Description

Auxiliary device for neck anesthesia nursing

Technical Field

The invention relates to the technical field of medical equipment, in particular to an auxiliary device for neck anesthesia nursing.

Background

The neck anesthesia operation is one of the common operations, it is mainly used for solving the injured problem of the neck, the injured neck mainly includes the operation of diseases such as neck tumor, trauma, congenital malformation, lymph node, thyroid gland and nail-shaped collateral gland, the position of these operations is in front of or inside of the neck, although the range of the operation is not too wide, some operations are not too complicated, but according to its anatomy, physiology, pathological change characteristics of pathological change, need to choose and use the anesthesia rationally, wherein limit, nature benign to pathological change, operation is small, time is short, the patient's whole body situation is good, the function of main viscera is all normal, the vast majority can choose local anesthesia or nerve block to finish the operation; for the patients who do not work properly, such as large operation, wide range, respiratory tract compression symptom, children or special mental stress, etc., the operation needs to be completed under general anesthesia, even complex general anesthesia and general cooling needs to be performed;

however, the instruments used in general anesthesia or local anesthesia are different, most of general anesthesia uses respiratory anesthesia, i.e. some series of instruments such as an anesthesia mask are needed, while local anesthesia uses instruments such as a syringe, which are not the same, so the two instruments are separated in most cases, and need to be taken out separately each time they are selected, which is troublesome, and various unexpected situations also occur in the process of local anesthesia surgery, for example, a patient can not feel pain in the process, but can perceive that a doctor holds an instrument such as a scalpel to slide on the neck of the doctor, so that even before the operation, the doctor can not feel tense, but the condition of heartbeat acceleration and the like can occur, the muscle of the doctor can not contract autonomously, the blood flow rate is accelerated, and the operation process is influenced to some extent, and emergency treatment is needed at this time, the patient is pacified, even other symptoms with the operation may be detected in the operation sometimes, namely, the lesion is enlarged, for example, only a simple excision operation is originally performed, but other lesion sources under the carotid artery of the patient are found in the operation, the operation time is extended and the complexity is high, whether to perform anesthesia again or not and the type of anesthesia need to be selected according to the situation at that time, but it is undeniable that equipment needs to be removed for anesthesia again, but a nurse needs to take a certain time to remove the equipment, and the operation is time-saving, so that the operation is affected;

and the front part of the neck is provided with an important channel of a respiratory system, when general anesthesia operation is performed, the tongue of a patient can contract due to the problems of lying side angle and the like, so that respiratory tract obstruction is caused, and the patient has difficulty in breathing or is suffocated seriously, so measures are taken to ensure the smoothness of the respiratory tract and prevent the respiratory tract obstruction, and when general anesthesia (respiratory anesthesia) is performed, the oxygen output power is kept stable, namely the oxygen flow rate is constant, the air pressure in the anesthesia mask is constant, but as various indexes of the body of the patient can change during anesthesia, if the activity of the lung is reduced, the breathing frequency is reduced, at the moment, if the oxygen is stably output, the inhalation volume of the patient is reduced, the air pressure in the mask is increased, under the action of air pressure difference, the flow of the oxygen entering the human body is increased, and certain damage is caused to the lung of the human body, therefore, when respiratory anesthesia is performed, the air pressure in the mask needs to be regulated and controlled;

Detailed Description

The foregoing and other aspects, features and advantages of the invention will be apparent from the following more particular description of the embodiments of the invention, as illustrated in the accompanying drawings in which reference is made to figures 1 to 18. The structural contents mentioned in the following embodiments are all referred to the attached drawings of the specification.

Exemplary embodiments of the present invention will be described below with reference to the accompanying drawings.

