Description

Technical Field

[0001] The utility model belongs to the technical field of throat surface anesthesia, and in particular relates to a hand-held expanding device for 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 hand-held expanding device for throat surface anesthesia. The upper expanding component and the lower expanding component are adjusted by hand 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 hand-held expanding device for throat surface anesthesia, the key of which is that it comprises an upper expanding component and a lower expanding component hinged to the upper expanding component, a through window is reserved 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 for limiting the hinge angle of the upper expanding component and the lower expanding component is also arranged between the upper expanding component and the lower expanding component.

[0006] Furthermore, the upper flaring assembly includes a first handle and an upper flaring plate arranged on the top of the first handle, and the through window is opened on the first handle below the upper flaring plate.

[0007] Furthermore, the plate surface of the upper expansion plate has an upwardly raised curvature to adapt to the upper jaw of a human body.

[0008] Furthermore, the lower flaring assembly includes a second handle and a lower flaring plate arranged on the top of the second handle, and the second handle is hinged to the first handle below the through window through a rotating shaft.

[0009] Furthermore, the end of the lower expansion plate has a downward curvature to press the root of the human tongue.

[0010] Furthermore, the clamping structure includes an arc-shaped guide plate arranged at the bottom of the second handle and matching its rotation path, the arc-shaped guide plate is provided with a guide groove, and a plurality of locking teeth are distributed on the groove wall of the guide groove; a clamping piece is hinged on the first handle through a pin shaft, one end of the clamping piece cooperates with the locking teeth, and the other end is provided with a finger pressure plate; a first spring sheet is also provided between the finger pressure plate and the first handle; in a natural state, the clamping piece abuts between two adjacent locking teeth, so that the angle between the first handle and the second handle can only be increased; when the finger pressure plate is pressed, the clamping piece disengages from the locking teeth, so that the angle between the first handle and the second handle can be increased or reduced.

[0011] Furthermore, a second spring sheet is provided between the first handle and the second handle.

[0012] Furthermore, lighting lamp beads are distributed on the through window, and a lighting switch is also provided between the first handle and the second handle. The lighting switch is connected to the control circuit of the lighting lamp beads, and when the angle between the first handle and the second handle reaches a predetermined threshold, the lighting switch can turn on the lighting lamp beads.

[0013] Furthermore, a grip is also provided on the second handle.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] (1) By manually adjusting the hinge angles of the upper and lower expansion components, the patient's mouth can be opened to fully expose the patient's throat;

[0016] (2) 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.

[0017] (3) The upper and lower flaring assemblies can be kept at a predetermined hinge angle by using a clamping structure, so that medical staff do not need to hold the device all the time, which reduces their workload. 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, thus greatly reducing the occupation of medical resources.

[0018] (4) With the cooperation of the lamp beads and the lighting switch, the lighting can be automatically turned on when the upper flaring assembly and the lower flaring assembly reach a predetermined opening, 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.

[0030] 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.

[0031] 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.

[0032] Figures 1 to 9The first embodiment of the utility model is shown: a hand-held expanding device for throat surface anesthesia, the key of which is: it includes an upper expanding component 1 and a lower expanding component 2 hinged to the upper expanding component 1, and a through window 3 is reserved between the two. The through window 3 is used for observing the exposure of the human throat on the one hand, and for allowing an anesthetic spraying device 4 to pass through on the other hand; a clamping structure 5 is also provided between the upper expanding component 1 and the lower expanding component 2 for limiting the hinge angle of the two.

[0033] See also Figure 2 and Figure 3 In a specific implementation, the upper flaring assembly 1 includes a first handle 101 and an upper flaring plate 102 disposed on the top of the first handle 101, and the through window 3 is provided on the first handle 101 below the upper flaring plate 102. In order to adapt to the contour of the upper jaw of the human body, so as to ensure that the upper flaring plate 102 better fits the upper jaw of the patient during use, thereby increasing the effective area, the plate surface of the upper flaring plate 102 has an upwardly raised curvature to adapt to the upper jaw of the human body. The lower flaring assembly 2 includes a second handle 201 and a lower flaring plate 202 disposed on the top of the second handle 201, and the second handle 201 is hinged to the first handle 101 below the through window 3 through a rotating shaft 203. Preferably, in order to prevent the root of the tongue from blocking the throat of the patient, the end of the lower flaring plate 202 has a downwardly curved curvature to press the root of the human tongue. In this embodiment, by constraining the shapes of the upper expanding plate 102 and the lower expanding plate 202, shielding is reduced while expanding the mouth, so as to ensure that the patient's throat is fully exposed.

