Description

The utility model relates to medicine, in particular to a device for preparing intraosseous infusion, and can be used to quickly prepare for intraosseous drug delivery.

For rapid intraosseous access, there are several types of devices that differ in principle of action:

hand trocars;

stern access devices (e.g. FASTI, URL: https://paramedic.top/shop/fast/);

syringe guns (e.g. B.I.G. Syringe Gun for intraosseous injection, URL: http://www.surv24.ru/product/shprits-pistolet-b-i-g-dlya-vnutrikostnykh-inektsiy-bone-injection-gun/);

drills to prepare for intraosseous infusion (e.g., EZ-IO Intraosseous Access System, URL: https: //xn--80aaouxs0b.xn--80asehdb/store/other/vsyo-dlya-infuzii/pistolet-dlya-vnutrikostnoy-inekcii- ez-io /).

Currently, the use of manual trocars is minimized due to a large number of restrictions and difficulty in use, as well as a relatively high risk of injury. With sternal access, as a rule, spring-type devices are used, during which the needle enters the sternum with pressure on the device. The disadvantage of this method of administration is the risk of injury to the sternum. When using a syringe gun, the introduction of the needle into the bone is achieved using a spring mechanism. Such devices are quite effective, but they are not without drawbacks: one-time use and a high risk of injury. The most effective devices in terms of their functionality and atraumaticity are drills for preparation for intraosseous infusion, such devices are intended for use in combination with disposable needles.

The difference between drills designed to prepare for intraosseous infusion from conventional electric drills is, first of all, compactness. This is achieved through the use of gear motors with lower power and batteries with low capacity, which leads to their small size. The compactness of drills designed to prepare for intraosseous infusion is important both for storage and transportation (for example, in one of the departments of the evacuation module), and for use. Manipulating a large tool is more difficult, which reduces the speed and accuracy of the needle insertion. Thus, the shape of the body of the device for preparing for intraosseous infusion, its components and their location have a great impact on its effectiveness.

A device for preparing for intraosseous infusion (CN 208838862, publ. 05/10/2019) is known, including a body, a needle, a control module, a gear motor, a gear motor shaft, buttons, a backlight, a battery and a battery cover. The device is equipped with two lighting elements located on the body (from different sides relative to the needle) at the tip. The device can operate in three modes with different speed ranges: 1800-2000 rpm; from 1500-1600 rpm; 1100-1200 rpm. This device was taken as a prototype, since it is the closest in technical essence to the claimed utility model.

The disadvantage of the prototype is the relatively low ease of use, as well as the low speed and quality of preparation for intraosseous infusion. The flat surface of the case below the power button leads to undesirable sliding of the device in the hands of the user, which is further complicated by the location of the speed control button at the top of the case. In addition, this design does not allow manipulation of the device with one hand. All this negatively affects the speed and quality (due to possible failure to reach the right place) of preparation for intraosseous infusion. In addition, the prototype does not provide for the use of non-slip materials, which also negatively affects the ease of use.

The technical problem lies in the need to develop an effective and small-sized device for preparing for intraosseous infusion with an intuitive interface, devoid of the above disadvantages.

The technical result consists in increasing the usability while maintaining the small dimensions of the device.

The technical result is achieved in that in a device for preparing for intraosseous infusion containing an L-shaped body consisting of a handle and a main part, as well as a gear motor with a shaft located in the main part of the body and connected to the control module and the battery located in the handle and interconnected, while on the outside of the main part of the body on its distal end surface there is a tip mated to the shaft of the gear motor, and located along the perimeter of the end surface of the main part lighting elements, while on the surface of the handle near the inner corner of the L-shaped body there is a start button connected to the control module, according to a utility model, on the rear end surface of the main part there is a power button connected to the control module, while on the surface of the handle below start button made recesses under the fingers.

The execution of the power button of the device connected to the control module, and located on the rear end surface of the main part, provides increased ease of use due to the fact that at the time when the user takes the device in his hand, the power button is near his thumb. This ensures the intuitiveness of the device interface and positively affects the ease of use and the speed of preparation for intraosseous infusion.

