Description

Technical Field

[0001] The utility model belongs to the technical field of throat surface anesthesia, and in particular relates to a push-pull type expansion device based on throat surface anesthesia. Background Art

[0002] Anesthesia is a comprehensive discipline that includes knowledge from multiple disciplines. Now the scope is wider. It not only meets the requirements of surgery, but also participates in the rescue work of various departments, painless delivery in gynecology, painless abortion, etc. Ensuring that patients can smoothly receive surgical treatment under painless and safe conditions is the basic task of anesthesia clinical practice, but this is only part of the work content of modern anesthesia. Anesthesia work also includes preparation and treatment before and after anesthesia, monitoring and treatment of critically ill patients, emergency resuscitation, pain treatment and other aspects. The scope of work has expanded from the operating room to wards, outpatient clinics, emergency rooms and other places, from clinical medicine to teaching and scientific research. With the increasing expansion of the scope of work and the increasing workload, the Department of Anesthesiology has become an important department in the hospital. Its work is closely related to the diagnosis and treatment of many diseases. For example, when patients undergo tracheoscopic or gastroscopy, they need to spray anesthetic agents on the surface of the throat.

[0003] However, during throat surgery or endoscopic examinations such as laryngoscopy and gastroscopy, the patient's naturally open mouth cannot fully expose the throat, causing most of the sprayed anesthetic to adhere to the mouth, while the anesthetic acting on the throat is minimal, and the anesthetic effect is unsatisfactory. At the same time, the direct introduction of the nozzle will cause the patient to have a foreign body sensation, which is not only prone to nausea, vomiting, etc., but also damages the mucous membrane in the throat, causing the patient's pain to increase and greatly causing discomfort to the patient. In addition, since the amount of anesthetic acting on the throat cannot be determined, it will also bring many risks to subsequent diagnosis and treatment. Utility Model Content

[0004] In view of this, the purpose of the utility model is to provide a push-pull expansion device based on throat surface anesthesia. The upper expansion component and the lower expansion component are adjusted in a push-pull manner to expand the patient's mouth and fully expose the throat to facilitate medical staff to observe and administer medicine; at the same time, with the cooperation of the clamping structure, the patient's mouth can be kept at a certain opening, and the medical staff can free their hands to perform subsequent throat surface anesthesia operations. A single medical staff can perform the task, thereby solving the technical problems described in the background technology.

[0005] The utility model provides a push-pull type expanding device based on throat surface anesthesia, the key of which is that it comprises an upper expanding component and a lower expanding component, the spacing between the upper expanding component and the lower expanding component is adjustable to form a through window with a variable opening between the two; the through window is used for observing the exposure of the human throat on the one hand, and for allowing an anesthetic spraying device to pass through on the other hand; a clamping structure is also arranged between the upper expanding component and the lower expanding component.

[0006] Furthermore, the upper expansion assembly includes an upper connecting plate and an upper expansion plate smoothly connected to the upper connecting plate, and the plate surface of the upper expansion plate has an upwardly raised curvature to adapt to the upper jaw of a human body.

[0007] Furthermore, the lower expansion assembly includes a lower connecting plate and a lower expansion plate smoothly connected to the lower connecting plate, and the end of the lower expansion plate has a downward curvature to press the root of the human tongue.

[0008] Furthermore, the clamping structure includes a guide rail and a movable plate matching the guide rail; an upper flaring component is arranged on the top of the guide rail; a lower flaring component is arranged on the top of the movable plate; and the gap between the upper flaring component and the lower flaring component limited by the guide rail serves as the through window.

[0009] Furthermore, a row of latch teeth are distributed on the back of the movable plate; a mounting plate is also arranged between the guide rails, the mounting plate is provided with an opening, a mounting shell is arranged on the opening, and a button is inserted on the mounting shell; a latch plate is also connected to the inner cavity of the mounting shell through a rotating shaft, one end of the latch plate is close to the button, and the other end is against the cavity wall of the inner cavity of the mounting shell through a spring sheet; in a natural state, the latch plate abuts between two adjacent latch teeth, so that the movable plate can only move downward; when the button is pressed, the latch plate disengages from the latch teeth, so that the movable plate can move up and down.

[0010] Furthermore, a pull ring is provided at the bottom of the movable plate.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] (1) The relative distance between the upper expansion component and the lower expansion component can be adjusted by pushing and pulling, so that the patient's mouth can be opened to fully expose the patient's throat;

[0013] (2) Since the through area of ​​the through window can be changed along with the change of the relative distance between the upper flaring component and the lower flaring component, it can meet the application requirements of different patients and match its opening degree with the opening degree of the patient's mouth, which not only facilitates the medical staff to observe the position of the patient's throat intuitively and comprehensively, but also facilitates the medical staff to quantitatively apply anesthetic drugs to the patient's throat through the through window;

[0014] (3) The through window is used as a channel for the anesthetic spray device to penetrate deeply into the throat during the medication administration process. The movement path of the anesthetic spray device can be limited within a certain range to avoid the anesthetic spray device from colliding with the mucosal tissue during the process of penetrating into the patient's oral cavity. This can not only reduce the risk of oral mucosal damage, but also prevent the occurrence of nausea, vomiting and other phenomena, thereby reducing the patient's foreign body sensation and discomfort.

[0015] (4) The upper flaring component and the lower flaring component can be kept at a predetermined distance by using a clamping structure, so that medical staff do not need to hold the device all the time, which reduces the workload of medical staff. When the flaring is completed, a single medical staff can independently complete the subsequent throat observation and anesthetic quantitative spraying operations, which is more convenient to use and does not require the coordination of multiple people, greatly reducing the occupation of medical resources.

