Description

Technical Field

[0001] The invention relates to the field of medical atomizers, and in particular to an atomizer with a connector protection function. Background Art

[0002] Nebulization is a common treatment method in pediatrics. At present, when performing nebulization in the hospital, the doctor will give the patient a nebulizer mask and a nebulizer tube. When using it, the patient will insert the nebulizer tube into the connector of the nebulizer for nebulization treatment. However, the following problems were found in actual use:

[0003] 1. One patient has one set of nebulizer mask and nebulizer tube. Usually, the same patient needs multiple courses of treatment, so the same set of nebulizer mask and nebulizer tube needs to be reused. The patient brings them to the hospital for each treatment. After each use, the nebulizer tube needs to be removed from the nebulizer connector and taken home. Since the existing nebulizer connector is connected to the nebulizer outlet in a gap-fit ​​manner, some patients pull violently or use too much force after use, which can easily pull out or tear the nebulizer connector, causing the nebulizer to be unable to be used normally;

[0004] 2. From the outside, because the patient does not understand the nebulizer, he mistakenly thinks that the connector of the nebulizer also needs to be removed, or he does not operate properly when removing it, and mistakenly pulls out the connector of the nebulizer together with the nebulizer tube and takes it away, resulting in the nebulizer cannot be used normally. Especially in pediatrics, it is common for the connector of the nebulizer to be pulled out. The medical staff is busy with work and the patients operate on their own. The medical staff cannot notice the loss of the connector in time, which leads to the loss of the connector of the nebulizer and the nebulizer cannot be used normally. Summary of the invention

[0005] The present invention is intended to provide an atomizer with a connector protection function to solve the problem in the prior art that the connector of the atomizer is easily pulled out.

[0006] In order to achieve the above object, the present invention adopts the following technical scheme:

[0007] The invention discloses an atomizer with a connector protection function, comprising an atomizer body, an atomizer outlet being provided on the atomizer body, the atomizer outlet being detachably connected with a connector, two connecting ears being symmetrically arranged at the inner end of the connector, a receiving groove for accommodating the connecting ears being symmetrically arranged on the inner wall of the atomizer outlet, a clamping block being slidably connected in the receiving groove, the inner end and the outer end of the clamping block being both provided with guiding inclined surfaces, the connecting ears being able to abut against the guiding inclined surfaces, the clamping block sliding along the radial direction of the atomizer outlet, a spring being connected between the clamping block and the atomizer body, the distance between the clamping blocks being smaller than the diameter of the connector when the spring is in a natural state, and the distance between the clamping blocks and the connector being smaller than the length of the connecting ears when the spring is compressed to the maximum extent.

[0008] Preferably, as an improvement, a pressure sensor is provided on the side of the clamping block away from the atomizer outlet, the pressure sensor is electrically connected to the controller, the controller is electrically connected to the reminder module, and the clamping block can trigger the pressure sensor when the spring is compressed.

[0009] Preferably, as an improvement, an infrared sensor is provided on one end of the clamping block facing the outlet of the atomizer, the infrared sensor is electrically connected to the controller, and the controller is also electrically connected to the alarm.

[0010] Preferably, as an improvement, a guide groove is axially arranged on the inner wall of the atomizer outlet, the guide groove and the accommodating groove are staggered by 90 degrees, the guide groove is used to guide the connecting ear, the inner end of the guide groove is connected with an annular connecting groove, the connecting groove is connected with the inner end of the accommodating groove, and two avoidance grooves are symmetrically arranged on the connecting head, the avoidance groove is used to accommodate the clamping block, the avoidance groove passes through the connecting head in the axial direction, the avoidance groove and the connecting ear are staggered by 90 degrees, the avoidance groove can be aligned with the clamping block, and when the spring is in a natural state, the distance between the two clamping blocks is greater than the distance between the two avoidance grooves.

[0011] Preferably, as an improvement, both sides of the avoidance groove transition smoothly to the surface of the connector.

[0012] Preferably, as an improvement, the controller is also electrically connected to a display, the display is mounted on the atomizer body, and the display is used to display a correct disassembly video of the atomizer tube.

[0013] The beneficial effects of this program are:

[0014] 1. In this solution, a connecting ear is arranged on the connecting head, and a clamping block is arranged in the outlet of the nebulizer. When the connecting head is connected to the outlet of the nebulizer, the connecting head can be clamped by the clamping block. At the same time, the clamping block can also limit the connecting ear in the axial direction. The connecting head is doubly positioned from these two aspects, which can effectively prevent the connecting head from being pulled out by the patient, thereby realizing the protection of the connecting head.