Embodiment 1, this embodiment provides an auxiliary device for nursing and cervical anesthesia, refer to fig. 1, it includes support 1, preferably, support 1 should install four universal wheels below, so facilitate the movement of support 1, and support 1 is provided with the medicinal cupping 4 that is used for the even mixing of medicament at the top, we put the medicament that needs the even mixing in medicinal cupping 4 at the beginning, medicinal cupping 4 is provided with agitating unit, used the even mixing of medicament, after the medicament is mixed, start metering pump 3, begin the circulation of medicament, metering pump 3 is a kind of fluid conveying machinery, its outstanding characteristics are that can keep the constant flow irrelevant with discharge pressure, can accomplish the function of transporting, metering and adjusting simultaneously with metering pump 3, we connect metering pump 3 with external power supply and electric connection has a controller, so can accurate control the metering that the anesthetic flows out from medicinal cupping 4, after the medicament enters the metering pump 3, the medicament flows out from the outlet of the metering pump 3, and as shown in the attached drawing 3, the outlet of the metering pump 3 is connected with a two-way pipeline, the outlet of the pipeline is respectively connected with an anesthesia mode, including respiratory anesthesia (general anesthesia, compound anesthesia, etc.) and injection anesthesia (local anesthesia), according to the selection of the anesthesia mode, the deflection of a partition plate 5 in the pipeline can be controlled by a first driving device, as shown in the attached drawing 3, the partition plate 5 is positioned in the pipeline of a deflection mask 2, namely the inlet of the pipeline of the respiratory anesthesia is blocked, the anesthesia at the moment is injection anesthesia, if the partition plate 5 blocks the pipeline connected with an injector, the anesthesia mode is respiratory anesthesia, and the first driving device in the embodiment can select a motor, then the motor is electrically connected with a controller, so that the opening and closing of the motor and the rotation at a fixed angle can be controlled by the controller, then, the selection of the anesthesia mode is controlled, and after the anesthesia mode is selected, namely the position of the partition plate 5 is determined, the flow direction of the anesthetic is determined;

when the partition plate 5 blocks the inlet of the pipeline communicated with the injector, the anesthesia mode at this time is respiratory anesthesia, the anesthetic enters the atomization device after flowing through the pipeline, the medicament is atomized by the atomization device, and then enters the human body along with oxygen, as shown in fig. 6, the atomization device comprises an atomization tank 25 installed on the support 1, the lower half part of the inner wall of the atomization tank 25 is in an inverted cone structure, so that the medicament gathers towards the center of the atomization tank 25, a separation cavity 26 is formed in the inner bottom wall of the atomization tank 25, the separation cavity 26 is cone-shaped, the upper end cross-sectional diameter is small, the lower end cross-sectional diameter is large, the separation cavity 26 is connected with an air pump providing oxygen at a certain flow rate, so that the flow rate of oxygen at the outlet becomes large due to the narrowing of the outlet after the oxygen enters the separation cavity 26, and under the action of air pressure, the medicament gathers along the separation cavity 26 and flows along with high-speed airflow, then, a partition 28 is arranged on the top wall of the atomizing tank 25 above the outlet of the partition 26, so that the chemicals will collide with the lower end surface of the partition 28 along with the high-speed airflow to become fine droplets, and the chemicals will enter into a circular hole 41 arranged on the upper end of the atomizing tank 25 along with a delivery hole 27 arranged on the outer circumferential surface of the partition 28 after the droplets become droplets, and then enter into a pressure control device for adjusting the air pressure balance in the mask 2 through a pipeline, and under the action of the air pressure difference generated by the air height flow, the chemicals remaining in the pipeline connecting the metering pump 3 and the atomizing tank 25 will gradually enter into the atomizing tank 25, so as to ensure the stable content of the chemicals, it is worth noting here that the pipeline connecting the metering pump 3 and the atomizing tank 25 extends into the atomizing tank 25, and the tail end of the pipeline is located below the upper end of the partition 26, and after the partition 28 is collided with the chemicals for a long time, although the medicament is atomized into mist, the bottom end of the partition 28 inevitably converges into droplets, and if the bottom end of the partition 28 is a horizontal plane, or tapered with the angle pointing downwards, it is possible for drops of water condensed from the agent to drip from the upper outlet of the compartment 26 into the conduit connected to the air pump, so that the content of the medicament in the atomizing tank 25 is reduced, the anesthetic effect is affected, therefore, the bottom end of the partition cylinder 28 is designed to be conical with the sharp angle upwards, and the diameter of the cross-section of the bottom end of the partition 28 is larger than the diameter of the cross-section of the upper end of the compartment 26, the drops of medicine thus coagulated drip along the bottom end of the conical partition 28 into the nebulizing canister 25, further can be atomized again, so that the content of the medicament is not influenced, and the anesthesia effect is further influenced, after the anesthetic is atomized, the anesthetic is transported into the anesthetic mask 2 through a pipeline and then is breathed and absorbed by a patient;