[0016] (5) The upper flaring component and the lower flaring component are assembled separately through a snap-on structure. The two can be disinfected and sterilized separately after disassembly, with fewer dead corners and more thorough disinfection, which can eliminate the risk of cross infection.

DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] In the description of the present invention, it should be understood that the terms "length", "width", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention. In addition, in the description of the present invention, "multiple" means two or more, unless otherwise clearly and specifically defined.

[0030] Figures 1 to 9The first embodiment of the utility model is shown: a push-pull expansion device based on throat surface anesthesia, comprising an upper expansion component 1 and a lower expansion component 2, wherein the spacing between the upper expansion component 1 and the lower expansion component 2 is adjustable to form a through window 3 with a variable opening therebetween; the through window 3 is used on the one hand to observe the exposure of the human throat, and on the other hand to allow an anesthetic spray device to pass through; a clamping structure 5 is also provided between the upper expansion component 1 and the lower expansion component 2.

[0031] See also Figure 3 and Figure 4 In specific implementation, in order to adapt to the contour of the upper jaw of the human body, so as to ensure that the upper flaring component 1 better fits the upper jaw of the patient during use, thereby increasing the effective area, the upper flaring component 1 includes an upper connecting plate 101 and an upper flaring plate 102 smoothly connected to the upper connecting plate 101, and the plate surface of the upper flaring plate 102 has an upwardly raised curvature to adapt to the upper jaw of the human body. Preferably, in order to prevent the root of the tongue from blocking the throat of the patient, the lower flaring component 2 includes a lower connecting plate 201 and a lower flaring plate 202 smoothly connected to the lower connecting plate 201, and the end of the lower flaring plate 202 has a downwardly bent curvature to press the root of the tongue of the human body. This embodiment constrains the shapes of the upper flaring component 1 and the lower flaring component 2 to reduce obstruction while flaring to ensure that the throat of the patient is fully exposed.

[0032] like Figures 3 to 7As shown, the clamping structure 5 includes a guide rail 501 and a movable plate 502 matching the guide rail 501; an upper flaring component 1 is arranged on the top of the guide rail 501; a lower flaring component 2 is arranged on the top of the movable plate 502; and the gap between the upper flaring component 1 and the lower flaring component 2 limited by the guide rail 501 serves as the through window 3. A row of latch teeth 503 are distributed on the back of the movable plate 502; a mounting plate 504 is also arranged between the guide rails 501, the mounting plate 504 is provided with an opening 505, a mounting shell 506 is arranged on the opening 505, and a button 507 is inserted on the mounting shell 506; a latch plate 509 is also connected to the inner cavity of the mounting shell 506 through a rotating shaft 508, one end of the latch plate 509 is close to the button 507, and the other end is against the cavity wall of the inner cavity of the mounting shell 506 through a spring sheet 510; in a natural state, the latch plate 509 abuts between two adjacent latch teeth 503, so that the movable plate 502 can only move downward; when the button 507 is pressed, the latch plate 509 is disengaged from the latch teeth 503, so that the movable plate 502 can move up and down. Specifically, when the movable plate 502 moves downward in a natural state, under the action of the spring sheet 510, the end of the card plate 509 close to the latch tooth 503 can slide along the tooth back of the latch tooth 503, so that the movable plate 502 will not be hindered by the card plate 509 and the latch tooth 503; and when the movable plate 502 wants to move upward in a natural state, the card plate 509 will abut between two adjacent latch teeth 503 to hinder the upward movement of the movable plate 502.

[0033] from Figure 8 and Fig. 9 It can be seen that in order to facilitate medical staff to push and pull the lower flaring assembly 2 , a pull ring 511 is further provided at the bottom of the movable plate 502 .

[0034] To sum up, by adjusting the relative distance between the upper flaring component 1 and the lower flaring component 2 in a push-pull manner, the patient's mouth can be stretched open so that the patient's throat is fully exposed; since the through area of ​​the through window 3 can change with the change of the relative distance between the upper flaring component 1 and the lower flaring component 2, it can meet the application needs of different patients and match its opening degree with the degree of opening of the patient's mouth, which not only facilitates the medical staff to observe the patient's throat position intuitively and comprehensively, but also facilitates the medical staff to quantitatively apply anesthetic drugs to the patient's throat through the through window 3; the through window 3 is used as a channel for the anesthetic spray device to penetrate deeply during the throat administration process, which can limit the movement path of the anesthetic spray device within a certain range to avoid the anesthetic spray device from penetrating into the patient's mouth. The conflict with the mucosal tissue can not only reduce the risk of oral mucosal damage, but also prevent the occurrence of nausea, vomiting and the like, thereby reducing the patient's foreign body sensation and discomfort. The upper flaring component 1 and the lower flaring component 2 can be maintained at a predetermined distance by utilizing the snap-fit ​​structure 5. Medical staff do not need to hold the device all the time, which reduces their workload. After the flaring is completed, a single medical staff can independently complete the subsequent throat observation and quantitative anesthetic spraying operations, which is more convenient to use and does not require the coordination of multiple people, greatly reducing the occupation of medical resources. The upper flaring component 1 and the lower flaring component 2 are assembled in a split manner via the snap-fit ​​structure 5. The two can be disinfected and sterilized separately after disassembly, with fewer dead corners and more thorough disinfection, which can eliminate the risk of cross infection.

[0035] The utility model uses specific examples to illustrate the principle and implementation of the utility model. The above examples are only used to help understand the method and core idea of ​​the utility model. At the same time, for those skilled in the art, according to the idea of ​​the utility model, there will be changes in the specific implementation and application scope. In other words, the content of this specification should not be understood as limiting the utility model.