[0034] like Figures 4 to 5As shown, the clamping structure 5 includes an arc guide plate 501 arranged at the bottom of the second handle 201 and matching its rotation path, the arc guide plate 501 is provided with a guide groove 502, and a plurality of latch teeth 503 are distributed on the groove wall of the guide groove 502; a clamping member 505 is hinged on the first handle 101 through a pin shaft 504, one end of the clamping member 505 cooperates with the latch teeth 503, and the other end is provided with a finger pressure plate 506; a first spring sheet 507 is also provided between the finger pressure plate 506 and the first handle 101; in a natural state, the clamping member 505 abuts between two adjacent latch teeth 503, so that the angle between the first handle 101 and the second handle 201 can only be increased; when the finger pressure plate 506 is pressed, the clamping member 505 disengages from the latch teeth 503, so that the angle between the first handle 101 and the second handle 201 can be increased or decreased. Specifically, when the angle between the first handle 101 and the second handle 201 increases in the natural state, under the action of the first spring sheet 507, the end of the clamping member 505 close to the latching tooth 503 can slide along the tooth back of the latching tooth 503, so that the first handle 101 and / or the second handle 201 will not be hindered by the clamping member 505 and the latching tooth 503 during rotation; and when the first handle 101 and the second handle 201 want to reduce the angle in the natural state, the clamping member 505 will abut between two adjacent latching teeth 503 to hinder the movement tendency of the first handle 101 and / or the second handle 201 to rotate toward each other. Preferably, a limited position passage opening 508 is also provided on the first handle 101, and the limited position passage opening 508 is used for allowing the arc guide plate 501 to pass through on the one hand, and for limiting the movement path of the arc guide plate 501 on the other hand.

[0035] from Figure 2 and Figure 4 It can be seen that in order to achieve the rapid reset of the first handle 101 and / or the second handle 201, a second spring sheet 6 is further provided between the first handle 101 and the second handle 201. It should be noted that when the clamping member 505 abuts between two adjacent latch teeth 503, the force that prevents the first handle 101 and / or the second handle 201 from increasing the included angle should be greater than the reset force of the first handle 101 and / or the second handle 201. Even if the first handle 101 and / or the second handle 201 is forced to reset by an external force, the surface wall of the first handle 101 can also abut against the front end of the clamping member 505 to further limit the reset of the first handle 101 and / or the second handle 201, thereby improving the stability of the structure.

[0036] Please refer to Figures 6 to 8In a specific implementation, the through window 3 is provided with a lighting lamp bead 7, and a lighting switch 8 is further provided between the first handle 101 and the second handle 201. The lighting switch 8 is connected to the control circuit of the lighting lamp bead 7, and when the angle between the first handle 101 and the second handle 201 reaches a predetermined threshold, the lighting switch 8 can turn on the lighting lamp bead 7. Specifically, the lighting switch 8 includes a positive pole 801 and a negative pole 802 that move with the first handle 101, and an elastic conductive member 803 that moves with the second handle 201. The positive pole 801 is connected to the positive pole of the lighting lamp bead 7 through a battery, and the negative pole 802 is connected to the negative pole of the lighting lamp bead 7. When the first handle 101 and the second handle 201 reach a predetermined angle, the elastic conductive member 803 can contact the positive pole 801 and the negative pole 802 to turn on the control circuit of the lighting lamp bead 7. Preferably, the control circuit and the battery are both arranged inside the first handle 101.

[0037] As 3, Figure 4 and Fig. 9 As shown, in order to facilitate the operator to hold, a grip 9 is also provided on the second handle 201.

[0038] In summary, by adjusting the hinge angles of the upper flaring component 1 and the lower flaring component 2 by hand, the patient's mouth can be opened to fully expose the patient's throat; the through window 3 is used as a channel for the anesthetic spray device 4 to penetrate deeply during the throat administration process, which can limit the movement path of the anesthetic spray device 4 within a certain range to avoid the anesthetic spray device 4 from conflicting with the mucosal tissue during the process of penetrating into the patient's mouth. This 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 clamping structure 5 can be used to maintain the upper flaring component 1 and the lower flaring component 2 at a predetermined hinge angle, so that the medical staff does not need to hold the device all the time, which reduces the workload of the medical staff. 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 cooperation of multiple people, greatly reducing the occupation of medical resources. With the cooperation of the lamp beads and the lighting switch 8, the lighting can be automatically turned on when the upper flaring component 1 and the lower flaring component 2 reach a predetermined opening, which not only facilitates the medical staff to observe the patient's throat position intuitively and comprehensively, but also helps the medical staff to quantitatively apply anesthetic drugs to the patient's throat through the through window 3.
