Description

Technical Field

[0001] This utility model belongs to the field of medical device technology, specifically relating to an easily adjustable spray anesthesia device. Background Technology

[0002] Anesthesia means using drugs or other methods to temporarily remove sensation from the patient's whole body or part of the body to achieve painless surgical treatment. In clinical practice, pharyngeal and tracheal surface anesthesia is often performed before endotracheal intubation to reduce the stimulation of intubation to the patient.

[0003] In the prior art, such as the Chinese utility model patent document with authorization announcement number CN221332406U, a clinical anesthetic spray device is disclosed. By rotating the lead screw, the piston block can be moved inside the drug storage tube, which can compress the drug liquid inside the drug storage tube and make it enter the nozzle through the connecting tube to achieve the spraying effect of anesthetic liquid. Although this method can control the amount of drug sprayed, the drug delivery speed is relatively slow by rotating the lead screw by hand, which takes a lot of time. Moreover, it is difficult to control the device to shake constantly during the drug delivery process, which causes discomfort to the patient and also affects the accuracy of the drug delivery position.

[0004] Therefore, there is a need to design an easily adjustable spray anesthesia device that facilitates rapid and accurate administration of anesthetic spray, reduces patient discomfort, and solves the current technical problems. Summary of the Invention

[0005] In view of the shortcomings of the existing technology, the present invention provides an adjustable spray anesthesia device that facilitates rapid and accurate administration of anesthetic spray, reduces patient discomfort, and is easy to adjust.

[0006] The technical solution of this utility model is as follows: an easily adjustable spray anesthesia device, including a drug reservoir, a scale on the outside of the drug reservoir, a drug delivery tube at one end of the drug reservoir, a nozzle at the end of the drug delivery tube opposite to the drug reservoir, a groove on the outside of the drug delivery tube, a piston inside the drug reservoir, a push rod fixedly mounted on the end of the piston opposite to the drug delivery tube, a push plate fixedly mounted on the end of the push rod opposite to the piston, pull plates symmetrically mounted on the end of the drug reservoir opposite to the drug delivery tube, and an adjustable quantitative limiting mechanism on the outside of the drug reservoir; the adjustable quantitative limiting mechanism has an indicator ring slidably fitted on the outside of the drug reservoir, a limiting rod rotatably mounted on the outside of one end of the indicator ring parallel to the axial direction of the drug reservoir, the limiting rod being threadedly connected to the outside of the end of the drug reservoir, and the end of the limiting rod opposite to the indicator ring corresponding to the push plate.

[0007] A support base is fixedly installed on the outer side of the end of the drug storage cylinder opposite to the drug delivery tube, and the limiting rod is connected to the internal thread of the support base.

[0008] A hand-tightening lever is concentrically fixed at one end of the limiting rod opposite to the indicator ring.

[0009] The outer side of the hand-twisting rod has a circular array of anti-slip ridges, and the anti-slip ridges are an integral part of the hand-twisting rod.

[0010] An adjustment tube is fixedly installed inside the bite groove, and the inside of the adjustment tube is threadedly connected to the drug delivery tube.

[0011] The regulating tube has an internal threaded hole inside, and the administration tube has an adjusting section on the outside, which is an external thread that matches the internal threaded hole.

[0012] The beneficial effects of this utility model are as follows: In this utility model, the anesthetic agent is drawn into the inside of the storage cylinder by the piston pulled by the push plate. The position of the limiting rod is adjusted so that one end of it abuts against the push plate. At this time, the scale value on the side of the indicator ring near the nozzle corresponds to the first scale value on the storage cylinder. According to the dosage, the dosage is subtracted from the first scale value to obtain the second scale value. The position of the limiting rod is adjusted so that the indicator ring corresponds to the second scale value. At this time, when the set dosage is reached, the limiting rod restricts the push plate from moving further, realizing the rapid and accurate quantitative administration of anesthetic spray. Moreover, it is not easy to shake during the push administration process, reducing patient discomfort. Attached Figure Description

