Description

Diabetic wound healing machine {WOUND HEALING APPARATUS}

The present invention relates to a diabetic wound healing device, and more particularly, to efficiently deliver wound removal drugs to the wound using ultrasonic energy, and to effectively replace the components of the healing device that can cause contamination by germs when using the healing device. And diabetic wound healers.

A wound is a condition in which a part of skin or bone is damaged by an external impact or force. On the other hand, wounds that occur in diabetic patients are difficult to treat because there is no clear treatment method.

Attempts have been made to treat wounds occurring in such diabetic patients using ultrasound. Ultrasound is a sound wave with a frequency of more than 20,000 Hz, which uses cavitation, formation of gas bubbles, and unidirectional physiotherapy to detect lesions that are susceptible to chronic wounds in diabetic patients. This is to change the characteristics of acute wound through debridement.

A wound healer that removes wounds from diabetic patients using ultrasound has been developed and used by Muhling, Germany. 1 is a diagram of a conventional diabetic wound healing machine which is currently commercially available from Schölling, Germany. Conventional diabetic wound healer has a shape of a handpiece used in connection with the ultrasonic oscillation circuit, the horn 10, the booster 20, the ultrasonic vibrator 30, the back block 50 and the outer case 60 It is composed of The booster part 20 has a liquid supply port 25 formed in an inclined direction with respect to the longitudinal direction, and a liquid supply pipe 70 is formed from the liquid supply port 25 to the end of the horn 10. Vibration by the ultrasonic vibrator 30 is used to treat the wound by supplying to the wound of the diabetic patient while vibrating the drug in the liquid state supplied through the liquid supply port (25).

Conventional diabetic wound treatment device has the following problems because the liquid supply pipe 70 is formed over the booster 20 and the horn 10. The booster part 20 is formed of an aluminum material, and the horn part 10 is usually formed using a titanium material. In order to form the liquid supply port 25 in the booster part 20, the hole processing is performed in the booster part 20, and then the liquid supply port 25 is inserted into the processed hole. Since the booster 20 and the horn 10 should be able to be fastened to each other while having a liquid supply pipe 70 therein, a resin screw 15 having a hollow portion should be used therein, and thus, precision processing is required.

In addition, at the end of the horn 10 is provided with a tip 17, oxidation occurs in the tip 17 in accordance with the use. Therefore, the tip 17 has to be replaced periodically, but the conventional diabetic wound treatment machine has a disadvantage in that it is difficult to replace because the horn 10 is surrounded by the outer case 60.

In addition, the conventional diabetic wound treatment device is applied to an individual patient, and when contacted with the patient through the tip portion and the liquid supply pipe germs are diffused through the horn 10 to the booster portion 20 to cause contamination. Therefore, sterilization should be performed not only to the horn 10 but also to the booster 20 before use by the next patient. This sterilization usually takes two days, so if you take care of 10 patients a day, the hospital should have a total of 20 diabetic wound treatment machines, which puts a considerable economic burden on the hospital, which in turn increases patient care costs. Will appear.

In addition, the conventional wound healing machine is sprayed to nurses and doctors who treat the wound as the pattern of the sprayed treatment liquid is sprayed in a fan shape having a range of 150 ° to 170 ° and sprayed to a range other than the wound area, thereby causing discomfort. The treatment liquid was sprayed to the floor and the bed with a non-uniform spraying pattern, which required a lot of cleaning time after treatment.

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and an object of the present invention is to provide a diabetic wound healing device having a simple manufacturing process by forming a liquid supply port and a liquid supply pipe only at the mixing portion.

Another object of the present invention is to immediately reuse the contaminated horn when replacing the contaminated horn part with a new one, by limiting the part where contamination is caused by germs to the horn part after treating the individual patient. It is possible to provide a diabetic wound healing device that can increase the utilization of expensive equipment by being reusable by replacing only low-cost horns.

