Description

Technical Field

[0001] The invention relates to the technical field of medical devices, and in particular to an infusion pressurized hemostatic patch. Background Art

[0002] Intravenous infusion technology is one of the most commonly used, most direct and safest clinical treatment methods. Since the infusion needs to be injected intravenously, it is inevitable that an infusion needle hole will be formed on the patient's body surface. When the patient has finished the infusion, since the infusion needle hole is difficult to coagulate quickly, the doctor requires the weak patient or non-professional relatives and friends to press the needle hole. If the pressure is not in place or the pressing time is too short, it is easy for the infusion needle hole to continue bleeding, bruising and safety hazards. However, in the process of pressing the infusion needle hole, the movement of the patient or medical staff will be restricted. If the patient is in a hurry to relieve himself, wear, or organize daily necessities and luggage, the action of pressing the infusion needle hole will cause serious inconvenience.

[0003] Therefore, it is hoped to design a device that can free the hands of patients or medical staff and continuously press the infusion needle hole without the help of others. Summary of the invention

[0004] The purpose of the present invention is to provide an infusion pressurized hemostatic patch, which is suitable for patients to operate by themselves, improves the work efficiency of nursing staff, does not require continuous pressure by people, is easy to use, has good hemostatic effect, and has a safety protection function.

[0007] As a preferred solution, the two side edges of the pressure plate are raised to form a clamping wall, and a first hook is provided on the clamping wall. The two side edges of the pressure release plate are provided with a decompression handle. The end of the decompression handle that extends beyond the upper surface of the pressure release plate is a pressing portion, and the end that extends beyond the lower surface of the pressure release plate forms a second hook. The first hook and the second hook cooperate with a snap to form a locking structure. After squeezing the pressing portions on both sides, the decompression handle elastically tilts, and the first hook and the second hook disengage and unlock.

[0008] The reset member is an arched spring sheet, the top of the arched spring sheet is in abutment contact with one of the pressure plate and the pressure release plate, and the arched edge is in abutment contact with the other of the two.

[0009] Among them, a limiting clamping plate is arranged on the pressure plate, and a limiting groove is arranged on the arch spring piece corresponding to the limiting clamping plate. The arch spring piece is limited by the limiting clamping plate and prevented from falling out.

[0010] Alternatively, the reset member is an arched spring piece, the arch of the arched spring piece is fixedly connected to the pressure plate, and the pressure release plate, the decompression handle and the reset member are integrally formed using medical materials.

[0026] Embodiment 1:

[0027] See also Figure 1 As shown, this embodiment provides an infusion pressurized hemostatic patch, which mainly includes a medical tape 1, a sterilization and anti-inflammatory block 2 and a pressurizing device 3.

[0028] The pressurizing device 3 includes a pressurizing plate 31, a pressure release plate 32 and a reset member 33. The pressurizing plate 31 and the pressure release plate 32 are locked relatively still by a locking structure, and the reset member 33 is sandwiched between the pressurizing plate 31 and the pressure release plate 32. At this time, the pressurizing device 3 is in an energy storage state, and all components are made of medical materials.

[0029] The sterilization and anti-inflammatory block 2 is arranged outside the pressure plate 31 and is close to the bleeding opening of the hemostasis part. The sterilization and anti-inflammatory block 2 is made of medical flexible and sterile materials, which can be one or more of sterilization expansion sponge, heavy foam sponge, and wood pulp sponge, and can be attached with anti-inflammatory and bactericidal drugs. The size is determined according to actual medical needs.

[0030] The medical tape 1 is attached to the outer side of the pressure release plate 32 and to the part to be hemostatic. The medical tape 1 is made of non-woven fabric, plain cloth, medical paper and low-sensitivity pressure-sensitive adhesive, and its length is suitable to wrap around the wrist, ankle and other limbs.

[0031] When the lock structure is unlocked, the pressurizing device 3 is in an energy-releasing state, and the reset member 33 enlarges the relative distance between the pressurizing plate 31 and the pressure-releasing plate 32 , thereby providing continuous pressing force for the sterilization and anti-inflammatory block 2 to the bleeding opening.

[0032] In addition, the surfaces of the medical tape 1 and the sterilization and anti-inflammatory block 2 are adhered with release paper 4 to ensure the cleanness of the use surface, and the release paper 4 is provided with a paper head 41 for easy peeling before use. In order to prevent the drug on the sterilization and anti-inflammatory block 2 from being contaminated, a layer of isolation paper 5 can be provided between it and the release paper 4.

[0033] Among them, the release paper 4 is preferably arranged in a segmented form. The tape close to the sterilization and anti-inflammatory block 2 is used to wrap and fix the anti-inflammatory block. The extended section of the medical tape 1 is folded and stored, and a paper head 41 is also provided at the folded part, so that part of the tape can be used in advance during infusion, and the remaining length of the tape can be glued to the skin as needed after the infusion is completed.

[0034] Specific use: When the patient is infused, peel off the release paper 4 at the sterilization and anti-inflammatory block 2, then cover the sterilization and anti-inflammatory block 2 together with the pressure device 3 to the infusion wound, and then stick part of the medical tape 1 to the patient's skin; after the infusion is completed, the nurse pulls out the infusion needle, and after the infusion is completed, the remaining length of the tape is glued to the skin as needed, and the pressure device 3 is unlocked. The pressure device 3 exerts continuous pressure on the sterilization and anti-inflammatory block 2 to achieve the purpose of hemostasis. After use, tear off the medical tape 1 to remove it.

[0035] Embodiment 2:

[0036] See also Figure 2 and 3 As shown, this embodiment provides an infusion pressurized hemostatic patch, and the pressurizing device is further designed on the basis of Example 1.

