Chinese patent CN201580050738.1 discloses a powder injection dispenser detachably attached to an injector body that generates an air flow for injecting powder, and injects the powder toward a target portion by the air flow supplied from the injector body, the powder injection dispenser comprising:
a dispenser coupling part for detachably coupling the powder spraying dispenser to the sprayer body;
a duct mounting part mounted at one end of the powder spraying dispenser for accommodating a duct for guiding the powder to a target site;
a container housing part provided at an upper end of the powder spraying dispenser to house a container containing the powder;
a powder discharge port provided at a lower end of the container housing portion so as to transfer powder in the container housing portion to a lower space;
an air inlet formed to be spaced apart from the powder discharge port by a predetermined distance, for transferring air to the container housing part;
an air moving and mixing tube disposed adjacent to the duct mounting portion, the air moving and mixing tube comprising: a guide pipe for guiding the air flow supplied from the injector body to the guide pipe mounting portion; a first passage extending from the guide pipe toward the air inlet, and guiding air in the guide pipe toward the container accommodating section; a second passage extending from the guide pipe toward the powder discharge port, so as to accommodate the powder passing through the powder discharge port inside the guide pipe;
and an opening/closing adjusting portion formed between the air moving and mixing pipe and the container housing portion to move back and forth, thereby moving positions of the two holes provided, thereby simultaneously adjusting communication between the first passage and the air inflow port and communication between the second passage and the powder discharge port.
In this prior art, the air inlet and the powder outlet are opened or closed by sliding the opening/closing adjusting portion back and forth. In addition, in order to prevent negative pressure, the prior art is provided with a first channel for dividing the air flow generated by the air source, so that one part of the air flow enters the medicine bottle through the air inlet to carry powder into the guide tube for spraying, and the other part of the air flow directly enters the guide tube through the first channel to be mixed with the air flow carrying powder for spraying. And when the air flow inlet and the powder discharge outlet are closed, the air flow directly enters the guide tube through the first channel to form positive pressure.
This makes the collision of the air flow from the medicine bottle and the air flow from the first passage at the time of powder ejection, which causes turbulence, making the ejection amount of the powder difficult to control. In addition, because the air flow direction of the first channel is coaxial with the guide pipe, and the air outlet direction of the medicine bottle is vertical to the guide pipe, the air flow of the first channel can cause obstruction to the air outlet of the medicine bottle, so that powder is difficult to enter the guide pipe, and the powder outlet is difficult.
In order to solve the problems in the prior art, as shown in fig. 1 to 3, the present utility model provides a powder injection device, comprising a powder delivery device 3, wherein a mounting seat 12 for mounting a powder container 1, a gas interface 13 for connecting a gas source and a nozzle 6 for injecting powder are arranged on the powder delivery device 3; the powder container 1 and the mounting base 12 can be quickly assembled and disassembled in a threaded manner. Further comprising a powder switch 4 provided on the powder delivery device 3, said powder switch 4 comprising an on and an off state; when the powder switch 4 is in an open state, the gas port 13, the powder container 1 and the nozzle 6 are communicated in sequence, and the gas port 13 and the nozzle 6 are disconnected; when the powder switch 4 is in the closed state, the gas port 13 communicates with the nozzle 6, and the powder container 1 is closed. Thus, only one air flow is used for powder injection, and no interference occurs.
Specifically, the powder delivery device 3 includes a cavity, and the powder switch 4 is disposed in the cavity and is rotatable; the powder switch 4 is provided with a channel I61 for communicating the gas interface 13 with the powder container 1, a channel II62 for communicating the powder container 1 with the nozzle 6 and a channel III63 for communicating the gas interface 13 with the nozzle 6; when the powder switch 4 is turned to the on state, the passage I61 communicates the gas port with the powder container 1, and the passage II62 communicates the powder container 1 with the nozzle 6; when the powder switch 4 is turned to the off state, only the channel III63 communicates the gas port 13 with the nozzle 6.
