Description
Technical Field
The present invention relates to a counter with a locking mechanism. The invention also relates to a sprayer comprising the counter, mainly for inhalation administration. Belongs to the technical field of medical appliances.
Background
A hand-held inhalation nebulizer is a device that is used by a patient for a long period of time without supervision. In some cases, such as asthmatics, it is important for the user to ensure that there is an adequate supply of medicament in the nebulizer. Therefore, it is increasingly common in commercial products to provide inhalation nebulizers with counting devices. In addition, sprayers with self-locking function are increasingly common in the market, namely, the sprayers can be self-locked and cannot be reused after the use times of the sprayers are used up. The self-locking function can ensure that each functional component of the sprayer can be safely used during normal use, and safety risks caused by factors such as aging and damage of the functional component during out-of-date use are prevented. Such a self-locking device is beneficial for maintaining the safety of the sprayer from a technical, medical or hygienic point of view.
CN1678406a discloses a locking device for a latching tensioner with a spring operated drive, mounted in a two-part housing which is rotatable relative to each other and lockable by a pre-tensioned spring plate 7a (fig. 1). The locking function is achieved by pushing the pretensioned spring plate 7a from the rest position into the housing wall recess 4 by means of the push rod 8 a. Since the push rod 8a can be mounted on the slide of the counter, the locking device will fail only under a force that can damage the device.
CN 101203259a discloses a fluid sprayer whose counting or detecting means comprises a rotating threaded rod 66 (fig. 34) mounted on the outside of the lower housing, a slide engaged on the threaded rod 66 moving up the threaded rod 66 with rotation between the upper and lower housings of the device, the patient being able to make a rough count by the position of the slide. When the upper and lower housings are relatively rotated, the retainer 6 (fig. 2) therein is moved downward from the initial position, and compresses the drive spring 7, and after releasing the drive spring 7, the retainer 6 is then moved upward to the initial position.
The current common medicine sprayer device with the counting and self-locking functions is mainly realized by combining the two embodiments. The design principle of the counting and locking mechanism is as follows: after the preset number of actuations is completed, the locking mechanism is triggered by a push rod on its counter slider. However, as the threaded rod is arranged outside the shell, the patient can lose the counting and self-locking functions by damaging the threaded rod for multiple uses. In this case, the safety of the use of the sprayer is easily lost: all parts in the sprayer have limited service life, if the parts are used continuously after the safety times are exceeded, the dosing precision of the sprayer cannot be guaranteed under the condition that the parts are worn, and therefore disease control of a patient can be affected, and even the harm of excessive medicine is brought. That is, because the counting and locking mechanism cannot be accurately locked, patients may have the situation that the number of times exceeds a preset number when the sprayer is actually used, and potential safety hazards are brought to the medication of the patients.
Disclosure of Invention
The invention provides a counter with a locking mechanism and a sprayer comprising the counter. The invention reforms the inside of the relative rotation position of the two shells and the fixer of the fluid container (namely the built-in medicine bottle) on the basis of the main structures of the upper shell and the lower shell of the existing sprayer, and a counting and self-locking device is added, so that the use times can not be increased by artificial damage after the assembly; and the patient can see the digital mark on the counting ring through the observation window, the indication device finishes the normal use, such as 60 preset pressing times, and the locking is accurately realized after the preset actuation times are finished.

The transmission shaft is made of metal, preferably stainless steel. The transmission shaft front end sets up circular-arc protruding to can exert anticipated functional action when it contacts with friction bullet arm, namely: increasing friction at the joint and transmitting pressure to the greatest extent. Meanwhile, when the counter reaches the preset times, the arc-shaped protrusions at the front end of the transmission shaft are arranged, so that the counter can be more easily penetrated into the locking hole, and accurate locking is realized.
The elastic force range of the micro spring of the counter with the locking mechanism meets the elastic force transmission requirement of the counter on the micro spring. In some preferred embodiments, the micro-spring has a spring force in the range of 1 to 10N. In other preferred embodiments, the micro-spring is a metal, preferably stainless steel.
In the counter with the locking mechanism, in some preferred embodiments, a longitudinal moving groove is formed on the inner wall of the lower shell of the sprayer, and the transmission shaft moves up and down in the moving groove. According to the counter, the special moving groove is formed for the up-and-down movement of the transmission shaft, so that the effect of positioning and fixing is achieved on one hand, the up-and-down movement of the transmission shaft is smoother on the other hand, unnecessary elastic loss is reduced, and the friction force output of the transmission shaft is ensured.
In another aspect the invention provides a nebulizer comprising a counter according to any one of the preceding claims.
In the prior art, a transmission shaft seat (named as a fixer in some prior arts) reciprocates up and down in a lower shell of the sprayer, is used for fixing a fluid container in the sprayer and realizing the action of extracting the fluid in the container. The invention is based on the original function of the existing fixer, the installation position of the transmission shaft-micro spring mechanism is added, the transmission shaft seat is modified, and the functions of transmission, locking, counting and the like are realized by matching with the friction spring arm and the counting ring.
The sprayer with the counter can count and display the actuation times of the sprayer, is convenient to use, is easy to observe, and has good patient compliance.
The lower shell of the sprayer is provided with a friction spring arm which is contacted with the counting ring and pushes the counting ring to rotate by a relative position when the upper shell and the lower shell rotate relatively.
Each time the sprayer is actuated, the counter ring will rotate relative to each other at a constant angle about the upper housing. When the pressure transmitted to the friction spring arm by the transmission shaft is pressed towards the locking hole direction after the preset actuation times are reached, the friction spring arm is easily broken at the middle transverse notch, the transmission shaft penetrates into the locking hole of the counting ring, thus realizing self-locking, realizing accurate locking of the upper shell and the lower shell of the sprayer, ensuring the use safety of the sprayer, and preventing the sprayer from being continuously used.
The counter with the locking function has the following beneficial effects:
1. The preset actuation times of the counter can be adjusted at one time based on the initial position of the counting ring during assembly according to the specific requirement of the medicine on the spraying times, and additional adjustment is not needed, so that the cost is saved.