In addition, an object of the present invention is to provide a diabetic wound healing device to improve the shape of the discharge port of the diabetic wound healing device to reduce the spreadability of the treatment liquid sprayed on the wound site so that it can be precisely sprayed only on the wound site.

Diabetic wound healing device according to the present invention for achieving the above object is a terminal made to receive power from the external oscillator as a connector configured to be easily connected and disconnected using a socket; A piezoelectric vibrator amplified by the oscillator to convert the electrical energy input through the connector into mechanical vibration energy; A booster connected to an end of the piezoelectric vibrator as an amplitude conversion device for amplifying the vibration energy output from the piezoelectric vibrator; A horn for further amplifying the vibration energy output from the booster to deliver substantial vibration to the treatment fluid injected into the wound healer; A stud bolt for connecting the booster and the horn; A back block portion for allowing the vibration toward the rear of the ultrasonic vibration generated in both directions by the piezoelectric vibrator to travel forward without being radiated backward; And serve as a handle of the wound healer, and include an outer case for preventing electrical shorts and protecting internals.

The booster has a length of 1 / 2λ (λ = wavelength of ultrasonic vibration), and is configured such that the dimension (width) of the bottom region is smaller than that of the upper region, and the horn is 1 / 2λ (λ = wavelength of ultrasonic vibration). It has a length and is configured such that the dimension (width) of the lower region is smaller than the upper region, the horn has a liquid supply port for injecting the treatment liquid; A liquid supply pipe finally delivering the vibration energy to the treatment liquid injected through the liquid supply port and serving as a movement path of the treatment liquid; And a discharge port for injecting a therapeutic liquid accompanied by high pressure by the vibration energy to the outside, and a connection portion of the booster and the horn is configured to be exposed without being surrounded by the outer case.

In the prior art, manufacturing difficulties such as using an internal hollow resin screw to form a liquid supply pipe over the booster portion and the horn portion, but the diabetic wound healing device according to the present invention forms a liquid supply port and a liquid supply tube at the horn portion. There is an advantage that can be easily manufactured by.

In addition, the diabetic wound healing device according to the present invention is limited to only the horn area contaminated by germs after treating the individual patient, and when using the healing device can completely remove only the contaminated horn when the same diabetes to treat the next patient If you replace the horn of the castle wound healing machine can be reused immediately. Therefore, hospitals do not need to have diabetic wound healers as many as the number of patients, which reduces hospital expenses, which in turn can spread diabetic wound healers, thereby actually benefiting patients.

In addition, the diabetic wound healing device according to the present invention is configured to be inclined in the form of the discharge port in which the treatment fluid is injected to reduce the spreading of the treatment fluid and improve the straightness has an effect that can be accurately injected only to the wound site.

In addition, the diabetic wound healing device according to the present invention amplifies the vibration energy generated from the ultrasonic vibration unit through the booster unit, and unlike the conventional method of transferring the vibration energy to the healing fluid injected into the booster unit and the booster and After completing two amplification processes through the horn, the vibration energy is finally delivered to the therapeutic liquid injected into the horn, so that the therapeutic liquid with higher vibration energy can be injected even with the same power. It has the effect of making it work.

In addition, the diabetic wound healing device according to the present invention is designed to expose the connection portion of the booster and the horn from the outer case has an effect that can facilitate the replacement of the horn for reuse of the healing device.

Hereinafter, with reference to the accompanying drawings will be described in detail the advantages, features and preferred embodiments of the present invention.

2 is a cross-sectional view showing the configuration of a diabetic wound healing device according to the present invention.

The diabetic wound healing device according to the present invention converts electrical energy into mechanical vibration energy and delivers the therapeutic fluid injected into the healing device to inject a liquid with large pressure to the wound site. It is configured to include a case 110, a back block 120, a piezoelectric vibrator 130, a booster 140, a stud bolt 150, and a horn 160.