The on and off states can be simply and quickly switched by rotating the powder switch 4, and the operation is very convenient and quick. Meanwhile, the state is switched by utilizing the rotating mode, and compared with the state in the prior art, the device slides forwards and backwards, so that the occupied space is small, and the volume of the whole device is small.
The powder switch 4 extends out of the powder delivery device 3 and is provided with a knob which is convenient to rotate, and the other side of the switch is provided with a switch fixing seat 5 which is convenient to fix the powder switch 4 on the powder delivery device 3.
In order to avoid blocking the passage between the channel I61 and the powder container 1 by powder, a sealing plate 2 is arranged at the opening of the powder container 1, and at least two sieve holes and a blowing pipe extending into the powder container 1 are arranged on the sealing plate 2; when the powder switch 4 is in the open state, the blow tube is in communication with the passage I61 and the mesh is in communication with the passage II 62. Since the blow tube extends into the powder container 1, powder is less likely to enter the channel I61.
In addition, the arrangement of the sieve holes is for the smoothness of powder discharge, so that powder is prevented from accumulating at the channel II62, and the powder discharge amount is more convenient to control.
In some embodiments, the plurality of mesh openings is disposed directly above the channel II62, and the projection of the plurality of mesh openings onto the horizontal plane is located within the projected area of the channel II62 onto the horizontal plane. Or the sectional area of the channel II62 is larger than the total area of a plurality of sieve holes, so that the smoothness of the powder is ensured.
In order to further improve the smoothness of the powder, the mounting seat 12 is provided with a vibration generating device 7, such as an eccentric motor, which can transmit the vibration to the powder container 1. The high frequency vibration can make the powder become fluffy to avoid blocking the passage after hardening, and also make the powder more easily carried by the air flow.
The nozzle 6 in the present utility model is tapered with its outlet smaller than its inlet. The purpose is that the inlet is provided with a larger cavity, so that the powder is convenient to enter through the airflow, and the outlet is narrowed, so that the powder injection is more concentrated.
In order to make the air flow carrying the powder more unobstructed during spraying, the powder container 1 and the nozzle 6 are arranged coaxially, avoiding powder deposition at the corners. And the gas connection 13 is perpendicular to the axis of the powder container 1 and the nozzle 6, facilitating the arrangement of the gas source.
An air filter 8 is arranged between the air interface 13 and the air source. The filter element of the air filter is made of a hydrophobic material. The air filter 8 plays a role in bidirectional filtration, not only can filter impurities in the air source, but also can prevent powder from entering the air source.
The air source in the present utility model is preferably an air pump 10. The air pump 10 and the air filter 8 are connected by a connecting pipe 9. It is envisioned to also include a battery 11 for powering the air pump 10. Of course, the way in which the direct plug-in wire works is not excluded.
In addition, the tail end of the air pump 10 is provided with a battery compartment, and the battery 11 is rod-shaped and is inserted into the battery compartment. So that the battery compartment and the battery 11 can be used as a handle for easy handling.
When in work, the air source is opened. When powder needs to be sprayed, the powder switch 4 is rotated to an open state, at the moment, the direct passage between the gas port 13 and the nozzle 6 is closed, and gas flow enters the powder container 1 from the gas port 13, then enters the nozzle 6 for spraying after carrying the powder through the powder container 1. When powder is not required to be sprayed, the powder switch 4 is rotated to a closed state, the gas port 13 is only directly communicated with the nozzle 6, the inlet and the outlet of the powder container 1 are closed, and the air flow forms positive pressure in the nozzle to avoid backflow.
The utility model is suitable for scenes with larger powder injection quantity, such as large-area wounds, and can be used for stopping bleeding by injecting a large amount of powder in a short time through gas.
It should be noted that, in this document, the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one … …" does not exclude the presence of other like elements in a process, method, article, or apparatus that comprises the element.
The embodiments of the present utility model have been described above with reference to the accompanying drawings, but the present utility model is not limited to the above-described embodiments, which are merely illustrative and not restrictive, and many forms may be made by those having ordinary skill in the art without departing from the spirit of the present utility model and the scope of the claims, which are to be protected by the present utility model.