[0017] like Figure 1 As shown, the easily adjustable spray anesthesia device includes a drug reservoir 1, with graduations 11 on the outside of the reservoir 1. A drug delivery tube 2 is attached to one end of the reservoir 1, with a nozzle 3 at the end of the drug delivery tube 2 facing away from the reservoir 1. A groove 4 is provided on the outside of the drug delivery tube 2. A piston is located inside the reservoir 1, with a push rod 5 fixedly attached to the end of the piston facing away from the drug delivery tube 2. A push plate 6 is fixedly attached to the end of the push rod 5 facing away from the piston. Pull plates 7 are symmetrically arranged on the end of the reservoir 1 facing away from the drug delivery tube 2. An adjustable quantitative limiting mechanism 8 is located on the outside of the reservoir 1. The adjustable quantitative limiting mechanism 8 has an indicator ring 83 that slides onto the outside of the reservoir 1. A limiting rod 81, parallel to the axial direction of the reservoir 1, is rotatably mounted on the outside of one end of the indicator ring 83. 1. The end of the drug reservoir 1 is threadedly connected to the outer side of the end of the limiting rod 81, which is opposite to the indicator ring 83 and corresponds to the push plate 6. In this embodiment, the anesthetic is drawn into the inside of the drug reservoir 1 by the piston pulled by the push plate 6. The position of the limiting rod 81 is adjusted so that one end of it abuts against the push plate 6. At this time, the side of the indicator ring 81 near the nozzle corresponds to a scale value on the drug reservoir 1 as the first scale value. According to the dosage, the first scale value is subtracted from the dosage to obtain the second scale value. The position of the limiting rod 81 is adjusted so that the indicator ring 83 corresponds to the second scale value. At this time, when the set dosage is reached, the limiting rod 81 restricts the push plate 6 from continuing to move, so as to achieve rapid and accurate quantitative drug delivery of anesthetic spray. Moreover, it is not easy to shake during the drug delivery process, reducing patient discomfort.

[0018] In some embodiments, a support base 82 is fixedly provided on the outer side of the end of the medicine storage cylinder 1 opposite to the drug delivery tube 2. A limiting rod 81 is internally threaded to the support base 82. The limiting rod 81 is a screw. The support base 82 has an internal threaded channel that matches the screw. By rotating the limiting rod 81, the limiting rod 81 can be driven to move along its axial direction through the threaded mechanism between it and the support base 82. Specifically, the support base 82 and the medicine storage cylinder 1 are connected as an integral structure.

[0019] In some embodiments, a hand-tightening rod 85 is concentrically fixed on one end of the limiting rod 81 away from the indicator ring 83. The diameter of the hand-tightening rod 85 is larger than that of the limiting rod 81, and the hand-tightening rod 85 is easy to turn, thereby driving the limiting rod 81 to rotate.

[0020] In some embodiments, the outer side of the hand-tightening lever 85 is provided with anti-slip protrusions 86 arranged in a circumferential array. The anti-slip protrusions 86 are integral with the hand-tightening lever 85. The anti-slip protrusions 86 can increase the friction between the hand-tightening lever 85 and the hand, and prevent slippage when turning the hand-tightening lever 85.

[0021] In some embodiments, such as Figure 2 As shown, an adjusting tube 41 is fixedly installed inside the bite groove 4. The inside of the adjusting tube 41 is threadedly connected to the drug delivery tube 2. By rotating the bite groove 4 relative to the drug delivery tube 2, the threaded structure between the adjusting tube 41 and the drug delivery tube 2 can drive the bite groove 4 to move and adjust along the axial direction of the drug delivery tube 2. This adjusts the length of the drug delivery tube 2 that extends into the patient's mouth when the patient bites down on the bite groove 4. During use, the position of the bite groove 4 can be adjusted according to the different drug delivery depths required by different patients. Specifically, the bite groove 4 is made of medical silicone material, and its upper and lower sides have grooves that match the curvature of human teeth. The adjusting tube 41 is a rigid plastic tubular structure that is fixedly bonded inside the bite groove 4.

[0022] In some embodiments, the regulating tube 41 has an internal threaded hole inside, and the administration tube 2 has an regulating section 21 on the outside, the regulating section 21 being an external thread that matches the internal threaded hole.