referring to fig. 17, the outer edge face of the anesthetic mask 2 contacting the face of the human body is provided with a latex ring with certain elasticity, so that the patient can be attached to the face of the patient after wearing the anesthetic mask 2, the anesthetic cannot be leaked, the metering of the anesthetic cannot be influenced, the anesthetic cannot be leaked, the medical staff is not injured or the operation of the medical staff cannot be influenced, in addition, the respiratory anesthesia is general anesthesia, the patient is unconscious and in a coma state, the heart, the lung and the like are in a weak operation state, the tongue and the like are not controlled by the patient, if the tongue contracts inwards to block the exhalation pipeline, the respiratory tract is blocked, the patient is difficult or seriously suffocated, the respiratory tract is blocked, the anesthetic can also be influenced to enter the human body through the trachea, and therefore, referring to fig. 1 and fig. 17, a tongue depressor 6 is arranged at a position, corresponding to the mouth, in an anesthesia mask 2, so that when a patient wears the mask 2, the tongue depressor 6 presses the tongue first, after the mask 2 is fixed on the face of the patient, the tongue depressor 6 is relatively fixed, the tongue is pressed and cannot shrink after anesthesia, but the depths of the oral cavities of different patients are different, so that the tongue depressor 6 is made into a telescopic structure for straightening the high usability, namely, an extension plate with a certain length is arranged in the mask 2, the extension plate is of a hollow opening structure, the tongue depressor 6 is slidably arranged in the extension plate, the extension length of the tongue depressor 6 is adjusted according to the actual condition of the patient, in order to adjust the extension length of the tongue depressor 6, a pull rope 7 is arranged at one end, away from the patient, of the tongue depressor 6, and the mask 2 (the bottom end of the extension plate) are connected with a first spring, if no other external force is applied to the pull rope 7, when the first spring is in a normal telescopic state, the tongue depressor 6 is in a maximum extending state, one end of the pull rope 7 extending out of the mask 2 is connected with a grooved pulley 8 rotatably mounted on the mask 2, so that the pull rope 7 can be rotated to roll the pull rope 7 to drive the tongue depressor 6 to contract, and then the adjustment problem of the tongue depressor 6 is realized, but the grooved pulley 8 needs to be limited after rotation, otherwise, the tongue depressor 6 can still reset under the action of the first spring, therefore, a ratchet 9 coaxially rotating with the grooved pulley 8 is arranged on the mask 2, a pawl 10 matched with the ratchet 9 is further arranged, a spring piece is connected between the pawl 10 and the mask 2, so that under the action of the ratchet 9, the pawl 10 and the spring piece, the grooved pulley 8 is limited, namely, the tongue depressor 6 is contracted by rotating the grooved pulley 8, and the pawl 10 slides on, when the rotation of the sheave 8 is stopped, the pawl 10 again abuts against the tooth root of the ratchet wheel 9, so that the ratchet wheel 9 is restricted from rotating, and thus the sheave 8 is also restricted, and when the use is finished, namely, after the operation is finished, the user only needs to dial the pawl 10 after taking off the mask 2, then the tongue depressor 6 resets again under the action of the first spring, then the extension length of the tongue depressor 6 needs to be adjusted again when the user uses the mask next time, and the inlet for inputting gas and medicament on the mask 2 is positioned above the tongue depressor 6, and in addition, the position of the mask 2 below the tongue depressor 6 is provided with an exhaust hole, the exhaust hole is connected with a waste treatment device and used for treating waste gas exhaled by a patient, a first one-way valve 11 is arranged in the exhaust hole, fluid can only flow along the inlet, and the medium at the outlet cannot flow back, so that the waste gas exhausted by the patient can only be exhausted without flowing back;

