Description

Technical Field

[0001] The utility model relates to the technical field of medical auxiliary appliances, in particular to an insulin sprayer. Background Art

[0002] In the treatment of diabetic patients, insulin is usually injected into the patient's body to promote the conversion of glucose into fat and protein needed by the human body and help diabetic patients control their blood sugar levels. In the prior art, syringes are divided into needle insulin syringes and needle-free insulin sprayers. In order to avoid needle holes and pain, needle-free insulin sprayers are widely used. By pressing the injection button, the internal pressure device generates high pressure, pushing the liquid in the medicine tube to form a liquid column through the micropores, instantly penetrating the skin, and reaching the subcutaneous diffused drug delivery. However, when the patient's blood sugar concentration rises above the normal range, it will cause symptoms such as weakness in the patient's limbs and drowsiness. Since the injection button controls the release of internal pressure, the required pressing force is large, so that the patient does not have enough strength to press the injection button, and needs medical staff or family members to inject it, which makes the patient unable to be self-sufficient when needed, and has great limitations. Utility Model Content

[0003] In view of the deficiencies in the prior art, the utility model provides an insulin sprayer, which has the advantages of being self-sufficient when the patient needs to use it, and having both electric control and manual control, and is highly applicable. It solves the problem in the prior art that when the patient's blood sugar concentration rises above the normal range, it will cause the patient to have symptoms such as weakness in the limbs and drowsiness. Since the injection button controls the release of internal pressure, the required pressing force is relatively large, so the patient does not have sufficient strength to press the injection button, and needs medical staff or family members to inject them, resulting in the patient's inability to be self-sufficient when needed and having great limitations.

[0004] In order to solve the above technical problems, the utility model provides the following technical solutions:

[0005] An insulin sprayer comprises a sprayer body for spraying insulin, one end of the sprayer body is provided with an auxiliary mechanism for being in close contact with the patient's skin, the other end of the sprayer body is provided with an adjustment mechanism for simply applying pressure to an injection button, the adjustment mechanism comprises a fixing ring fixedly connected to one end of the sprayer body, one side of the fixing ring is provided with a circular ring groove, one side of the circular ring groove is provided with a threaded groove, a threaded thin wall is threadedly connected in the threaded groove, one side of the threaded thin wall is fixedly connected with a fixed gear ring, a pressure plate is fixedly connected to the fixed gear ring, one side of the fixing ring is fixedly connected with a connecting shell, one side of the fixing ring is fixedly connected with a protective shell, and the side of the fixing ring close to the fixed gear ring is rotatably connected with a driving gear meshing with the fixed gear ring.

[0006] Preferably, a micro motor for controlling the rotation of the driving gear is fixedly mounted in the protective shell, and a touch switch electrically connected to the micro motor is fixedly mounted on the sprayer body.

[0007] Preferably, the auxiliary mechanism includes a connecting ring fixedly connected to one end of the sprayer body, a plurality of blocks are fixedly connected to one side of the connecting ring, a connecting shell is clamped to one side of the connecting ring, a groove engaged with the plurality of blocks is opened on one side of the connecting shell, and a circular ring plate is fixedly connected to the other side of the connecting shell.

[0008] Preferably, the driving gear of the connecting sleeve is in the shape of a cylindrical gear, a circular hole a is provided on the pressure plate, and a circular hole b is provided on the connecting sleeve.

[0009] Preferably, a laminating film is detachably mounted on one side of the annular plate.

[0010] Preferably, a dust cover is detachably mounted on one end of the sprayer body close to the connecting ring.

[0011] By means of the above technical solution, the utility model provides an insulin sprayer, which has at least the following beneficial effects:

[0012] 1. The utility model provides an adjustment mechanism so that the device can electrically press the injection button, thereby reducing the effort required by the patient when using the device. The micromotor is regulated by the touch card switch, so that the micromotor drives the driving gear to rotate, thereby causing the fixed gear ring to drive the threaded thin wall to rotate in the thread groove, so that the pressure plate applies pressure to the injection button, thereby completing the injection of insulin, allowing the patient to be self-sufficient when needed. At the same time, the button can still be manually pressed through the circular holes a and b, thereby improving the applicability of the device.

[0013] 2. The utility model provides an auxiliary mechanism so that the device can be in close contact with the patient's skin surface during injection. The circular plate prevents the injection port of the device from tilting, so that the sprayer body can be injected stably. At the same time, the contact between the patient and the circular plate is more comfortable under the action of the bonding film, thereby ensuring the use effect of the device.

[0023] In order to solve the problem in the prior art that when the patient's blood sugar concentration rises above the normal range, the patient will suffer from symptoms such as weakness in the limbs and drowsiness. Since the injection button controls the release of internal pressure, the pressing force required is large, so the patient does not have enough strength to press the injection button, and needs medical staff or family members to inject him, which makes the patient unable to be self-sufficient when he needs to use it. The limitation is large. Please refer to Figure 1-Figure 4 As shown, an embodiment provided by the utility model;

[0028] Specifically, a fitting film is detachably installed on one side of the circular plate 204. The fitting film may be made of rubber, latex or other materials, which can fit the patient's skin and improve the use effect. A dust cover is detachably installed on one end of the sprayer body 1 close to the connecting ring 201, so that the device can avoid dust accumulation and contamination at the injection port when it is normally placed.
