The inventor of the application finds that the simulation lung simulator in the prior art is difficult to completely reconstruct the real human organ structure and also difficult to truly simulate the contraction and expansion of the lung when the human body breathes, and a training student cannot really feel the interference of breathing movement on examination and operation, so that the training effect is influenced.
Implementation mode one
In view of the above, referring to fig. 1 and fig. 2, a first embodiment of the present application provides an organ simulation apparatus, including: the container 1 and the simulated organ 2, the simulated organ 2 is arranged in the container 1, and an accommodating space 16 is arranged between the simulated organ 2 and the shell of the container 1. The organ simulation apparatus further comprises a pump assembly connected to the container 1 for adjusting the medium pressure in the accommodation space 16, and the simulated organ 2 expands or contracts in response to the change of the medium pressure.
The simulation organ 2 of the present embodiment can be applied to simulation training, so that the simulation organ can be used for simulating other parts such as heart, kidney, etc. besides lung, and the specific choice of the simulation organ does not limit the present embodiment.
Taking the simulated lung as an example, the simulated organ 2 may be a specimen prepared by antiseptic treatment of the lung of an animal or human body. Compared with the simulated lung in the prior art, the simulated lung adopts the lung specimen of an animal or human body as the simulated lung, so that the lung structure of the human body can be relatively completely and truly reproduced, a student is helped to be familiar with the lung structure, the effectiveness of simulation training is improved, and a real reference is provided for the student to accurately find the bronchus or simulate a focus.
More preferably, the simulated organ 2 of the present embodiment is a processed pig lung, which has a similar structure to a human lung, can well simulate a lung environment, and is low in cost and easy to obtain.
Referring to fig. 1, the container 1 may include a removable cover 12, wherein the cover 12 is sealingly connected to the container 1 by a gasket. The side wall of the container 1 may be further provided with a connection port 11, and an opening of the simulated organ 2 (for example, a trachea of a pig lung) is communicated with the outside through the connection port 11, wherein the connection port 11 may be fixedly connected with the container 1 through a movable joint. The opening of the simulated organ 2 and the connecting port 11 can be connected in a bundling way, the bronchoscope can extend into the simulated organ 2 through the connecting port 11, and a student can search the trachea or confirm a simulated focus point with the help of image vision assistance.
The pump assembly can adjust the medium pressure in the accommodating space 16, and the simulation organ 2 expands or contracts along with the change of the medium pressure, so that the contraction and expansion of the lung during human breathing can be simulated really. Compared with the prior art, the organ simulation device can improve the simulation degree of bronchoscope training, enables a student to practically feel interference caused by respiratory motion to bronchoscope use, is further familiar with the influence of respiratory motion when the bronchoscope is used, can accurately find the positions of bronchial branches and focuses, and improves the training effect.
The medium input into the accommodating space 16 may be a gas, such as air, nitrogen, carbon dioxide, etc.; or a liquid such as purified water, physiological saline, etc. Different environments can be simulated by adopting different media, and the adopted inert media can also provide protection for the simulated organ 2 and prolong the service life of the simulated organ.
In this embodiment, referring to fig. 2, the pump assembly may further include: a reversible bidirectional pump 31 and a connection pipe 32, one side of the reversible bidirectional pump 31 is connected with the connection pipe 32, and the other side is connected to the external medium accommodating space 4; the two ends of the connecting pipe 32 are connected with the reversible bidirectional pump 31 and the container 1 respectively. The connecting line 32 can be fixedly connected to the opening 15 in the housing of the container 1 by means of a bulkhead fitting.
Wherein, when the medium is air, the medium accommodating space 4 may be only a general external space. When the medium is another medium, the medium accommodating space 4 may be a container for accommodating the medium.
The reversible bidirectional pump 31 is connected with the container 1 through the connecting pipeline 32, and can quickly adjust the medium pressure in the accommodating space 16, so that the simulated organ 2 expands or contracts along with the change of the medium pressure. In the present embodiment, the reversible bidirectional pump 31 and the connection port 11 are used in combination, whereby the change of the simulated organ 2 during the respiration of the living body can be simulated more reliably. Specifically, the method comprises the following steps:
when the reversible bidirectional pump 31 pumps the medium from the container 1 to the medium accommodating space 4 outside, the medium in the accommodating space 16 becomes thin, and the pressure in the medium accommodating space 4 is lower than the outside pressure. At this time, the pressure difference between the inside and the outside of the container 1 causes the external medium to enter the simulated organ 2 through the connecting port 11 on the side wall of the container 1 and the opening of the simulated organ 2 to maintain the pressure balance of the whole container 1, thereby expanding the simulated organ 2.