Looking at the process until the vibration energy is delivered to the treatment fluid injected into the wound healer and sprayed in detail as follows.

First, the connector 100 is a terminal made to receive power from an external oscillator (not shown) and is configured to be easily connected and disconnected using a socket.

The oscillator electrically connected to the connector 100 converts an electrical signal of 50/60 Hz supplied to a general building into an electrical signal of 20 kHz, and amplifies a voltage to supply the piezoelectric vibrator 130. Although the connecting line between the connector 100 and the piezoelectric vibrator 130 is not shown on the drawing shown in FIG. 2, it is to be briefly described that the connection line is substantially connected to the conductor.

The electrical energy amplified by the oscillator and input to the piezoelectric vibrator 130 is converted into mechanical vibration energy by the piezoelectric vibrator 130. As the piezoelectric vibrator 130 resonates at a half wavelength of the use frequency, the piezoelectric ceramic PZT is tightened with a bolt, and when an AC voltage is supplied to the piezoelectric ceramic PZT, the device causes a telescopic movement. Generate vibration.

The vibration extends within 10 μm, and a mechanical amplitude conversion device called a booster 140 is provided between the piezoelectric vibrator 130 and the horn 160 to amplify the vibration energy.

For example, when a 2.0 times booster is attached, the amplitude of 10 占 퐉 transmitted from the piezoelectric vibrator becomes 20 占 퐉 and is transmitted to the horn. The conversion of the amplitude increase and decrease of the booster is obtained by changing the dimensional ratio of the upper region and the lower region of the booster.

Therefore, the booster 140 of the diabetic wound healer according to the present invention is designed to have a length of 1 / 2λ (λ = wavelength of ultrasonic vibration), and the outermost dimension of the lower region 144 as compared with the upper region 142. Width) is made small so that the amplitude of the vibration energy input from the piezoelectric vibrator 130 can be amplified.

The vibration energy amplified by the booster 140 is finally delivered to the horn 160, and the vibration input to the horn 160 is further amplified to substantially apply vibration to the treatment liquid injected into the horn 160. Will be delivered.

The horn 160 is designed to have a length of 1 / 2λ (λ = wavelength of ultrasonic vibration), and the material is made of steel or titanium. Although relatively inexpensive aluminum may be used, steel or titanium is generally used because aluminum has low strength, is easy to wear, and has high reactivity and oxidation.

Like the booster 140, the shape of the horn 160 also configures an outermost diameter (width) ratio between the upper region 162 and the lower region 164 from the center to vary the amplitude of the vibration energy input from the booster 140. It is designed to further amplify.

That is, the outermost diameter dimension (width) of the lower region 164 is smaller than that of the upper region 162 to further amplify the amplitude of the vibration energy input from the booster 140.

A back block 120 is provided at the other end of the piezoelectric vibrator 130 to which the booster is coupled. The back block 120 of the ultrasonic vibration generated in both the front (booster direction) and rear (connector direction) by the piezoelectric vibrator 130, the vibration toward the rear is reflected and not radiated to the rear, the vibration toward the front The amplitude of is to strengthen.

The back block 120 is made of a metal material such as steel and is generally designed to be 1/4 wavelength long.

The back block 120, the piezoelectric vibrator 130, and the booster 140 are configured to penetrate the clamping screw 170 and be connected and fixed to each other.

3 is an amplitude change graph showing that the vibration energy output from the piezoelectric vibrator of the diabetic wound healing device according to the present invention is amplified in the booster, and the vibration energy output from the booster is further amplified in the horn.

As shown in FIG. 3, the electrical energy input to the piezoelectric vibrator 130 is converted into vibration energy having a predetermined amplitude, and the vibration energy output from the piezoelectric vibrator 130 is the maximum of the booster 140. The amplitude was amplified twice through the outer diameter dimension (width) change. The vibration energy amplified through the booster 140 is finally input to the horn 160, and the vibration energy input to the horn 160 likewise changes in the outermost dimension (width) of the horn 160. It can be seen that the amplitude increased further through the part.