Finger grooves on the surface of the handle below the start button also increase the usability of the device. With this design of the handle, the user picks up the device in such a way that his fingers (middle and ring) inevitably end up in the recesses. In this case, his index finger is near the start button, and the thumb is near the power button. All this significantly increases the speed of preparation for intraosseous infusion. In addition, the location of the fingers in special recesses significantly reduces the risk of the device housing sliding in the user's hands, which allows for quick and accurate preparation for infusion. In the most preferred embodiment of the utility model, the start button and power button, as well as finger recesses are made of rubber, which further reduces the risk of slipping in the hands and increases convenience.

Also, in the most preferred embodiment of the utility model, the case is made collapsible, which further increases the convenience of operation due to simplification of maintenance and the possibility of replacing any element when it fails (increase maintainability).

The inventive device is illustrated by drawings, where in FIG. 1 shows the inventive device, a side view in section, in FIG. 2 presents a photograph of the inventive device, and in FIG. 3 is a photograph of a device with a needle attached to a tip.

A device for preparing for intraosseous infusion contains an L-shaped body (in the form of a gun), consisting of a handle 1 and the main part 2. Inside the handle 1 is a control module 3 (represents a computer), which is responsible for the operation of all mechanisms of the device and for the state of the battery 4 , also located in the handle 1. In the device, it is preferable to use a lithium-ion battery. Also inside the main part 2 there is a gear motor 5 connected to the control module 3 and the battery 4, as well as to the shaft 6. The shaft 6 contains a tip 7, designed to install the needle and preferably made in the form of a pentahedron. The tip 7 is placed outside the main part 2 on its front (working) end surface (preferably in the center). Lighting elements 8 are located around the perimeter of this surface. Preferably, the device is equipped with two lighting elements 8 on the end surface of the main part 2, which are located on opposite edges (this ensures the highest quality illumination at different angles without a shadow field). On the surface of the handle 1, in the region of the inner corner of the L-shaped body, there is a start button 9 connected to the control module 3. On the rear end (opposite working) surface of the main part 2, there is a power button 10 connected to the control module 3. On the inner surface of the handle 1 below the start button 9 there are recesses for fingers 11. Most preferred is the implementation of two recesses 11 under the middle and ring fingers. In addition, it is preferable that the elements of the housing 1, 2 are made of plastic, the buttons 9, 10 are made of rubber, and the recesses 11 are rubberized (or with rubber inserts). An indicator light 12 (two-color) is additionally installed on the (outer) surface of the main body 2 of the housing, connected to the control module 3. The device is also equipped with a charging connector 13, preferably a USB connector, which additionally allows you to make changes to the software of the control module 3 if necessary The USB connector is located in the handle 1 and is closed by a cover 14 located on the end surface of the handle 1. The charging connector 13 is connected to the control module 3 and the battery 4. Separating the housing into the handle 1 and the main part 2 is given for convenience of description and understanding by the specialists of the essence of the device. In this case, the body is made collapsible and assembled using bolts 15. The device is intended for use with special needles for intraosseous infusion (as shown in Fig. 3).

The inventive device operates as follows.

The user takes the device in his hand, while his middle and ring fingers are in the recesses 11, his index finger is on the start button 9, and his thumb is near the power button of the device 10. The user presses the power button of the device 10, after which the control module 3 includes lighting elements 8 and a light indicator 12, which shows the charge level of the battery 4 (sufficient when green light, insufficient when red). If the charge level is insufficient, it is recommended that the devices be charged, for which you should open cover 14 and connect the charger to connector 13. If the charge level is sufficient, the device can be used to prepare for intraosseous infusion. To do this, the user installs the needle on the tip 7, and then installs the device on the area of the victim’s body through which the needle is inserted, and presses the start button 9. In this case, the gear motor 5 transmits torque to the shaft 6, which in turn untwists the tip 7 and, in turn, the needle. At the end of the preparation process for intraosseous infusion, the user releases the start button 9, removes the device.

Thus, the claimed utility model is an effective and small-sized device for preparing for intraosseous infusion with an intuitive interface and increased ease of use.