On the contrary, when the reversible bidirectional pump 31 replenishes the medium into the container 1 from the outside, the density of the medium in the accommodating space 16 increases, and the pressure is higher than the outside air pressure. At this time, the pressure difference between the inside and the outside of the container 1 will extrude the simulated organ 2, so that the medium in the simulated organ 2 is discharged to the outside through the connecting port 11 on the side wall of the container 1 and the opening of the simulated organ 2 to maintain the pressure balance of the whole container 1, and further the simulated organ 2 is contracted.
The intermittent expansion/contraction of the simulated organ 2 can be realized by repeating the steps, so that the breathing movement can be truly restored, and the effectiveness of simulation training is improved.
It should be noted that the pump flow direction of the reversible bidirectional pump 31 can be switched manually in a manual manner according to the timing. The reversible bidirectional pump 31 can also be connected to the control device so that the steering can be switched automatically by means of the control logic provided by the control device. The time of the switching operation can be triggered by timing or calculating the fluid flow rate in the pipeline. The reversible bidirectional pump 31 is automatically controlled, manual intervention is not required in the process of switching the pump flow direction, and the convenience of operation can be improved.
Second embodiment
A second embodiment of the present application also provides an organ simulation apparatus. The organ simulation apparatus of the second embodiment is different from the organ simulation apparatus of the first embodiment; the main difference is that in a first embodiment of the present application, the pump assembly comprises a reversible bidirectional pump 31, whereas in a second embodiment of the present application, as shown with reference to fig. 3, the pump assembly may comprise: a first one-way pump 33 and a connecting pipe 32.
Wherein, there may be a plurality of connecting pipes 32, for example, the connecting pipes 32 may be respectively communicated with the first one-way pump 33, the container 1 and the external medium accommodating space 4; here, the pump flow direction of the first one-way pump 33 is a direction outward from inside the container 1, thereby forming negative pressure inside the container 1. At the same time, although not shown in fig. 3, the pump assembly may also comprise an electrically controlled valve 34, which electrically controlled valve 34 is arranged at a location of the connecting line 32 that communicates with the external medium receiving space 4.
Alternatively, referring to fig. 4, the connecting pipe 32 may be only one and have three branches, and the three branches are respectively communicated with the first one-way pump 33, the container 1 and the external medium accommodating space 4; here, the pump flow direction of the first one-way pump 33 is a direction outward from inside the container 1, thereby forming negative pressure inside the container 1. In this case, the electrically controlled valve 34 can be arranged on a branch of the connecting line 32 which communicates with the external medium receiving space 4.
As shown in fig. 1, the side wall or the bottom of the housing of the container 1 may be provided with a closable venting opening 13. The first one-way pump 33 and the ventilation port 13 may be connected to the external medium accommodating space 4, respectively, or may be connected to the external medium accommodating space 4 in a unified manner as shown in fig. 3.
In the present embodiment, the first unidirectional pump 33, the ventilation port 13, and the connection port 11 are used in combination, so that the change of the simulated organ 2 during the respiration of the living body can be simulated more reliably. Specifically, the method comprises the following steps:
the venting opening 13 is closed and the first unidirectional pump 33 is opened, the pump flow direction being the direction from the inside of the container 1 to the outside, which corresponds to the first unidirectional pump 33 drawing the medium from the container 1 to the outside, and a negative pressure can be formed in the container 1. At this time, the pressure difference between the inside and the outside of the container 1 causes the external medium to enter the simulated organ 2 through the connecting port 11 on the side wall of the container 1 and the opening of the simulated organ 2 to maintain the pressure balance of the whole container 1, thereby expanding the simulated organ 2.
