Description

Technical Field

[0001] This utility model relates to hemostasis equipment, and more particularly to a pressure hemostasis device for postoperative oral surgery. Background Technology

[0002] The principle of pressure hemostasis is to apply external pressure to reduce and physically close the ruptured blood vessel, reduce local blood flow, promote blood coagulation and platelet aggregation, and thus achieve hemostasis.

[0003] After a tooth extraction in the dental department, it's common practice to bite down on a cotton ball for 30 minutes to apply pressure and stop the bleeding. However, due to the anesthesia and swelling after the extraction, many patients cannot bite down properly on the cotton ball at the surgical site. Additionally, the inability to swallow saliva while biting down can also cause bleeding. Therefore, the actual hemostatic effect depends on the patient's adherence to the instructions, and the results vary from person to person, making a guaranteed success impossible. Furthermore, crying from children can also lead to poor results.

[0004] Furthermore, for implant patients, due to increasingly advanced technology, many patients opt for multiple implants, rather than just one, depending on their individual circumstances. This leads to an enlarged wound. Clinically, it's common practice to create a homemade "Mickey Mouse" shaped bandage for pressure dressing of the affected area on the jaw and face for the first 24 hours post-surgery to stop bleeding and reduce swelling. However, this method of applying pressure is relatively low and the pressure value is uncertain, relying entirely on the bandaging technique and making precise pressure impossible. Moreover, over time, the bandage tends to loosen, causing it to lose its pressure-adheding effect.

[0005] In addition, how to perform emergency pressure hemostasis and self-rescue in the absence of medical care when there are sudden external injuries to the maxillofacial region, head, and other areas is also a problem that needs to be studied and solved. Utility Model Content

[0006] To address the aforementioned problems in the prior art, this invention provides a post-operative pressure hemostasis device for dentistry, which can be applied to the affected area of ​​the maxillofacial region after surgery and uses air to apply precise pressure to stop bleeding.

[0007] A postoperative pressure hemostasis device for oral surgery includes a control unit, connecting plates, and pressure balloons. The control unit includes a housing, an LCD screen on the upper surface of the housing, a control board, a battery, and an air pump inside the housing. One end of each pair of connecting plates is detachably connected to both sides of the housing. A pair of pressure balloons are respectively connected to the bottom of the connecting plates. The bottom of each pressure balloon has an adhesive layer and a pressure sensor. The air pump is connected to the pressure balloons through pipes. The control unit is electrically connected to the battery, air pump, and pressure sensor.

[0008] The connecting plate includes a connecting section and an installation section connected together. The bottom of the connecting section is used to connect the pressurized airbag, and one end of the installation section is semi-circular. The detachable structure includes an installation groove on the outer wall of the shell and an installation hole in one end of the installation section for fitting into the installation groove. The installation hole has a cut line on one side.

[0009] The connecting plate is a nickel-titanium alloy plate.

[0010] The connecting section of the connecting plate is connected to the pressurized airbag by UV adhesive.

[0011] The pressure sensor is a pressure-sensitive patch.

[0012] The adhesive layer is a nano-aerogel.

[0013] The pressurized airbag is made of silicone.

[0022] The following is a further description of a postoperative pressure hemostasis device for dentistry according to this utility model, such as... Figures 1-7 As shown, it specifically includes a control host 10, a connecting plate 11, and a pressurized airbag 12.

[0023] The control host 10 includes a housing 13, an LCD screen 14 on the upper surface of the housing 13, a control board 15 inside the housing 13, a battery 16, and an air pump 17. The LCD screen 14 can be a touch screen or an LCD screen with control buttons, and can be used to display and set parameters such as pressure limit, pressurization time, and remaining power.

[0024] Battery 16 can be a rechargeable battery, and air pump 17 can be a miniature air pump (such as a DC diaphragm negative pressure pump DC3V). Control board 15 can be an MCU microprocessor, which is electrically connected to battery 16, air pump 17, and pressure sensor 23. It is powered by battery 16 to control the inflation and pressurization of air pump 17.

[0025] One end of each pair of connecting plates 11 is detachably connected to both sides of the housing 13 via a detachable structure. Specifically, the connecting plates 11 can be made of shape memory metals such as nickel-titanium alloy, possessing a certain degree of flexibility. Each connecting plate 11 includes a connecting section 111 and a mounting section 112 connected as one unit. The bottom of the connecting section 111 is connected to the corresponding pressurized airbag 12 via UV adhesive. One end of the mounting section 112 is semi-circular. The detachable structure includes a mounting groove 18 circumferentially located on the outer wall of the housing 13 and a mounting hole 19 located at one end of the mounting section 112 for fitting into the mounting groove 18. A cutting line 20 is provided on one side of the mounting hole 19. The cutting line 20 allows the mounting hole 19 to be opened, facilitating the fitting of the connecting plate 11 into the corresponding mounting groove 18 on the outer wall of the housing 13. As shown in the figure, there are two mounting grooves 18 distributed vertically. Therefore, the mounting section 112 of the connecting plate 11 mounted on the upper mounting groove 18 has a transition step 21, which ensures that the bottom surface of its pressurized airbag 12 is at the same level as the other pressurized airbag 12. Of course, the connecting plate 11 can also be rotated along the housing 13 to adjust the corresponding position.

[0026] The pressure airbag 12 can be made of materials such as silicone or PVC. Its bottom has an adhesive layer 22 and a pressure sensor 23. The adhesive layer 22 can be made of nano-aerogel and is used to adhere to the skin at the affected area. The pressure sensor 23 can be a pressure-sensitive patch (its area is much smaller than the adhesive layer 22, so it does not affect the adhesion or comfort), which can measure the pressure value at the affected area. The air pump 17 is connected to the pressure airbag 12 via tubing 24. The pressure airbag 12 can be designed with quick connectors for easy connection and disconnection from the air pump 17.

[0027] The pressure-based hemostasis device of this invention can be selected and used according to the specific condition of the patient. For example, if the patient is undergoing a lower molar extraction, a double airbag can be used, vertically distributed vertically. The upper airbag is attached to the jaw surface where the lower molar is located, while the lower airbag, under the action of the flexible connecting plate 11, forms a certain angle with the upper airbag (e.g., Figure 1 As shown), place the airbags on the lower part of the corresponding jaw. Then, based on the doctor's experience, set the pressure limit and start the air pump 17 to pressurize both airbags. When the measured pressure value reaches the limit, stop pressurizing and maintain the pressurized state to achieve precise pressure to stop bleeding and reduce swelling by applying pressure directly to the surgical site from the outside. If the patient is undergoing a front tooth extraction, one airbag can be removed, and only a single airbag can be used to apply pressure horizontally to the affected area, i.e., between the upper lip and the nose (as shown). Figure 5 (As shown). If the patient is undergoing emergency hemostasis for upper molars, multiple dental implants, or external trauma, a double-balloon dentistry method can be used. The angle and position of the two balloons are adjusted according to the required pressure location (e.g., for multiple implant wounds or along the direction of an external wound), and then they are placed flat on the affected area and pressure is applied (e.g., ...). Figure 7 (As shown).

[0028] It should be noted that the LCD screen 14, control board 15, battery 16, air pump 17 and pressure sensor 23 mentioned above can all adopt existing technologies, and their control principles can also adopt existing technologies, which will not be elaborated here.

[0029] However, those skilled in the art should recognize that the above embodiments are only used to illustrate the present utility model and are not intended to limit the present utility model. Any changes or modifications to the above embodiments within the scope of the essential spirit of the present utility model will fall within the scope of the claims of the present utility model.
