Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical device technology, and in particular to a sprayer. Background Technology
[0002] As is well known, if oral medications are ineffective in treating nasal lesions, topical sprays are generally used in clinical practice to achieve better results. The inside of the nose is narrow and deep, and the nasal hairs vary greatly among different patients. When using traditional sprayers, if the operator presses too fast, the patient is prone to a stress response, causing the patient to sneeze and wasting the medication. Utility Model Content
[0003] The purpose of this invention is to address the shortcomings of existing sprayers, where patients are prone to stress reactions when the operator presses the button too quickly, resulting in sneezing and wasting medication. This invention provides a new type of sprayer.
[0004] To achieve the above objectives, the present invention adopts the following technical solution:
[0005] Design a pesticide sprayer, including a cartridge, one end of which has a channel, the channel being cylindrical, a baffle strip inside the channel, a spray assembly connected to the bottom of the channel, a movable rod slidably mounted on the baffle strip, and sealing blocks at both ends of the movable rod, one end of which has an elastic element connected to the baffle strip, and a squeezing mechanism at the other end of the cartridge, with a pressing block at the squeezing mechanism, wherein in one working state, one side of one of the sealing blocks is attached to one end of the channel.
[0006] Preferably, the extrusion mechanism includes a sleeve threadedly connected inside the cartridge, a piston slidably disposed inside the sleeve, a connecting rod mounted on one end of the piston, and the pressing block mounted on one end of the connecting rod.
[0007] Preferably, a retaining block is mounted on one end of the sleeve via a bearing.
[0008] Preferably, one end of the card block is equipped with a long strip, one end of which extends to the cartridge and has a groove.
[0009] Preferably, the strip is provided with a graduated groove.
[0010] Preferably, the elastic element is a cylindrical spring, and the elastic element is sleeved on the moving rod.
[0011] Preferably, the spray assembly is provided with filter cotton.
[0012] The sprayer proposed in this utility model has the following advantages: After applying pressure to the pressing block to activate the pressing mechanism, the liquid in the cartridge will squeeze one of the sealing blocks, thereby connecting the channel with the spray assembly. This allows the spray assembly to spray the patient's nostrils. If the operator presses too high a pressure, the flow rate of the liquid in the cartridge will also increase, causing the other sealing block to seal one end of the channel, preventing the device from spraying. This ensures that the operator does not press too high a pressure during the nostril spraying process, making it less likely for the patient to experience an emergency or sneeze, thus reducing the possibility of wasting medication.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0020] Example 1: Refer to Figure 1-5A pesticide sprayer includes a cartridge 1, a channel 2 at one end of the cartridge 1, the channel 2 being cylindrical, a baffle 3 inside the channel 2, a spray assembly 4 connected to the bottom of the channel 2, a filter cotton 16 provided at the spray assembly 4, a movable rod 5 slidably mounted on the baffle 3, and sealing blocks 6 at both ends of the movable rod 5, one end of one of the sealing blocks 6 being provided with an elastic element 7, which is a cylindrical spring, sleeved on the movable rod 5, and one end of the elastic element 7 being connected to the baffle 3, and a squeezing mechanism at the other end of the cartridge 1, with a pressing block 8 provided at the squeezing mechanism, wherein in one working state, one side of one of the sealing blocks 6 is attached to one end of the channel 2.
[0021] Combined with appendix Figure 3-5 It can be seen that in the initial state, under the elastic force of the elastic element 7, one end of the sealing block 6 abuts against one end of the cartridge 1, so that the channel 2 on the cartridge 1 is separated from the spray assembly 4. There is a gap between the other sealing block 6 and the channel 2. When the pressure of the liquid inside the cartridge 1 increases, the sealing block 6 abutting against one end of the cartridge 1 will move, thereby connecting the channel 2 with the spray assembly 4, so that the device can work. Moreover, if the flow speed of the cartridge is too fast, the sealing block 6 at the spray assembly 4 will move away from the channel 2 and pull the moving rod 5 so that the other sealing block 6 seals one end of the channel 2 again.
[0022] After the spray assembly 4 is directed towards the patient's nostrils, pressure is applied to the pressing block 8 to activate the pressing mechanism. The liquid inside the cartridge 1 will squeeze one of the sealing blocks 6, thereby connecting the channel 2 with the spray assembly 4. This allows the spray assembly 4 to spray the patient's nostrils. If the operator presses too hard, the flow rate of the liquid inside the cartridge 1 will also increase, causing the other sealing block 6 to seal one end of the channel 2, preventing the device from spraying. This prevents the operator from pressing too quickly during the nostril spraying process, making it less likely for the patient to experience an emergency or sneeze, thus reducing the possibility of medication waste.
[0023] Example 2: An optimization based on Example 1, with reference to... Figure 1-5 The extrusion mechanism includes a sleeve tube 9 threadedly connected to the cartridge 1. A piston 10 is slidably disposed inside the sleeve tube 9. A connecting rod 11 is installed at one end of the piston 10. A pressing block 8 is installed at one end of the connecting rod 11. A locking block 12 is installed at one end of the sleeve tube 9 via a bearing. A long strip 13 is installed at one end of the locking block 12. One end of the long strip 13 extends to the cartridge 1 and has a sliding groove 14. A graduated groove 15 is provided on the long strip 13.
[0024] A sealing ring is provided on the outer side of the bottom of the sleeve tube 9. The sealing ring 10 is made of medical silicone material, so that the gap between the medicine cartridge 1 and the sleeve tube 9 will not leak during the rotation of the sleeve tube 9 inside the medicine cartridge 1. Moreover, the piston 10 will move inside the sleeve tube 9 during the rotation of the sleeve tube 9 inside the medicine cartridge 1.
[0025] By setting the long strip 13 and the scale groove 15 on the long strip 13, after the sleeve tube 9 rotates inside the cartridge 1, the degree of the scale groove 15 can indicate the depth of rotation of the sleeve tube 9. Combined with the application of squeezing force to the pressing block 8, after the piston 10 moves to the bottom of the sleeve tube 9, the amount of medicine sprayed at one time can be known, making the control of the medicine more convenient.
[0026] Overall process: After the sleeve 9 rotates inside the cartridge 1, the degree of rotation of the sleeve 9 can be determined by the scale groove 15, which indicates the depth of rotation of the sleeve 9, i.e., the amount of medication to be sprayed at once. After the spray assembly 4 is oriented towards the patient's nostrils, pressure is applied to the pressing block 8. As the piston 10 moves to the bottom of the sleeve 9, the liquid inside the cartridge 1 will squeeze one of the sealing blocks 6, thereby connecting the channel 2 with the spray assembly 4. This allows the spray assembly 4 to spray the medication into the patient's nostrils. If the operator presses too high a pressure, the liquid flow rate inside the cartridge 1 will also increase, causing the other sealing block 6 to seal one end of the channel 2, preventing the device from spraying. This prevents the operator from pressing too quickly during the nostril spraying process, reducing the likelihood of the patient experiencing an emergency or sneezing, thus reducing the possibility of medication waste. It also allows the operator to know the amount of medication to be sprayed at once, making medication control more convenient.
[0027] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