Conversely, the first one-way pump 33 is switched off, wherein the first one-way pump 33 no longer draws off the medium from the container 1 to the outside. The venting port 13 is opened and the external medium enters the container 1 at a certain rate to maintain the pressure balance of the whole container 1, so that the pressure difference between the inside and the outside of the container 1 is reduced. The medium in the container 1 overflows at a certain rate through the air passage and the connection port 11.
The intermittent expansion/contraction of the simulated organ 2 can be realized by repeating the steps, so that the breathing movement can be truly restored, and the effectiveness of simulation training is improved. It should be noted that the ventilation port 13 may be provided independently of the connection port 11, or may be provided by combining three-way valves and the like.
Although the first one-way pump 33 can be manually operated according to the timing, the manual control method is obviously neither accurate enough nor physically consuming, and the accurate control and the improvement of the working efficiency can be realized by electrically controlling the valve 34.
Of course, the first unidirectional pump 33 and the electrically controlled valve 34 may be connected to the external medium accommodating space 4, respectively, or may be connected to the same medium accommodating space 4 as shown in fig. 4.
Preferably, the pump assembly may further comprise: a controller 35, the controller 35 may be in communication with the electrically controlled valve 34 and the first one-way pump 33, respectively.
According to the embodiment, the electric control valve 34 and the controller 35 can automatically control the opening and closing of the first one-way pump 33, manual intervention is not needed in the process of simulating respiratory movement, a student can be more concentrated on the confirmation of the trachea and the focus position, and the simulation training effect is improved.
Further optionally, a pressure sensor may be arranged in the container 1 for reading a pressure value of the container 1. The pressure sensor may be communicatively coupled to the controller 35 such that the controller 35 performs pressure adjustments based on the measured pressure values.
Referring to fig. 5, the present embodiment provides a simulated respiration flow of an organ simulation apparatus by taking a pig lung specimen as an example, which includes the following specific steps:
1. an organ simulation apparatus is initialized.
2. The first one-way pump 33 is activated.
3. Repeating the step 1 when the pressure value measured by the pressure sensor is greater than the set value; when the pressure value is less than or equal to the set value, the controller 35 controls the electrically controlled valve 34 to be energized, and the valve is closed at this time. The first one-way pump 33 connected to the container 1 pumps air out of the container 1, the air pressure in the container 1 starts to decrease, and the internal and external pressure difference causes the simulated organ 2 to start to expand.
4. When the simulated organ 2 is completely expanded or nearly completely expanded, the controller 35 controls the electric control valve 34 to be opened, external air enters the container 1, the pressure difference between the inside and the outside of the lung is gradually reduced, and the gas in the lung overflows out of the container 1 through an air passage.
5. And (3) opening the valve again after the pig lung contracts to a certain size, repeating the step (3), and circularly reciprocating in the way to simulate the respiratory motion of the lung.
It is noted that the device may be powered for 8s to 10s (specifically, depending on the volume of the simulated organ 2) for the first time the device is activated. After living tissues such as the pig lung specimen and the like are separated from a living environment, muscle tissues shrink, and the surface relaxes to generate folds, so that the pig lung specimen is expanded to a relatively full initial state after being electrified for a period of time, and further can be better applied to a simulated training scene.
Third embodiment
A third embodiment of the present application also provides an organ simulation apparatus. The organ simulation apparatus of the third embodiment is a further modification of the organ simulation apparatus of the second embodiment; the main improvement is that in the second embodiment of the present application, see fig. 6, in the third embodiment of the present application, the pump assembly may further include: a second one-way pump 36, the second one-way pump 36 being disposed between the electrically controlled valve 34 and the external medium accommodating space 4, and a pump flow direction of the second one-way pump 36 being a direction from the outside to the inside of the container 1 to form a positive pressure in the container 1.
In this embodiment, the controller 35 may be in communication with the electrically controlled valve 34, the first one-way pump 33, and the second one-way pump 36, respectively. The matched electric control valve 34 and the first one-way pump 33 can form negative pressure in the container 1, so that the simulation organ 2 is expanded, and the 'inhaling' motion of the human body is really simulated; the use of an electrically controlled valve 34 and a second one-way pump 36 in conjunction enables a positive pressure to be created within the container 1, thereby causing the simulated organ 2 to contract and truly simulate the "expiratory" movement of the human body. The embodiment can completely simulate the respiratory motion of a human body and help a student to be familiar with the influence of the respiratory motion when the bronchoscope is used, so that the positions of the bronchial branches and the focus can be accurately found, and the training effect is improved.