[0015] 2. In addition, when the patient pulls out the connector, the connector ear transmits the axial pulling force to the clamping block through the guide bevel, driving the clamping block to separate radially. At this time, the clamping block can trigger the pressure sensor, and the pressure sensor sends a signal to the controller. The controller controls the reminder module to remind the patient not to pull out the connector. The reminder module can be a voice broadcast reminder. At the same time, the controller can also control the display to display the correct disassembly video of the atomizer tube, guide the patient to correctly remove the atomizer tube, and prevent the patient from accidentally pulling out the connector of the atomizer.

[0016] 3. When the connector is inserted into the outlet of the nebulizer, the infrared sensor detects the connector. When the connector is pulled out, the infrared sensor no longer detects the connector, and the infrared sensor sends a signal to the controller. The controller controls the alarm to alert medical staff to come and check. When the connector is accidentally pulled out, the medical staff can be notified in time, thereby preventing the patient from taking the connector away in time and avoiding the loss of the connector.

[0017] 4. When installing the connector, align the avoidance groove with the receiving groove, and align the connecting ear with the guide groove, then insert the connector into the outlet of the atomizer. During insertion, the clamping block does not contact the avoidance groove, and the connector can be inserted smoothly. After the connector is inserted into place, rotate it 90 degrees so that the connecting ear rotates into the receiving groove. At this time, the clamping block can clamp the connector and limit the connector axially to achieve the positioning of the connector. When the connector needs to be pulled out for disinfection or replacement, first pull the connector outward, and use the connecting ear to drive the clamping block to slightly separate a certain distance, so that there is a gap between the clamping block and the connector to facilitate the rotation of the connector, and then rotate it 90 degrees so that the avoidance groove is aligned with the clamping block, and then the connector can be pulled out smoothly. The smooth transition between the avoidance groove and the surface of the connector facilitates the rotation of the connector.

[0018] 5. The reminder module in this solution has two functions: on the one hand, it reminds the patient when he pulls out the connector to stop him from pulling out the connector; on the other hand, when medical staff want to remove the connector, they need to pull the connector outward first. When it is pulled to the reminder module, it means that the connector has reached the position where it can be rotated, which serves as an operation guide and makes it convenient for medical staff to remove the connector.

[0023] The following is further described in detail through specific implementation methods:

[0024] The figure marks in the drawings of the specification include: atomizer body 1, atomizer outlet 11, connecting groove 12, guide groove 13, clamping block 14, guide slope 15, spring 16, accommodating groove 17, connecting head 2, connecting ear 21, avoidance groove 22, display 3, pressure sensor 32.

[0025] like Figure 1 As shown, an atomizer with connector protection function includes an atomizer body 1. The internal structure of the atomizer body 1 is prior art and will not be described in detail. The atomizer body 1 is provided with an atomizer outlet 11, and the atomizer outlet 11 is connected to a connector 2.

[0026] Combination Figure 2 As shown, the connector 2 is used to insert one end (hereinafter referred to as the inner end) of the atomizer outlet 11. Figure 2 The middle and top ends of the connector 2 are integrally formed with two connecting ears 21, and the two connecting ears 21 are symmetrically arranged on the connector 2 with the axis of the connector 2 as the symmetry line. The connector 2 also has two avoidance grooves 22 symmetrically opened, and both ends of the avoidance grooves 22 penetrate the connector 2 in the axial direction, and the two avoidance grooves 22 are staggered with the two connectors 2 at 90 degrees.

[0027] Combination Figure 3 As shown, two receiving grooves 17 for receiving the connecting ear 21 are symmetrically opened along the axial direction on the inner wall of the atomizer outlet 11, and two guide grooves 13 for guiding the connecting ear 21 are also symmetrically opened along the axial direction on the inner wall of the atomizer outlet 11. The guide grooves 13 and the receiving grooves 17 are staggered at 90 degrees. The inner ends of the guide grooves 13 are connected with an annular connecting groove 12, and the connecting grooves 12 are also connected with the receiving grooves 17.

[0028] A clamping block 14 is slidably connected in the receiving groove 17. The inner and outer ends of the clamping block 14 are both processed with guide bevels 15. The clamping block 14 slides along the radial direction of the atomizer outlet 11. A spring 16 is connected between the clamping block 14 and the atomizer body 1. When the spring 16 is in a natural state, the distance between the two clamping blocks 14 is smaller than the diameter of the connector 2 and larger than the distance between the two avoidance grooves 22. The connecting ear 21 can abut against the guide bevel 15. When the spring 16 is compressed to the maximum extent, the distance between the clamping block 14 and the circumferential surface of the connector 2 is smaller than the length of the connecting ear 21.