As described above, the vibration energy output from the piezoelectric vibrator 130 passes the amplification twice and finally delivers the vibration energy to the treatment liquid injected through the horn 160.

One of the core ideas of the diabetic wound healing device according to the present invention is that a liquid supply port and a liquid supply pipe for injecting a therapeutic liquid and spraying the wound site are formed in the horn 160.

First, the advantages obtained by forming the liquid supply port 180 and the liquid supply pipe 190 in the horn 160 and injecting the therapeutic liquid will be described with reference to the amplitude amplification process described with reference to FIG. 3.

The wound healer according to the present invention amplifies the vibration energy generated from the ultrasonic vibrator 30 through the booster 20 and immediately transfers the vibration energy to the healing liquid injected into the booster 20. Unlike the method, after the two amplification processes (a, b) are completed through the booster 140 and the horn 160, the vibration energy is finally delivered to the treatment liquid injected into the horn 160. It is.

As described above, the wound healer according to the present invention is capable of spraying a therapeutic liquid accompanied by a higher vibration energy than the conventional one even with the same power, and thus, a predetermined amount required for the treatment of the wound site can be achieved even though the power consumption is lower than that of the conventional art. There is an advantage that can generate vibration energy.

Second, the advantages obtained by forming the liquid supply port 180 and the liquid supply pipe 190 in the horn 160 will be described in terms of fabrication of the healing device, disinfection and replacement of the used healing device.

In the prior art, the internal hollow resin screw 15 should be used to form the liquid supply pipe 70 over the booster part 20 and the horn part 10, and the liquid supply pipe 70 may also be provided inside the booster part 20. Although there was a manufacturing complexity to be formed, the diabetic wound healer according to the present invention eliminates the above-mentioned process difficulties and easily wounds by forming the liquid supply port 180 and the liquid supply tube 190 only at the horn 160. It is possible to manufacture a healing device.

In addition, in the conventional case, when the wound healer is used, germs are spread through the horn 10 and the booster 20 along the liquid supply pipe 70 formed in the healer. Therefore, in order to disinfect the conventional wound healer used, not only the horn 10 but also the booster 20 corresponding to the main body of the healer has a problem of increasing the waiting time for reuse of the healer.

However, as the diabetic wound healing device according to the present invention forms the liquid supply port 180 and the supply pipe 190 only in the horn 160 region, the problem that the germs spread and move to the booster 140 does not occur. Since the horn 160 contaminated by germs can be completely removed after treating an individual patient, the horn 160 of the same diabetic wound healing device can be immediately reused to treat the next patient. .

In addition, the connection portion of the horn 160 and the booster 140 fastened by the stud bolt 150 is configured to be exposed from the outer case 110, thereby facilitating the replacement process of the horn 160 of the wound healing device used. To do it.

At the end of the horn 160 of the diabetic wound healing device according to the present invention, a discharge port 200 for injecting a therapeutic liquid accompanied by high pressure by the vibration energy is formed outside. The discharge port 200 according to the present invention is formed in an inclined form so as to reduce the spreadability of the sprayed treatment solution, which is a problem of the conventional wound healing machine, and to spray the treatment solution in a certain straight pattern.

4A and 4B show the injection pictures of the conventional wound healing device and the wound healing device according to the present description. As shown in Figure 4a and Figure 4b, the conventional wound healer (Fig. 4a) shows a large spreadability in the shape of a fan, the wound healing device according to the present invention is configured so that the discharge port 200 has a constant inclined surface (Fig. 4a) 4b) can be seen that the spreadability is significantly reduced and sprayed in a straight pattern.

While the preferred embodiments of the present invention have been described using specific terms, such descriptions are for illustrative purposes only, and it is understood that various changes and modifications may be made without departing from the spirit and scope of the following claims. Should be done.