Wherein, the electrically controlled valve 34 may be an electrically controlled three-way valve, and specifically includes: an inlet a connected to the first one-way pump 33, an outlet B connected to the container 1, and a reversing port C connected to the second one-way pump 36. When the human body's ' inhaling ' movement is simulated, the inlet A and the outlet B are opened, and the first one-way pump 33 can form negative pressure in the container 1, so that the simulated organ 2 is expanded. When the human body 'expiration' movement is simulated, the actuating mechanism can rotate 90 degrees, the valve core is reversed, the reversing port C and the outlet B are opened, and the second one-way pump 36 forms positive pressure in the container 1, so that the simulation organ 2 is contracted. The breathing movement of the human body can be truly simulated by repeating the steps.
The embodiment can adopt a one-way pump with the flow rate of 42L/min under the condition of full power and no load, and the pumped medium can be air. According to the flow curve under different power, the flow of the one-way pump is about 0.21L/s under the half power condition, about 10s is needed for completely expanding the lung by using the connecting pipeline 32 with the length of 6mm, and about 5s is needed for completely emptying the lung. The actual pumping speed is less than the entering speed of the outside air, and the air in the pipe can be similar to liquid. According to p ═ ρ gs/v, tExpansion of/tShrinkage of＝2:1，vExpansion of/vShrinkage of1: 2; the diameter of the bleed tube can be calculated to be about 2.1 mm.
A normal adult breathes for about 5 seconds at a time, and exhales at a rate slightly greater than the inspiration rate. Therefore, in the present embodiment, the simulated inspiration end (the connecting pipe 32 connected with the first one-way pump 33) adopts the pipe with the diameter of 6mm for air intake for 3s, and the simulated expiration end (the connecting pipe 32 connected with the second one-way pump 36) adopts the pipe with the diameter of 4mm for air exhaust for 2s, so as to improve the simulation degree of the bronchoscope training.
Referring to fig. 7, the present embodiment provides an operation procedure of an organ simulation apparatus by taking a pig lung specimen as an example, which is specifically as follows:
1. an organ simulation apparatus is initialized.
2. The first one-way pump 33 and the second one-way pump 36 are started.
3. The pressure value of the container 1 is read. When the pressure value is larger than the set value, repeating the step 1; when the pressure value is less than or equal to the set value, the controller 35 controls the electric control valve 34 to be electrified, the inlet A and the outlet B are opened, the first one-way pump 33 communicated with the container 1 pumps away the medium to the outside of the container 1, the pressure in the container 1 begins to be reduced, and the internal and external pressure difference enables the external air to enter the simulated organ 2 through the air passage, namely the simulated organ 2 begins to expand.
4. Step 3 lasts for 3s, at which time the simulated organ 2 is fully expanded or nearly fully expanded, which can truly and completely simulate the expansion of the lungs during inspiration.
5. The controller 35 controls the electric control valve 34 to open the reversing port C and the outlet B, the second one-way pump 36 communicated with the container 1 replenishes medium into the container 1, the pressure in the container 1 begins to increase, the internal and external pressure difference enables the simulation organ 2 to contract, and the gas in the lung overflows out of the container 1 through an air passage.
6. And step 5 lasts for 2s, at the moment, the simulation organ 2 is partially contracted, and the step can truly and completely simulate the contraction of the lung during expiration.
7. The controller 35 controls the electrically controlled valve 34 to open.
8. And repeating the step 3, and circularly simulating the lung breathing motion with the period of 5 s.
According to the embodiment, the controller 35, the electric control valve 34, the first one-way pump 33 and the second one-way pump 36 are used, so that the medium flowing direction can be accurately and automatically switched, the medium flowing time can be accurately controlled, the human body breathing movement can be truly simulated, and the training effect is improved.

More preferably, the edge of the through hole 141 is surrounded by a plurality of flat protrusions, which are arranged to create a gap between the supporting member 14 and the simulated organ 2, to ensure the medium circulation, so that the pressure difference at each position of the simulated organ 2 is substantially equal, thereby ensuring the uniformity of lung expansion or contraction.