under normal conditions, after the medicament is atomized in the atomizing device, the medicament flows into the mouth mask 2 along with air and then enters the body of a patient, but during anesthesia, the activity of the lung is low, so that the amount of oxygen (including the atomized medicament) entering the body by the patient breathing independently is low, the oxygen is in a stable output state, then, because the input amount is larger than the intake amount, redundant gas is accumulated in a closed cavity formed by the mouth mask 2 and the face of the patient, the air pressure in the space gradually rises, under the action of the air pressure difference, a part of gas passively enters the body of the patient to reduce a part of pressure, but along with the stable output of the oxygen, the internal air pressure also gradually rises, when the air pressure in the mouth mask 2 rises to a certain value, certain damage is caused to the organs of the human body, and therefore, the internal air pressure of the mouth mask 2 needs to be regulated and controlled, therefore, a pressure control device is provided between the atomizing device and the mask 2, as shown in fig. 4, fig. 7, fig. 9 and fig. 18, the pressure control device includes a regulating box 12 communicated with a circular hole 41 provided on the atomizing tank 25, and a partition is provided in the regulating box 12, the partition divides the inner cavity of the regulating box 12 into an upper part and a lower part, but the two parts are still in a communicated state, the partition and the bottom wall of the regulating box 12 form a regulating chamber 13, and a regulating valve 15 is slidably mounted at the opening of the regulating chamber 13, the specific structure of the regulating valve 15 is shown in fig. 18, one end of the regulating valve 15 extending into the regulating chamber 13 is connected with the regulating chamber 13 by a second spring, under the action of the second spring, the regulating valve 15 is located at the opening of the regulating chamber 13, and the other side of the regulating valve 15 is not contacted with the inner wall of the regulating box 12 (as shown in fig. 4), under the action of the regulating valve 15, the regulating cavity 13 forms a relatively closed hair-generating cavity, and the upper and lower end surfaces of the regulating cavity 13 are respectively provided with a vent hole 14, wherein the vent hole 14 on the lower end surface of the regulating cavity 13 is communicated with the round hole 41, so that atomized medicine drops firstly enter the regulating cavity 13, the vent hole 14 on the upper end surface is communicated with the cavity on the upper part of the regulating box 12, so that the medicine can enter the cavity on the upper part of the regulating box 12 from the regulating cavity 13, the cavity on the upper part of the regulating box 12 is communicated with the anesthesia mask 2, so that the medicine can enter the space formed by the oral mask 2 and the face of a patient, when the air pressure in the space gradually rises, the air pressure in the cavity on the upper part of the regulating box 12 communicated with the mask 2 also rises, so that the regulating box 12 is pressed to slide in the regulating cavity 13, and the higher the air pressure is, the sliding distance is larger, and in the sliding process of the regulating valve 15, the vent holes 14 are gradually shielded, so that the area of the vent holes 14 leaking is smaller and smaller, and thus the flow rate of the gas entering the adjusting cavity 13 is reduced, that is, the input amount of the gas is reduced, and the air pressure in the mask 2 is relieved to an equal extent, preferably, in the embodiment, two vent holes 14 are arranged on the upper wall and the lower wall of the adjusting cavity 13, so that the adjusting valve 15 shields one vent hole 14 first and then shields the other vent hole 14 in the sliding process, but it should be noted that the vent holes 14 cannot be completely shielded to prevent the patient from being unable to take enough oxygen, therefore, we have an adjusting button 16 arranged on the side of the adjusting valve 15 away from the adjusting cavity 13, and the end of the adjusting button 16 extending out of the adjusting box 12 is provided with a circular truncated cone, and the diameter of the cross section of the circular cone is larger than that the adjusting button 16 and the adjusting, the sliding fit position of the adjusting button 16 and the adjusting box 12 should have a good sealing condition, in the sliding process of the adjusting valve 15, after the circular truncated cone contacts the side wall of the adjusting box 12, even if the air pressure continues to increase, the adjusting valve 15 cannot continue to move, and at this time, the vent hole 14 far away from the adjusting valve 15 is not completely shielded, so that oxygen is ensured to pass through, and the existence of the adjusting button 16 can enable medical staff to autonomously press the adjusting button 16 when the medical staff detects that the overhigh air pressure in the mask 2 is harmful to a patient, so that the adjusting valve 15 is pushed into the adjusting cavity 13 to shield the vent hole 14 for emergency pressure relief, but even if the flow of the oxygen is