[0037] In the pressurizing device 3', the two side edges of the pressurizing plate 31' are raised to form a clamping wall, and a first hook 34' is provided on the clamping wall. The two side edges of the pressure release plate 32' are provided with a decompression handle 35'. The end of the decompression handle 35' that extends beyond the upper plate surface of the pressure release plate 32' is a pressing portion 36', and the end that extends beyond the lower plate surface of the pressure release plate 32' forms a second hook 37'. The first hook 34' and the second hook 37' cooperate with the buckle to form a locking structure. After squeezing the pressing portions 36' on both sides, the decompression handle 35' elastically tilts, and the first hook 34' and the second hook 37' are disengaged and unlocked.

[0038] The reset member 33' can be an elastic member such as a spring, and is preferably an arched spring sheet, the top of which abuts against one of the pressure plate 31' and the pressure release plate 32', and the arch side abuts against the other of the two, thereby relying on the elastic force of the arched spring sheet to achieve energy storage and release.

[0039] Taking the arch top of the arch spring piece against the pressure release plate 32' as an example, a limiting card plate 38' is set on the pressure plate 31', and the limiting card plate 38' can be set in the middle or on both sides. Here, setting it in the middle position is taken as an example. A limiting groove 39' is opened on the arch spring piece corresponding to the limiting card plate 38', and the arch spring piece is limited by the limiting card plate 38' and prevented from falling out.

[0040] When leaving the factory or before use, the first hook 34' and the second hook 37' should be buckled together, and the arched spring piece is compressed between the pressure plate 31' and the pressure release plate 32' to be straight; when in use, the sterilization and anti-inflammatory block 2 is flatly placed on the needle port, and the infusion needle is pulled out after the infusion is completed. The medical tape 1 is used to stick the limb flatly, and then the two decompression handles 35' are squeezed toward the middle, and the two hooks are unfastened. The elastic force of the arched spring piece to restore the arch indirectly acts on the sterilization and anti-inflammatory block 2, thereby achieving the purpose of pressing to stop bleeding.

[0041] Embodiment 3:

[0042] See also Figure 4 and 5 As shown, this embodiment provides an infusion pressurized hemostatic patch, and the pressurizing device is further designed on the basis of Example 2.

[0043] Different from the second embodiment, the reset member 33' is an arched spring sheet, the arch top of the arched spring sheet is fixedly connected to the pressure plate 31', the arch edge is in contact with the pressure plate 31' and deforms outward when subjected to force, and the pressure release plate 32', the decompression handle 35', and the reset member 33' are integrally formed with medical materials, so that the setting of the limit card plate 38' and the limit groove 39' can be omitted, and the pressing force can still be provided. The rest of the structure is the same as that in the second embodiment.

[0044] Embodiment 4:

[0045] See also Figure 6 As shown, this embodiment provides an infusion pressurized hemostatic patch, and the pressurizing device is further designed on the basis of Example 1.

[0046] In the pressurizing device 3", a clamping column 34" is provided on the pressurizing plate 31" and is directed toward the pressure release plate 32", and several clamping columns 34" are located on the same circumference. In this embodiment, three clamping columns 34" are taken as an example, and a hook portion 35" is provided on the clamping column 34", and a travel groove 36" is provided on the pressure release plate 32" corresponding to the clamping column 34", and the shape of each travel groove 36" is an arc segment on the same circumference, and a hanging plate 37" is provided in the travel groove 36", when the hook portion 35" of the clamping column 34" is buckled on the hanging plate 37", the pressurizing plate 31" and the pressure release plate 32" are axially locked; when the pressure release plate 32" is rotated relative to the pressure plate 31" by a set angle, the hook portion 35" of the clamping column 34" is disengaged and unlocked from the hanging plate 37".

[0047] The reset member 33" here is preferably a pressure tower spring. The advantage of the tower spring is that the compression height can be reduced, thereby controlling the thickness of the pressure device 3". Countersunk holes 38" are provided on the contact surfaces of the pressure plate 31" and the pressure release plate 32" corresponding to the pressure tower spring to facilitate the positioning of the pressure tower spring. In addition, in order to facilitate the pressing and rotating operations of the pressure plate 31" and the pressure release plate 32", protrusions 39" that are easy to operate can be set on the edges of the plates.

[0048] It should be noted that the setting angle here is less than 45 degrees. Since the rotation angle is small, there is no need to worry about the medical tape 1 affecting the operation after sticking.

[0049] When leaving the factory or before use, the pressure plate 31" and the pressure release plate 32" are kept axially locked, and the pressure tower spring is clamped therein; when in use, the sterilization and anti-inflammatory block 2 is placed flat on the needle port, and the infusion needle is pulled out after the infusion is completed. The medical tape 1 is used to stick the limb flatly, and then the pressure release plate 32" is rotated at a certain angle so that the hook 35" of the clamping column 34" is disengaged and unlocked from the hanging plate 37", and the elastic force of the pressure tower spring indirectly acts on the sterilization and anti-inflammatory block 2, thereby achieving the purpose of pressing to stop bleeding.

[0050] In summary, the above-mentioned infusion pressurized hemostatic patch binds the energy storage pressurizing device to the sterilization and anti-inflammatory block, unlocks the pressurizing device to generate squeezing force on the sterilization and anti-inflammatory block, and thus presses the sterilization and anti-inflammatory block on the infusion wound, effectively preventing bleeding, reducing bruises, protecting patient safety, and increasing the healing speed. It can also ensure the pressing effect, and the patient can easily complete the operation by himself, freeing the hands of the patient or medical staff, and the hemostatic effect is obvious.

[0051] The above embodiments are only to illustrate the basic principles and characteristics of the present invention. The present invention is not limited by the above examples. Without departing from the spirit and scope of the present invention, the present invention may be subject to various changes and modifications, which are within the scope of the present invention.
