (1) for the application sites, as the old gallon weighed a lot and, mainly, the blood fluid contained inside it leaked a lot due to the fragility of the old seals and connections on the gallon lid, as well as for safety against unwanted access such as violations.

[0038] The introduction of a posterior feeding opening (4) located in the postero-superior part of the humanoid's trunk was necessary to allow a practical and safe manual procedure for filling and emptying the central reservoir (3) without any type of exposure of the internal part of the hemodialysis simulator (1). In the previous version of the hemodialysis simulator, it was necessary to open the old door completely to be able to perform the manual procedures for filling and emptying the old gallon.

[0039] The new structure of the rear protection door (5) introduced in the part The rear trunk of the hemodialysis simulator (1) no longer has the padlock or the pair of hinges from the previous version, which were replaced in this new version by a set of fixed (5B) and mobile (5C) fasteners arranged around the entire length of the plate (5 A) of the rear protective door (5). This change was necessary due to the fragility of the structure and opening of the door in the previous version, as the sides of this old model were vulnerable to opening, since the padlock was only on one side of the door, while the pair of hinges that could be easily removed were on the other side.

[0040] Thus, with this modification to the rear protective door (5) based on a set of fixed (5B) and mobile (5C) fasteners, the new rear protective door (5) has greater security, including allowing the new central reservoir (3) to be accommodated in a practical and safe manner in the internal compartment (A), whereas before the container was completely loose inside the previous version of the humanoid simulator.

[0041] The introduction of a flow control drive circuit (6) into the hemodialysis simulator (1) has the essential purpose of activating a pump to maintain blood flow within the hemodialysis simulator (1) during hemodialysis procedures. Thus, the introduction of the flow control drive circuit (6) and its components, such as the integrated circuit with microcontroller (6 A) and the internal pump (6B), which are extremely important for the perfect functioning of the hemodialysis simulator (1), is carried out in the upper part of the hemodialysis simulator (1), specifically in the cranial region, so that its inlet and outlet are directly connected to the suction pump (2), as this will allow the important and necessary blood flow recirculation process to occur.

[0042] It is also worth highlighting that the humanoid hemodialysis simulator, according to its new internal technological design, allows its application both in humans and in a wide range of animals without any significant changes in its structures and components, as well as in its application and operation method.

[0043] Because the humanoid hemodialysis simulator's components are fully integrated, nothing can come loose, and nothing can break or bend. This achieves high performance and efficiency, combined with high durability and absolute safety. Once fully integrated with each other, the simulation humanoid, and the hemodialysis machine, the components are cohesive, preventing them from coming loose during use. The system is fully available for hemodialysis simulation procedures in nephrology nursing team training. Thus, the hemodialysis simulator (1) can be used without any concerns, particularly regarding the durability and safety of its components, as well as the safety of nursing technicians and patients.

[0044] The humanoid hemodialysis simulator offers specific advantages: complete safety for kidney patients, as they no longer actively participate in the training of nursing teams or health professionals in general, being replaced by the hemodialysis simulator; high technical training for nephrology nursing teams, as they can practice without direct concern for kidney patients who are replaced by the hemodialysis simulator; low accident rates due to technical failures by medical teams, as they can practice with greater versatility, concentration, and frequency; and a high capacity to project the most diverse situations existing in hemodialysis processes into training.

[0045] From all that has been explained, this is a medical simulator that will be well received by nephrology nursing teams and patients with chronic kidney disease in general, as the humanoid hemodialysis simulator offers numerous advantages, such as: great safety, reliability, and agility in application; great performance and efficiency in its application due to its general design; high comfort, convenience, and safety for nursing teams; extremely high resistance and overall durability, combined with low or no wear and tear on the entire system; fully affordable costs, which allows for an excellent cost / benefit ratio; practical and safe use by a wide range of teams. nursing; very low and practical general maintenance; high sterilization capacity; perfect and direct adaptation to the most diverse types of hemodialysis machines; high operational precision; excellent versatility in regulating blood flows and rates; high ergonomic capacity; and the certainty of having a hemodialysis simulator (1) that fully complies with current legislation and standards and the basic conditions necessary for its application as a whole.

[0046] All these attributes allow the humanoid hemodialysis simulator to be classified as a fully versatile, efficient, practical and safe means for simulating hemodialysis processes in the most diverse patients with chronic kidney disease, aiming at the most diverse types of training for a wide range of nephrology nursing teams in the most diverse locations such as hospitals and clinics, regardless of the general characteristics they may present, being also very easy to apply and handle, combined with great performance and excellent general characteristics; however, it is not limited at any time to the representations described here, and should be understood in its broad scope of claims, that is, not being limited to the specific form revealed, and that other similar forms are understood as fully included within the claimed scope.