[0029] A pressure sensor 32 is installed on the side of the clamping block 14 away from the atomizer outlet 11. The pressure sensor 32 is electrically connected to a controller, which is a PLC or a single-chip microcomputer. The controller is electrically connected to a reminder module, an alarm and a display 3. The reminder module uses voice broadcast reminders. The display 3 is installed on the surface of the atomizer body 1. The display 3 is used to display the correct disassembly video of the atomizer tube. An infrared sensor is installed on the end of the clamping block 14 facing the atomizer outlet 11, and the infrared sensor is electrically connected to the controller.

[0030] A method of using an atomizer with a connector protection function is as follows:

[0031] When installing the connector 2, after the avoidance groove 22 is aligned with the receiving groove 17 and the connection ear 21 is aligned with the guide groove 13, the connector 2 is inserted into the atomizer outlet 11. During insertion, since the distance between the two clamping blocks 14 in the natural state of the spring 16 is greater than the distance between the two avoidance grooves 22, the clamping block 14 will not contact the avoidance groove 22 during insertion, and the connector 2 can be smoothly inserted. The connecting ear 21 is located in the guide groove 13, and the guide groove 13 guides the connecting ear 21 to improve the installation stability. After the connecting ear 21 is inserted and moves into the connecting groove 12, it cannot be inserted further. At this time, the connector 2 is rotated 90 degrees so that the connecting ear 21 is rotated to be aligned axially with the receiving groove 17, that is, the connecting ear 21 is aligned axially with the clamping block 14. After the rotation, the avoidance groove 22 and the clamping block 14 are offset by 90 degrees, and the clamping block 14 is clamped on the connector 2, that is, Figure 4 In the state shown, the connector 2 is clamped, and on this basis, the clamping block 14 also limits the connecting ear 21 in the axial direction, thereby achieving a stable connection of the connector 2 from these two directions.

[0032] When the patient pulls out the connector 2, the connecting ear 21 contacts the guiding bevel 15 at the inner end of the clamping block 14, and the two clamping blocks 14 are slightly separated by a certain distance. However, since the distance between the clamping block 14 and the connector 2 is less than the length of the connecting ear 21 when the spring 16 is compressed to the maximum extent, the clamping block 14 can block the connecting ear 21 in the axial direction regardless of how the spring 16 is compressed, thereby preventing the connector 2 from being pulled out by the patient. In order to avoid damage to the connecting ear 21 and other structures due to violent pulling, when the patient pulls out the connector 2, so that the two clamping blocks 14 are slightly separated by a certain distance, the clamping block 14 can trigger the pressure sensor 32, and the pressure sensor 32 sends a signal to the controller, and the controller controls the voice broadcast to play a reminder voice to remind the patient not to pull out the connector 2. At the same time, the controller can also control the display 3 to display a video of the instruction on how to correctly remove the nebulizer tube to guide the patient to remove the nebulizer tube.

[0033] When connector 2 is accidentally unplugged, the infrared sensor cannot detect connector 2, and the infrared sensor sends a signal to the controller. The controller controls the alarm to alert medical staff to come and check. It can give timely reminders when connector 2 is unplugged, thereby preventing the patient from taking connector 2 away and avoiding the loss of connector 2.

[0034] When the connector 2 needs to be pulled out for disinfection or replacement, the medical staff can first pull the connector 2 outward for a certain distance, so that the connector 2 drives the clamping block 14 to separate a certain distance, and trigger the voice reminder. At this time, the clamping block 14 is separated by a certain distance, and a gap is formed between the clamping block 14 and the connector 2, so that the connector 2 can rotate. Then rotate the connector 2 90 degrees, so that the avoidance groove 22 is aligned with the clamping block 14, and the connecting ear 21 is aligned with the guide groove 13 in the axial direction. At this time, the clamping block 14 does not contact the avoidance groove 22, and the connector 2 can be pulled out smoothly. In actual use, the medical staff rotates the connector 2 based on the voice reminder, which improves the convenience of operation.

[0035] The above is only an embodiment of the present invention, and the common knowledge such as the known specific technical solutions and / or characteristics in the solution is not described in detail here. It should be pointed out that for those skilled in the art, without departing from the technical solution of the present invention, several modifications and improvements can be made, which should also be regarded as the protection scope of the present invention, and these will not affect the effect of the implementation of the present invention and the practicality of the patent.
